Java JDK installation on Windows

Installing Java on Windows for development can be one of the trickier things, especially if you're looking for Java 1.5 vs. 1.6: Java 1.5 is not readily available for download. However, some digging reveals this great site with a link to the download (which requires registration). From there, you can find the 32- and 64-bit versions of the Windows' installers.
