Re: [jetty-users] Binding Weld BeanManager to JNDI in servlet.Context //

[Jan Bartel <janb@xxxxxxxxxxx>]

Hi Ondra,

FYI the jetty jndi libary allows you to bind your jndi entries to
the context, or to the server, or to the jvm as a whole (== new 
Resource (null, "BeanManager", ref)).

To retrieve an object bound using the NamingEntry classes, try
using the NamingEntryUtil.lookup() method. Supposing you have bound
"BeanManager" as:
   new Resource( ctx, "BeanManager", ref );

then you can retrieve it with:
   NamingEntryUtil.lookup(ctx, "BeanManager");

Alternatively, you not use jetty's convenience classes for scoping
names to servlet contexts/servers etc, and simply manage the namespace 
yourself using standard jndi calls. The underlying
jndi impl will be provided by jetty, if you have jetty-jndi jar
in your classpath:

InitialContext ic = new InitialContext();
ic.bind("BeanManager", ref);

...

ic.lookup("BeanManager");

hope that helps,
Jan
