Running process integrator studio remotely

Question

Hi again
-I have the following scenario.:
My installation of Process Integrator is on a solaris server. To facilitate using
the Studio application,
I have packaged up the required jar files and am able to run the Process Integrator
Studio Java Application remotely.
When starting the collaborate samples server up on the console and connecting
to it remotely (from my machine) ,
it works fine.
BUT when starting up the server remotely through a telnet session and then connecting
to it using the application from my machine, problems start to appear.
Firstly, the server log reports a very long exception list that starts as follows:
javax.transaction.TransactionRolledbackException: java.lang.InternalError: Can't
connect to X11 window server using '<serverip>:0.0' as the value of the DISPLAY
variable.

at com.bea.wlpi.server.plugin.PluginManagerImpl.getPluginInfo(PluginManagerImpl.java:1315)
as far as i am aware, this problem should not arise, because (from what i can
see) no gui app is started on the server, so X11 connectivity should therefore
not matter. And besides, this problem does not arise when collaborate is stared
on the server console.
Can anyone shed any light on this problem?

Interesting.
As the stacktrace suggests, there is a call to javax.swing.ImageIcon constructor; which
needs some native information related to X11 server. This is the swing behaviour, BEA
can't help it :)
Set your DISPLAY env variable to correct value and after that this should work even
from a telnet session. You will need X11 authorization to connect remotely, though.
BEA can "fix" this by storing icon detail in bytearray instead of ImageIcon object; as the
server side is not going to need ImageIcon object : It just needs to send the information
to client side. Then client side can build ImageIcon using this bytearray. But I guess this
is too much to ask if the workaround above works.
