## Configuring another connection as a substitute for the catalog connection

Normally, after a report has been created, it is fixed to a specific catalog connection. With the Java EE Data Source Support feature, you can change to another runtime JDBC or JNDI data source to run reports. This allows you to control the catalog data source connections in JReport Server to connect dynamically to your production data sources.

This section focuses on the following:

- Configuring the datasource.xml file
- The connection priority
- Reloading connection information from datasource.xml
- Integrating JReport Server with your Java application server
- Example 1: Using JNDI data source connections of WebLogic Server
- Example 2: Using JNDI data source connections of JBoss server
