Update a JBoss/Wildfly Installation from 7.10 to 7.11

The following steps describe how to update the Camunda artifacts on a JBoss AS 7 and Wildfly server in a shared process engine scenario. For the entire procedure, refer to the update guide. If not already done, make sure to download the Camunda BPM 7.11 JBoss distribution or Camunda BPM 7.11 Wildfly distribution. In the following instructions $APP_SERVER should be replaced with either jboss or wildfly, depending on the used application server.

WildFly 8 Modules

From version 7.11, only a single Camunda BPM WildFly distribution is provided, packaged with the latest WildFly version. For WildFly 10+ users, the update guide remains the same. However, if you are a WildFly 8 user, please download the Camunda WildFly 8 Modules archive for updating the Camunda BPM Modules.

Furthermore, the Camunda subsystem extension in the application server’s configuration file (in most cases $WILDFLY_HOME/standalone/configuration/standalone.xml) needs to be adjusted to:

<server xmlns="urn:jboss:domain:2.1">
  <extensions>
    ...
    <extension module="org.camunda.bpm.wildfly.camunda-wildfly8-subsystem"/>

The update procedure takes the following steps:

  1. Update the Camunda BPM Modules
  2. Update Optional Camunda BPM Modules
  3. 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 $APP_SERVER_DISTRIBUTION/modules/:

  • 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-cmmn-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:

LDAP Integration

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 $APP_SERVER_HOME/modules/ 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-client
  • org/camunda/bpm/camunda-engine-plugin-connect

Additionally, also replace the following dependent modules:

  • org/apache/httpcomponents/httpclient
  • org/apache/httpcomponents/httpcore
  • commons-codec/commons-codec

Camunda Spin

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

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

Additionally, also replace the following dependent modules:

  • com/fasterxml/jackson/core/jackson-annotations
  • com/fasterxml/jackson/core/jackson-core
  • com/fasterxml/jackson/core/jackson-databind
  • com/jayway/jsonpath/json-path

3. Update Camunda Web Applications

Update REST API

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

  1. Undeploy an existing web application with a name like camunda-engine-rest
  2. Download the REST API 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 $PLATFORM_VERSION/camunda-engine-rest-$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 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.
  3. Deploy the web application archive to your JBoss/Wildfly instance.
