Thank you so much jaikiran ji, I am delighted to get the reply. Now that you have answered most of the questions, i want to provide details on XML file, i m currently not using -ds.xml file of jboss rather using custom file named configurator.xml in which the root user,password,and IP where the database server is located.How can i make ejb read this file so that my connection to the database will be created? Thank you in advance. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4170969#...
