Description of problem:
Trying to create a liferay consumer for JPP 6.2, but when entering the producer wsdl url (provided by JBoss Portal interface) in the liferay consumer setup it always says url does not point to a valid wsrp producer. 

Version-Release number of selected component (if applicable):
JPP 6.2 + Liferay 6.2 CE

How reproducible:
always

Steps to Reproduce:
1. Start JPP 6.2
2. Start Liferay 6.2 CE + WSRP CE portlet
3. In Liferay, go to Control Panel -> Apps -> WSRP
4. Click Add Consumer
5. Enter Name and URL field (using JPP 6.2 producer URL)

Actual results:
Registration fails with the following error on the JPP producer side:

Expected results:
Registration is successful

Additional info:
Starting the producer with -Dorg.apache.cxf.logging.enabled=true shows the following request coming from Liferay:

Note that a <wsse:Username> eleement is present in the request, but no <wsse:Password> element.

Note also that this failure shows up even if the user (here: test) is present in the JPP 6.2 producer instance.
