XML Datasource

Question

Hello:
I am trying to change a datasource at runtime using java.  The datasource is an XML file located on the local machine.  The original and new XML datasource are the same format from a tag perspective.
I convert the XML file and pass it to the setDatasource() method of the dbcontroller.
The following exception is then thrown:
Exception caught: com.crystaldecisions.sdk.occa.report.lib.ReportSDKLogonException: Logon failed.
Error in File C:\WINDOWS\TEMP\TRW_Test {6BA2425C-D38F-43BA-B394-0382CA1AF83F}.rpt:
Unable to connect: incorrect log on parameters.---- Error code:-2147217393 Error code name:dbLogonFailed
It appears the RAS is trying to logon to this temporary report or datasource.  I'm not sure.
What do I need to do to get around this?
I'm assuming I need to logon into something.
Many thanks
TRW

Hi Praveen,
           I found this following procedure in the sap library. They r also said that 'Choose Delta Process Initialization mode on the Update tab page and select Initialization without Data Transfer'
          Thatz why I asked..I am confused now...please help.
Procedure
To activate data transfer to the delta queue, create an InfoPackage for your XML DataSource in order to initialize without a data request.
       1.      In the Modeling InfoSource tree of the Administrator Workbench , choose InfoSources ®Your Application Component ® Your InfoSource for Requesting XML Data ® myself BW System ® Create InfoPackage
       2.      Enter a description for your InfoPackage in the following dialog box. Select the XML DataSource and confirm your entries.
       3.      Edit the tab pages for the InfoPackage. Choose Delta Process Initialization mode on the Update tab page and select Initialization without Data Transfer.
       4.      Schedule the InfoPackage.
