WildFly JNDI: What the difference between jboss and global

Question

We have JavaEE specifiaction: http://download.oracle.com/otn-pub/jcp/java_ee-7-fr-spec/JavaEE_Platform_Spec.pdf?AuthParam=1478532325_a9dcd40740691777eb0782e6a8bad14b

In "EE.5.2.2" we can see: "java:global – Names in this namespace are shared by all applications deployed in an application server instance."

Also, we have namespace java:jboss - https://docs.jboss.org/author/display/AS71/JNDI%20Reference.html

I can't find information about difference in these namespases and about purpose of java:jboss.

Are they similar or what the difference?

Answer 1

The java:module, java:app and java:global namespaces were introduced in Java EE 6 because a platform independent definition of these JNDI scopes did not exist (in particular java:global).

Prior to Java EE6, the various vendors defined their own JNDI naming schemes. java:jboss is an example of this. These namespaces typically had a global (server or cluster wide) scope.

JBoss AS 7 and newer still support the java:jboss namespace in order to provide support for applications that have been ported from older versions of JBoss AS (6.x and earlier).
