Dynamic loading of jars

[estebanlm]

Hi!
I need to load/unload jars dynamically, and I don't know how do that...
In october someone asks the same question and get as answer: "go to the training!", well, I live in the other side of the word, and I don't have the time and the money that's needed for do that (and my english sucks too), so PLEASE, HELP ME!!! How I load the libraries...
Thanks a lot
Esteban

Try using a classloader ...

need more info. What classloader scope? server? app? When? Why?

in 2.4 you can use an ear or maybe the j2eescopedDeployer to reversibly load app-scope jars.

in 3 you can use sars or classpath refs from a --service.xml file. There are lots of examples in the 3 distro and lots of discussion/arguments on the dev list.
