any helpDon't use Java when PL/SQL is perfectly capable of doing the task at hand?
I have an inherent dislike of systems and application that have too many moving parts. Keep the moving parts to a minimum.. and the code is faster, more robust, and a lot easier to read, understand and maintain.
So in that regard, I do not understand what the deal is with utl_dbws and why it could not just use plain vanilla PL/SQL..? But then there are likely Java faithful that proclaims The Religion too when designing PL/SQL interface packages in Oracle... :-(
I've posted an example of how to call a web service using PL/SQL code only, no Java, in {message:id=4205205}.
