Another possibility would be to create a java pipe. See e.g. for an
usage see
cocoon-rest-optional/src/main/java/org/apache/cocoon/rest/optional/sample/SendMailPipeService.java
and
cocoon-rest-optional/src/main/java/org/apache/cocoon/rest/optional/mail/pipelines/pipes/EmailPlainPipe.java

This gives you a broader possibility. For example in one project I
extended the pipeline interface to work with a hashmap and I injected
the values via the pipe. This way I did not need to bother with the
stream but directly could access the values I needed in the pipeline.
