With people expressing interest in this topic on this list, I thought I'd
share what I've seen for what it's worth.
I have spent quite a lot of time researching some of the tools for
generating EJBs which are being worked on in the Open Source community, in
preparation for my company's efforts to get access to a robust tool for this
purpose. One requirement of our solution is that we can drive it from a UML
model expressed in XMI. For the most part that makes a Javadoc based tool
require an extra step, XMI -> Java -> Java, vs XMI -> Java if we use
something like XSLT. It is not yet clear whether we will open source our
tool, though I believe we are commited to doing so.
Here are some of the more viable tools I've found (other than Rickard's of
course!)
www.percolator.org - provides CMP entity beans, session facades,
value holders and more for several app servers including jBoss, but you'll
need to tweak the generated xml files since they wrote their templates
before differential metadata. Percolator uses a simple XML file format for
input.
www.mousetech.com/EJBWizard.html - generates BMP/CMP entity beans and
session beans along with some JSP/Servlets and client code to exercise the
beans. Uses a GUI to enter information or else a simple XML file format.
Doesn't do jBoss xml files, but I expect some enterprising soul could modify
the templates to do this. I have delivered an XSLT stylesheet for
converting XMI to EJBWizard input files to the author of the program.
My personal favorite for creativity -
www.nordija.com - Their bean builder is an application running on their
server which allows you to enter an EJB description and then they generate
the code which you cut and paste from your web browser. They also provide a
capability to save the bean description to XML which you can cut and paste.
They also provide a simple framework for optimistic locking.
And another Javadoc code generation tool written up in the August, 2000
edition of JavaWorld -
http://www.javaworld.com/jw-08-2000/javadoc/javadoc.zip.
I am interested in hearing from anybody on the list who is also interested
in working on an EJB generator as I expect for the most part that there is
much in common in the templates used for code generation even if some people
use Javadoc and some XML.
Cheers

I've noticed that ;-).

I think what makes most sense is that we take a shot at our
reimplementation (which we need for a project that's just started) and
once
we have a critical mass that's worth talking about, we'll send you
code/design docs so you can see for yourself if it fits under the jboss
umbrella. right now our primary focus is on our project (but the again
it
never hurts to code against real world requirements, except for the
deadlines ;-) so we're doing our implementation anyway.
makes sense?

robert
