Ok, either I can't navigate Sun's website to save my life, or the Java API specification is no longer available for download so one can have it on their local machine rather than having to access Sun's (or someone else's) webpages.
Have I missed something? I had it before, but accidentally deleted the directory it was stored in.. as I recall, it was obtainable as a .zip file.
Ideally, I'd like to be able to download and store on my local filesystem both the 5.0 and 6.0 API specs. Much easier and quicker to have it on my hard drive.
