[Axis2] multiple requests question
Hi all,
is it possible to send multiple request with the same
ServiceClient/OperationClient? If yes, could anybody explain me why I'm
getting a NullPointerException when multiple requests are issued with
the same sender object (please see the stack trace below)? I'm using the
latest nightly build and, if I'm right, I remember the same code worked
successfully some time ago. Any idea?
Thanks,
Michele

Posted by Michele Mazzucco <Mi...@ncl.ac.uk>.
Hi all,
I've partially fixed the problem by changing the call:
sender.sendReceiveNonBlocking(payload, callback)
with
sender.sendReceiveNonBlocking(getPayload(), callback);
I've also tried to add the property
options.setProperty(HTTPConstants.REUSE_HTTP_CLIENT, Boolean.TRUE);
as described here (http://www.wso2.net/kb/87)
but in that case some messages (for some obscure reason) are not delivered.
