If you use RTVJOBA to retrieve the CURUSER parameter, you'll get the userid 
the command was submitted with.  QUSER is used as an initial userid, the 
remote process switches to the actual userid (that used to connect to the 
as400 with) dynamicly.

Is weblogic running on the 400?

Make sure you QUSRWRK subsystem is active ... I would actually suggest you 
add some code to make sure your programs are running in QUSRWRK as apposed 
to QSYSWRK.  Unexpected things can happen if you run in QSYSWRK.
