  org.eclipse.rap.rwt.service.FileSettingStoreFactory

All Implemented Interfaces:

SettingStoreFactory

public final class FileSettingStoreFactory
extends java.lang.Object
implements SettingStoreFactory

A setting store factory that creates instances of FileSettingStore.

This implementation uses the following strategy to determine the path for persisting the data of the session store instances.

1. Use the directory specified by the init-parameter "org.eclipse.rap.rwt.service.FileSettingStore.dir" in the web.xml.
2. Use the directory specified by the "javax.servlet.context.tempdir" attribute in the servlet context.
3. Use the directory specified by the "java.io.tempdir" property.

The first path that can be obtained from the above choices (in the order given above) will be used. If the path determined does not exist it will be created.
