I asked this question a while ago, visual support for Java DSL will be awesome. Think too much emphasis on Spring by the FuseSource team was a bit overloaded!
However, now that RedHat (JBoss) took over FuseSource, we'll see a more "standard' focus with Camel, this is great news!
Check out JBoss' SwitchYard project, it has some visual (outline) support for Camel. The JBoss project looks really good, compliments Camel with other useful technologies, BPMN, Rules Engines, CDI, etc.
Its not Spring only, its the XML DSL which is supported by
- OSGi Blueprint
And Fuse IDE supports all 3 of them.
At runtime Fuse IDE can view any number of Camel routes running in JVMs. It does not matter what kind of DSL you use to design the routes.
Runtime view = all of them
Design time view/editor = XML DSL only (currently).
