Re: [jetty-dev] How to access jndi out of webapp?

[Jan Bartel <janb@xxxxxxxxxxx>]

Andy,

I'm not quite sure what you're trying to do.  Assuming you have 
something like this in jetty.xml:

 <New id="mydatasource" class="org.eclipse.jetty.plus.jndi.Resource">
   <Arg></Arg>
   <Arg>jdbc/mydatasource</Arg>
   <Arg>......</Arg>
  </New>


Then you access that in your webapp as:
InitialContext ic = new InitialContext();
ic.lookup("java:comp/env/jdbc/mydatasource");


Outside of that, you can look it up as:
InitialContext ic = new InitialContext();
ic.lookup("jdbc/mydatasource");

Note that only works for jvm-scoped objects. You could look up
objects with other scopes, such as Server too, if you absolutely
needed to. Let me know if you want to do something like that and
I can show you how.

regards
Jan
