不建议使用weblogic.ejbc编译器：WebLogic 12c中的EJB应用程序部署

Question

I'm using EJB 2.1, jdk 1.6 with Weblogic 11g for application development. Latest I have been process of deploying application in WebLogic 12c.

As I understood from online source, I need to have jdk 1.7 and higher to run application in weblogic 12c. I also getting below error, when I compile EJB 2.1 with JDK 1.7 or higher.

DEPRECATED: The weblogic.ejbc compiler is deprecated and will be removed in a future version of WebLogic Server.  Please use weblogic.appc instead.

Is it possible to compile EJB 2.1 with JDK 1.6 or least version through deprecated way?

Answer 1

we are using ejb 3.0 compiled on jdk1.6 and deployed on weblogic 12c jdk 1.7.We have not faced any issue like this.It is working perfectly fine.I think you will require to do changes in your deployment descriptor. You can try using descriptors defined in weblogic documentation. https://docs.oracle.com/cd/E13222_01/wls/docs103/ejb/DDreference-ejb-jar.html
