When I search google with string "tsm java.security.Accesscontrolexception"
(I removed one l from controll) I get some hits that might help

Betreff: [ADSM-L] 5.4.1.x BA WEB GUI JAVA errors


Hi 
 
We are experiencing problems with upgrading clients from 5.3 to 5.4, every 
client upgraded so far has broken the WEB GUI, with all clients using IE6 
reporting the following error message
 
ANS2603S Browser trying to establish connection to client; received 
exception:java.security.AccessControllException: access denied.
(java.net.SocketPermission 10.10.200.100:1055 connect resolve
 
If we downgrade back to 5.3, it works again !!
 
Looking on IBM's website reveals a Java permissions setting in the 
Java.profile, but this is set on all the clients that I have used to connect to 
the server. (IE6)
 
Tivoli Support have currently gone quiet, so I assume they have not come across 
this before
 
Thanks
Phil
