Thanks, Sir, Now I can see the HelloWorld example after modifying the build.xml. But I still can not see my own application which invokes MS SQL server. The meesage I have is : 2008-03-03 12:28:21,156 ERROR [STDERR] java.lang.ClassNotFoundException: No ClassLoaders found for: com.microsoft.jdbc.sqlserver.SQLServerDriver It seems the MSSQL jar files are not found. But I did include them in the jar war file. I should send you my war file but when I run the jar or war commands in coomandline, it says there is no jar command recognized. But I did use "war" in my build.xml. Could you please tell what I have to set to make coommand line knows the jar coomand? Thanks!
