Look in the "Problems" tab, normally at the bottom of your Eclipse workspace. This will tell you what the problem is. Sometimes you just need to do Project > Clean and rebuild it.

On eclipse console tab it is not displaying anything. Just an alert box is displayed saying that "Your project contains errors, fix them and before running" – Khaja moin Jan 02 '11 at 10:43

Sure, but that's the CONSOLE tab. Look at the PROBLEMS tab. If it's not there, enable it with Window > Show View > Problems – Shawn Lauzon Jan 03 '11 at 03:46

That's a separate question, so really belongs on another topic, but most people suggest using XML as much as possible. Since I answered your original question, please mark it as answered. Thanks! – Shawn Lauzon Jan 04 '11 at 15:26
