Tips for migrating thin application client code:
The Java invocation used to run non-J2EE application clients has changed in Version 5.0. You must specify -Xbootclasspath/p:%WAS_BOOTCLASSPATH% on Windows systems or -Xbootclasspath/p:$WAS_BOOTCLASSPATH on UNIX systems when you invoke the Java command.

install_root\samples\bin\ActiveXBridgeClients\VB\XJBExamples\modXJBHelpers.bas
