Update a JBoss EAP 6 or Wildfly / JBoss EAP 7 Installation from 7.16 to 7.17

The following steps describe how to update the Camunda artifacts on a JBoss EAP 6 or Wildfly / JBoss EAP 7 in a shared process engine scenario. Throughout the procedure, refer to the update guide.

If not already done, download the Camunda 7.17 JBoss distribution or Camunda 7.17 Wildfly distribution. In the following instructions, $APP_SERVER should be replaced with either jboss or wildfly, depending on the used application server.

The update procedure takes the following steps:

  1. Update the Camunda 7 modules.
  2. Update optional Camunda 7 modules.
  3. Update Camunda web applications.

Whenever the instructions are to replace a module, delete the previous version of the module first to avoid orphan jars.

  2. Download the REST API web application archive from our Artifact Repository. Alternatively, switch to the private repository for the enterprise version (credentials from license required). Choose the correct version named $PLATFORM_VERSION/camunda-engine-rest-$PLATFORM_VERSION-$CLASSIFIER.war.
  3. Deploy the web application archive to your JBoss/Wildfly instance.

Update Cockpit, Tasklist, and Admin

The following steps are required to update the Camunda web applications Cockpit, Tasklist, and Admin on a JBoss/Wildfly instance:

  1. Undeploy an existing web application with a name like camunda-webapp.
  2. Download the Camunda web application archive from our Artifact Repository. Alternatively, switch to the private repository for the enterprise version (credentials from license required). Choose the correct version named $PLATFORM_VERSION/camunda-webapp-jboss.war.
  3. Deploy the web application archive to your JBoss/Wildfly instance.
