I'm learning J2ee and I'd like to use and debug
Java adventure. I tried to find some information but found nothing.
What I tried to debug , is to start the j2ee server by adding the following options into the bin/asadmin.bat file:
-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
This it doesn't work because the j2ee server is started with the javaw.exe virtual machine. So I'm stuck here.
My first question: 1- what visual debugger is great to debug J2ee apps ??
I'd like to known what are the steps to:
2- how to start the j2ee server in order to attach the jdb or a visual
debugger ?
3- when starting the j2ee server, what do i have to do in order to step
into the code source of Java adventure and follow function calls ?
4- how do I have to start the jdb to attach to the J2ee server ?
5- Any useful tip to debug J2ee apps ! :-)

Thanks in advance !

Have you seen this? (I assume "asadmin" means you're using SunONE)

Hello Sam,
IMHO - WebSphere Studio Application Developer is the best IDE, but YMMV.
You can dowload a free eval copy, but it is big, but it is good. I will be happy to answer any question about it. Post them right here and I'll check back.

Thanks for your responses.
Yes I'm trying to use SunOne. In fact I'm trying different Apps to debug Java Adventure blueprint. I have to give a deeper try for debugging with Sunone

The problem I have with websphere is that I'm not able to create a project that contains all the file from the Java Adventure Blueprint from Sun.
I guess the first step is to be able to create a project that include all files from adventure.
Do you have an idea how to do that
My second question is, if I use Websphere to debug, which Apps server do I have to use in order to be able to debug ? Do I have to use Websphere apps server or any J2ee compliant server ?
Thanks in advance.

I agree. Here's the link: http://aspose.com/file-tools
