Jrockit Oracle' Java seems to work well with Weblogic.

I tried my weblogic.Deployment through sun java which threw nullpointer error.

so i pointed to jrockit java which seems to have worked,

$export JAVA_HOME=/scratch/test/Oracle/sriram/jrockit_160_22_D1.1.1-3/

To check if weblogic.deployer works with below classpath:

 $java -classpath /scratch/aime1/Oracle/sriram/wlserver_10.3/server/lib/weblogic.jar weblogic.Deployer -help
