I upgraded to Eclipse 3.0.1 and MyEclipse 3.8.2 and installed the myeclipse patch.

Eclipse:
Version: 3.0.1
Build id: 200409161125

MyEclipse:
3.8.2+QF20041020

I rebuilt and redeployed the HelloWorld web project in Tomcat 5. When I try to set the breakpoint on the line

out.println("Hello World");

I get an error msg at the bottom left:

Breakpoint cannot be set at the given location

Can you check your log file for exceptions?

<workspace dir>\.metadata\.log

There is no exception in the .log file

I also cannot get MyEclipse code completion to work i.e.

<%out.

if I now enter ctrl->space keys, I get a "No completions available" msg

Are you sure you are using our editor? If you right click on your JSP file > Open With > MyEclipse JSP Editor?

It seems like that was the problem all along. My jsp files were configured to be opened with the Java editor. I changed the association to the MyEclipse JSP editor and now I can also set the breakpoint correctly on the JSP.

Glad its working.
