It's not entirely clear from the Tomcat documentation, but you aren't creating environment variables that can be retrieved using System.getenv. Instead, you are placing entries into the JNDI context. You'll want to retrieve them like this: // Obtain our environment naming context Context initCtx = new InitialContext(); Context envCtx = (Context) initCtx.lookup("java:comp/env"); String FOO = (String)envCtx.lookup("FOO"); // now FOO should have the value "bar" from your <Environment> The documentation for JNDI resources can be found here: http://tomcat.apache.org/tomcat-6.0-doc/jndi-resources-howto.html Hope that helps, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk06ARQACgkQ9CaO5/Lv0PDe9wCgmnx/XtBUNRa6xcGNpt5dGko0 9wgAnAuCWaMK1ZGwZgGwyJLYjh0R7kjW =nBdC -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
