Looks like you are doing a lookup of the datasource from this class. Have you deployed the datasource in the deploy folder of the server using a *-ds.xml? If yes, can you post its contents here? Also, remember that the datasources are by default bound to the java: namespace. So if you have specified MSSQLDS as the jndi-name in the ds.xml file, then your lookup code should be using java:/MSSQLDS
