Dependencies : Jboss 7

[Vinit Parakh]

I am trying to deploy a war file on jboss 7..but i am getting an error saying Class not found.
I tried goggling it and found that the dependecies in the WAR files have to be explicitly mentioned in the Manifest.mf.
I tried doing that....But still getting the same error....I am not sure as to what is to be specified in the ClassPath and Dependencies.(Since the same war file worked properly when i used it with jboss 4.2)
My war File is basically dependent on one Ejb-Jar file.

What changes do i make in the War file so that It is correctly deployed.
Class-Path :
Dependencies :

I am a newbie to jboss 7.

Any help would be really appreciated.

Thanking you,
Vectors.

I have included the Ejb-jar file in the buildpath.

However if i specify :

Class path : First-Ejb3Tutorial.jar
Dependecies : First-Ejb3Tutorial.jar

I am getting the following error log :

main is not found ???
I didnt get that. My jar file however does not have a main function.

Any help appreciated.

Thank you,

Any one???....I am still stuck at the same point.....how do you resolve dependencies.

[Jaikiran Pai]

Don't add the (module) dependencies for now. Post the ClassNotFoundException exception stacktrace that you see. Also tell us more about how your war is packaged, specifically where exactly in the .war does that class reside?

[Vinit Parakh]

Thanks Jaikiran for replying,

This is my stack trace :

The war file basically contains a servlet which contains a post method - that calls a function(Test) that is defined in the the class of the ejb-jar file.
This thing basically i am trying to check the user name password thats it.

I have successfully deployed the ejb-jar file in standalone/deployment/
and i am trying to deploy the war file at the same place.

I have also included the jar file in the buildpath of the war file.

[Jaikiran Pai]

de/laliluna/library/BookTestBeanLocal

Where's that class located in the .war file?

[Vinit Parakh]

Thanks Jaikiran,

I have that class in the jar file and i import that as " import de.laliluna.library.* ".
And since i have included the jar file in the build path of the project....It was able to use the "test" function from BookTestBeabLocal in the earlier version , that is jboss 4.2...but now it says no class not found.
I feel it should be able to access that class since i have included the jar file (which contains "de/laliuna/library/BookTestBeanLocal").

Thanking you,
Vectors.

Let's keep out the build environment for now. Where exactly is that jar file within the deployed .war file?

[Vinit Parakh]

In libraries of the war file.
This is the tree structure :

Project/JavaResources/Library/FirstEjb3Tutorial.jar

[Vinit Parakh]

Hey Jaikiran ,
Thanks for your reply.

No, I actually meant the final .war that gets deployed. Where in that .war is the jar located. Post the output of:

jar -tf Aurora_android1.war

[Vinit Parakh]

Thanks Jaikiran,

This is what you asked for :

C:\Users\vinit\Desktop\jboss-as-web-7.0.2.Final\jboss-as-web-7.0.2.Final\standal
one\deployments>jar -tf Aurora_android1.war
META-INF/MANIFEST.MF

WEB-INF/classes/com/
WEB-INF/classes/com/aurora_android1/
WEB-INF/classes/com/aurora_android1/TestServlet.class
WEB-INF/lib/
WEB-INF/web.xml

But I dont think the jar file is there in this. But i did it the same way by putting it in the libraries and it worked for me but i dont know...about jboss 7.

[Vinit Parakh]

Hey Jaikiran,

I am still stuck.....What do i do next....??

Thanking you,
Vectors.

[Jaikiran Pai]

So that jar isn't packaged in the .war at all. Where is it placed on the running server then? Deployed separately? Why not package that jar within the .war/lib of the application. If you still want to deploy them separately, then you can do that. But you'll then have to add the dependency via the jboss-deployment-structure.xml (or MANIFEST.MF) to point to the module of the other deployment (ex: deployment.myjar.jar). See this for the full details https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7

Hey Jaikiran,

It worked i was successfully able to deploy the war file and my project is running. I did it by deploying the jar in the web-inf/lib folder. But this is a tedious task, I mean if i make even little changes to the jar file i again have to go there and deploy the jar file. The other method(specifying dependencies in manifest.mf) seems to overcome this problem. I tried doing it through that method my specifying the dependencies in the manifest.mf but i dont know what exactly is to be specified in the class path. I am getting an error if i set the classpath to the jboss deployment folder.

This is the error log :

Hi vinit, could you please share me your META-INF/MANIFEST.MF file.

i would expect your file like :

Manifest-Version: 1.0 
Dependencies: deployment.FirstEjb3Tutorial.jar

And you don't need to add your ejb jar into the lib of web project. Your file structure should resemble as :

C:\Users\vinit\Desktop\jboss-as-web-7.0.2.Final\jboss-as-web-7.0.2.Final\standalone\deployments\Aurora_android1.war
C:\Users\vinit\Desktop\jboss-as-web-7.0.2.Final\jboss-as-web-7.0.2.Final\standalone\deployments\FirstEjb3Tutorial.jar
