Publish on Tomcat from Eclipse - eclipse

I have problem when publishing web project on tomcat. I've got this error:
!ENTRY org.eclipse.wst.server.core 4 0 2013-07-17 14:22:41.293
!MESSAGE Could not publish to the server.

But If I turn off Maven's resolve dependencies from Workspace in web project everything works fine.
Any idea
Thanks

I have used m2e plugin instead of m2e-wtp. After installing m2e-wtp it works fine.

I have had a similar issue. In my case, the web app project had a dependency to another library project. An the library project had no facets enabled. So I enabled facets for Java and Utility Module. That seemed to resolve the issue.
It was in Eclipse :
Version: Mars Release (4.5.0)
Build id: 20150621-1200

I guess the problem is solved .. for years now, but it could interest somebody else, facing the same kind of problem with Eclipse.
I use Eclipse Luna, a quite fresh installation (1 month).
I had no problem deploying my webapp when ... today, I suddenly got the same exception (as mentioned above) when publishing the webapp.
I found the problem. For me, it was in the .project file:
<buildCommand>
<name>org.eclipse.ui.externaltools.ExternalToolBuilder</name>
<triggers>full,incremental,</triggers>
<arguments>
<dictionary>
<key>LaunchConfigHandle</key>
<value><project>/.externalToolBuilders/org.eclipse.wst.validation.validationbuilder (1).launch</value>
</dictionary>
</arguments>
</buildCommand>
I don't why, but the line related to externalToolBuilders is wrong: checking my workspace, I figured out that the correct statement is:
<value><project>/.externalToolBuilders/org.eclipse.wst.validation.validationbuilder.launch</value>
After correction, I could publish my webapp.
Hope it could help...
PS: it's not the first time I got exception with Eclipse .. and more that once, I found the solution checking the .project, and comparing it with another .project file, belonging to another application/module that works correctly...

eclipse nullpointer exception for modulare maven project update

I'm using Eclipse 4.4.1 with m2e plugin and the latest gae dependencies. When I import the gae module sample project eclipse tells me that the project configuration is not up to date. If I run the suggested maven -> update project, I get a NPE.
There are a lot of bug reports according NPE on project updates out there. So far I've tried it with mvn eclipse:eclipse or maven project imports, in fresh or existing workspaces but I was never able to get the projects running in eclipse.
Are there any solutions to this?
EDIT:
That is the stacktrace:

You can comment out the appengine-maven-plugin to solve the problem, but by doing that you lose the command-line capabilities of the plugin. You can have the best of both worlds (Eclipse and Maven command-line) by using Maven profiles:
<profiles>
<profile>
<id>gae</id>
<build>
<plugin>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-maven-plugin</artifactId>
<version>${appengine.target.version}</version>
</plugin>
</build>
</profile>
</profiles>
To activate it, for instance, to deploy the project from the command-line, you can do:
mvn appengine:update -P gae
When defining the appengine-maven-plugin only inside a profile, Eclipse won't use it, and the bug goes away. When using the command-line, just remember to activate it using the -P flag.
I had the same problem suddenly appear in one of my projects. Disabling the JPA validator seems to have resolved the issue for now.
Select Windows > Preferences > Validation
Disable the JPA Validator for both Manual validation and Build validation
It might be related to the "The persistence.xml file does not have recognized content" error described in here: www-01.ibm.com/support/docview.wss?uid=swg21616684 .
I had the same issue after updating from Eclipse Kepler (4.3) to Luna (4.4). Commenting out the app-engine-maven plugin from my pom.xml fixed it for me.
<!--
<plugin>
<groupId>com.google.appengine</groupId>
<artifactId>appengine-maven-plugin</artifactId>

I'm able to run and deploy my app without any issues so far.

An internal error occurred during: "Updating Maven Project". java.lang.NullPointerException

I'm developing a Java EE web project. When I try to add a dependency, this error message appears. I use Eclipse Kepler.
An internal error occurred during: "Updating Maven Project". java.lang.NullPointerException
Could you help me?
Thank you.
I solved mine by deleting the .settings folder and .project file in the project and then reimporting the project.
For me worked the answer I found on CodeRanch, by user Maneesh Godbole:
Close eclipse.
Navigate to your "workspace" folder
Ensure the setting on your OS to view hidden files is turned on
Identify and delete the .metadata directory
Restart eclipse
Import project
I've had the same problem in one of my modules.
Running "mvn eclipse:eclipse" in the console/cmd solved the problem for me.
In our instance of this problem, we had pom.xml files where the m2e-specific life cycle mapping configuration
<pluginManagement>
<plugins>
<plugin>
<groupId>org.eclipse.m2e</groupId>
<artifactId>lifecycle-mapping</artifactId>
<version>1.0.0</version>
<configuration>
<lifecycleMappingMetadata>
...
did not have the <version>1.0.0</version> part. When doing a Maven -> Update Project..., this causes the reported NullPointerException without a stack trace. When using a fresh Import... -> Existing Maven Projects, the same exception occurred, but with a stack trace that led me to find the above.
(This is with m2e 1.6.1.20150625-2338 in Eclipse Luna Service Release 2 (4.4.2).)
In case it helps anyone, in addition to deleting .settings and .project, I had to delete .classpath and .factorypath before being able to import the project successfully into Eclipse.
org.eclipse.m2e.core.prefs file is in .settings folder. If you face the problem of
An internal error occurred during: "Updating Maven Project". java.lang.NullPointerException
Delete the project from eclipse then by deleting the .settings folder & .project file in the project -> then re-import the project.
None of the above methods worked for me. This might also arise due to the presence of circular dependency in your eclipse workspace. So if there are any other errors present in any of the other projects in your workspace, try to fix those and then this issue will be gone. This is how i eliminated the error.
This helped me: Project menu -> Clean... -> clean all projects
Eclipse has an error log. There you will see the complete stack trace. In my case it seems to be caused by a bad jar file combined with the java.util.zip libs not throwing a proper exception, just a NullPointerException.
I'm using:
Eclipse Java EE IDE for Web Developers.
Version: Neon.3 Release (4.6.3)
Build id: 20170314-1500
The fix/trick for me was deleting my local repository in ~/.m2/repository in order to remove local dependencies and rebuilding my project in which fresh dependencies are pulled down.
Above solutions did not work for me as the issue with open JDK 13 version
https://github.com/spotify/dockerfile-maven/issues/163
So I degraded to open JDK8 and it works for me
I had the same problem. None of the solutions here worked. I had to completely reinstall eclipse and make a new workspace. Then it worked!
I had this same issue across multiple projects and multiple workspaces, none of the solutions I found online worked for me. I'm using STS and the only thing that worked was to go into my STS directory and add a "-clean" to the top of the STS.ini file. You can then start up your workspace and run maven clean without errors. (you can also remove the -clean tag from the ini file so it doesn't clean everytime you start it)
Hope this helps someone.
The root issue in my case was a file conflict in the .settings folder. So, deleting the .settings folder would have resolved the Maven error, but I wanted to keep some of my local configuration files. I resolved the conflict, then tried a Maven update again and it worked.
I had the same issue ... solution at the end !
here the eclipse log:
java.lang.NullPointerException
at com.google.appengine.eclipse.wtp.maven.GaeRuntimeManager.getGaeRuntime(GaeRuntimeManager.java:85)
at com.google.appengine.eclipse.wtp.maven.GaeRuntimeManager.ensureGaeRuntimeWithSdk(GaeRuntimeManager.java:55)
at com.google.appengine.eclipse.wtp.maven.GaeFacetManager.addGaeFacet(GaeFacetManager.java:59)
at com.google.appengine.eclipse.wtp.maven.GaeProjectConfigurator.configure(GaeProjectConfigurator.java:46)
... it comes from "appengine maven wtp plugin" that try to get the type of GAE runtime, but seems to be null here (... getRuntimeType() --> NPE):
see class com.google.appengine.eclipse.wtp.maven/GaeRuntimeManager.java
private static IRuntime getGaeRuntime(String sdkVersion) {
IRuntime[] runtimes = ServerCore.getRuntimes();
for (IRuntime runtime : runtimes) {
if (runtime != null && **runtime.getRuntimeType()**.equals(GAE_RUNTIME_TYPE)) {
So, if you check in eclipse, Google App Engine is visible , but when you select it you'll see that no SDK is associated ...
SOLUTION:
in red on the screenshot ;-)
I encountered this same symptom and none of the solutions above were helpful. I finally got a stack trace of the problem by importing the ear project again to eclipse, and was able to trace this down to the org.eclipse.m2e.wtp.MavenDeploymentDescriptorManagement which was trying to delete a directory in windows' temp directory called ".mavenDeploymentDescriptorManagement", which caused an irrational NullPointerException from the java.io.File.exists() method, particularly because the code already had successfully done the same thing in a previous method with the same variable, then called file.isFile() without problem.
Checking this out on the file system revealed that the file could only be accessed with administrator privileges. Apparently I had at some point launched eclipse from an administrator console by mistake.
In the end I just made hidden files visible in windows explorer and deleted the temporary file manually, which solved the problem.
Just another possible source of the problem!
I found out that in my case it was the following resource block that caused it:
<project>
<build>
<resources>
<resource>
<directory>${basedir}/../some-folder</directory>
<targetPath>outputFolder</targetPath>
</resource>
<resources>
</build>
</project>
It included a folder from the project folder (the eclipse project is a subfolder of the versioned project folder).
In my case, I could remove the error by removing the block and replacing it with a call to the Build helper Maven plugin:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.9.1</version>
<executions>
<execution>
<id>my-own-very-cool-id-for-this-step</id>
<phase>generate-resources</phase>
<goals>
<goal>add-resource</goal>
</goals>
<configuration>
<resources>
<resource>
<directory>${basedir}/../some-folder</directory>
<targetPath>outputFolder</targetPath>
</resource>
</resources>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
I had to reinstall eclipse, delete .m2 folder and rebuild the jars.
deleting the local maven repository helped me
In my case, the problem was a conflict of derived dependencies that were been used by other dependencies, and some of those derived dependencies versions were not available, maybe because some deploy that i forgot to do because with workspace resolution everything worked, but when moving to other environment all broke suddenly.
And also I was working with version ranges
maven was giving me this error:
Could not resolve dependencies for project
MyProject:MyProject:jar:1.0.0: Could not resolve version conflict
among Dependency-A:1.0.1 -> Dependency-B:1.1.0 ->
Dependency-C:1.0.0, Dependency-X:1.0.1 -> Dependency-Y:1.1.0 -> Dependency-C:1.0.0, Dependency-I:1.0.1 -> Dependency-J:1.1.0 -> Dependency-C:1.0.0
I tried all above and nothing worked, so...
THE SOLUTION: Use LATEST as version in all dependencies, so maven don't need to resolve all dependencies in ranges, wich must be used
with care because if you miss to deploy one of the dependencies the
build will fail
Only I suggest you to use LATEST if you are working with your own dependencies, otherwise in some third party future version, you could find some compilation or runtime errors
Avoid deleting the .metadata folder as it cleans up all settings, run configurations.
Instead, rename the .metadata folder --> Restart eclipse --> Import project
deleting the local .settings folder helped me
solution step is delete following files in project folder
.settings
.project
.classpath
I solved this problem like this: Project -> Clean -> %YOURPROJECT%

nullPointerException when deploy webLogic 12c application

I had this problem and resolved it by removing JSF 2.2 Mojarra 2.2.0 from the application libraries. It only needs to be in the classpath.
In Eclipse, edit properties for the project, go to Project Facets-->Java Server Faces and uncheck "Include libraries with this application" and Apply change.
I deploy from Eclipse (OEPE), same problem here without JSF. Here is what solved my problem:
Quit Eclipse
Delete the workspace's .metadata folder
Launch Eclipse
The same solution worked on NetBeans8. From projects, go to your war project, right click over Libraries > JSF2.2 and click Remove. Rebuild the project and deploy. Remember to deploy as shared library the JSF on WLS.
This seems to be a duplicate of Maven generated ear file fails during deploying weblogic server. Some details about the solution can be found in this post https://roundwheeltech.wordpress.com/2016/06/15/deploying-a-jsf-2-2-to-weblogic-12-1-3/.
Because WebLogic 12.1.3 ships with JSF 2.1, the required JSF jars have to be bundles within the WAR file (specified as dependencies in pom.xml). WebLogic must also be instructed to use the libraries packaged in the WAR file instead of the ones that are provided by the container.
I had the exact same NPE. It was started by an instantiation of an factory that went wrong. I had to remote debug in to find this. An exception in the initialisation of the factory is swallowed and we don't get the real exception.
In my case the problem was antlr.Token and antlr.CommonToken not arriving from the same source. This gave me an ClassCastException. I solved it by moving all libraries from the ear to war to get more control over them.
Edit the file web.xml and put:
<welcome-file-list>
<welcome-file>faces/index.xhtml</welcome-file>
</welcome-file-list>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>/faces/*</url-pattern>

Eclipse FeatureNotFoundException

I have built my project with maven
All builds successful and eclipse properties generation is also successful
But when I open the project in Eclipse 4, I am getting this error
An internal error occurred during: "Loading descriptor for SALYExplorer.".
org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'taglib' not found. (platform:/resource/SALYExplorer/src/main/webapp/WEB-INF/web.xml, 313, 10)
At that location I have some properties
Though the project runs smoothly and everything is fine, just while exploring the project in Navigation pane, Eclipse always throws this error box (quite annoying).
COde at that location
<taglib>
<taglib-uri>xx.tld</taglib-uri>
<taglib-location>/WEB-INF/tld/xx.tld</taglib-location>
</taglib>
and xx definations int it's file
<!DOCTYPE taglib PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1_2.dtd">
<taglib>
<tlib-version>1.0</tlib-version>
<jsp-version>1.2</jsp-version>
.........
</taglib>
The problem is not the taglib at all, it's just a bad error description by Eclipse.
it is the project facet vs. web.xml dtd.. their versions must match!
if the web.xml says:
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
but the project has a
"Dynamic Web Module 2.5"
then this error will occur.. change facet to 2.3 or web.xml to 2.5... in other words: they must match..
I ran into this error while trying to update a maven project in Eclipse (ALT+F5).
web.xml
<web-app xmlns="http://java.sun.com/xml/ns/javaee" version="3.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
and project facet
Dynamic Web Modul 3.0
Here is how I could fix it:
Removed all xmls-schema definition from the web-app element
<web-app>
then update the maven project (ALT+F5).
Re-insert the schema definitions and re-update project (ALT+F5).
According to jsp_2_1.xsd included from web-app_2_5.xsd, taglib tag should be in jsp-config tag:
<xsd:complexType name="jsp-configType">
<xsd:annotation>
<xsd:documentation>
The jsp-configType is used to provide global configuration
information for the JSP files in a web application. It has
two subelements, taglib and jsp-property-group.
</xsd:documentation>
</xsd:annotation>
<xsd:sequence>
<xsd:element name="taglib"
type="javaee:taglibType"
minOccurs="0"
maxOccurs="unbounded"/>
<xsd:element name="jsp-property-group"
type="javaee:jsp-property-groupType"
minOccurs="0"
maxOccurs="unbounded"/>
</xsd:sequence>
<xsd:attribute name="id" type="xsd:ID"/>
When I wrapped taglib in js-config, the error disappeared.
<jsp-config>
<taglib>
<taglib-uri>http://www.springframework.org/tags/form</taglib-uri>
<taglib-location>/WEB-INF/taglibs/spring-form.tld</taglib-location>
</taglib>
</jsp-config>
Previous parsers were probably more lenient. My config: Eclipse Luna, built-in maven 3.2.1, web.xml 2.5, Dynamic Web Project facet 2.5.
For the time being if it's just the annoying Error Message that you want to fix, then as a short-term fix take a look at disabling validation here : Eclipse 'loading descriptor' takes ages
If the above does not work, an alternative would be to use AHK (Autohotkey) which would take slightly more work at your end. (I have been using an AHK script for a couple of years now to get rid of the Eclipse Error popups that I don't care about)
Eclipse Bug 198630 was raised almost 5 years back and in that there is a comment which has an almost identical error message as the OP. (The bug itself was finally closed as not being reproducible).
I have the following questions for you :
Would it be possible for you to show us the Error log ? (To get at the error log you can either take a look at the Error Log View or by looking at the actual file : WORKSPACE_HOME/.metadata/.log. Please take a look at this for more detailed information. )
Are you using any specific Server Adapters like WebLogic or Glassfish ?
I have the following recommendations :
In the eclipse bug thread, the problem was fixed at least once by updating to a specific JST version. Hence, would it be possible for you to run an Eclipse update and see whether the problem is resolved ? (This can be done by going to Help -> Check for Updates)
Would it be possible to try importing the project in Eclipse Indigo (instead of
Juno, which you currently have) and see whether you can reproduce
the problem ? (Eclipse Indigo downloads are available here and I believe you would need the Java EE version)
I just got the same symptoms, with a web-app project using maven. In my case, was related to struts taglib tags in web.xml, and the project having a struts v1.2.9 dependency. I solved the problem by switching to struts v1.3.10. Don't ask why this solved the problem.
If you are in the same situation and you upgrade your struts dependency from 1.2.9 to 1.3.10, be sure to use at least dtd v2.3 in the DOCTYPE declaration of your web.xml:
!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/j2ee/dtds/web-app_2_3.dtd"
or you'll get another problem (your webapp won't startup without an internet connection)
Hope this helps
I suspect that the problem is with Eclipse web Tools Platform and Java EMF Model. Here is an image of a list of plugins including Java EMF Model and JEM stuff from Eclipse Web Tools Platform:

I managed to fix this by removing the validator out of the .project file for each of the projects that had the issue.
I had a similar error using eclipse 4.3 (Kepler), maven 3.1.0, tomcat 6.0.37 and jdk7 (have also jre6 installed), and found a solution to fix it or at least to get rid of the tedious errors by configuring tomcat in eclipse.
In Preferences->Server-> Runtime Environments, define a new run time environment "Apache Tomcat 6.0" and select the jre6 installation from the installed JREs.
Then review the Targeted Runtimes in the project's properties. Apache Tomcat v6.0 should be associated with Java Runtime Environment v1.6 (if not yet defined press new and check that the selected JRE is a java 1.6 runtime).
Hope it helps
I was able to update the project Java facet to 1.5 and the errors stopped.
In my case, this problem got resolved by using the version
org.eclipse.emf.ecore.xmi_2.10.2.v20150123-0348 and org.eclipse.emf.ecore.xmi.source_2.10.2.v20150123-0348 and
org.eclipse.emf.ecore.xmi_2.10.2.v20150123-0348 and
org.eclipse.emf.ecore.xmi.source_2.10.2.v20150123-0348 and
org.eclipse.emf.common_2.10.1.v20150123-0348
jars in the build path.
Earlier jars of old version were being used inspite of new version present.
Right click on the project in Eclipse -> Build Path -> Configure Build Path -> Project Facets -> Uncheck Dynamic Web Module
Note: This approach is good as long you dont plan to run the web-app from within eclipse thru an embedded app server.

How to deploy a library with Java EE 6 / Glassfish 3.x

I have got an EAR with two plain libraries. One of them being scala-library. If I deploy the EAR with Netbeans it works as expected. While this is OK for development the final product should be deployable via the command line. For this I use:
asadmin --user … deploy --upload ./target/…-ear.ear
which fails with:
org.glassfish.api.admin.CommandException: remote failure: Error occurred during deployment: Exception while deploying the app […-ear] : C:\Work\Workspa
ces\…\Glassfish\…\applications\scala-library-2.8.0.jar. Please see server.log for more details.
Befehl deploy fehlgeschlagen.
Searching the net I found out that handling libraries have become more strict with Java EE 6 / Glassfish 3.x and that it is not enough to add them to the lib folder inside the ear any more. Only the author neglected to mention what is needed now.
I found new <module><java> entries for the META-INF\application.xml — but that did not help either:
<module>
<java>scala-library-2.8.0.jar</java>
</module>
So the question: Does anybody know what you have to do to add libraries to an EAR file for Java EE 6 / Glassfish 3.x?
PS: I use Maven to build - if that makes any difference.
Well it seems I found the solution myself (again). After adding a library-directory entry to the end of the META-INF\application.xml the deployment runs thou:
<library-directory>lib</library-directory>
</application>
The strange thing is that lib the default for library-directory. So I guess it must be a bug in Glassfish itself not handling the default correctly. If you use Maven make sure to use bundleDir in your pom.xml so that the libs are place in the right place:
<jarModule>
<groupId>org.scala-lang</groupId>
<artifactId>scala-library</artifactId>
<bundleDir>lib</bundleDir>
</jarModule>
