How to send an email when a usertask is assigned

“I don’t want to watch my camunda Tasklist all day. When there is something to do, I want to get an email containing a link that takes me directly to the respective task!” This is a typical statement by process participants (aka business users). There are numerous possible ways to implement such a requirement in your process application, e.g. using a service task: But this is not really appropriate, since it makes the process model rather verbose and therefore less valuable for business-IT-alignment. The more elegant way is to use a task listener: This very powerful concept is described in detail in the userguide, and the behavior we want is a perfect use case, so let’s see how it works!…

camunda BPM: Power to Embedded Taskforms

For everyone out there using embedded task forms in the camunda Tasklist there is great news: The forms are getting way more powerful. The upcoming alpha of camunda 7.1 introduces two extensions for embedded task forms: Client side form validation and form extensions via JavaScript. Form Validation Validation directives provided by AngularJS may now be attached to form fields to activate simple client-side validation constraints for them. The following form field will only accept one of the strings demo, john, mary or peter due to the defined pattern: <input form-field type="string" name="assignee" ng-pattern="/^(demo|john|mary|peter)$<span id="goog_340102718"><span id="goog_340102719">/"</span></span> /> If a user enters an invalid value in a form field the field will be marked as invalid. Additionally the complete task button will be disabled and the form may…

Camunda BPM + Apache Camel: Integrating two Open Source frameworks for a lightweight BPM+SOA infrastructure

Apache Camel is a well known Open Source framework solving a lot of integration problems and implementing the Enterprise Integration Patterns. So combining it with Camunda BPM is a perfect match: solve workflow and BPM requirements with Camunda and integration requirements with Camel. Together with Rafael Cordones we took the existing Activiti Camel Module as a basis and did a huge refactoring. For everybody knowing this module I compiled the changes at the end of this article. For everybody else: Lean back and enjoy the show while I quickly walk you through the features. I do this based on our “camel use cases” example which is available on GitHub (by the way – you can discuss this process model on Camunda share): The…

camunda share: Discuss your BPMN 2.0 process model in the cloud

Once a year the whole camunda team does a ShipIt-Day (inspired by Atlassian) – developing something awesome within 24 hours. This year, Kristin, Falko and me did “camunda share” – a web application in the cloud to share and discuss BPMN 2.0 process models. And we shipped it! It is live. Try it today: https://camunda.org/share/ Why camunda share? We often discuss with colleagues, partners or customers about process models. We often send around annotated PDF files via email. We were tired of it and wanted to have something like doodle for this. And with camunda BPM and especially the camunda-bpmn.js component we had everything at hand to get that going. And we had 24 hours 🙂 The idea is to avoid any…

How to use BPMN 2.0 ScriptTask with Groovy in JBoss

Note: this blogpost only applies to camunda BPM version < 7.1.0. Starting from camunda BPM 7.2.0 we ship Groovy as part of the pre-packaged distribution. Recently at a customer we added a ScriptTask to a process and wanted to run a Groovy script. Pretty easy with camunda BPM – but in the JBoss environment you have to know how to correctly put Groovy on the classpath – as we correctly use the JSR 223 stuff to recognize existing Scripting Languages. To help others and to remind myself I quickly wanted to blog how to do this. 1.) Add groovy module to your JBoss Download latest groovy-all.jar and copy it to JBOSS_HOME/modules/groovy/main/groovy-all.jar. Create JBOSS_HOME/modules/groovy/main/module.xml with the following content: <?xml version="1.0" encoding="UTF-8"?> <module…

camunda BPM participates in BPMN Roundtrip Demo of OMG

The camunda BPM platform participated in a somewhat extreme BPMN roundtrip demo of the OMG. During that demo, the camunda engine managed to execute a BPMN process model that we pushed through five different modeling tools. Altogether, eight tools participated in the entire roundtrip. Among them where camunda Modeler for editing BPMN in Eclipse, the camunda engine for executing the BPMN process and camunda-bpmn.js for rendering BPMN in JavaScript. In addition, I also did a demo of how to use camunda Cycle for automating BPMN roundtrips.
