Create web service in oracle 10g r2

Question

Hi guys, I am trying to expose a package function as a web service in the database (10g r2) for outside clients to call on. I saw a good example on the following url in 11g http://www.oracle-base.com/articles/11g/NativeOracleXmlDbWebServices_11gR1.php in which you use the dbms_xdb package to configure a port and servlet for accessing the function in the db. However, the 10g r2 version of the dbms_xdb package does not have some of the functions in the 11g version. Eg. dbms_xdb.addservlet, deleteservlet, etc.
How can i go about doing this (without using Jdeveloper)? Jdeveloper creates the web service but the uses your localhost and web logic port in the generated wsdl. I would like something similar to the example above. Can somebody provide an example that works in 10g or point me towards some article that explains how to accomplish this?
Any help is appreciated!
Thanks

If the intention is merely to web enable that procedure, allowing it to be called directly via http, then it can be done 10g using XDB.
XDB supports WebDAV and has a mod_plsql (PL/SQL module interface for web servers) servlet. You configure the Oracle Listener to accept http connections on port 8080 for example and hand it over to this mod_plsql module in XDB. In XDB you configure the behaviour of (and URL signatures supported by) this module.
Note that this deals merely with the connectivity and interface (http to PL/SQL) side - whether that procedure exposes a web services (and returns XML) or whether it returns images or html or text is immaterial from a connectivity viewpoint.
