Ok, I think the problem is in the rt.jar file.  The beginning of the
error is as follows:

# /opt/sun-j2ee-1.3.1/bin/j2ee -verbose
J2EE server listen port: 1050
Exception in thread "main" java.lang.NoClassDefFoundError:
com/sun/corba/se/internal/util/IdentityHashtable

However, the following command shows the IdentityHashtable in a
different location.

# jar tf /opt/sun-jdk-1.6.0.18/jre/lib/rt.jar | grep "IdentityHashtable"
com/sun/corba/se/impl/util/IdentityHashtable.class
com/sun/corba/se/impl/util/IdentityHashtableEntry.class
com/sun/corba/se/impl/util/IdentityHashtableEnumerator.class


I think the difference is j2ee is looking for "IdentityHashtable" in
com/sun/corba/se/internal/util/IdentityHashtable but the jar file has it
in com/sun/corba/se/impl/util/IdentityHashtable.class .

Is this the problem?  If so haw can it be fixed?

Thanks,
