Hello,
If someone familiar with creating service clients with AXIOM, please help!
I was checked for outgoing SOAP messages with http sniffer on client
requests to server and realized that some of them is malformed by
interleaving each other why other is empty. Sometimes they become so twisted
that even result = sender.sendReceive(method); can't pass XML structure
analyze phase and can't do the request at all - exceptions thrown is very
varied then, but all of them indicates broken XML structure. How can this
happen?
I didn't use any static objects in my code which can assign to the same
static variables and i checked content of outgoing OMElement - it's always
well-formed. Problem happen inside sendReceive method.
I suppose sendReceive method of sender object sometimes write to same
httpclient stream. How i can
avoid such interleaving?
Example of such broken request:
1 thread: <??xmxlml ..... (and so on)
while
2 thread is empty
but
3 thread's request is properly formed and passed
ServiceClient sender = new ServiceClient();
sender.setOptions(options);
result = sender.sendReceive(method);
very sorry for bad english.
With hope,
Daniil
