Eran Chinthaka commented on AXIS2-1061:
---------------------------------------
1. I didn't say if u use the same callback the invocations are synchronous.
Please read carefully what I've mentioned. What I was trying to say is that,
if you invoke using one callback and if you are continuously checking
callback.isComplete() == true, and then you invoke the second one, then only
you are wasting the power of non-blocking invocations. Non-blocking invocations
are such that you can invoke multiple times, independent of each other.
2. Its not a matter of you waiting for sometime. Its a matter of OM object tree.
Just try this code to understand more.
<code>
1.OMElement payload payload = getTestOMElement();
2.
3.OMFactory fac = OMAbstractFactory.getOMFactory();
4.OMElement parentOne = fac.createOMElement("ParentOne", null);
5.OMElement parentTwo = fac.createOMElement("ParentTwo", null);
6.
7.parentOne.addChild(payload);
8.parentTwo.addChild(payload);
9.
10.System.out.println(parentOne);
11.System.out.println(parentTwo);
</code>
What can you see?
Then replace line #8 with the following and run the code.
parentTwo.addChild(parentTwo.cloneElement());
What can you see? Can you explain it?
Its the same thing that happens during your invocations.

> Project: Apache Axis 2.0 (Axis2)
> Issue Type: Bug
> Components: client-api
> Environment: Windows XP sp2, jdk 1.5.03, mac os X 10.4.7, jdk 1.5_06,

> Reporter: Michele Mazzucco
> Priority: Critical

> The call sendReceiveNonBlocking call fails when multiple, identical messages
> are sent. More in detail, the first send succeeds, but the second fails
> because the message is sent with an empty SOAP body. A workaround is to
> interleave two consecutive send operations by (at least) 600 ms (on my
> system).
> In other words:
> for (int i = 0; i < execution.requestNum; i++) {
> OMElement payload = getTestOMElement();
> sender.sendReceiveNonBlocking(payload, callback);
> }
> succeeds, while:
> OMElement payload payload = getTestOMElement();
> for (int i = 0; i < execution.requestNum; i++) {
> sender.sendReceiveNonBlocking(payload, callback);
> }
> fails, because (from the second send) the SOAP message is empty
