Sun Java System Web Server 7.0 Update 4 Developer's Guide to Java Web Applications

Enabling the file Session Manager

You can specify file explicitly to change its default parameters. To do so, edit the sun-web.xml file for the web application as in the following example. Note that persistence-type must be set to file.

           <session-manager persistence-type=”file”>
                 <property name=reapIntervalSeconds value=20 />
                 <property name=directory value=sessions />

For more information about the sun-web.xml file, see Chapter 9, Deploying Web Applications.
