how to confirm JServer is installed in the db

[dbasan]

Gurus,

After doing little bit research I got it.

to verify whether JServer is installed or not :

dba_registry;

and need to run the $ORACLE_HOME/javavm/install/initjvm.sql.
to install the JServer.

I got this from orafaq using google.

Thanks

Can also get it from Oracle universal installer
