Question

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** 
CLASSPATH=/bea/Oracle/Middleware/patch_wls1032/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/bea/Oracle/Middleware/patch_oepe1032/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/bea/Oracle/Middleware/jrockit_160_14_R27.6.5-32/lib/tools.jar:/bea/Oracle/Middleware/utils/config/10.3/config-launch.jar:/bea/Oracle/Middleware/wlserver_10.3/server/lib/weblogic_sp.jar:/bea/Oracle/Middleware/wlserver_10.3/server/lib/weblogic.jar:/bea/Oracle/Middleware/modules/features/weblogic.server.modules_10.3.2.0.jar:/bea/Oracle/Middleware/wlserver_10.3/server/lib/webservices.jar:/bea/Oracle/Middleware/modules/org.apache.ant_1.7.0/lib/ant-all.jar:/bea/Oracle/Middleware/modules/net.sf.antcontrib_1.0.0.0_1-0b2/lib/ant-contrib.jar:

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

Could not find the main class: utils.MulticastTest.  Program will exit.

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 ..

Your environment is actually NOT set. You need to source the script using either source or . (the “dot” command):

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

PATH=...

Your environment has been set.
$ java utils.MulticastTest -n name -a address [-p portnumber] [-t timeout] [-s send] [-l timetolive]
