Not able to execute java utils.MulticastTest in Weblogic 11G

I know this is very basic but i am frustrated like anything.. i googled and tried everything i could. But i am not able to execute this utility.

java utils.MulticastTest 

I am using weblogic 11g on Linux open SUSE. i gotta find it soon as need to replicate on production :

Also i guess (not sure) this utility exists in weblogic.jar i am executing

**linux-0m8r:/bea/Oracle/Middleware/wlserver_10.3/server/bin # ./setWLSEnv.sh**

Your environment has been set.

even after that when i run

$ java utils.MulticastTest -N server100 -A 237.155.155.1

it gives following error:

linux-0m8r:/bea/Oracle/Middleware/jdk160_14_R27.6.5-32/bin # ./java utils.MulticastTest -N server100 -A 237.155.155.1

Also i have two jdk installed first is OS one and one bundled with weblogic. tried with both but not able to run it.. it is purely an classpath issue i can see but i am unable to figure it out how to solve it .. any help will be highly appreciated .. i am availabe for next 12 hours for any questions ..

$ cd Oracle/Middleware/wlserver_10.3/server/bin
$ . ./setWLSEnv.sh
