Have a look at: http://wiki.jboss.org/wiki/Wiki.jsp?page=HowCanIAccessADataSourceFromAClient However, this is not a recommended approach as mentioned at http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigDataSources anonymous wrote : Note: JBoss does not recommend using this feature on a production environment. It requires accessing a connection pool remotely and this is an anti-pattern as connections are not serializable. Besides, transaction propagation is not supported and it could lead to connection leaks if the remote clients are unreliable (i.e crashes, network failure). If you do need to access a datasource remotely, JBoss recommends accessing it via a remote session bean facade.
