Input the data into context in Swing

Hi,

I'm currently working on EJB's Interceptor. Whats a problem now is how can I input the data (say, userID) into the context, at the client side, so that it can be accessed using .getContextData(); ? The client is a Swing application. I don't want the client to be passed to the server side as a parameter.

To make it clear, it's like this

Swing apps
->input userID into context
-------------

V
V

In Server-side
Interceptorclass(InvocationContext ctx){
HashMapObject = (HashMap) ctx.getContextData();
}
-------------

Thanks, a total newbie here.

Hello,

you should explain the problem a little bit more detailed.

You can insert a value in a client interceptor and access it in the server interceptor.

client interceptor:

public Object invoke(Invocation invocation) { HashMap hm = new HashMap(); invocation.setValue("key", hm); }

server interceptor:
public Object invoke(Invocation invocation) { HashMap hm = (HashMap)invocation.getValue("hm"); }

But I guess you have the problem then to get the data from the client-application accessible in the client interceptor. You could do this under some cirumstances with the ThreadLocal functionality.

But I'm not sure if this is your problem.
