Java/COBOL and J2EE Interworking

J2EE Resource Adapters

When you undeploy a resource adapter from BEA WebLogic 8.1 or BEA WebLogic 9.0, you receive a java.lang.NullPointer exception. This does not cause any problems and will be investigated in future.

Java/COBOL Interworking

On HP-UX on Itanium 64-bit, if you use Java 1.4.2 , you might experience a problem with initializing the Java environment that can manifest itself in various ways. Setting the environment variable COBMAINSTACK to 512000 or greater might resolve this:

COBMAINSTACK=512000      
export COBMAINSTACK

J2SE 1.5.0 / COBOL Interworking

On Linux, to avoid fatal errors in the Java VM, do not install both 32-bit and 64-bit JDKs into the same base directory.

J2EE Resource Adapters

On Solaris using Oracle 10.1.2, a NullPointerException is sometimes thrown at the end of a session. You can avoid this by catching the exception and moving on to the next operation. The result of executing the COBOL program is available in your output.
