Unable to create Interceptors | Unable to compile Java services

Hi, I am trying to create some interceptors in our lab whose purpose is to execute pre and post processing service. In the background some java services like getInterceptors are being run but I am getting an error:

“Service ‘wx.interceptor.pub.config:getInterceptors’ is not operational. To run this service, first recompile the Java source.”

When I tried to compile the package using – sh jcode.sh makeall command I got a different error as:

Unable to locate or start the compiler

Although in our server we already have defined path for javac in extended settings as well as in server.cnf:

watt.server.compile=/opt/softwareag/jvm/jvm/bin/javac -classpath {0} -d {1} {2}
watt.server.compile.unicode=javac -encoding Unicode -classpath {0} -d {1} {2}

Could anyone please help me to understand the real root cause and the resolution to resolve the issue. Please let me know if you need any further details
