SendEsbMessage Error

vishal12345 Aug 15, 2008 7:38 AM

Using following code to sed esb message in HelloWorld example

Message esbMessage = MessageFactory.getInstance().getMessage();
ServiceInvoker i = new ServiceInvoker(args[0],args[1]);
System.out.println("Created invoker");
esbMessage.getBody().add(args[2]);
i.deliverAsync(esbMessage);

and i m getting following error

[echo] Runs Test ESB Message Sender

Take a look at one of the SendEsbMessage classes in quickstarts. For example in the helloworld quickstart:

public static void main(String args[]) throws Exception
 {
// Setting the ConnectionFactory such that it will use scout
 System.setProperty("javax.xml.registry.ConnectionFactoryClass","org.apache.ws.scout.registry.ConnectionFactoryImpl");

 if (args.length < 3)
 {
 System.out.println("Usage SendEsbMessage <category> <name> <text to send>");
 }

 Message esbMessage = MessageFactory.getInstance().getMessage();

 esbMessage.getBody().add(args[2]);

 new ServiceInvoker(args[0], args[1]).deliverAsync(esbMessage);

 }

See the comment about scout and see if that works for you.

k that worked finally i have a doubt this is probably my missunderstanding but i want to confirm

following is the code which is suppose to place n messages on ESB
i want the listener to get invoked n times but it gets invoked very oddly
this loop currently goes three times but all three messages appear in only one message body when recvd by listener what shud i do to change it to three different messages , please help

for(Request thisreq: req){
System.out.println("New Message");
//System.out.println(thisreq.print_Messages());
Message esbMessage = MessageFactory.getInstance().getMessage();
esbMessage.getBody().add(thisreq.print_Messages());
new ServiceInvoker("TSService","TsListener").deliverAsync(esbMessage);

//sjm.sendAMessage(thisreq.print_Messages());
}
