No that exactly seems to be your problem. Fix that and you are good.

These are two different things. And RCL does work with class files -  
not source files. Still it does not depend on a particular IDE. It  
also works with IDEA, Netbeans or whatever. It's just that someone  
else is doing the compilation and the RCL will pick up the result.

As said before. JCI could also do the compilation. But this is added  
complexity that you usually don't need. I suggest you get the easy  
part working first ;)

You are not providing it the updated class files.

No you got it wrong. Again: it works with class files.

You change your source file. Now you hit on save in Eclipse. That will  
trigger the compilation of the class file. In other IDEs you might not  
have the incremental build and you have to press "build". Then your  
IDE will build the class file and write it (usually) to the target  
directory. The RCL notices something has been updated and reloads that  
part of your cocoon app.

My suggestion:

1. close eclipse
2. rm -R target
3. mkdir target
4. start eclipse
5. project -> clean
6. make sure project -> build automatically is checked
7. you should not see any errors
8. run find target -name "*.class"

You should then see all the class files in the target dir. If you have  
pointed the RCL to that target dir everything should work like charm.
If not check the project settings on the source tab for the output dir.
