JDBC data source SAPSR3DB connection issue

Hello All,

We have recently upgraded to 7.3 system and one of the custom java application is not working. The application connects to standard data source for fetching data. Earlier data sources were maintained in visual admin but in NWA, data sources are available in NWA. When we are trying to launch the application, exception is thrown saying:

Naming Exception occured - Object not found in lookup of SAPSR3DB"

Need hint or direction to fix the issue. Please help in case anyone has any experience with JDBC connectivity in 7.3.

Regards

Amit
