Fetching Groups in the INFOENGINE_COLLECTION from the SOAP Request
The example below illustrates how the Groups can be fetched from INFOENGINE_COLLECTION

//All groups within the input collection are placed in the VDB so that they can be used by the task
//TECHNIQUE01: get all the groups in the VDB and print their names.
for ( Enumeration groups = getVdb().getGroups(); groups.hasMoreElements(); )

String grp_name=((IeGroup)groups.nextElement()).getName();

//TECHNIQUE02: The task author is expected to know the names of the groups.
//So here, query for the input group directly.

}else{
