How to specify a custom task worker thread pool for the specific web application in JBoss EAP 7/8

Environment

• Red Hat JBoss Enterprise Application Platform (EAP)
  • 7.x
  • 8.x

Issue

• How do I specify a custom task worker thread pool for the specific web application in JBoss EAP 7 or EAP 8?
• I would like to separate task worker thread pool for each web application. I know I can configure multiple task worker thread pools in IO subsystem. How do I specify the specific web application to use the task worker thread pool?

Resolution

You can specify <executor-name> in your WEB-INF/jboss-web.xml to configure your application to use a specific task worker thread pool instead of the default task worker thread pool.

For example, configure a new task worker thread pool named custom-worker in the io subsystem in your standalone.xml:

        <subsystem xmlns="urn:jboss:domain:io:3.0">
            <worker name="default"/>
            <worker name="custom-worker"/>
            <buffer-pool name="default"/>
        </subsystem>

then you can add WEB-INF/jboss-web.xml in your application war and specify <executor-name>custom-worker</executor-name> like the following:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
    <executor-name>custom-worker</executor-name>
</jboss-web>
