Debugging Camel Routes in Eclipse

[jkrozak]

Folks,

i am a Camel newbie and I am having trouble setting breakpoints and debugging camel routes in Eclipse.  i have a simple route that pulls an XML file from a directory, passes it to a class that implements Processor, and then sends that output to another directory.  i simply want to debug the Processor step in Eclipse, but i never seem to hit the breakpoint.  Any hints?

Its just java code, so if you do set a breakpoint inside your java code in a custom Processor then it should hit it.

Can you do a system out println in the processor and make sure it prints that. Then set a breakpoint on it, and run it in debug mode.

Yes, i did just that - did a System.out.println from within the Process, which works fine.  Then I set a breakpoint on that same println and never hit it.  Is this a case of the route being multithreaded and I need to do something to jump over to it somehow?

No it must be eclipse not being able to align source code when debugging.

So when you set a break point on line XXX in src file, it cannot align that. How do you start the Camel from Eclipse?

[jkrozak]

I start the route from a regular Java console application as follows.  Each Processor has code that i want to step through in the debugger.  When i set a breakpoint in Processor1, i never reach it and when i continue the run within the debugger, the route never seems to complete:

public static void main(String[] args)

{

     try

     {

          CamelContext context = new DefaultCamelContext();

          context.setTracing(true);

          context.addRoutes(

          new RouteBuilder()

          {

               public void configure()

               {

from ("file:src/main/resources/messages/src?noop=true").

process(new Processor1()).

process(new Processor2()).

process(new Processor3()).

to ("file:src/main/resources/messages/dest");

               }

          }

     );

     // Start the route...

     context.start();

     Thread.sleep(60000);

     // Stop the CamelContext

     context.stop();

...

Well that is odd. Try setting a break point in the main method to see if it can debug there.

And make sure you compile with debug info turned on.
