My both project's implemented class are Stateless Session Bean Class.

Hi,
I think you deal with a deployment exception.
Here are my tips : build a ear that contains both your projects, each project is a ejb-jar. Each ejb-jar must use @local/remote and @statefull/stateless or the equivalents in the deployment descriptor (ejb-jar.xml).
If it fails please post your ear structure.

Regards,
Mihai

Hi Mihai Thanks a lot for reply but will you tell me how to make ear for both Project and deployment descriptor(ejb-jar.xml).I am new to EJb and i am using EJB3.0.

Thanks a lot for your kind help

Hi

Ear is the top level archive for the enterprise application. If you have time you may consult the chapter 20 - named "EJB-jar File" from the specifications (JSR220).
The build methodology for this archive may depending on the underlying tools (IDE, maven, gradle, ant, etc) but the archive structure remains the same. In your case you need something like :
my.ear:

project1-ejb.jar

project1-ejb.jar

After your log file I presume that you use netbeans so go in File->New project->Enterprise application. After you are ready with this select the fresh create enterprise application do right click choose "Add new module".


Regards,
Mihai.

Once again Very Much thankful to you Mihai.
I am using Eclipse IDE and dont have any building tools like Ant or Maven.I am new to this technology so facing problem.
