Hi:

I am using MyEclipse 5.1 and Weblogic 8.1. I tried to deploy an enterprise application(an ejb application) and I get the following error:

Try and remove the deployment and re-deploy it as a packaged deployment.

Also if you check your project properties for each project that is part of the EAR, make sure you have Java 1.4 compliance set for the compiler, if you have Java 5 or higher, it won’t work.

Have you tried to remove your existing deployment and re-deploy as a packaged deployment? Can you copy and paste your installation details here? You can get it from MyEclipse > Installation Summary > Installation Details. Can you attach a screen shot of your preferences and deployment. Also what is the exact error you are getting? Can you copy and paste the same from your log file. You log file is located at [your workspace dir]/.metadata/.log
