I don't know what happened but in my eclipse I created a Dynamic Web project and was editing it. For some reason I don't have the source and design tabs any more and I can't edit the page visually i can only access the code page?
I'm just starting out with Eclipse and going through the JSP tutorial (the sample login page), and this was not made clear. On my PC, a new JSP page opens in the text-based editor by default, not the Web Page Editor.
I have a feeling these forums will be invaluable, especially when starting out.
