Maven jar dependency not found at runtime by OSGi environment - eclipse

I'm building an Eclipse product that requires some external dependencies, which are not bundled as Eclipse plugins.
For example javax.json-1.1.4.jar.
I'm usign a target platform file, with Maven dependency added. This is the relevant part of the .target file:
<location includeDependencyScope="compile" includeSource="true" missingManifest="generate" type="Maven">
<dependencies>
......
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.json</artifactId>
<version>1.1.4</version>
<type>jar</type>
</dependency>
</dependencies>
</location>
The resulting bundle is included from the plugin that uses this Json implementation: this is the MANIFEST of the plugin
Require-Bundle: org.glassfish.javax.json;bundle-version="1.1.4"
The plugin compiles and run normally. The problem happens at runtime, when the Json implementation is loaded:

The javax.json-1.1.4.jar is not found at runtime by the api jar javax.json-api_1.1.4.
The only way I found to make it work is to add the implementation jar to the runtime classpath settings of the plugin, in the Bundle-Classpath:
Bundle-ClassPath: .,
lib/javax.json-1.1.4.jar,
This requires the jar in the lib folder of the plugin, while it is already included from the tartget platform. It should be enough..
Is there a configuration or something to be done to make the OSGi environment recognise the jar as a Maven dependency at runtime?
I have read about Eclipse-BuddyPolicy and DynamicImport-Package but I don't know how to used them in my case, and if they are usefull.
This https://github.com/eclipse-ee4j/jsonp/issues/96 says that it "Should be fixed with javax.json:1.1.4 and jakarta.json:1.1.5" but I don't
get how...

I managed to fix this problem, thanks to the comments in this thread:
https://github.com/eclipse-ee4j/jax-ws-api/issues/90
in particular the last one:
https://github.com/eclipse-ee4j/jax-ws-api/issues/90#issuecomment-952793454
This is related to a veri similar problem I had with the implementation of the
com.sun.xml.ws.spi.ProviderImpl web service provider.
Including the OSGi Resource Locator in the bundle manifest, and the plugin with the actual implementations, make them discoverable at runtime.
This is the dependency in the target platform file:
<dependency>
<groupId>org.glassfish.hk2</groupId>
<artifactId>osgi-resource-locator</artifactId>
<version>2.5.0-b42</version>
<type>jar</type>
</dependency>
In the end, for the Json problem, I switched to the Eclipse Parsson implementation which works at runtime without problems.
These are the needed dependencies in the target platform:
<dependency>
<groupId>org.eclipse.parsson</groupId>
<artifactId>jakarta.json</artifactId>
<version>1.0.0</version>
<type>jar</type>
</dependency>
<dependency>
<groupId>org.eclipse.parsson</groupId>
<artifactId>parsson</artifactId>
<version>1.0.0</version>
<type>jar</type>
</dependency>

How do I update Itext7 to version 7.1.1

This seems like it should be simple but I cannot find anything on how to upgrade to newer versions of itext7. I am using an Eclipse maven project with itext7 version 7.0.4 and would like to update to 7.1.1. However, I can find nothing that tells me how to do that. Neither the Eclipse update menu or the Maven menu has an option to update itext7. Can someone point me to the documentation on how to do an update? TIA.
After answer:
I am not getting the libraries but instead getting conflicts:
I can't seem to post my pom.xml using code tags (I guess the formatter has a problem with XML code because of the <>) but I will include it if someone tells me how. I've uploaded the pom file to DropBox:
pom.xml
(Turning #mkl's and #amedee's comments into an answer)
In your project there is a file pom.xml which contains the Maven project definition. In there is a dependencies section with entries for the iText artifacts (among others). The version is therein. Well, it could also be in a separate dependencies management section or in a parent pom.xml referenced in your file.
As soon as you update the POM file, you can update the Eclipse project configuration in your Eclipse Maven menu. That will, if necessary, automatically download the jar artifacts. If your Eclipse Maven integration is properly configured, that is, and if your computer has proper internet connectivity.
Old versions will remain in your local repository but won't be in the class path anymore.
Also check out our getting started guide. Which contains an example POM snippet.
https://developers.itextpdf.com/itext7/download-and-install-information/Java
If you put your iText version number in POM properties, then you only have to update the value once when you want to upgrade. Like this:
<properties>
<itext.version>7.1.1</itext.version>
</properties>
and then
<dependencies>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>kernel</artifactId>
<version>${itext.version}</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>io</artifactId>
<version>${itext.version}</version>
</dependency>
<dependency>
<groupId>com.itextpdf</groupId>
<artifactId>layout</artifactId>
<version>${itext.version}</version>
</dependency>

Service Component missing in AEM

I am trying to create a project in Eclipse using the AEM Developer Tools plugin. The project is published in AEM server and can be seen in: Websites and CRXDE Lite.
The project was created using Maven Archetype-10 in Eclipse and the default project has two pages in English and French. When I open the page in the Site URL, I get the end page, where the message from the HelloWorldModel class should be displayed, along with the other text. But I don't get the message from the respective class. Instead, I am getting the following error message:
org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.sightly.SightlyException: Cannot find a a file corresponding to class com.pen.mypen.core.models.HelloWorldModel in the repository.
It looks like the Java files in the CORE project are not published or are not visible to the web page. But the 3 packages: Core, Apps, and Content are all published and synchronized in Eclipse. Is there any way to check if the Java package is deployed to AEM server? Please guide me to what I am missing here. Please find the error stack trace below:
Caused by: org.apache.sling.scripting.sightly.SightlyException: Cannot find a a file corresponding to class com.pen.mypen.core.models.HelloWorldModel in the repository.

UPDATE
AEM - 6.2
Eclipse - Luna
Java - 1.8
You can check the following things:
http://SERVER:PORT/system/console/bundles shows all the java bundles that are installed on your AEM machine. Check if your bundle is listed there. If not then it could not be installed => check the error log
If your bundle is listed there, check if it is status is active, if not there might be missing dependencies or stuff like that. => click the bundle name to see more details what went wron, also check the error log.
If the status is active, click on the bundle and see if the package that contains your java class is listed in the Exported Packages section.
If the package is listed, you might need to check the error log (again).
UPDATE (because of AEM 6.2):
The problem with your project is, that with AEM versions prior to 6.2, there was a dependency to javax.inject version 0 whereas now they need version 1 and that's not reflected in the pom.xml.
Just add this to your pom.xml of the core project - that's the only change you'll have to do:
<dependency>
<groupId>javax.inject</groupId>
<artifactId>javax.inject</artifactId>
<version>1</version>
</dependency>
and everything will work. Sorry for the confusion...
In case you are using SlingModels the javax.inject is exposed by the org.apache.sling.models.api
Can you check your pom for the SlingModel dependencies
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.models.api</artifactId>
<version>VERSION_NUMBER</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.models.impl</artifactId>
<version>VERSION_NUMBER</version>
<scope>provided</scope>
</dependency>
Check the VERSION_NUMBER you are using and then in /system/console/bundles verify that the same version bundle is present and Active.
With AEM 6.x the Sling Model bundles are available by default. The 6.0 will have a lower version 1.0.x. Fixing the version either by updating the pom or installing the SlingModel bundles with version VERSION_NUMBER fix your issue.
Update for 6.2
For 6.2 with models with version 1.2.2 use following in dependencies -
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.models.api</artifactId>
<version>1.2.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.sling</groupId>
<artifactId>org.apache.sling.models.impl</artifactId>
<version>1.2.2</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-atinject_1.0_spec</artifactId>
<version>1.0</version>
<scope>provided</scope>
</dependency>
geronimo-atinject_1.0_spec is the one that is exposing javax.inject in sling models 1.2.2
Sharing my solution which will be helpful.
Tested on AEM 6.2 working perfect.
In core pom.xml file add Import-Package tag with "javax.inject;version=0.0.0,*" inside "org.apache.felix" plugin tag.
Following is the sample :
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<!--
<Embed-Dependency>
artifactId1,artifactId2;inline=true
</Embed-Dependency>
-->
<!-- Import any version of javax.inject, to allow running on multiple versions of AEM -->
<Import-Package>javax.inject;version=0.0.0,*</Import-Package>
<Sling-Model-Packages>
com.next.sample_test_impl.core
</Sling-Model-Packages>
</instructions>
</configuration>
</plugin>

No Jar found in /WEB-INF/lib after deploying maven project from eclipse to wildlfy9

I am seeing a very strange behavior of wildfly9.x. Build process goes successful. after clicking on RUN AS -> Run on Server(WildFly9.x). It shows exception like NO class def found.
I have already added dependency in POM.xml and its scope is compile.
POM.xml file:
<dependency>
<groupId>commons-codec</groupId>
<artifactId>commons-codec</artifactId>
<version>1.6</version>
<scope>compile</scope>
</dependency>
Exception:
Caused by: java.lang.ClassNotFoundException: org.apache.commons.codec.binary.Base64 from [Module "deployment.worldportfolio.war:main" from Service Module Loader]
at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:205)
Thanks in advance.
I solved it by myself. If you want to run wildfly server from eclipse IDE so you should follow this a very simple method create lib folder in WEB-INF and place all the required Jars in the lib folder. You are done.

org.hibernate.cfg.beanvalidation.TypeSafeActivator;141) HHH000274: Unable to apply constraints on DDL

I am using JDK 1.7 with Maven 3.0 for my project.
When I have the following in pom.xml
<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>6.0</version>
<scope>compile</scope>
</dependency>
I am getting the following while deploying to Weblogic 10.3.6 integrated with Eclipse
WARN (org.hibernate.cfg.beanvalidation.TypeSafeActivator;141) HHH000274:
Unable to apply constraints on DDL for test.entity.Employee
java.lang.NullPointerException at
org.hibernate.cfg.beanvalidation.TypeSafeActivator.applyDDL(TypeSafeActivator.java:172)
If I remove javaee-api dependency, then I do have issues when I compile project using mvn compile with errors like
[ERROR] /domain/view/EmployeeNameConverter.java:[29,76] cannot access
javax.el.ELContext
class file for javax.el.ELContext not found
[ERROR] /EmployeeNameConverter.java:[28,55] cannot access javax.el.ELResolver
class file for javax.el.ELResolver not found
More details here
How can I resolve this issue?
Like we've worked out in the comments Weblogic 11g doesn't support Java EE6. So one solution can be using Java EE5 instead.

Using Drools on Jetty

I am trying to start up a webapp that uses Drools 5.2.0.M1. I get the following stacktrace on startup:
java.lang.NoSuchMethodError: org.eclipse.jdt.internal.compiler.CompilationResult.getProblems()[Lorg/eclipse/jdt/core/compiler/CategorizedProblem;

I have the jars in my pom:
<dependency>
<groupId>org.drools</groupId>
<artifactId>drools-compiler</artifactId>
<version>5.2.0.M1</version>
</dependency>
<dependency>
<groupId>org.eclipse.jdt.core.compiler</groupId>
<artifactId>ecj</artifactId>
<version>3.5.1</version>
</dependency>
Why Can't it find CompilationResult.getProblems()?
JDT isn't backwards compatible.
Check the drools-compiler pom (of exactly the version you're using) on which version of ecj it depends and use that version. Or don't declare ecj at all, it's a transitive dependency for drools-compiler anyway.
PS: upgrade to drools 5.2.0.CR1 (or final once it's out)
I had a similar problem. I was having a web-app using Jetty 6. Jetty 6 which apparently bringing in a non-compatible version of JDT. After switching to Jetty 7 the problem was solved.
