Grab bag

My grab bag is a collection of stuff that you might find useful. Software in the grab bag will usually work, but release cycles are completely random.

HotlinkingFilter

A JEE filter that prevents hot linking (bandwidth leeching). Download as a ZIP file, as a TAR.GZ file and as a TAR.BZ2 file.

ReDirector

An XML-based redirection script. Uses a simple XML file. Download as a ZIP file, as a TAR.GZ file and as a TAR.BZ2 file.

HashCache

The HashCache is a collision-free hash table that only stores hash codes from Objects, not the actual Objects themselves. This is useful when the most frequent operation is contains – for example in compilers when you’d like to quickly find out if a token is part of a list of keywords. Don’t forget to download the test case.

Instance

Create instance of any objects (even things like sun.misc.Unsafe) using Reflection. Doesn’t matter if there are no constructors or the constructors throw exceptions. Tested and works in a large number of VMs. Even works in Kaffe! Download as a ZIP file, as a TAR.GZ file and as a TAR.BZ2 file.
