### Example 1: Using JNDI data source connections of WebLogic Server

Using WebLogic as an example, take the following steps:

1. Start WebLogic server, navigate to <YourProjectName> > Services > JDBC > Connection Pools. In the Configuration tab, make sure that the connection you are going to use is there and correctly set up.
2. Browse to <YourProjectName> > Services > JDBC > Data Sources. In the Configuration tab, create a data source using the JNDI name MyJNDISample. Select the correct connection from the Pool Name drop-down list.
3. Open datasource.xml in the `<install_root>\bin` directory and add:

       <datasource-mapping>
       <datasource>
       <catalog-connection-name>ConnectionName</catalog-connection-name>
       <connection-type>JNDI</connection-type>
       <jndi-datasource>MyJNDISample</jndi-datasource>
       <user>youruserid</user>
       <password>yourpassword</password>
       </datasource>
       </datasource-mapping>

4. Build the JReport Enterprise Server WAR file using the makewar utility in the `<install_root>\bin` directory.
5. Deploy JReport Enterprise Server to WebLogic.
6. Run the report set that uses this connection.
