I'm creating a JSF Web Application using Eclipse and suddenly i got a java.lang.ClassNotFoundException when i deployed my app on the Tomcat Server. I was confused why this happened because all my build path libraries that i had added worked without any problem.
But then i checked the deployed .war file to see whether all my .jar's were there. And to my surprise it wasn't there. And it was the case for java.lang.ClassNotFoundException i received. Then i tried adding other libraries. Non of them were copied to the deploying .war file source. But i could use them in my workspace.
Then i created a new project and copied all the sources from my previous. And then it worked fine. It copied everything to the .war file.
But then i had to use another library and i added it to the build path. Then the same issue was raised. That jar file was not copied to the .war file. And anything i added or if i remove something that already worked and add it again, it stops working because those files will also no be copied to the deploying war.
Is this a an Eclipse bug or is there a Configuration that limits the use of libraries? Any JSF configurations? Can anyone help me on this?
I'm using Tomcat 8, JSF 2.2 with Primefaces 5.1
i have written an application on my pc using CDI as the backing bean for jsf, the application works completely fine.
Now i setup everything on a new pc, installed glassfish 4.1, setup eclipse kepler by putting the installed jre as jdk7 from the glassfish folder.
when i make a war for the application on my pc and deploy it onto the glassfish server on the other pc everything works fine.
now i tried taking the project from my pc and imported it onto the new pc. the eclipse on the new pc wont recognize import javax.enterprise.context.SessionScoped; giving compiler error that this annotation is not available.
The import javax.enterprise.context cannot be resolved
it doesnt recognize javax.enterprise.context.* at all. like CDI is not available. i am using JDK 7 which contains JSR 346, so i am completely confused what the issue could be.
if i deploy the application directly through the glassfish admin console using the war file it works perfectly fine but if i try to publish it through eclipse, it gives me unresolved compilation errors
Eclipse did not import ALL glassfish jars, so you need to:
Right Click on the project name, Build Path, Configure build path, under Libraries Click Add External Jars, go to where you have extracted Glassfish and import all jars that exists in:
glassfish4\glassfish\modules
and all sub directories two, like endoresed.
This will fix the problem for CDI and other stuff lik JAX-RS
If I had to guess, your .project and .classpath files are pointing to JAR locations that are specific to your old computer.
This is why people like build tools such as maven, or gradle, you can pick up and reimport a project; it'll resolve all dependencies for you.
Do you happen to use the GlassFish Tools plugin for Eclipse? I found that the GlassFish System Libraries classpath container, which is created implicitly by that plugin and which is added to all projects that specify a GlassFish server as their runtime, misses cdi-api.jar. This is where the javax.enterprise.context.* package is located (and many others).
So I could fix this by adding cdi-api.jar as an External Jar to the build path. After that, you may get a warning like Classpath entry [...]/cdi-api.jar will not be exported or published. Runtime ClassNotFoundExceptions may result., which can be eliminated by using the Quick Fix to Exclude the associated raw classpath entry from the set of potential publish/export dependencies. That JAR file is already contained in the modules folder of GlassFish, obviously.
Maybe this problem only occurs with the GlassFish Web Profile, at least that's what I use.
I am getting the following error:
java.lang.NoSuchMethodError: org.apache.commons.fileupload.servlet.ServletFileUpload.getItemIterator(Ljavax/servlet/http/HttpServletRequest;)Lorg/apache/commons/fileupload/FileItemIterator
though I have added commons-io 1.2 jar and commons-Fileupload 1.2.1 jar in my buildpath.
Please help me out.
There is probably an incompatibility between the file-upload version you're using and the servlet.jar you have on your server.
I can't tell you if it is between the "commons" jars or between the server jars and "commons".
Anyway, I suggest you use a maven (or gradle even better) project at least to get your jars in a consistent way. If your project is not ready, you can still pack your application as a war and get the correct jars from the zipped output fil of your maven compiling.
Short version: I would like to deploy Maven generated WAR to Local Tomcat server and not to build the war with internal IDEA process since the produced WAR file is not the same as the Maven generated one.
Long version: I have been using the Netbeans IDE for my Maven Java project. One of the modules is packaged as a WAR and should be deployed to tomcat server.
In Netbeans when I selected "Run" on the Web Module it asks for application server configuration then it runs the maven 'package' goal and deploys the application(generated WAR) to the Tomcat Server probably via Tomcat manager. So far so good.
We are now in the process of switching to Scala language. Scala classes extend old Java classes and the project is now "Mixed". I have configured Maven to compile the project as a mix of scala and java code. Maven produces a WAR which can then be deployed to Tomcat server without trouble - everything works as it should.
Now I would like to switch to Intellij-idea 12 IDE. But I have a problem: IDEA is refusing to deploy Maven created artifacts and insists of building one by it's own. The war is not the same and can't be used. Is there a way to tell IDEA to use Maven generated WARs and not try to make it's own ?
Just for the record I have already read these articles:
http://riddhimandas.com/blog/111
http://www.jetbrains.com/idea/webhelp/configuring-web-application-deployment.html Manually build WAR by IDEA - Want the maven generated one
IntelliJ IDEA: Maven, project compilation and deployment There is a hint here that IDEA can deploy Maven artifact from the 'target' directory but there is no information on how to do that.
With the help of CrazyCoder I figured it out.
You can make Intellij-Idea to upload your war by selecting External Source
But that's not all, even if you have a context.xml file difining your Context Root inside your WAR file: http://docs.oracle.com/javaee/1.4/tutorial/doc/WebApp3.html
You must specify one for every artifact you deploying (Unless someone will correct me)
The before launch section can be used to tell Idea what to Maven Goal to Run if any
I got the error NoClassDefFoundError when trying to deploy the EJBCA API in my JSF project. When I deploy it in a simple java project, all goes fine with simple classes and JARs imported in the Java Build Path, but in the JSF that not happens.
I tried to copy the jars that I want from EJBCA folder and put in MyProject\WebContent\WEB-INF\lib and nothing happened.
What must I do?
