strange hour to be having a conversation with myself over the mailing list, but...
don't understand all the details, but googling reveals that the problem is that I'm using java 1.4 and that class is in 1.5, so I either install some library that provides the classes or upgrade to 1.5 (happily enough, was going to do this anyway) This will probably solve the problem. I'd still appreciate the JSON package recommendations just in case, though... On 6/8/07, Ronnie Maor <[EMAIL PROTECTED]> wrote:
