Hi,
I am using syncproxy tool kit for a testing purpose. It working
perfectly when i deploy my web application in the Eclipse default
server (Jetty). That i could access my remote method from my java
application. But when i deploy the web application in Tomcat5 server,
its failed to access the remote method. Please help me how to resolve
this.
I am getting the following error.

ModuleBaseURL="http://localhost:8080/jax/jax_server/";;
GreetingService server = (GreetingService)
SyncProxy.newProxyInstance(GreetingService.class,
ModuleBaseURL, "greet");
System.out.println(server.greetServer("Anoop John"));//
A method in
interface and crashed here
System.out.println(server.getUpdatedMessage("Buzz"));//
A method in
interface
}
catch (Exception e) {
e.printStackTrace();
}
