I have developed an entity bean called "CustomerBean" with "CustomerHomeRemote" and "CustomerRemote" home and remote interfaces respectively. I put their fully-qualified path in the "ejb-jar.xml" and "jboss.xml" but getting the following error at the time of deployment:
Bean: CustomerEJB
Section: 22.2
Warning: The Bean Provider must specify the fully-qualified name of the Java class that implements the enterprise bean's business methods in the <ejb-class> element.
Info: Class not found: com.titan.customer.CustomerBean
I have checked the typo for class names and their package path. Any idea, why I am getting this error?
Thanks!

It may help us to help you if you post your *.xml files (or the relevant parts of them).

I had a similar problem, perhaps this would help you :

force ANT to recompile your sources, by changing their timestamp, for instance adding a "touch" in your compile target :
<touch>
<fileset dir= "${src.dir}/com/titan/customer" />
</touch>

Best regards. Gerarld.

If your package path overlaps where you created the jar file you will get this exact error. If the path where you created the jar file is in directory /a/b and your code is in directory /a/b/c/d and the package in your java files and ejb-jar.xml is b.c.d instead of c.d you will get this error. (Note: I had to delete the class files before re-compiling to get it to work)
 
It is sorta covered in the JavaRanch Style Guide.
