This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
If I remove messages="true" then I get no error, but no text appears either. The kicker is that I made this jsp by copying an existing jsp, and this code works in the original, but not in the copy, which only has a few changes. This leads me to believe this is some sort of set-up issue, but I don't know what. Can anyone give me a clue?
