Re: Attachment upload Client to Server, use Handlers?

[Stefan Schuster <ss...@pironet-ndh.com>]

Hi Alexandre,

I already got the server-side working. The problem is that
a client fails to get the messageContext bevore the first call.
I wonder if I can use handlers on the client and how
to configure them?

BTW. Thanks for the suggestion, it almost helped :-)

Re: Attachment upload Client to Server, use Handlers?

The client uses Axis. My problem is that in the client, I cannot
get an Message context before the first call to the server through the
stubs. The trace shows a simple NullPointerException in my client.
