How to..? - Setup jBPM6 vs jBPM5.4

I’m a newbie in jBPM, Drools etc. I’m using Windows 7, Java 6u43 so far.

I downloaded the jBPM 5.4 Full Installer and tried the demo installation from Chapter 3. Everything went fine – except downloading eclipse-java-helios-SR2-win32.zip, which I could fix easily.

I tried the same with jBPM6. I downloaded the whole stuff from https://hudson.jboss.org/jenkins/job/jBPM/lastSuccessfulBuild/artifact/jbpm-distribution/target/ today.
I used the "jbpm-6.0.0-SNAPSHOT-installer.zip" und tried the demo. Again I had to fix two downloads, again no problems.
But when running the demo like in screencast linked Chapter 3.4, I went into the following problem:
After debugging the main method and opening the [Human Task View], I entered the [UserId] krisv and pressed [Refresh], but I got the following dialog
“Could not connect to task server: 127.0.0.1 [port 5153] transport HornetQ”

I’m sure, something is missing in the installation, but I’m lost in finding the missing part!

Can you please tell me, which additionally components to the "jbpm-6.0.0-SNAPSHOT-installer.zip" I need and how to install it to get the demo installation running?

Thanks in advance
Michael
