Check these: Isolation is set using flags in your configuration or jboss_web/app files.
The benefit is that every application has its own class loding space and you can avoid lots of wierd problems. The down side is that isolation can affect jndi lookup in general, and lookup data source specifically. To read about isolation and class loding use the following: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossClassLoadingUseCases http://wiki.jboss.org/wiki/Wiki.jsp?page=ClassLoadingConfiguration Please let me know if you can get both isolation and datasource lookup work at the same time.
