batch-job-processor

This project demonstrates the features of JavaEE 7 batch processing API.
The use case is to send SMS/Email notification on daily basis to some particular group of users.

Technology Stack

• JavaEE 7
• EJBs
• CDI
• WildFly 10
• MySQL

Project Setup

• Download/clone the project.
• Execute the attached scripts

• Create datasource in standalone.xml of WildFly server as follows:

    <datasource jndi-name="java:jboss/jdbc/batch-ds" pool-name="BatchDatasource">
        <connection-url>jdbc//localhost:3306/batch?useSSL=false</connection-url>
        <driver>mysql</driver>
        <pool>
            <min-pool-size>10</min-pool-size>
            <max-pool-size>20</max-pool-size>
            <prefill>true</prefill>
        </pool>
        <security>
            <user-name>root</user-name>
            <password>root</password>
        </security>
    </datasource>

• To make job repository persistent, replace the jberet subsystem with the following:

    <subsystem xmlns="urndomain1.0">
        <default-job-repository name="jdbc"></default-job-repository>
        <default-thread-pool name="batch"></default-thread-pool>
        <job-repository name="in-memory">
            <in-memory></in-memory>
        </job-repository>
        <job-repository name="jdbc">
            <jdbc data-source="BatchDatasource"></jdbc>
        </job-repository>
        <thread-pool name="batch">
            <max-threads count="10"></max-threads>
            <keepalive-time time="30" unit="seconds"></keepalive-time>
        </thread-pool>
    </subsystem>

Build the project using:

$ mvn clean install

Deploy the war in wildfly and start the server using:

$ standalone.bat (or standalone.sh)

Open browser and go to URL:

http://localhost:8080/batch

This will open up index.jsp page. Click on the link to start the job.
