I'm having problems reading global environment variables from a servlet
running in a tomcat container.

I'm creating a datasource and several environment variables through the
tomcat admin screens and then trying to access them from my web
application with no success.

Any information or suggestions as to where I am going wrong would be
appreciated.

Here's the tomcat admin screen for a typical environment variable.
Name: opensite.repository
Type:   java.lang.String
Value:  d:\David\repository
Override Application Level Entries: Yes
Description: Path to opensite repository

Here's the corresponding entry in web.xml
<resource-env-ref>
  <resource-env-ref-name>opensite.repository</resource-env-ref-name>
  <resource-env-ref-type>java.lang.String</resource-env-ref-type>
</resource-env-ref>

And here is the java code to access the variable.
          try {
            Context ctx = new InitialContext();
            m_envCtx = (Context)ctx.lookup("java:comp/env");
          } catch (Exception e) {
            if (m_inContainer)
               m_log.log(Level.WARNING, "Can't get container
context", e);
          }

          try {
            m_repository = (String)
m_envCtx.lookup("opensite.repository");
          } catch (Exception e) {
            m_repository = m_tempDir + File.separator +
"opensiterepository";
          }

The entry in server.xml written by the admin program is as follows:
  <Environment description="Path to opensite repository"
name="opensite.repository" override="true" type="java.lang.String"
value="d:\David\repository"/>
