Sun Java ORB Issue trying to communicate Tuxedo 9.1 ORB

Question

Hi,
I am trying to communocate with the Tuxedo ORB 9.1
The Location which we had mentioned in one of the configuration file whihc read in our code is
ServerLocation = //hpdnt88c:31990
In the Client Code, I am trying to initialize the ORB where I am getting the exception:
"can't instantiate default ORB implementation com.sun.CORBA.iiop.ORB vmcid: 0x0 minor code: 0 completed: No"
The Code snippet is as given below:
Properties p = new Properties();
p.put( "org.omg.CORBA.ORBClass", "com.sun.CORBA.iiop.ORB" );
p.put( "org.omg.CORBA.ORBSingleton","com.sun.CORBA.idl.ORBSingleton" );
Config cfg = Config.getConfiguration();
String serverLoc = cfg.getConfigItem( "ServerLocation" );
if( serverLoc == null )
serverLoc = "";
else
//get the host and port to hit the CORBA server ISL
String host,port;
int idx1 = serverLoc.indexOf("//");
int idx2 = serverLoc.indexOf(":");
int length = serverLoc.length();
host = serverLoc.substring(idx1+2,idx2);
port = serverLoc.substring(idx2+1,length);
System.out.println("Host="+host+", Port="+port);
p.put("org.omg.CORBA.ORBInitialPort", port);
p.put("org.omg.CORBA.ORBInitialHost", host);
String arg0 = new String( "WLEClient" );
String[] args = new String[1];
args[0] = arg0;
_wleorb = ORB.init( args, p );
I have included the rt.jar in CLASSPATH still I am getting the given exception. Any idea why the ORB Init fails?

Try increasing the Xms and Xmx for the server instance.
For JBOSS, if I set the JAVA_OPTS to:
-XX:PermSize=128M -XX:MaxPermSize=256M -ms1280M -mx1280M
it works for me.
