Calling wsadmin scripts from ant

You can simply add the following to a target.
For the following wsadmin should be in your PATH env.

< exec dir="." executable="wsadmin.bat" logError="true" failonerror="true" output="wsconfig.out" >
< arg line="-lang jython -f ../../createQFactory.py"/ >
< /exec >

All output will be logged to wsconfig.out

Generate XML – DBMS_XMLGEN

On my way to my solution store just found this nice to use, old and easy feature.
Possibilities endless, usage typically very easy.

I used the following to generate XML from sqlplus:

 select dbms_xmlgen.getxml('select * from user') from dual; 

Output:

< ROWSET >
 < ROW >
  < TNAME >Employee< / TNAME >
  < TABTYPE > TABLE < / TABTYPE >
 < / ROW >
< / ROWSET >
