Camunda @bpmNEXT 2013

bpmNEXT has definitely been a Home Run, as Bruce Silver puts it. Bruce has impressively succeeded in creating a real think tank event for BPM thought leaders sharing their ideas, visions and quite a lot of crazy new stuff around BPM. For those of you who do not know him: Bruce Silver is the BPMN Guru in the US, and I really admire him for both his competence and all that he has done for the standard. Rest assured that a good deal of BPMN’s amazing success is due to him. That said, it should not be surprising how excited I was when discovering in his Review Post a comment about my presentation of Camunda Cycle, one of the numerous…

A closer look at the Camunda Modeler

Along with the launch of our open-source BPM platform we made the Camunda Modeler available to the public, both as a software and as source code. With the Camunda Modeler, you get at free modeling tool that integrates in your Eclipse IDE and focuses on seamless modeling of process and collaboration diagrams. We invite you to try out the modeler, give us feedback and contribute to it. Present, past and Future The Camunda Modeler is based on the Eclipse BPMN 2.0 Modeler that integrates into the Eclipse IDE. Its aim was to allow users with technical focus to create BPMN 2.0 diagrams and maintain BPMN and Camunda BPM / Activiti specific attributes in those diagrams. Beginning October 2012, we decided to dedicate bigger long term efforts to…

The HTML5 parts in Camunda BPM

The Camunda bpm stacks currently includes three web apps: cycle, cockpit, Tasklist. All of them are rewrites from a JSF 2.0 ancestor version and with this post I want to explain the decision to built them on a HTML5 plus REST architecture and not with <insert java web framework here>. Its clear that the web itself is based on the client-server principle. Many Web frameworks like JSF, Vaadin etc. implement it like this: Provide a abstraction layer to define the HTML + JS + CSS Code to generate (Java Code, Facelets etc.) which in the end is your application On request, generate the code sent to the browser, initially create a session model for data binding etc. Keep the generated browser client…

A look at the fresh REST API

Camunda BPM comes with a fresh REST API based on JAX-RS. Its goal is to expose the process engine services as broadly as possible. That means we aim to enable you to interact with process engine services via REST with similar expressiveness as in plain Java. With 7.0.0-alpha1, we provide methods such as task querying that already realize our desired degree of detail (similar for process definitions and instances). For future releases, we plan to broaden the scope to reach the afore-mentioned goal. Use it with a prebuilt distro In 7.0.0-alpha1 the API covers interactions with process definitions, process instances and tasks as documented on camunda.org. Enough to build your first process applications as demonstrated in Camunda’s Tasklist. In our…

Camunda forks Activiti and launches Camunda BPM

I am proud to announce that today Camunda launches a new open source BPM project: Camunda BPM. At this juncture we part ways with the Activiti project which we have contributed to since the first days. Leaving Activiti is a sad but necessary step for us. Starting as a consulting company, we have built a customer base of 250+ in little over 4 years. Last year, we entered the BPM vendor business with the Camunda fox BPM platform. Our success and the positive feedback we got from customers made us realize that we have to go all-in. Today, we drop the “fox”-brand and as Camunda BPM, we embark on the journey of building the best BPM platform, under our own leadership & vision. We…

Where is the “retry” in BPMN 2.0?

This blog was originally published in 2012 and updated in April 2021 by Nele Uhlemann In a famous article, Gregor Hohpe describes four strategies for dealing with failures in a business transaction: How does BPMN 2.0 and Camunda Platform deal with such problems and exceptions? Here are some experiments I made. Compensation In BPMN 2.0 we can model compensation explicitly: If I detect that I have no milk after making coffee, I throw the coffee away. It is important not to serve coffee without milk, even at the expense of having an unsatisfied customer. By the way, using compensations is a powerful way to roll back Sagas. More about Sagas in the following paragraph. The Saga Pattern instead of a…
