__Part II:__ [Integrating jBPM into AppFuse - Part Deux] - A HowTo for enhancing jBPM Support into AppFuse.
__Part I:__ [Integrating jBPM into AppFuse] - Integrate jBPM Support (via Spring-Modules) into AppFuse.\\
__Part II:__ [Integrating jBPM into AppFuse Part Deux] - Setup AppFuse/jBPM in Eclipse, model defintions using the Jbpm Process Designer.\\
__Part III:__ [Integrating jBPM into AppFuse Part Trois] - Enhance defintions to support tasks, users, schedule and injecting spring beans into actions (Under Construction).\\
At line 5 changed 1 line.
This tutorial is a continuation from [Integrating jBPM into AppFuse]. Please refer to the previous tutorial to complete your basic configuration. In this tutorial we will expand into writing real-world like process defintions, overview of the various jBPM services (persistence, schedule, logging etc) and injecting spring beans into actions. We will also address the issue of redeploying process defintions across server restarts.
This is the 2nd tutorial of a 3 part series. The tutorial covers how to setup AppFuse/Jbpm in Eclipse and model definitions using the Jbpm Process Designer. Before proceeding further please have your basic configuration setup from Part I.\\

* [5] Create and load identities into jBPM database
* [6] Enhance Process Defintion by creating and assigning tasks
* [7] Write test case to validate Process Definition execution
* [8] Enhance Process Defintion by creating ActionHandlers (DecisionHandler)
* [9] Write test case to validate new Process Definition execution
* [10] Wire spring beans inside jBPM Actions
* [11] Test spring bean execution

Before we dive into creating process definitions with the new tool lets create some packages where we will save our process defintions and actions.
Before creating process definitions lets create a package where we will save our process defintions.
At line 29 changed 4 lines.
Create the following packages:\\
{{org.appfuse.jbpm.process}} - will contain process defintions\\
{{org.appfuse.jbpm.action}} - will contain jbpm actions\\
{{org.appfuse.jbpm.ant}} - will contain ant tasks (such as loading identities, cleaning schema, etc)\\
Create the following package:\\
{{org.appfuse.jbpm.process}}\\

Congratulations you have created a process definition using the process design tool!

Let's write a test case to validate our process definition.

We have already written a test case in the [previous article|IntegratingJBPMIntoAppFuse], so go ahead and create {{ProcessTest.java}} class under {{test/dao/org/appfuse/jbpm/dao}} and copy the code from the previous installment with the following modifications:\\

;:%%(color: blue)''For production usage it is not ideal to redeploy process definitions on every startup. Once you have played around with your process defintions and are quite certain they will not change. You can apply the following patch to have the JbpmConfiguration not deploy a process definition every time you restart, rather have it redeployed only if the processdefinition.xml on the file system is out of sync with the database version''%%

Create {{{CustomLocalJbpmConfigurationFactoryBean.java}}} in {{{org/appfuse/jbpm/config}}} and copy code from [CustomLocalJbpmConfigurationFactoryBean.java] into it.
Create the following package:\\

Create {{ CustomLocalJbpmConfigurationFactoryBean.java }} in above package and copy code from [CustomLocalJbpmConfigurationFactoryBean.java] into it.\\
Voila! When you restart the server the process defintion wont be redeployed.
