There is a difference between Tomcat and JBoss descriptors about Datasources... It is the source of a lot of mess in web applications.
Tomcat: java:comp/env/jdbc/<NAME> JBoss: java:<NAME> A common solution is to include the full environment string into a separated properties file (avoiding the web.xml auto loading by the container): Properties config = new Properties(); config.load("yourConfigFile.properties"); String name = config.getProperty("datasource"); InitialContext context = new InitialContext(); DataSource dbSource = (DataSource) context .lookup(name); Note: I“m working on an Open Source project, which contains the complete source code to access MySql database through Tomcat - if you are interested, you can check the code at: https://cejug-classifieds.dev.java.net/source/browse/cejug-classifieds/web-app/ best regards, Felipe Gaścho On Wed, 09 Feb 2005 21:03:30 -0500, Kris Schneider <[EMAIL PROTECTED]> wrote: > Try an <env-entry> instead of a <context-param>: > > <env-entry> > <env-entry-name>dataSource</env-entry-name> > <env-entry-value>jdbc/RestaurantDS</env-entry-value> > <env-entry-type>java.lang.String</env-entry-type> > </env-entry> > > String envBase = "java:comp/env/"; > Context ctx = new InitialContext(); > String dataSourceName = (String)ctx.lookup(envBase + "dataSource"); > DataSource ds = (DataSource)ctx.lookup(envBase + dataSourceName); > > That way you don't need access to a ServletContext instance. > > Jack Lauman wrote: > > Schalk: > > > > I need to use JDNI... this is a JBoss DataSource.
