I am upgrading weblogic from version 12 to 14 and I am facing some issues while doing so. One such issue is related to ejb's. In 12c, the ejb version is 2.1 and in 14c the version is 3.2. Since there are multiple changes in between version 2.x and 3.x, like not requiring the deployment-descriptor, the home interface being removed, etc. With these major changes the local and remote interfaces aren't present in ejb3 which is causing compilation failures while building my application in 14c.
Are there any specific steps to migrate from ejb2 to ejb3 or is there any other workaround to solve my issue?
