Rakesh,
I think you are in a wrong thread for this, here the issue is a AS7.x naming problem. Please use the correct thread or open a new one.
If I remember correct, in AS5 there is a property use-java-context that you can set to access the datasource outside the server-jvm. See datasource configuration.
But I'm not sure whether this will work in AS6.
In AS7 there is no way to access the datasource pool outside the server.
