(2) use PLFM/trunk/tools/tcgaWorkflow/pom.xml as the example for your pom.  You'll want to copy the <dependencies>, <properties>, and <build> sections.  There's a lot of java magic wrapped up in that pom.

(3) if package for the workflow code is not already listed in PLFM/trunk/lib/lib-workflow/src/main/sanity check your new package, every SageBio workflow has the  Hello World workflow embedded in it.  Make sure you can run it from your new package:

• ~/platform/trunk/tools/MyNewWorkflow>java -javaagent:/Users/deflaux/Downloads/aws-java-sdk-1.3.3/third-party/aspectj-1.6/aspectjweaver.jar -cp target/MyNewWorkflow-0.11-SNAPSHOT.jar com.amazonaws.services.simpleworkflow.flow.examples.helloworld.ActivityHost
• ~/platform/trunk/tools/MyNewWorkflow>java -javaagent:/Users/deflaux/Downloads/aws-java-sdk-1.3.3/third-party/aspectj-1.6/aspectjweaver.jar -cp target/MyNewWorkflow-0.11-SNAPSHOT.jar com.amazonaws.services.simpleworkflow.flow.examples.helloworld.WorkflowHost
• java -javaagent:/Users/deflaux/Downloads/aws-java-sdk-1.3.3/third-party/aspectj-1.6/aspectjweaver.jar -cp target/MyNewWorkflow-0.11-SNAPSHOT.jar com.amazonaws.services.simpleworkflow.flow.examples.helloworld.WorkflowExecutionStarter

(4) if the Java package for the workflow code is not already listed in PLFM/trunk/lib/lib-workflow/src/main/resources/META-INF/aop.xml add it there

(45) write your code, at a minimum you will likely want code similar to the following  TODO ADD LINKS AFTER THE MERGE TO TRUNK

• workflow interface: 
• activity interface:
• workflow implementation:
• activity implementation:
• workflow runner (runs the decider):
• activity runner (runs the activities):
• workflow initiator (kicks off workflows): note that this particular example is rather complicated, an initiator could just kick off a single workflow instance
• workflow configuration utility:
• workflow configuration properties:
• workflow configuration properties template:
• workflow test (important this will help you ensure that your Promise variables are configured correctly):

...

This can happen when the activity or workflow code throws a runtime exception such as a NullPointerException.  Unfortunately the unit testing framework provided by SWF does not log them.

"java.lang.IllegalStateException",{"cause":null,"message":"not ready","localizedMessage":"not ready"

Promise Variables were used Incorrectly
