Getting debug output from utl_dbws PLSQL package

When calling web services from an oracle database you can use utl_dbws package. There are times though that you need to debug it to determine why it may be failing. This can be achieved as follows.

call dbms_java.set_output(100000);

Example output from a SQL file as follows. This example is calling a JAXRPC 1.4 web service from OAS 10.1.3.4

SQL:

set serveroutput on

call dbms_java.set_output(100000);

-- call web service methods here now for end point below
-- http://beast.au.oracle.com:7777/wsrocks/DemoWSSoapHttpPort
-- WSDL = http://beast.au.oracle.com:7777/wsrocks/DemoWSSoapHttpPort?WSDL
