Hi Muzammel,
this looks like CSCsa88957.
Sun JVM by default doesn't allow access to system clipboard. Java.policy file needs to modified in order to get this access.
After you installed the MSJVM did you go to the internet option in IE
and change the settings to use the MSJVM, check the 3 boxes for
Microsoft VM; Java console enabled (requires restart), Java logging
enabled, and JIT compiler for virtual machine enabled (requires
restart). Also uncheck the Java (Sun), Use JRE for
(requires restart) as a workaround.
Or you get SR5 it will have the fix for the DDTS.
Regards,
Riccardo
