Re: Lookup of generator failed

[Ivo Limmen]

I just found of that I casted the ServiceSelector wrong and that it 
resulted in a ClassCastException that is only logged in debug mode 
because it is wrapped into something else.

I just saw that the constructor is called with each request I make, I

I use Cocoon 2.1.2 on Tomcat 4.1.24. I had build an generator in 
Cocoon 2.0.3 and wanted to update the code to use the 
ServiceableGenerator class.
I added logging to each method of my generator but I see nothing. I 
added System.err outputs and only say that the constructor is called. 
So I at least know that the classes are found and that Cocoon 
instantiated my generator.
But setup() service() and dispose() are not called at all...


Is there no error in the error logs?  Where do you have your System.err 
outputs within the methods?  I'd guess that an exception is thrown in 
constructor or early in setup.  Also the default log levels have changed 
 in 2.1 - if you are logging at getLogger().debug() level you are 
probably not configured in logkit.xconf to output that level.
