Pass the content of a pipeline to a flow

Is it possible to pass the contents of a pipeline to a flow?

I tried:

        <map:pipeline>
            <map:match pattern="myflowurl">
                <map:call function="myflow">
                    <map:parameter name="someval" 
value="{cocoon:/somepipeline/element/stuff}"/>
                </map:call>
            </map:match>
        </map:pipeline>


but got error :(

Hi ypomonh,

I guess you can use the NullOutputStream for that:

cocoon.processPipelineTo("factorial", {}, new 
org.apache.cocoon.util.NullOutputStream());

Kind regards,

You should use org.apache.cocoon.components.flow.util.PipelineUtil. It offers 3
methods processToStream(), processToSAX() and processToDOM(). There are for sure
samples in the Cocoon code base or in the list archives.

Hi Johannes!

As far as I understand since processPipelineTo() can only output to a 
java.io.OutputStream, I can only use it to serialize something on the disk.

Is it possible to handle this stream inside my flowscript? I am not 
fluent in java but I think that there is nothing I can really do with a 
java.io.OutputStream...

try cocoon.processPipelineTo()

as documented (http://cocoon.apache.org/2.1/userdocs/flow/api.html)
