Hi, regarding your first question, is it possible to configure TEWS to be compliant with the WS-I standard. From CA doc:
Programming Guides › Programming Guide for Java › Task Execution Web Service › Web Service Configuration › Web Services Properties Screen
....
Generate WSDL in WS-I form (Note: your existing TEWS code may need to be modified.)
When selected, specifies that the WSDL file is written compliant with the WS-I standard. By default, this setting is not enabled.
Note: None of the TEWS sample applications use this format.
....
Hope it helps, Roberto
