Hi,

Currently My application has ejb 2.0 and web 2.5. we want to use ejb 3.0 with ejb 2.0 module. I mean, we do not want to create a separate module for ejb 3.0. Already existing ejb 2.0 module we want to use. i hav written a sample application. When deployed ejb 3.0 is not recognizing. ejb 2.0 is working fine. Please tell me whether we can use ejb 3.0 in the ejb 2.0 module

Thanks
Vipul

Hi vipul,
Your question is quite confusing. I think you need to use the right terms.

Note that, the ear which will have both the jar and the war file will have a version which would be 1.4 in your case. You can find this from the application.xml file.

So, when you are upgrading, the JEE version will be 5 or 6 - so your ear will be like 5 or 6 - lets say 5. This would mean you can use EJB 3.0 and I think servlet will continue to be 2.5
So, when you deploy a JEE 5 application, you can continue to use ejb 2.0 as the severs generally support older versions.

What is the error you are getting? what is the server you are deploying against?
