Hi,
Thanks for the Reply..
Can you please let me know how to work with arrays, I tried working with
arrays before going to java.util.Collection.
I could not succeed.
Possibly If I can get a sample work around to return arrays, I would be
thankful to you.
and also let me know if future versions of JAX RPC going to support Java Non
Builtin types like Collection etc.,
Srinivas.

Subject: Re: Need help...Added some Info
IIRC, JAX-RPC DII does not support collections.
For interoperability reasons, it's a really bad idea to expose collections
through a web services interface. You should convert your collections to
arrays. You should also switch to document/literal.

Hi,
I want to add something to my earlier mail here that
Following clients are working fine and I am able to see the output
1.Test client from Weblogic admin console
2.Stub Client app using the stubs generated as part of client jar
3.SOAP client app created using JAXM API
I have problem working with JAX RPC Dynamic Client while getting
java.util.Collection at client side.
Please let me know how to fix this.
