I make customerBean.java for connecting and read content of datatable. I handling connection over datasource: Database is Derby . I made datsourc in jboss7.1 standalone and I can ping database. @Resource(name="java:/MyDerby", type=DataSource.class)     private DataSource ds; Is it correct that JDNI for @Resource written above?  I made datsourc in jboss7.1 standalone and I can ping database. But when I start aplication on server I have got error on web server with code http status 500. *************************************************************************************************************** **************************Here is logs from web browser: h1.
