Java, JMX, WebLogic and DomainRuntime

I try to run the code:

http://docs.oracle.com/cd/E12840_01/wls/docs103/jmx/accessWLS.html#wp1111297

I get this error:
java.net.MalformedURLException: Unsupported protocol: t3
I add "C:\Oracle\Middleware\wlserver_10.3\server\lib\wljmxclient.jar" to the classpath

This time I receive a
"org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 211 completed: No" caused by java.io.IOException: End-of-stream at com.sun.corba.se.impl.transport.SocketOrChannelConnectionImpl.readFully(SocketOrChannelConnectionImpl.java:666)

This is apparently an issue in the JVM (see Doc ID 1598451.1 ) ... they say one can add -Dcom.sun.CORBA.connection.ORBHighWaterMark=300 ... personally I give up in frustration.
