Hi Thorsten,

I will further elaborate my issue in a follow-up mail with some test setup and 
test data.

Keep you posted,
Robby

Hi guys,

I was just having a chat with my colleague about writing servlet services in 
one block and using them in another block.  And I told him apparently you can 
only return xml from a servlet service.  I found this out by writing a service 
(plain old XSLT) which takes as input XML and returns text or in my particular 
case JSON.

Whereas this XSLT gets the job done if I use it in a regular pipeline, I could 
not use it in a servlet service.  Is there a good reason the output from a 
servlet service can only be XML?  On the docs from C3 for instance 
http://cocoon.apache.org/3.0/reference/html-single/index.html I read following 
statement:

It is the responsibility of the Producer to decide whether a specific Consumer 
can be linked to it or not (that is, whether it can produce output in the 
desired format of the Consumer or not).

Does this mean C3 would not have this restriction?


I am not sure what you are referring to but it strikes me ought "a servlet 
service can only be XML". Need to find some time to setup a small test myself, 
but AFAIK the service can return whatever.
