Thanks, Sir, I am getting closer. Now Jboss can find my class file and run my class file. It is also indicates it has been able to make MS SQL server connection. The only problem is ii can not find my jsp file and a property file. I check the war file and found the pass of jsp file and property file are incorrect. The jsp file path is project/jsp/**.jsp and the path of propety file should be project/WEB-INF/**.properties But in the war file, they are project/**.jsp project/**.properties I just can not make the path right. Here is my code of war in build.xml. Could you please indicate what wrong cause this problem? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4133972#...
