             Summary: Mailet pipeline ui edition tool
                 Key: JAMES-1932
                 URL: https://issues.apache.org/jira/browse/JAMES-1932
             Project: James Server
          Issue Type: Task
            Reporter: Matthieu Baechler


James has to concept of mailet pipeline : for any incoming email, the email is 
passing through the pipeline the is made of matchers and mailets. These 
components allow to implement business rules based on some xml configuration 
and some java component.
That's a great strength of James and a lot of people use it for this capability.
Nevertheless, editing the pipeline and making tests is painful right now, you 
are left finding solutions like "edit xml, launch server, send an email, read 
logs".
To ease adoption, we would like to make that process easy and fun by :
* providing a web ui frontend to design the pipeline
* given a set of emails, make it possible to visualise each email flow into the 
mailet pipeline to test it
* define a way to express the expected results to make sure people can save 
their work into automated tests

To implement that, the student must know enough about web frontend dev to 
implement a pipeline designer and debugger.
She or he will need to know some java to implement server side logic for :
* make james accept to reconfigure its pipeline at runtime to take 
modifications into account
* design a protocol to stream debug data from a pipeline to the web ui and 
implement it server-side in java
* implement a junit runner to be able to run some special mailet tests based on 
the work done in the web designer.
