Hi all, hi support,

I tested the 2 projects found under this links:

wiki.eclipse.org/Stardust/Knowledge_Base/Testing/Standalone_Spring
wiki.eclipse.org/Stardust/KnowledgeBase/Testing/HowToTest

In the Standalone project, I ran with success the JUnit test.
Now, i would want make the steps below:
-create a standalone engine (running without tomcat server) using the libraries of stardust 2.1.0
-deploy the engine as jar file
-the engine accepts as parameter an xpdl file and entry values for the model activities

The HowToTest project accept entry values, but when i run the project, it finish with errors...
The libraries versions seem obsolete.

Is there an example of a recent project for creating a standalone project with previous steps ?
Where i can found help to do this ?

Thanks very much for your help.

Best regards

Hi Manu,

Stardust 2.1.0 also contains a first version of what is supposed to become an official framework for bootstrapping a Stardust engine as port of your functional tests. The artifact is called "stardust-engine-test" and it allows you to include the bootstrapping of an IPP Spring context in your JUnit tests via rule annotations, for example:

@ClassRule
public static final TestClassSetup testClassSetup = new TestClassSetup(new UsernamePasswordPair("motu", "motu"), ForkingServiceMode.JMS, "MyModel");

As I said, Stardust 2.1.0 contains a very early version of this and we're going to add documentation and more functionality in the next Stardust release, but if you're interested, this is the dependency:

<dependency>
   <groupId>org.eclipse.stardust.engine</groupId>
   <artifactId>stardust-engine-test</artifactId>
</dependency>

Hi,

can you clarify this a bit more?
There is no "Trigger" type with that name in Stardust for modelling, so I assume you mean starting the process via an API call from a Spring bean?

Thanks,

Jan

Hi,

OK. So we're not talking about the use case inside a test case anymore. You're looking for a way to start a process instance ... but I'm still not sure about the exact requirements.
When you say "custom task listener in activity", what do you mean? When you have a task / activity instance then a process instance must already exist.
Do you intend to start another process instance while the user is working on a task? Or do you need to correlate an external event to complete an activity and then drive the process forward?

Hi,

Please see the Service Bus Handbook as the main starting point. It describes the integration with the Apache Camel layer which allows you to route external events from anywhere (see Camel components: http://camel.apache.org/components.html) to the Stardust engine.

The chapters that would cover what you're looking for are:
1. Camel Triggers to start a process:
http://help.eclipse.org/luna/topic/org.eclipse.stardust.docs.camel/html/camel/camel-triggers.htm
2. Camel Applications (using 'Receive' mode) to correlate events to existing processes that are in a waiting (hibernated) state:
http://help.eclipse.org/luna/topic/org.eclipse.stardust.docs.camel/html/camel/camel-application-type.htm

The Camel Trigger and Camel Application Type are shortcuts in the modeler for the functionality provided by Stardust's own Camel component under the hood. For a more advanced reading on the capabilities of this component please see:
http://help.eclipse.org/luna/topic/org.eclipse.stardust.docs.camel/html/camel/camel-ipp-component.html

Best regards,
Jan
