#### Specifying data source in web.xml (for the WAR mode)

When integrating the JReport Enterprise Server in a WAR package, you can specify the dsInfo in the WEB-INF/web.xml file using the `<env-entry></env-entry>` or `<context-param></context-param>` tags. However, the use of the `<env-entry></env-entry>` tags is the recommended way since the tags are also supported in ejb-jar.xml (if you call the server API in your EJB).

The following is an example of specifying the dsInfo in WEB-INF/web.xml using the `<env-entry></env-entry>` tags:

    <web-app>
    ...

    <env-entry>
    <env-entry-name>jreport.datasource.systables</env-entry-name>
    <env-entry-value>jndi://resource-name</env-entry-value>
    <env-entry-type>java.lang.String</env-entry-type>
    </env-entry>
    </web-app>

The following is an example of specifying the dsInfo in WEB-INF/web.xml using the `<context-param></context-param>` tags:

    <web-app>
    <context-param>
    <param-name>jreport.datasource.systables</param-name>
    <param-value>jndi://datasource_name_which_is_predefined</param-value>
    </context-param>
    ...

    </web-app>
