How to see JNDIView using Java based DMR APIs in EAP 6 ?

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 6.x

Issue

• How to see JNDIView using Java based DMR APIs in EAP 6 ?

Resolution

• The DMR code implements following CLI command :

/subsystem=naming:jndi-view

To run code JndiInfo.java follow below steps :

1. Create the management relem user and password admin/admin12# with the help of ./add-user.sh or add-user.bat

2. Set JBOSS_HOME as per JBoss installation and then set CLASSPATH with following jars :

export CLASSPATH=$JBOSS_HOME/modules/system/layers/base/org/jboss/as/cli/main/jboss-as-cli-7.3.0.Final-redhat-14.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/as/controller-client/main/jboss-as-controller-client-7.3.0.Final-redhat-14.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/as/protocol/main/jboss-as-protocol-7.3.0.Final-redhat-14.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/dmr/main/jboss-dmr-1.2.0.Final-redhat-1.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/logging/main/jboss-logging-3.1.2.GA-redhat-1.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/remoting3/main/jboss-remoting-3.2.18.GA-redhat-1.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/threads/main/jboss-threads-2.1.1.Final-redhat-1.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/staxmapper/main/staxmapper-1.1.0.Final-redhat-2.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/xnio/main/xnio-api-3.0.7.GA-redhat-1.jar:$JBOSS_HOME/modules/system/layers/base/org/jboss/xnio/nio/main/xnio-nio-3.0.7.GA-redhat-1.jar:.:

3. Replace localhost and management port 9999 as per environment. Compile code and run it.
