Hi, for starters, this is my first post. Second, I am having some trouble using Eclipse, when I create a new Java class and run it, I constantly get a ClassNotFoundException, these Java classes run just fine in other IDEs (i.e. - BlueJ). I don't get this error when I run an older class. If I run a file created outside Eclipse, it gives the option for ant builds, and I don't get an error, but the file won't execute at all. Any help would be apreciated.

Make sure that the class file has been compiled.

From the Project menu in the menu bar, make sure that Build
Automatically is enabled. Unless you've found specific circumstances in
which you want to turn it off, you can save yourself a lot of headaches
by just leaving it on.

I think you'd benefit a great deal by going through the tutorials. Open
Help > Help Contents, then find the Tutorials under Java Development
User Guide > Getting Started.

Also check out the tutorials at http://www.vogella.de/eclipse.html
