I have developing ejb 2.0 components by Pravin v. tulachan.
It is a good book and i have started to put the examples to the jboss 3.0 implementation with ant.
I had a quick look at the workbook and it looks pretty good. Will look into it in more detail soon.
I am working on distributing a set of the examples that use MySQL as the database.
This should be distributable pretty soon. Basically the EJBQL booleans in the where clauses that has been discussed in other threads has forced me to upgrade to v3.0.2 and I'm running into problems with the data source XML file being read properly.
If anyone is interested in the stuff I have so far, let me know. I've worked through all the examples between chapter 4 up to 7 and tested them in 3.0.0. It's the chapter 8 stuff that's giving me the problem at the moment.
Bill and Sacha, if you happen to read this, I'll be emailing you shortly to co-ordinate things better.
I was also interested in developing ready to deploy versions of these examples for Oracle. I would be more than happy to invest the time if someone would like to give me to a sandbox type Oracle database! ;)
