Example of remote EJB invocation on JBoss 7

Example of remote EJB invocation between JBoss 7 instances.

Mini-How-To

1. Unzip JBoss into MASTER and SLAVE instances and build movie-manager:

   milad@linux-pc-0018:$ cd zips milad@linux-pc-0018:/zips$ unzip jboss-eap-6.1.0.Alpha.zip ... milad@linux-pc-0018:/zips$ mv jboss-eap-6.1 ~ milad@linux-pc-0018:/zips$ cd milad@linux-pc-0018:$ cp -r jboss-eap-6.1 jboss-eap-6.1-slave milad@linux-pc-0018:$ cd projects/movie-manager milad@linux-pc-0018:/projects/movie-manager$ mvn clean install ... [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS [INFO] ------------------------------------------------------------------------ [INFO] Total time: 9.534s [INFO] Finished at: Thu Sep 26 09:45:46 CEST 2013 [INFO] Final Memory: 19M/490M [INFO] ------------------------------------------------------------------------ milad@linux-pc-0018:/projects/movie-manager$ cd movie-manager-dist/target/ milad@linux-pc-0018:/projects/movie-manager/movie-manager-dist/target$ unzip movie-manager-dist-1.0.0-SNAPSHOT-distribution.zip ... milad@linux-pc-0018:/projects/movie-manager/movie-manager-dist/target$ cp movie-manager-ear-slave-1.0.0-SNAPSHOT.ear /jboss-eap-6.1-slave/standalone/deployments/ milad@linux-pc-0018:/projects/movie-manager/movie-manager-dist/target$ cp movie-manager-ear-master-1.0.0-SNAPSHOT.ear /jboss-eap-6.1/standalone/deployments/ milad@linux-pc-0018:/projects/movie-manager/movie-manager-dist/target$ cp -r modules/com/ /jboss-eap-6.1/modules/ milad@linux-pc-0018:/projects/movie-manager/movie-manager-dist/target$ cp -r modules/com/ /jboss-eap-6.1-slave/modules/ milad@linux-pc-0018:/projects/movie-manager/movie-manager-dist/target$ cp standalone-full-master.xml /jboss-eap-6.1/standalone/configuration/ milad@linux-pc-0018:/projects/movie-manager/movie-manager-dist/target$ cp standalone-full-slave.xml ~/jboss-eap-6.1-slave/standalone/configuration/

2. Add the "ejb" application user to the SLAVE instance and start it up:

   milad@linux-pc-0018:/jboss-eap-6.1-slave$ export JBOSS_HOME=/home/local/SPSSIT/milad/jboss-eap-6.1-slave milad@linux-pc-0018:/jboss-eap-6.1-slave$ bin/add-user.sh

   What type of user do you wish to add? a) Management User (mgmt-users.properties) b) Application User (application-users.properties) (a): b

   Enter the details of the new user to add. Realm (ApplicationRealm) : Username : ejb Password : Re-enter Password : What roles do you want this user to belong to? (Please enter a comma separated list, or leave blank for none)[ ]: About to add user 'ejb' for realm 'ApplicationRealm' Is this correct yes/no? yes Added user 'ejb' to file '/home/local/SPSSIT/milad/jboss-eap-6.1-slave/standalone/configuration/application-users.properties' Added user 'ejb' to file '/home/local/SPSSIT/milad/jboss-eap-6.1-slave/domain/configuration/application-users.properties' Added user 'ejb' with roles to file '/home/local/SPSSIT/milad/jboss-eap-6.1-slave/standalone/configuration/application-roles.properties' Added user 'ejb' with roles to file '/home/local/SPSSIT/milad/jboss-eap-6.1-slave/domain/configuration/application-roles.properties' Is this new user going to be used for one AS process to connect to another AS process? e.g. for a slave host controller connecting to the master or for a Remoting connection for server to server EJB calls. yes/no? no milad@linux-pc-0018:~/jboss-eap-6.1-slave$ bin/standalone.sh -server-config=standalone-full-slave.xml -Djboss.socket.binding.port-offset=100 -Djboss.node.name=slave

3. Start up MASTER:

   milad@linux-pc-0018:/jboss-eap-6.1$ export JBOSS_HOME=/home/local/SPSSIT/milad/jboss-eap-6.1 milad@linux-pc-0018:/jboss-eap-6.1$ bin/standalone.sh -server-config=standalone-full-master.xml -Djboss.node.name=master

If now I navigate to URL http://localhost:8080/movie/ (points at the MASTER instance) and enter "a scanner darkly" in the input text, the movie is correctly found, and I see the Hibernate query run on the SLAVE.

The two descriptors {{standalone-full-master.xml}} and {{standalone-full-slave.xml}} have been produced from the original {{standalone-full.xml}}, and:

• adding the MySql datasource to both,
• adding the securiry/remoting information (following server-to-server guide) to the MASTER's only.
