Answer / Anjali Chaudhary

To achieve datasource-less (DSN-less) connectivity in Java 2 Enterprise Edition (J2EE), you can use the Java Naming and Directory Interface (JNDI) API. Here's a brief example of how to configure and access a database using JNDI:

1. Define the resource in your deployment descriptor (web.xml or application.xml).

2. Write code to look up the data source from JNDI context, typically in a utility class.

3. Use the data source object to create a connection and perform database operations as needed.
