|Re: [jetty-users] Testing with JNDI|
Not sure I still understand what you are trying to do. If you do new
Resource(_server, "jndiName", myobject) then you cannot reference it
inside your webapp inside of java:comp/env namespace unless you have a
web.xml <resource-ref> setup for it to bind it in there (that's using
the normal jetty WebAppContext and related classes).
If you're saying you want to do new Resource(_server, "jndiName",
myobject) and then reference it in other code as
java:comp/env/jndiName and you don't want to use the usual
WebAppContext and related classes, then you should:
1. call Resource foo = new Resource(_server, "jndiName", myobject)
2. create a separate fake classloader and set that one up on the
ServletContextHandler or ContextHandler
3. set the fake classloader as the thread context classloader
4. call foo.bindtoENC("jndiName");
5. start your ServletContextHandler or ContextHandler
Steps 2-3 is only necessary if the ContextHandler or
ServletContextHandler creates its own classloader in doStart() if one
is not already set - I can't remember if it does or not (WebAppContext
certainly does), but you can check the code. You just want to make
sure that the classloader that you do the bind to java:comp/env with
is the one that you will be doing the lookup with.
