debugging/dev environment?
What are people using for debugging environments?
I was using IBMs VisualAge 3.0 with Tomcat 3.1M1 but when I 'upgraded' to
Tomcat 3.1Beta, it stopped working (yes, I uninstalled everyting and
reinstalled everything, unzipped all the jars, even deleted the "Tomcat
Version 3" project and totally rebuilt it).
I just can't get it working now, especially with Cocoon. various weird
problems (my hunch it that its a class loader issue). Tomcat/Cocoon work
fine standalone.
Any ideas? Other recs? Is anyone using Forte?
Thanks in advance.

Been there, done that. Still do when I need to, but as they say, life is
short.
In particular, I find that when I am learning a new project, a visual
debugger is the most efficient way for me to learn code paths.

I've looked at Kawa a couple times previously, but the combination of
a third rate editor, no debugger and no graphical GUI layout was not
very interesting. Certainly not kick-ass. It's been a while :).
Very interesting is the announcement on the Kawa site that they will
be integrating with CodeWright (a first-rate Windows editor).
It will be interesting to see the result (April 1 is the date).

You can do this in theory, but the problem is that it is not practical.
I've done this with both Jetty and Tomcat, but after a while the "real"
build process changes, and your local build starts failing. After this
happens enough times --- well it's just not fun anymore :).

Is there a true requirement to interoperate with ANT? Tomcat is all Java,
so in theory anything that can compile a set of java files should work.
VisualAge can compile Tomcat, if you can hunt down all the necessary source
files and resources in the distribution. Does anyone know of a reason why
simply compiling all the .java files would not produce a working Tomcat?

You can find a VisualAge CVS tool (vaj2cvs) at www.javadude.com
(http://javadude.com/vaj/resources/tools2x.html). It works reasonably well,
although it does require cvs to be set up in a pserver configuration.

Thank you very much, but that's what I'm doing now, and it is not a
very productive way to work. In other words, it sucks.
I've found Symantec Visual Cafe very usable of other kinds of projects
in the past, but am no longer amused to find the current version to be
as flaky as the early versions.
At first you could ascribe their problems to the fact that the product
was young, and they had incorporated more useful features than their
competitors - but it's been five-odd years now I and suspect their
development process is just plain broken.
Also their "project" model is simply too inflexible to allow for use
of ANT (the preferred way to build Tomcat). While ANT is interesting
in some ways, it might as well be a space alien as far as the existing
development environments are concerned.
IBM's VisualAge for Java is pretty neat, but insists on keeping all the
source files in their proprietary "repository", for which the number of
interoperable tools is roughly zero. So far as I can tell there is no
way to interoperate with ANT. Source code control for distributed
development (trivial using CVS and files) is either expensive (buy IBM's
TeamConnection for $$$) or awkward (export to files, checkin, update to
get other's changes, import files).
VisualAge *might* be extensible to understand ANT, and it *might* be
extensible to integrate with CVS - but that's a lot of work...
Borland's JBuilder is interesting in other ways. Haven't looked at it
from the point of view of integrating ANT and Jakarta.
I used another version of Emacs as my preferred development environment
on Unix for several years (several years back), but the GNU Emacs on NT
is a kind of a clunky Window application, and (of course) many of the
key bindings are different from what I'm used to :).
Personally I'm not concerned about initial ease of learning and use,
but I *am* strongly interested in the most productive environment.
One of the recommended "best practices" is to single step through any
and all new code that you write with a debugger. This sounds pretty
tedious, but I've found the payback well worth the time invested.
I find that at a good GUI debugger can be much more productive than
a command line debugger for this task, so I'm pretty dubious about
using Emacs wrapped around the JDK debugger.
Yes, I too am debugging my servlets largely with System.out.println()
and log files - but strategically this is a very poor choice.
To get out of low gear on Jakarta and servlet development:
1. We need to be able to use ANT as a build tool. This means that
build errors should land us in a editor at the point of the error.
2. We need to be able to work with a first class editor. The next
best thing is a second class editor in the IDE, and the ability
re-load changed files when edited by a first class editor.
3. We need to be able to efficiently inter-operate with CVS.
To my mind this doesn't require any form of integration, after
all "cvs update", "cvs diff" and "cvs ci" are pretty simple :).
4. We need a good efficient GUI debugger with at least some integration
with the editor, so you can mine your way through the sources when
the debugger turns up something interesting.
I'm using Windows NT for most of my software development development,
but I wonder if GNU Emacs with (perhaps) DDD as a jdb front end
might be a useful combination. Anyone tried this?
Anyone found a particularly good working combination?

I use Emacs for everything. You can get an extension called JDE at
http://sunsite.auc.dk/jde/ that will make debugging Java easier.

What are people using for debugging environments?
I was using IBMs VisualAge 3.0 with Tomcat 3.1M1 but when I 'upgraded' to
Tomcat 3.1Beta, it stopped working (yes, I uninstalled everyting and
reinstalled everything, unzipped all the jars, even deleted the "Tomcat
Version 3" project and totally rebuilt it).
I just can't get it working now, especially with Cocoon. various weird
problems (my hunch it that its a class loader issue). Tomcat/Cocoon work
fine standalone.
Any ideas? Other recs? Is anyone using Forte?
Thanks in advance.
