Dimitri,
As someone already pointed out, your pk generation strategy might not
gaurentee absolutely unique integers under concurrent access situations.
This problem has been debated extensively on different forums/lists and
you can find the concise results of those discussions by taking a look at
The method you have chosen doesn't give unique pk values with more than one
thread/user.
There are many many ways to do this right, including I think an id
generator bean included with jboss. Look in the archives.

Hello!
I have a table in a mySQL database which I access through JBoss 3.0.0
(by means of CMP entity beans).
In this table I have an integer primary key. When creating a new
record in the table, I have to generate a new primary key with the
query
SELECT MAX(projectPrimaryKey)+1 FROM projects
