Kannan,
There is also one more thing you might want to consider if you are using any kind of relational connection like oracle using TNS.ora files.
While you run from the client software in you machine it uses your local connections setup (e.g. TNS.ORA) however while you trying to see the data from Launchpad it essentially uses the connections (TNS.ORA) present in the BOE server which might point to different database with the same connection name.
Thanks!!
