RIFE-Jumpstart

RIFE is such a terrific example of using continuations in a web application framework that it is too bad if giving it a try has glitches from the get-go.
The RIFE-Jumpstart will use Jetty so you will want to go into the Jetty subfolder and edit the jetty.xml such that the port value is something other than 8080. After that you will reach RIFE as something like

http://localhost:28282

You simply must confirm that your OS has the JAVA_HOME env variable set to a JDK. I am using RIFE for Java5 so mine set to

i:\java5\jdk

I tried using my own ClassPath tool from LogiqueWerks to get around this by being sure to hit the right tools.jar and javac.exe but I could not escape

class file has wrong version 49.0, should be 48.0

when launching from the RIFE-JUMPSTART directory with

ant run

This also means that you must have ant in your path.
It is annoying that most HTTP frameworks install without politely asking for an alternative to port 8080. OracleXE and SUN Application Server are the latest to do this to me.
There are some good video podcasts on RIFE - one at Google is about an hour long.
If I add some RIFE pages they will be over at eclectic-pencil.com Useful links include rifers.org and a Confluence link on DWR.
