Hi Anil,
Are you sure it keeps requesting to install Java Web Start or that it could not launch Java Web Start ?
If the message says "JAR resources in JNLP file are not signed by same
certificate", please take a look at note #1598282 and apply the
mentioned patches then check if this issue could be resolved.
If not, please send me a screenshot of the details.
If Java Web Start has been installed, you will be able to launch the
ESR/Directory on the WTS server. If not, you won't be able to launch it.
You should also be able to view if it is installed in Start -> All
Programs. See the note below for further details on it.
