Class MemoryDatabasePlugIn

java.lang.Object
  org.apache.struts.apps.scriptingmailreader.plugin.MemoryDatabasePlugIn

All Implemented Interfaces:

PlugIn

public final class MemoryDatabasePlugIn
extends Object
implements PlugIn

MemoryDatabasePlugIn initializes and finalizes the persistent storage of User and Subscription information for the Struts Demonstration Application, using an in-memory database backed by an XML file.

IMPLEMENTATION WARNING - If this web application is run from a WAR file, or in another environment where reading and writing of the web application resource is impossible, the initial contents will be copied to a file in the web application temporary directory provided by the container. This is for demonstration purposes only - you should NOT assume that files written here will survive a restart of your servlet container.
