Essential JARs For using BPEL API

The very first jar required is orabpel.jar .In absence of which the java code won’t compile.Now while trying to run the code below error may occur.

Exception in thread "main" java.lang.NoClassDefFoundError: javax/ejb/EJBException

at com.oracle.bpel.client.util.ExceptionUtils.handleServerException(ExceptionUtils.java:76)

at InvokeBPELProcess.InvokeBPELProcessBPELDelegator.main(InvokeBPELProcessBPELDelegator.java:39)

222Process exited with exit code 1.

To resolve this ejb.jar has to be added in class path.

Next error which may occur will look like below:

To resolve this orabpel-common.jar has to be added in class path.

Next error which may occur will look like below:
