I'm also having trouble running the JBoss/Eclipse tutorial. I'm running Eclipse 3.1, Linux, JBoss 3.2.8, JBoss Eclipse IDE 1.6.0 GA. I get all the way to the part where the server is started in the tutorial, but then two things happen. First of all, double-clicking in the left column does not create breakpoints, nor is there an right-click option there to add a breakpoint, for example in ComputeServlet.java.
Secondly, there are "Problems" in my ComputeServlet.java code (which show up as exceptions if I try to submit a number to be computed on the web form). The are all resolving problems:
FiboHome cannot be resolved to a type - on every line on which FiboHome appears, including
private FiboHome home;
Fibo bean = home.create();
Sorry, I'm stupid. I forgot to import the relevant classes.
I also found a solution to my two other anomalies regarding breakpoints, code-folding and code assist . . . it seems that EclipseColorer (I was using 0.7.1) interferes with other editors, specifically in these kind of dynamic editor behaviors. I disabled it, and everything works well now.
