[jetty-users] Can Jetty user bind JNDI by themselves?

[Lin Ren]

Hi,

 

I’m currently trying to bind a JNDI by myself in the Bean code (not in the application), code is like below:

 

   try {

      // Bind receiver under server name

      jndiName = WlngContext.getInstance().getServerName();

final String JNDI_PREFIX = "event_channel/";

      fullJndiName = JNDI_PREFIX + jndiName;

      namingContext = new InitialContext();

      localReceiver = new EventReceiverImpl(this);

      namingContext.bind(fullJndiName, localReceiver);

      eventContext = (EventContext) namingContext.createSubcontext(JNDI_PREFIX);

      namingListener = new EventReceiversListener(this);

      eventContext.addNamingListener("", EventContext.ONELEVEL_SCOPE, namingListener);

      refreshCachedEventReceivers();

    } catch (Exception e) {

      // Cleanup what we've done before throwing exception

      System.out.println("================================" + e.getMessage());

      e.printStackTrace();

      deactivate();

      throw e;

    }

 

And I got an exception said that:

 

javax.naming.NameNotFoundException: event_channel is not bound

         at org.eclipse.jetty.jndi.local.localContextRoot.bind(localContextRoot.java:608)

         at org.eclipse.jetty.jndi.local.localContextRoot.bind(localContextRoot.java:547)

         at javax.naming.InitialContext.bind(InitialContext.java:425)

         at com.bea.wlcp.wlng.event_channel.rmi.EventBroadcasterRmi.activate(EventBroadcasterRmi.java:54)

 

My question here is, can we bind JNDI by ourselves? If yes, how can we do for that?

 

Thanks!

That error tells you that "/event_channel" doesn't exist.

You are trying to bind "/event_channel/${serverName}" before the parent
even exists.

Hi,

 

Thanks a lot for your reply!

 

Then how can I bind a resource to a tree like name, such as “a/b/c”, please? We’re trying merge from Weblogic to Jetty, and seems something different between Weblogic and Jetty on the JNDI name binding


 

Thanks!

Make the subcontext first and then bind the object into it.

Like Jan says, make the subcontext first, then the others.

So "a/b/c" means you'll ..

* create subcontext "a"
* create subcontext "b" (from "a")
* create subcontext "c" (from "b")

This is how the jndi layer/api works.

The jetty implementation has a non-standard way to skip the subcontext
creation called "deep binding"

In the various javax.naming.Context methods that pertain to Environment (as
a Hashtable usually), setup an entry with key
"org.eclipse.jetty.jndi.deepBinding" with value of "true".
This feature was implemented in Jetty for the various EE folks to use (such
as TomEE, CDI, and OpenEJB).
