Imixs Software Solutions GmbH presents with the Open Source project “Imixs Workflow” a Business Process Management (BPM) solution for Glassfish and JBoss Application Servers. Glassfish and JBoss are open source application servers based on the Java EE specification. These server platforms are widely-used by a lot of small and medium companies. The Imixs JEE Workflow components can be seamlessly integrated into Glassfish 2.1, 3.0 and JBoss 5.0 and 6.0 infrastructure. Thus the project provides a highly scalable and robust BPM solution. The Imixs workflow project makes use from the powerful component framework provided by the Java EE specification. All Imixs Workflow Java EE components are implemented as Enterprise Session and Entity EJBs. This makes it very easy to integrate these components in a new or existing enterprise software project.

THE ADVANTAGE OF BPM SOLUTIONS BASED ON JAVA EE
One of the most important advantages of the Imixs Workflow Engine is the fact that Imixs Workflow is based on the Java Enterprise Plattform (Java EE). A Java EE application server can handle transactions, security, scalability, concurrency and management of the components that are deployed to it. So all the features and characteristic from the Java EE plattform are also part of Imixs Workflow. Here are some examples: Continue reading “THE ADVANTAGE OF BPM SOLUTIONS BASED ON JAVA EE”
BPM AND JSF
Today I added a new example page illustrating how to integrate the Imixs JEE components into a JSF application. As the Imixs Workflow project provides a full featured Workflow Management Systembased on EJB and JSF components, it’s not so difficult to extend a JSF application with BPM functionality.

MODELER HELP UPDATED
The Imixs Modeler Documentation is updated and some addtional Informations about the usage were added to the site. The Imixs Workflow Modeler is a good starting point to begin a BPM Project.

SWITCHING JDK FOR GLASSFISH APPLICATION SERVER
Since the latest Imixs Workflow release 2.1.0 we recommend to run Imixs Workflow Applications on Glassfish Application Server using JDK 1.6.
If you use Linux Debian as your Server platform – which is a nice choice – the upgrade from JDK 1.5 to JDK 1.6 is a little bit tricky. So make sure to pay attention to the following points:
- Java 1.6 for debian 4 (etch) is available in backports, so just add backports.org to sources.list:
>vi /etc/apt/sources.list
and add the following line to the list of repositories:
deb http://www.backports.org/debian etch-backports main contrib non-free - Next you can install the JDK 1.6 with following command
>aptitude update
>aptitude -t etch-backports install sun-java6-jdk - Now you be able to switch to the new java version using the following command:
>update-alternatives –config java
You will see an output like this:
There are 2 choices for the alternative java (providing /usr/bin/java). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/lib/jvm/java-6-sun/jre/bin/java 63 auto mode 1 /usr/lib/jvm/java-1.5.0-sun/jre/bin/java 53 manual mode * 2 /usr/lib/jvm/java-6-sun/jre/bin/java 63 manual mode Press enter to keep the current choice[*], or type selection number:
now you can choose the new JDK.
After you have upgraded the Java Version you can check the version number with
>java -version
You should now see something like this:
java version "1.6.0_07" Java(TM) SE Runtime Environment (build 1.6.0_07-b06) Java HotSpot(TM) 64-Bit Server VM (build 10.0-b23, mixed mode)
UPDATE THE GLASSFISH ENVIRONMENT
After you have changed the JDK on your OS you need to change also the JDK setting used by the Glassfish Server.
The JDK which is used to start the Glassfish Server is configured in the file
GLASSFISH_INSTALL/config/asenv.conf
Edit the file with
>vi asenv.conf
and change the line
AS_JAVA="/usr/lib/jvm/java-1.5.0-sun-1.5.0.14/jre/.."
into
AS_JAVA="/usr/lib/jvm/java-6-sun/jre/.."
Now you can restart Glassfish Server which will now run with the new JDK 1.6.
IMIXS WORKFLOW RUNS ON JBOSS APPLICATION SERVER
The Imixs JEE Workflow components are successfully tested on the latest release of JBoss Application Server V 5.1.0.GA (JBossAS 5). The JBoss Application Server is the one of the most widely used Java application servers on the market.
The Imixs JEE Workflow is a full featured Workflow Management System (WFMS) based on the Java EE5 specification and fulfills the requirements to a scalable, transactional, robust and simple deployable Java EE Workflow System.
JBoss 5 for the Java EE5 codebase fully complies with the Java EE5 specification. So the JBossAS 5 is an ideal platform for Workflow Management Systems based on the Imixs Open Source Workflow.
The Imixs JEE Project site provides additional Installation guides for JBoss and also informations about deployment strategies to get best results running the Imixs Worklow on JBoss Application Server.

VERSION 2.1.0 FINAL RELEASED
The latest version 2.1.0 of the Imixs Workflow and the Imixs Java EE Workflow components are now final released! The new version includes a bunch of updates and new features.
Also the 2.1.0 release is now supporting Java EE 6 and is tested with Glassfish V3 Application Server! Therefor the deployment is simplified and now it is much more easy to use the components in your own Java EE project. It’s easy to integrate the Imixs Workflow Engine into your web project and build a scalable, transactional, robust and simple deployable Java EE Workflow System.
Check out the Imixs Workflow and build your business application in a fast and easy way now.
Read more about the project on the Imixs Project site.
Or read the Quick guide how to install the sample application on a Glassfish V3 or Glassfish V2.1 application server.
We also provide a blog with a tutorial to get an overview about the project.
Also components of the Imixs Workflow Project are now provided as Maven artifacts in the central maven repository. This makes it much more easy to use the components in your projects if you are working with maven.
ORACLE-FIX 2.0.1
Running the latest stable release of the Imixs JEE Workflow components (imixs-workflow-jee-impl-2.0.1) on a Oracle database can lead into a situation where users did not find any entities or can process new workitems.
The reason for this issue is a query optimizer used in one of the core EJBs. The Problem did not occur on MySQL Database Pools but on Oracle Database Pools.
To fix this problem please use on oracle based workflow systems the following hot fix release:
imixs-workflow-jee-impl-2.0.1-ORACLE-FIX
This patch is available in the subversion repository in /branches. Please let us know if you have any problems. The bug will be fixed in upcoming new 2.0.2 release. Please see also details at Issue Tracker Issue #55.
RELEASE 2.0.2 – ENHANCED WEB SERVICES
In the upcoming new release 2.0.2 the Imixs JEE Workflow provides – among other things a new Web Service implementation which will become much more flexible. Now as the Imixs XML API is fully based on JAXB the SOAP Web Services and the REST Web Services are separated into web modules. This makes is much more easy to use these interfaces in workflow projects as the deployment strategy has changed. As announced the new release will run on JEE5 (Glassfish 2.1) as also under JEE6 (Glassfish 3). And also the deplyoment becomes more flexible as you are now no longer forced to deploy all web service modules together with your application.
The project documentation will be extended in the near future with an additional section for XML & Web Services.
You can check out the current 2.0.2-SNAPSHOT release from the Subversion repository. See also the new snapshot releases of imixs-workflow-xml, imixs-workflow-rest and imixs-workflow-soap. If you have any comments or questions please post the in the Imixs Forum.
