I've just moved from 11.1.0.5 to 11.1.0.6, and updated my post First Tests of 11g Native Web Services in a few areas:

• The XDB_* role names have been corrected in 11.1.0.6 to match the documentation.
• Confirmed that the auto-generated WSDL still assumes 'orawsv' as the URL pattern (see below). So for now, it's clear that you should stick with 'orawsv' as the servlet name and URL pattern for your native web services configuration.

Thanks to Marco Gralike and Christopher Burke for the chats we've had in the comments thread. Here's a summary of the links that came up in discussion:

• Oracle 11g - How to enable native WSDL services
• Oracle 11g Security - XMLDB is here to stay...
• Mark Drake's example in the forums
