: Entity Beans are no longer supported

Question

I am using wildfly 10.0.x. And I am migrating ejb2.1 to ejb3.2 so this is my ejb-jar.xml file

But I cannot deploy this ejb to server.

How can I fix it?

Answer 1

There is no way to just change some properties/xml configuration and redeploy your current CMPs into a new JavaEE application servers. You must make some changes in your code and recompile them.

Regarding its complexity, it's mainly depends on the way you used CMPs and the level of abstraction you have on top of your persistence layer. You may need to do some refactoring/restructuring on your beans.

I highly suggest taking a look into the following guide so that you would have a better idea about required/optional changes you should made to migrate your application to JPA.
