It's seems there is some bug in Spring deployer when JBoss is started as Windows native service. When JBoss server is started from console then everything works fine. But after it started as service my client application gets next exception. java.lang.reflect.UndeclaredThrowableException at $Proxy0.getAllPreduzeca(Unknown Source) at

library available to my client, I found out that problem was in creating dataSource bean. Spring deployer was not able to properly create it, because it complains that can't find url and jdbc driver. I think when JBoss is started as service then Spring deployer was not able to read jboss-spring.xml file. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966119#...
