(back to JavaTips)
Example database datasource configs are in docs/example/jca.
JBoss and Oracle's jdbc driver don't play nice unless you turn on "TrackConnectionByTx".
Give jboss more memory than the java default - you'll be glad you did (or sorry if you don't)!
Pay attention to the pool sizes in
standardjboss.xml
, especially the Stateless Session Bean pool size, which is 100 by default. This seems pretty low, at least if you have methods that take a while to perform. If you're using MDB's you'll want to bump the
MaximumSize
in the Message Driven Bean
container-invoker-conf
to something larger than the default (which is 15).
A strange error in jboss happened when I had the same ejb-jar declared twice in the application.xml. It caused strange errors that looked like classloader problems. For example, one error was an access violation error when one class tried to access a package-protected method of a class in the same package. Another had to do with a class not being able to call a method in another class because it couldn't find the appropriate signature, even though everything appeared to match.
