How to view the JNDI tree in WildFly

by

The naming subsystem provides an overview of the local JNDI namespace. The Jakarta EE platform specification defines the following JNDI contexts:

  • java:comp – The namespace is scoped to the current component (i.e. EJB)
  • java:module – Scoped to the current module
  • java:app – Scoped to the current application
  • java:global – Scoped to the application server

In addition to the standard namespaces, WildFly also provides the following two global namespaces:

  • java:jboss
  • java:/

Please note that only entries within the java:jboss/exported context are accessible over remote JNDI. For web deployments java:comp is aliased to java:module, so EJB’s deployed in a war do not have their own comp namespace.

You can view the JNDI binding in two ways: from the CLI or from the Web admin interface

Using CLI

Connect. Then navigate to the naming subsystem and run the jndi-view command:

[disconnected /] connect

[[email protected]:9990 /] /subsystem=naming:jndi-view
{
    "outcome" => "success",
    "result" => {
        "java: contexts" => {
            "java:" => {
                "ConnectionFactory" => {
                    "class-name" => "org.hornetq.jms.client.HornetQJMSConnection
Factory",
                    "value" => "HornetQConnectionFactory [serverLocator=ServerLo
catorImpl [initialConnectors=[org-hornetq-core-remoting-impl-invm-InVMConnectorF
actory?server-id=0], discoveryGroupConfiguration=null], clientID=null, dupsOKBat
chSize=1048576, transactionBatchSize=1048576, readOnly=false]"
                },
. . . . .
}

If running in Domain mode, include the host name and the target server in your command. Example:

/host=master/server=server-one/subsystem=naming:jndi-view

Using the Web Admin Console

Just log in to the admin console and select the Runtime upper Tab. From there, click on the View button in the JNDI subsystem:

jndi view wildfly jboss

Fetch the JNDI Programmatically

Finally, you can dump the JNDI Context of the application server using the javax.naming.NamingEnumeration Class. Here is a simple method which print recursively the JNDI tree under “java:jboss“:

public void discoverJndi(String path, Context context) throws Exception {
    try {
        NamingEnumeration<NameClassPair> list = context.list(path);
        while (list.hasMore()) {
            String name = list.next().getName();
            String child = path.equals("") ? name : path + "/" + name;
            System.out.println(child);
            discoverJndi(child, context);
        }
    } catch (Exception e) {}
}

Then, to explore under the JNDI “java:jboss” just use the above method as follows:

discoverJndi("java:jboss", new InitialContext());

Here is a sample output from WildFly Console:
