I have deployed the same web services in two machines.
I have used Microsoft Web services extensions.
The web service has a method Search.
When there is no return type defined for the method it works on both
the machines.
When a return type is defined for the method. It fails in one machine
but works fine in the other machine.
I am giving below the error message and stack trace.

The error message:
The XML declaration is unexpected. Line 11, position 191.
