They are two independent Cases.
The case in eclipse attempts to show: how you should control the Process by Coding (for developer).
The case running in Tomcat (You can use Explore and Probe etc.) attempts to show: how you can use the Activiti by Browser (for end-user).
If you want see some modified on Explorer, you should:
1. Modify the Process Name in FinancialReportProcess.bpmn20.xml in here: activiti-5.0.alpha2\docs\examples\src\org\activiti\examples\bpmn\task
2. Re-Run the ant command: ant demo.setup
3. In your Browser, you can see Process Name has been modified by yourself.
Btw: Pls read the build.xml (178–193) carefully and you will find the secret. Haha.
