Réf. : Accessing environmental variables

You must first create an initial context object like this
 Context ctx = new InitialContext();

  and acces your value like this
String value =(String)ctx.lookup("java:/comp/env/owner");

Objet :   Accessing environmental variables


How does one access these environmental variables being assigned from the
web.xml file?

I have tried accessing the servletContext presuming it would be available
there but no luck - its coming back null.  :(

    ServletContext application = getServletContext();
    String owner = (String)application.getAttribute("owner");

And here's my variable definition from the web.xml file:

   <!-- Environmental Variables Definitions -->
   <env-entry>
     <env-entry-name>owner</env-entry-name>
     <env-entry-value>Neal</env-entry-value>
     <env-entry-type>java.lang.String</env-entry-type>
   </env-entry>
   <!-- /Environmental Variables Definitions -->


Thanks.
Neal

RE: Réf. : Accessing environmental variables

Posted by neal <ne...@yahoo.com>.
Ooooh!

I saw a similar example for connection pooling in Tomcat (using the intial
context to retrieve settings).  I didn't realize that was also how to gain
access to the environmental variables.  And I guess that's why I couldn't
find the docs ... I didn't realize it was a JNDI topic.

:)

THanks!

Neal
