Troubleshooting org.omg.CORBA.COMM_FAILURE

If you get the error

org.omg.CORBA.COMM_FAILURE: java.io.IOException Peer disconnected socket

when deploying or accessing your business components, one of the following may be the problem:

Your JDeveloper JDBC driver may be a different version from the one on Oracle8i

Replace

<jdeveloper_home>\jdbc\lib\oracle<x>\classes<y>.zipwith

<oracle_home> \jdbc\lib\classes<y>.zip

where <x> is the version of your Oracle database (for example, 8.1.7), and y is the first two numbers in the version of Java you are using, with the dots removed (for example, 12 for Java 1.2._).

Your Java pool size may be too small

Business Components for Java deployed as EJBs work best with a Java pool size of at least 50MB. Edit your init.ora file and check the java_pool_size parameter. If it is under 50MB, change it, restart your database, and try your connection again.
