Lucene Index Consistency

With the latest version of Imixs-Workflow we support now a consistency Lucene search index coupled with the Java EE container based transaction concept.

Writing a Lucene Index during a Java EE transaction, coupled to JPA database operations, it becomes quickly difficult to keep the Lucene index consistent. The reason is that a lucene index can become inconsistency if you write the lucene index within a long running Java transaction. In case the transaction fails lately, there is no way to roll back the already written lucene index automatically. This is different to the build-in roll-back functionality of a SQL database which is only writing new data in case the transaction succeeds. Also clients reading the index before a running transaction is closed will read uncommitted index data which will lead to wrong search results. Continue reading “Lucene Index Consistency”

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.

You Shouldn’t Manage Your Business Processes With Excel

Why do employees in companies repeatedly use Microsoft Excel or PowerPoint to manage business data and tasks?

Companies today have a variety of business applications in use. Some for legacy reasons, some for strategic reasons and some just because they are hip and make fun. And most of the times, these applications are not enough to cover all aspects of daily working life. A lot of tasks and data that need to be processed on a daily basis are often managed with EXCEL and POWERPOINT. This is not wrong in general and provides employees a way to prepare business figures in tables or display them clearly in a presentation. But often these applications are also abused for a kind of data management. But EXCEL is no database and POWERPOINT is not a messaging tool.  The problem is, that these tools often collect data that is needed to implement certain business processes and for which there is no suitable application available. In a short time, these solutions become indispensable and are passed down from generation to generation.

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.

Imixs-BPMN – Version 1.4.7 Released

The open source project Imixs-BPMN has released version 1.4.7. Besides the integration into the Eclipse platform Oxygen, the new version offers various improvements in modeling business processes based on the BPMN 2.0 standard.

Imixs Workflow is a human centric workflow engine that allows to model and to execute human-2-human business processes. Based on the Eclipse platform, Imixs-BPMN offers a professional and stable platform for modeling within the BPMN 2.0 standard. Both, responsibilities and access rights, as well as individual business rules can be modelled graphically.

Version 1.4.7 now represents business rules – so called ‘ conditions ‘ – and access rights (ACL) in a graphical way. This makes it easier to create process models and control them during the design phase.

In addition, Imixs-BPMN now supports so-called ‘Conditional-Events’ and ‘Split-Events’. The former can be used to model decisions based on business rules. Split-Events support parallelism. Split-Events play an important role for the mapping of audit-safe business processes. These new features increase the transparency of complex processes within an organisation.

Imixs-BPMN is open source and part of the Imixs-Workflow technology. The IMIXS Software Solutions GmbH supports enterprises and organisations in the development and implementation of digital business processes.
