How to Set-Up jBPM 6.5.0.Final (on WildFly 10.1.0.Final) Development Environment in Eclipse Neon

In this tutorial we are going to see how to set up jBPM 6.5.0.Final development environment locally. jBPM team did a excellent job by providing a complete jBPM 6.5.0.Final environment for you to just download and extract the jBPM 6.5.0.Final-installer-full.zip bundle and run the ant script, ant will take care of all the installation task for you...sounds interesting, please checkout jBPM document for further details. I highly recommend you to use the automated (ant script) jbpm-installer bundle provided by jBPM team.
For others those who prefer the manual installation, then proceed with the rest of the document.
Please download the following software in your local machine.....

• WildFly 10.1.0.Final
• jBPM Workbench kie-wb
• jBPM dashboard
• jBPM kie-server
• Java JDK 8
• Eclipse Neon
• GEF-SDK update site
• MySQL 5.6
• Maven 3.3.9

kie-wb is a web based workbench or console, dashboard is for building business dashboards and reports and kie-server is the runtime execution server. All of these three components are web applications (war), it can be deploy into any java enabled server like IBM WebSphere, Oracle WebLogic, WildFly, Red Hat JBoss EAP and Apache Tomcat etc.

jBPM-6.5.0.Final on WildFly-10.1.0.Final integrated with Eclipse Neon development Environment

You have two options for developer process development environment, you can use kie workbench(kie-wb) or IDE like eclipse or JBoss developer studio for process development, also you can combine these two options (above diagram) for your convenience.

jBPM uses the JPA 2 to allow users to config whatever the datasource you want to use to persist runtime data. Out of the box jBPM uses h2 java SQL database for persisting runtime data. In this demo we use MySQL database for jBPM.

In my environment RHEL 7 is my operating system, you can use CentOS 7 alternatively if you don't have RHEL 7 installed.

6.0 Install KIE Workbench (kie-wb) on WildFly 10.1.0.Final Application Server and configuration

6.1 Download jBPM workbench (kie-wb) and rename to downloaded war file into kie-wb.war

[root@localhost jbpm]# wget https://repository.jboss.org/nexus/content/groups/public-jboss/org/kie/kie-wb-distribution-wars/6.5.0.Final/kie-wb-distribution-wars-6.5.0.Final-wildfly10.war

6.1 Unpack the war file in a temp folder, 

navigate to SERVER_HOME/standalone/deployments/business-central.war/WEB-INF

6.2 Open jboss-deployment-structure.xml and add the following line

<module name="com.mysqldatabase.mysql" export="true" services="import" meta-inf="import"/>

6.3 Move to SERVER_HOME/standalone/deployments/business-central.war/WEB-INF/classes/META-INF

6.4 Open persistence.xml, update the datasource name, make sure this is the same name you created in the standalone-full.xml datasource name

<jta-data-source>java:jboss/datasources/jbpmDS</jta-data-source>

6.5 Replace the default h2 dialect information with the following code

<properties>

<property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>
...

</properties>

6.7 Now re-create the war file (repack) from the unpacked , modified files,
                                  jar -cvf kie-wb *

 6.8 Navigate to Wildfly 10.1.0.Final/standalone/deployment folder,

6.9 Copy the created kie-wb.war and paste into deployment folder

7.0 Install dashboard on WildFly 10.1.0.Final Application Server and configuration

7.1 Download dashboard

[root@localhost jbpm]# wget https://repository.jboss.org/nexus/content/groups/public-jboss/org/jbpm/dashboard/jbpm-dashboard-distributions/6.5.0.Final/jbpm-dashboard-distributions-6.5.0.Final-wildfly10.war

7.2 Rename the downloaded war file into dashboard.war
7.1 Move to SERVER_HOME/standalone/deployments/dashbuilder.war/WEB-INF

6.7 Open jboss-deployment-structure.xml and add the the following code..

<deployment>

  <dependencies>

<module name="com.mysqldatabase.mysql" export="true" services="import" meta-inf="import"/>

….

…..

 </dependencies>

<deployment>

6.8 Open jboss-web.xml and update the jndi name, make sure this is the same name you created in the standalone.xml datasource name in step6 ...

<jndi-name>java:jboss/datasources/jbpmDS</jndi-name>

6.9 Make sure you save those above mentioned files as you modified.

6.10 Now, navigate to your Server_Home/standalone.configuration folder and open standalone-full.xml file and update the system properties as follows..what we are trying to do here is , jBPM by default creates the those git and kie repo in server bin folder, but maintenance purpose we are moving out of the server and store in in user home.

<system-properties>

<property name="org.kie.demo" value="${org.kie.demo:false}"/>

<property name="org.kie.example" value="${org.kie.example:false}"/>

<property name="org.uberfire.nio.git.dir" value="/home/psin/jbpmrepo" />

<property name="org.uberfire.metadata.index.dir" value="/home/username1/jbpmrepo" />

<property name="org.guvnor.m2repo.dir" value="/home/username/jbpmrepo" />

</system-properties>

6.11 At this point your are done with all the settings, this is the time to test your installation

6.12 Navigate to SERVER_HOME/bin/ folder, type the following command to start the WildFly sever in standalone-full mode

SERVER_HOME/bin/./standalone.sh – c standalone-full.xml

6.13 Open your browser and enter the following url..

             http://localhost:8080/kie-wb/

6.14 Enter user Id/ Password

7.0 Integrating eclipse neon with jBPM Workbench (kie-wb)

Log in to kie workbench (kie-wb) and create a sample jbpm project, build and deploy.Open your eclipse neon IDE, clone the git repository from kie-wb workbench. From the cloned git repo, import the git project into java workspace, since git is version control system, you can able to check-out, edit save and check-in into git. Those modification will be updated in kie-wb. Modification done in kie-wb side will be available in eclipse vice versa.
