Instructions

  • Create a directory called demo somewhere convenient on your file system.

  • Unzip EAP into this directory so you have the folder demo/jboss-eap-7.0.

  • Create a management user by running jboss-eap-7.0/bin/add-user.sh, username/password should be admin/admin

  • Similarly unzip Data Grid into the demo directory so you have the folder demo/jboss-datagrid-7.1.0-server.

  • Create a management user by running jboss-datagrid-7.1.0-server/bin/add-user.sh, username/password should be admin/admin

  • Clone this repository in the demo directory so you have the folder demo/jdg7_demo

  • Configure the distributed tasks cache in jboss-datagrid-7.1.0-server/domain/configuration/domain.xml. Look for the stanza:

<subsystem xmlns="urn:infinispan:server:core:8.4" default-cache-container="clustered">
    <cache-container name="clustered" default-cache="default" statistics="true">
        <transport lock-timeout="60000"/>
        <global-state/>
        <distributed-cache-configuration name="transactional">
            <transaction mode="NON_XA" locking="PESSIMISTIC"/>
        </distributed-cache-configuration>
        ...

At the end of the list of caches, add a new cache as follows:

<distributed-cache name="tasks" statistics="true" owners="2" remote-timeout="30000" start="EAGER">
    <locking isolation="NONE" acquire-timeout="30000" concurrency-level="1000" striping="false"/>
    <transaction mode="NONE"/>
</distributed-cache>
  • Start JDG in domain mode which will start two servers automatically:
bin/domain.sh

  • Go into the management console at http://localhost:9990 and make sure that the tasks cache is shown

  • Start EAP as per below, note we start EAP with a port offset of a 1000 so ports don't conflict with JDG:

jboss-eap-7.0/bin/standalone.sh -b 127.0.0.1 -bmanagement=127.0.0.1 -Djboss.socket.binding.port-offset=1000

  • Change into the jdg7_demo and build and deploy the application with mvn clean package wildfly:deploy

  • Run the demo in a browser at http://localhost:9080/jdgdemo
