I understand the container is unable to find the jar file.. But I have necessary jar files in ORACLE_HOME/J2ee/home.../applib directory.
I still get the same error.I have the necessary jar files in web-inf/lib directory in the Ear file.
I checked java versions and OAS jdk version they are pretty similar..Is it anything to do with system variables, classpath?.

I tried them too.. Please advise

I am trying this on Windows OS. Am I missing something?.
