Your jbi.xml "says" this:
<br/>+ If the request message has a "add" element as the root element, then invoke MultiService.
<br/>+ Otherwise, invoke SommeService.
<br/><br/>When you send the message that starts with "mul", the test fails and the second service is invoked.
<br/>Since it does not have the "mul" operation, it returns <b>No such operation 'mul'</b>.
<br/><br/>The reason why the "add" works is a little more tricky and it needs to be confirmed.
<br/>In fact, the first test fails too. And the default service (SommeService) is invoked.
<br/>I think the test fails because the request you send does not have qualified elements. And thus, the XPAth function <b>local-name</b> returns an empty string.
<br/><br/>Conclusion: to make it work, change your test to find "mul" elements, and qualify the elements in your request (take a look at the WSDL of services you invoke to find the namespace URI).
