Could not invoke Java compiler, please make sure jikesw

[Raghavendra Porumamilla]

we are running the application on Jrun for many years and suddenly we see the following error. Can anybody tell us what would be the problem?

07/22 12:02:06 error Could not invoke Java compiler, please make sure jikesw is in /usr/jrun4/bin or put a JDK bin directory in your path.
jrunx.compiler.JavaCompiler$NoCompilerFoundException: Could not invoke Java compiler, please make sure jikesw is in /usr/jrun4/bin or put a JDK bin directory in your path.
