title: Compilation failed for ejb
body: <p>I'm struggling with this problem. It was working for me before, and suddenly when I did some changes in my interfaces and implementation class and when I try to build, I'm getting the following error. I tried uninstalling weblogic, jdk, everything. But still I have this problem. Please help me.. I'm using weblogic10.0 , jdk1.5.0_22, jre105.0_22, Eclipse indigo</p>
