Avoid Frustration

Here is a summary of everything I currently know about which versions of the JDK, Tomcat, Struts, and the Struts Bridge are compatible with one another - along with download links for each. If something's not on this list, that doesn't mean it doesn't work - it just means that I haven't tried it. If you are using a configuration not listed here (even if it's just Tomcat without Struts or the Bridge), please comment so I can add it to the list to make it more complete.
