Answer 1

you might need some more privileges to interact with the system from inside oracle.
I don't know what those are but I had to give privs to a user to open a socket from java.
exec dbms_java.grant_permission( 'MIS_ADMIN', 'SYS:java.net.SocketPermission', 'localhost', 'resolve' ) ;
This allowed the jsp to use localhost. You might need to find a similar permission to grant.
