Camel Dynamic Routes

Student: Xueqiang Mi <alloyer AT gmail DOT com>
Mentor: Jonathan Anstey <janstey AT apache DOT org>

Project Description

We can already modify XML at runtime; we could do with visualizations using Scala, Ruby, Groovy, Python so that folks can view & edit the routes in whatever language they want and hack them. For more see the Web Console which supports updating the routes at runtime using the XML structure.

To do this we'll need to be able to turn a RouteDefinition back into the DSLs - such as Groovy/Ruby/Scala/Python

Week of June 15 - June 21, 2009

Week of June 22 - June 27, 2009

  • I want to solve it through digging into the ExpressionNode and ExpressionDefinition level, but after a lot of work and test, I found it so difficult because in ExpressionDefinnition, some Groovy closures are embedded in and hard to restore to the original states. I will post some of my experiments on mailing list for discusses.
