Java Naming and Directory Interface

Core infrastructure (glue) for locating objects or services within an application server

Also allows external clients to locate services

Important for clustering: hides actual location

Divided into API and SPI

Applications code against the API

Application servers provide the SPI

SPIs for accessing remote resources, such as LDAP, DNS, NIS, file systems, RMI registry

JNDI in Java EE JNDI is to Java EE what DNS is to Internet apps JNDI maps high-level names to resources like mail sessions, database connection pools, EJBs, and plain environmental properties JNDI organizes its namespace using Environmental Naming Context (ENC) naming convention:

Starts with java:comp/env

Private to each application

Contexts are delimited with a forward-slash (/)

JNDI ENC naming convention:

java:comp/env/var - Environmental variables

java:comp/env/url - URLs

java:comp/env/mail - JavaMail sessions

java:comp/env/jms - JMS connection factories and destinations

java:comp/env/ejb - EJB home interfaces

java:comp/env/jdbc - JDBC DataSources

JNDI on JBoss Supports both local (optimized) and remote (over RMI) access to named objects Provides a JVM-private app-shared java: context in addition to app-private java:comp Everything outside java: is public and externally visible Exposes JNDI operations over JMX invoke operations - allows access over HTTP/S Supports viewing JNDI Tree remotely Supports clustering through HA-JNDI Configured in ${jboss.server.config.url}/jboss-service.xml:

<mbean code="org.jboss.naming.NamingService"

name="jboss:service=Naming"

xmbean-dd="resource:xmdesc/NamingService-xmbean.xml">

<mbean code="org.jboss.naming.JNDIView"

name="jboss:service=JNDIView"

xmbean-dd="resource:xmdesc/JNDIView-xmbean.xml">

</mbean>

Client configuration ${jboss.server.config.url}/jndi.properties:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory

java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces

Remote clients would need to add:

java.naming.provider.url=jnp://jbosshost.domain.com:1099
