"Starting hsqldb database manager from the jmx console with jboss 6.0"

--------------------------------------------------------------
While using a database server login module for authentication in jboss 6, I 
found it very useful managing principals and roles with the hsqldb database 
manager gui. This can be invoked via the JMX console. There are no problems at 
all when the application server resides on the same machine from which I'm 
using the JMX console.
Now I'm in the situation in which the application server runs on a different 
machine, say a linux box to which I connect via ssh, +tail -f+ the logs for 
debugging and stuff, and I develop on a machine with a plain Vista installation.
Of course the JMX console is still accessible, but this time I can't manage to 
have the hsqldb database manager window showing up.
I installed the classic XMing X server without any special configuration (I'm 
not very well versed in X servers, so I'm practically using the default 
settings), and all that I found was the need to set and export the DISPLAY 
environment variable on the remote machine so that it points to the development 
machine, as in:
 set DISPLAY=192.168.0.5:0
 export DISPLAY

I also configured my ssh client (the simple putty) for X11 forwarding to the 
same ip address the remote DISPLAY variable points to.
Now when I try invoking the database manager from the JMX console, I get this 
exception trace:
{code:java}
