javascript client and generic types
Hi everybody,
I managed to get a javascript client example working but it barfs
in some cases.
All my server classes are pojos and I am using the simple frontend (I think)
with Aegis. I am very pleased with java2java communication since I can
pass complex types with no annotations at all.
The problematic cases are of the form. (All other cases are working with js client)
public interface Service<T, P> {
public int open(P args);
public void close(int handle);
public int getValue(int handle);
}
My guess is it barfs in the generic P type argument.
When I am trying to do http://localhost/ws/SomeService?js
tomcat produces an error
Do I need annotation of some kind, jax-ws or something?

Hi Benson,
First of all thanks for your quick reply

I filed a jira. It can be found at
https://issues.apache.org/jira/browse/CXF-1758
If there is a problem let me know.
Do you think that this behavior is fixable?
I mean what will happen if I call open(P arg) from
javascript? What if P is
1) an integer
2) a string
3) an object
4) an array of strings
5) an array of objects
what types I will receive at the other end?
My guess that is difficult to solve without extra information. However I am not a guru and I certainly hope to be wrong in this case since that would be a very valuable feature...

Please file a Jira. I didn't think about this case when I did the
Javascript code, and this will take some work.
