Based on the error message: Apparently wrong driver class specified for URL: class: com.microsoft.sqlserver.jdbc.SQLServerDriver I suspect that the com.microsoft.sqlserver.jdbc.SQLServerDriver class in not present in the sqljdbc.jar. You might double-check the documentation for the sqljdbc.jar file to verify the driver classname. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253411#...
