OSCache can be used directly to provide caching for any Java application. Using the OSCache tag library requires Servlet 2.3 and JSP 1.2 support (included in J2EE 1.3) to run properly. There is no dependency on a servlet container if the OSCache API is used directly.

So far OSCache has been tested in the following application servers and web containers:

• OrionServer(version 1.4.0 and above)
• Macromedia JRun (version 3.0 and above)
• BEA WebLogic Server (should work on version 8.1 and above)
• IBM Websphere (tested on version 5.0)
• Silverstream (tested on version 3.7.4)
• Caucho Resin (version 1.2.3 and above)
• Tomcat (version 4.0 and above)
• iPlanet (tested on version 6.0. Note that the caching filter has not been tested, only the taglibs)

This does not mean it will not run on other servers! It should run on any specification compliant container. If you have run OSCache successfully in other servers, please let us know and we'll add to this list.

The Caching Filter (for caching entire pages, and binary content such as GIFs and PDFs) requires Servlet 2.3 support. It is known to work on Orion, BEA WebLogic Server and Tomcat 4.0.

OSCache requires at least Java 1.4 for the installation.
