The update procedure takes the following steps:

  • Update the Camunda BPM Modules
  • Update Optional Camunda BPM Modules
  • Update Camunda Web Applications
    Whenever the instructions are to replace a module, make sure to delete the previous version of the module first to avoid orphan jars.

1. Update the Camunda BPM Modules

Replace the following modules from the folder $APP_SERVER_HOME/modules/ with their new versions from the folder :

  • org/camunda/bpm/camunda-engine
  • org/camunda/bpm/$APP_SERVER/camunda-$APP_SERVER-subsystem
  • org/camunda/bpm/model/camunda-bpmn-model
  • org/camunda/bpm/model/camunda-dmn-model
  • org/camunda/bpm/model/camunda-xml-model
  • org/camunda/bpm/dmn/camunda-engine-dmn
  • org/camunda/bpm/dmn/camunda-engine-feel-api
  • org/camunda/bpm/dmn/camunda-engine-feel-juel
  • org/camunda/commons/camunda-commons-logging
  • org/camunda/commons/camunda-commons-typed-values
  • org/camunda/commons/camunda-commons-utils

    2. Update Optional Camunda BPM Modules

In addition to the core modules, there may be optional artifacts in $APP_SERVER_HOME/modules/ for LDAP integration, Camunda Connect, Camunda Spin, and Groovy scripting.If you use any of these extensions, the following update steps apply:

Replace the following module from the folder $APP_SERVER_HOME/modules/ with its new version from the folder $APP_SERVER_DISTRIBUTION/modules/, if present:

  • org/camunda/bpm/identity/camunda-identity-ldap

    Camunda Connect

Replace the following modules from the folder with their new versions from the folder $APP_SERVER_DISTRIBUTION/modules/, if present:

  • org/camunda/connect/camunda-connect-core
  • org/camunda/connect/camunda-connect-http
  • org/camunda/connect/camunda-connect-soap-http
  • org/camunda/bpm/camunda-engine-plugin-connect
  • org/camunda/spin/camunda-spin-core
  • org/camunda/spin/camunda-spin-dataformat-json-jackson
  • org/camunda/spin/camunda-spin-dataformat-xml-dom

  • com/fasterxml/jackson/core/jackson-annotations

  • com/fasterxml/jackson/core/jackson-core
  • com/fasterxml/jackson/core/jackson-databind

Starting from v. 7.9, Camunda BPM is delivered with Spin 1.5.1 version, which in its turn relies on Jackson of v. 2.9.5 (compared to v.2.6.3 used before).

In case you need to stick to older Jackson version (2.6.3):

  • do not replace Jackson modules listed above.
  • Fix the Jackson version in module org/camunda/spin/camunda-spin-dataformat-json-jackson/main/module.xml to be 2.6.3.
    Scenarios, where you could consider using the earlier Jackson version are listed .

Groovy Scripting

Replace the following module from the folder with its new version from the folder $APP_SERVER_DISTRIBUTION/modules/ if present:

  • org/codehaus/groovy/groovy-all

    3. Update Camunda Web Applications

  • Wildfly requires the classifier: wildfly

  • JBoss AS 7 requires the classifier: jbossas7
    Please bear this in mind …

  • on downloading the REST API from our Maven Nexus Server

  • on using the REST API dependency within your custom pom.xml
    The Maven coordinates need to be changed accordingly:

Update REST API

The following steps are required to update the Camunda REST API on a JBoss/Wildfly instance:

  • Undeploy an existing web application with a name like camunda-engine-rest
  • Download the REST API web application archive from our . Alternatively, switch to the private repository forthe enterprise version (credentials from license required). Choose the correct version named $PLATFORM_VERSION/camunda-engine-rest-$PLATFORM_VERSION-$CLASSIFIER.war.
  • Deploy the web application archive to your JBoss/Wildfly instance.

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

  • Undeploy an existing web application with a name like camunda-webapp
  • Download the Camunda web application archive from our Maven Nexus Server.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.
  • Deploy the web application archive to your JBoss/Wildfly instance.
