Imixs-Workflow – Version 5.0.2 Released

Today we released version 5.0.2 of the Open Source Workflow Engine Imixs-Workflow.

The new release includes – beside the general new support of Eclipse Microprofile – some important new features. The main feature of this release is a new implementation of Imixs Adapter API. This API supports now two kinds of adapter interfaces.

  • The SignalAdapter can be used to implement a fine grained control of the event processing life cycle.
  • The GenericAdapter interface provides a model independent extension point to implement generic API features.

One of the first implementations is the new AccessAdapter class. This adapter controls the ACL defined by the Imixs-BPMN Model definition. This adapter can also be a good starting point of custom generic adapters.

Together with the Imixs Plugin API the Adapter API now provides developers with a strong and flexible extension mechanism to implement all kind of human-centric and microservice based workflow applications.

Imixs-Workflow Version 4.4.4

Imixs-Workflow Version 4.4.4 is now released! The latest version includes two important improvements and shows a much better performance.

  • LuceneSearchService – Flush Event Log
    This improvement solved an issue with overrun Lucene Event Logs. Tests showed that the latest version runs stable and with better performance.
  • BPMN: Conditional Events
    BPMN models, using conditional events, can now be parsed correctly even if the model contains standard BPMN elements between an event and the condition:

The most important improvement of version 4.4 was the transaction support of Lucene event logs. With version 4.4.4 of Imixs-Workflow, this feature is now stable and shows also a very good performance in long running transactions.

Imixs-Workflow Version 4.4 Released

Today we released our new Version 4.4 of Imixs-Workflow. The new release 4.4.0 includes new features, several bug fixes and minor enhancements of the Imixs-Workflow API.

The most important new feature is the Lucene Index which is now supporting transnational Read Committed. In the past, after a transaction was roll backed, in some situations the lucene index contains uncommitted entries, which leads to unexpected search results. With the new version 4.4 a complete re-implementation of the Lucene UpdateService has been realized. The indexer is now more robust and reflects only committed transactions. 

Another new feature is the GenericSchedulerService. This new service interface can be used to implement custom schedulers. The implementation of such a scheduler is now quite easy and the scheduler is automatically managed by the new SchedulerService EJB.  In the next releases we will re-implement also the existing WorkflowScheduler.

Generate and Export SEPA Files with a Workflow Engine

The Imixs-Workflow project now supports the generation of SEPA files. The Single Euro Payments Area (SEPA) is a payment-integration initiative of the European Union for simplification of bank transfers denominated in euro. Imixs-Workflow started the new adapter project Imixs-SEPA-Adapter to simplify the SEPA integration in any kind of finance workflow. The project provides a new scheduler service to generate SEPA files on a daily basis. For example this adapter can be used to export the results of an invoice approval process into a SEPA file which can be used in any payment software.

Free and Flexible Adaptability

The Imixs-SEPA-Adapter is based on BPMN 2.0 and the Imixs-Report functionality to allows a free adaptability of the SEPA export to any custom workflow project. This adaptability is important because invoicing workflows differ from company to company. The adapter integrates seamlessly into an existing process and can be realized with a standard or a custom workflow mode based on the BPMN 2.0 standard.

 

The SEPA file generated by the adapter can be distributed into the task list of the companies finance team or sent via E-Mail notifications. For security reasons the distribution via the task list is recommended as this fully utilize the strict access concepts of Imixs-Workflow.

Detailed information about the adapter project can be found on Github. The project is in continuous development and contributions from the community are welcome at any time.

First MVC 1.0 Workflow App

Within the Imixs-Workflow project we started our first sample application based on the new Jakarta EE web framework MVC 1.0. The sample application demonstrates how an Imixs-Workflow application can be build with MVC 1.0.

The interesting thing here is that you only need a few lines of code to get the full functionality of a human-centric workflow engine. This is possible because in addition to the existing Jax-rs Rest API, the Imixs-Workflow engine provides services which can be easily adapted by the core concepts of an MVC-Application.

Imixs-BPMN for Eclipse Oxygen

With the new version 1.8, Imixs-BPMN is now available for all current Eclipse platforms and also fully integrated into the latest version of Eclipse Oxygen.

Imixs-BPMN in  based on the Open Source BPMN modelling tooling for Eclipse Oxygen, which is currently available in version 1.4.3. See the Eclipse BPMN Homepage for what’s new. The current version 1.8 of Imixs-BPMN can be installed from here.

Imixs-BPMN takes the full advantage of all the capabilities from the BPMN 2.0 standard and complements them with the requirements to a modern workflow management system. Imixs-BPMN enhances the Eclipse BPMN2 modelling Framework with the aspects of a human-centric workflow model executable on the Imixs-Workflow Engine.

The Imixs-Workflow engine provides a set of modern Java Enterprise Services to create and manage process instances based on a BPMN 2.0 definition. The Imixs-Workflow engine can be embedded into a Java Enterprise application as well be deployed into a Microservice Architecture as a Docker Container. See the Imixs-Microservice Project for more details.

Also for older versions of the Eclipse Platforms (Eclipse Mars, Eclipse Neon) Imixs-BPMN is still are available.

New Workflow Rest API

With the next minor release 4.3. of Imixs-Workflow, which will be released shortly, the Open Source Workflow Engine supports a new Rest API. The new API is easier to apply. The result data output is mashed and  now always the same structure. This makes client implementations cleaner and easier to implement. At the same time, all functions of the human-centric workflow engine can be used via one common Rest API.

The old API is also still supported by the Imixs-Workflow engine. The old API can be used with the version prafix /v40/ in the request path.
