New Official Extension: camunda-bpm-migration

Written by Malte Sörensen on , under Execution category.
Camunda BPM Migration is a framework for making process instance migration easier. It builds upon the migration functionality introduced in Camunda BPM 7.5. This is a great feature enabling the community to go boldly where few men have gone before ;) Typically, instance migration is avoided like the pest. It’s a pain. This feature, together with the migration extension, aims to ease that pain. What Does the Migration Extension Offer? Before answering that, let’s have a look what Camunda already provides.

Adding Custom Elements to the BPMN Properties Panel

Written by Vinod Louis on , under Modeling category.
Extending the BPMN properties panel to add custom elements. Goal In this article, we will try to add a custom element to the BPMN properties panel under the ‘General’ tab for a service task type component. To be precise, under the ‘General’ tab, in the details sections, if ‘Java Class’ is selected as implementation type, a text box appears below. Here the user is expected to enter the java class, but our goal is to replace the text box with a combo box, where the options are populated externally with JSON/API data.

Camunda BPM Camel 0.5.0 Released - External Task Support

Written by Stephan Pelikan on , under Community category.

The community extension Camunda BPM Camel seamlessly connects Camunda BPM and the intergration framework Apache Camel.

Next to minor changes, the new release adds support for consuming Camunda’s external tasks (introduced in Camunda 7.4.0) in the form of a Camel route endpoint. This is another level of technical decoupling and brings a lot of adventages.

More FEEL for Camunda

Written by Philipp Ossler on , under Community category.

I’m happy to announce the first release of the new community extension FEEL-Scala. FEEL is a part of the DMN specification of the OMG and stands for “Friendly Enough Expression Language”. It provides a simple data model and a syntax designed for a wide audience. The new community extension implements a large feature set of FEEL and replaces the default FEEL engine of the Camunda DMN engine.

Argon2 as password-hashing function in Camunda

Written by Christopher Zell on , under Integration category.
Introduction On the new version of the Camunda Engine Platform (7.7) the user passwords, which are stored in the database, are by default hashed with a SHA-2 family algorithm. Before the passwords are hashed, they are concated with an individual random generated salt for each user, to prevent dictionary and rainbow table attacks. For someone who needs a more secure hashing algorithm Camunda introduce a new API, which allows to customize and exchange the default hashing algorithm.
