I've just spent an excessive amount of time trying to get Content Delivery set up on my SDL Tridion 2011 SP1 image. I couldn't get the HttpUpload web page working, no matter how much I tweaked the various settings. Then I gave up on that and tried setting up a deployer service instead. Still no joy; it wouldn't start. Fortunately I was able to call on my friends in the Tridion community, and Nuno Linhares came up with the answer. It turns out that the specific update of Java I had installed somehow doesn't get along with some of the other pieces in the puzzle. According to Nuno, it had something to do with using MSSQL as well, but frankly, I was just pleased to find that when I uninstalled 6u29 and installed 6u30, everything worked fine. Thanks Nuno.
