Patterns
Default Behavior:
1. New version created in DB upon each change in BPMN XML
2. New process instances start with the latest version
3. Running process instances continue using the version they started
with
It is normal to have multiple process versions in parallel.
Process Versioning
Imagine a Process Application
my-application.war
MyClass.java
task-form.xhtml
some-library.jar
my-process
Process Engine
Container
Add version number to affected artifacts:
Limitations
Doesn’t work for libraries
Complete redesign => Version 2.0
Small Changes: Bugfixes or Minor Feature Additions
my-application.war
MyClass.java
MyClassV2.java
task-form.xhtml
my-process
task-form-v2.xhtml
some-library.jar
Running Multiple Versions in Parallel
my-application-v2.0.war
MyClass.java
task-form.xhtml
some-library-v2.0.jar
my-process-v2.0
my-application-v1.0.war
MyClass.java
task-form.xhtml
some-library-v1.0.jar
my-process-v1.0
Process Engine
Container
JPA, EJB, JTA …
Maven Resource Filtering for getting major and minor version number into BPMN process id (=process definition key)
Process Definition Isolation
Include major and minor version in final name
Class Loader Isolation
Build Helper Plugin to parse version number
Running Multiple Versions in Parallel
Alternative: Multiple Apps register for same Process
my-application-v2.0.war
MyClass.java
task-form.xhtml
some-library-v2.0.jar
my-process
my-application-v1.0.war
MyClass.java
task-form.xhtml
some-library-v1.0.jar
my-process
Process Engine
Container
JPA, EJB, JTA …
<process id="my-process" version="1.0" …
Process Application registers for selected Process Versions
@ProcessApplication
public class MyProcessAppliaction extends EjbProcessApplication {
@PostDeploy
public void registerProcessApplication(
ProcessEngine processEngine,
ProcessApplicationInfo processApplicationInfo
){
// Find Process Version based on XML attribute
…
// Register Process Archive for Process Version
processEngine.getManagementService()
.registerProcessApplication(
processDefinitionDeploymentId,
processApplicationReference);
}
}
<process id="my-process" version="1.0" …
