Data Federator - Read timed out

Question

Hi,
I'm using Data Federator XI 3.0 SP2. I have a datasource connecting to a web service. The web service may return take a long time to do heavy processing, etc., before returning any data. If I call the web service via Data Federator, I will get the following error
Exception was thrown while executing a query on Data Federator Query Server.
  An exception occurred when querying Data Federator Query Server.
    [Data Federator Driver][Server]
[Wrapper /TEST/sysadmin/sources/draft/ReturnInputAsOutput]HTTP input/output exception: Read timed out
      [Wrapper /TEST/sysadmin/sources/draft/ReturnInputAsOutput]HTTP input/output exception: Read timed out
        [Wrapper /TEST/sysadmin/sources/draft/ReturnInputAsOutput]HTTP input/output exception: Read timed out
          HTTP input/output exception: Read timed out
I'm guessing that the Data Federator query timed out because the web service takes a long time to response, is it not? If this is the case, how do I increase timeout value? If this is not the case, then what does the error mean and how do I resolve it?
Thanks.

Hi Dayanand,
For testing purpose, I created a small simple web service with only one operation that sleep for more than two minutes before returning a string. I called this web service operation from Data Federator. After waiting for a while, I got the "Read timed out" error
