KIE Server OptaPlanner Task Assignment

An example of assigning tasks on KIE Server using OptaPlanner.

Requirements JDK 1.8 or above Maven 3.0+ node.js 8.12+ npm 6.4.1+ WildFly KIE Server war file from OptaPlanner website (Execution server -> Any application server, unzip to find the war file) Running the demo First start a WildFly instance and deploy KIE artifacts: Download and unzip the WildFly distribution. Let’s call the root of the distribution WILDFLY_HOME. This directory is named after the WildFly version, so for example wildfly-15.0.1.Final is the one we're using for this demo. Download kie-server-...-ee7.war and place it into WILDFLY_HOME/standalone/deployments as kie-server.war. Configure user(s) and role(s). Execute the following command WILDFLY_HOME/bin/add-user.sh -a -u 'kieserver' -p 'kieserver1!' -ro 'kie-server'. You can of course choose different username and password, just make sure that the user has role kie-server Start the server by running WILDFLY_HOME/bin/standalone.sh -c standalone-full.xml. The default URI for KIE Server is http://localhost:8080/kie-server/services/rest/server. Check this location in a web browser to verify the server is running. You will be prompted to type in username and password, use the ones you chose when adding a new user. Now that the KIE Server is running, let's deploy an OptaPlanner service to solve a task assignment problem. Copy the OptaPlanner service kjar to your local mvn repository, this can be done by typing the command mvn install in kie-server-optaplanner-task-assignment/task-assignment-kjar. Run the UI: Go to kie-server-optaplanner-task-assignment/task-assignment-ui npm install to install the dependencies. npm start this will start the frontend application. If it doesn't open in a default browser, open your favorite browser and go to localhost:3000 tl;dr build the kjar:

cd task-assignment-kjar mvn install Run the kie server:

cp kie-server-...-ee7.war WILDFLY_HOME/standalone/deployments/kie-server.war WILDFLY_HOME/bin/add-user.sh -a -u 'kieserver' -p 'kieserver1!' -ro 'kie-server' WILDFLY_HOME/bin/standalone.sh -c standalone-full.xml Run the UI:

cd task-assignment-ui npm install npm start Developing Drools and jBPM
