[news.eclipse.tools] Re: Debugging JBoss with Eclipse question

[Rick Horowitz <rickhoro@xxxxxxxxxxxxx>]

Hi Igor,

I checked out the Eclipse/JBoss HowTo page.. thanks for the pointer!  I 
have some questions which perhaps you can answer. Sorry, I know some of 
these questions more correctly belong to the JBoss group.

1. Do you know if JBoss 4.0 works well enough to use to develop EJBs and 
run them?  If so, do you know if the JBoss 3.0 docs still match the 4.0 
release with the exception of new functionality?

2. Does JBoss 3.2 still match the descriptions in the 3.0 docs, with the 
exception of new functionality?

3. Can you send me your .project/.classpath files for JBoss 3.2? Text 
attachments would be fine.

4. In what way are the .project/.classpath files "not as nice", as you 
said in your posting?

5. I'm using Eclipse 2.1m5 and some things work differently from the 
Eclipse 2.0.1 mentioned in the HowTo. Specifically, the HowTo shows 
creating the "thirdparty" project and selecting the radio button, "Use 
Source Folders Contained in Project". This radio button doesn't exist in 
the 2.1m5 release. Any tips on how to handle that difference?

Thanks very much for your help.

Rick
