Worklist taskExecute Permission AccessException

Question

Hi.
I am using WLI on WebLogic Server 7.0 /NT.
I get an Insufficient Permission exception when attempting to invokde worklist.taskExecute()
from a WebApp running within an EAR in WebLogic.
Strangely enough worklist.taskExecute() works fine from a remote client.
Any suggestions?
The attached file is the stack trace.
The code below is my class delegating calls to the worklist:

I've written my own worklist application in Swing. I'm using WLI 2.0 and Solaris
2.8.
Unfortunately, I have to set my DISPLAY variable on the server before running
the startmydomain.sh script. This is bad, because I can't keep the server process
running in the background (after I log off). But if I DON'T set the DISPLAY,
I get the following error when I run my client application:[snip]
Dave,
I have that exact problem right here - except I don't seem to be able to
fix
it by setting the DISPLAY variable(?).
If I use DISPLAY=localhost:0.0 I start the server, it doesn't change a
thing.
However, if it works for you, you should still be able to start the
server,
and then logoff. What if you did -
"DISPLAY=yourhost:0.0 nohup ./startmydomain.sh & " - wouldn't that solve
your problem ?
