[Paraview] ParaViewWeb installation - partial success, no mouse interaction

[Mario Rossi]

Dear Paraview(Web) Users and Developers,
I have installed ParaViewWeb as closely as possible after 
http://www.paraview.org/Wiki/ParaViewWeb_Building.

It seems to work partially, but not ready for "production" use.
These things are ok:
* http://localhost:8080/PWService lists the active processes
* http://localhost:8080/PWSimple shows the six spheres
* http://localhost:8080/PWConsole executes the example code when copy&pasted.

This does not work:
* http://localhost:8080/PWSimple does not rotate the spheres when dragging the 
mouse. There is no reaction at all. Only the flex renderer makes the status bar 
flicker between "Transferring data from localhost" and "Waiting for 
localhost..." when I drag the mouse inside. *Some* messages seem to be sent.
* http://localhost:8080/PWShuttle only shows the slider and the "Flash..." 
combobox and a blue area. I cannot interact with the slider or the combox box.

I am not sure if I followed the Wiki correctly.
The Wiki says: "The automatic launch of this executable[PWServer] is done by the 
WebServer/CoreService application."
And the Wiki mentions: "For the runtime ... ActiveMQ 3.x, the JMS brocker" (but 
no details for activemq installation are given)
I don't see where to set up the automatic launch of PWServer, and again the 
PWServer depends on a running ActiveMQ.
How I am starting things is the following:
1) $ activemq start
     The output is: ... INFO  BrokerService                  - ActiveMQ JMS 
Message Broker (localhost, ID:xyz:0) started
2) $ PWServer
     The output is: JMS Initialized in 0.138528 seconds
     sessionID : org.paraview.paraweb
     logLevel : ERROR
     Processing Engine Initialized in 0.590458 seconds
     Processing engine is started !
3) $ apache-tomcat-6.0.29/bin/startup.sh
     The output is: Using CATALINA_BASE:   /opt/tomcat/apache-tomcat-6.0.29
     Using CATALINA_HOME:   /opt/tomcat/apache-tomcat-6.0.29
     Using CATALINA_TMPDIR: /opt/tomcat/apache-tomcat-6.0.29/temp
     Using JRE_HOME:        /usr/lib/jvm/java-6-sun-1.6.0.22
     Using CLASSPATH:       /opt/tomcat/apache-tomcat-6.0.29/bin/bootstrap.jar

I don't see any problems in the output of these commands, but is it ok to start 
them manually in this order?

I am testing on a 2.8 GHz dual core Xeon with 2 GB of RAM. My first impression 
was that my setup is just extremely slow, but I doubt that this is the 
explanation. Firstly, the hardware should suffice, secondly there is absolutely 
NO interactivity.

Can somebody help and suggest how to debug problems, or what I could check?

Thanks for reading
Mario
