I changed the '' to {} like u said, not needed because when I dont use
the thread it works. Same with the pipelines, they work when I don't use
the thread (use_background_thread=false). I think I just need to be able
to set the environment (context?) inside the thread, check the
exceptions I get in the first message:
"org.apache.avalon.framework.context.ContextException: Unable to locate
object-model (No environment available)"
Relevant sitemap sections (which work when not using the thread):
<map:match pattern="pdf2_pipe/**">
<map:generate src="cocoon:/xsl-fo/{1}"/>
<map:serialize type="fo2pdf"/>
</map:match>
<map:match pattern="*.pdf2">
<map:call function="create_pdf">
<map:parameter name="report" value="{1}"/>
<map:parameter name="format" value="pdf2"/>
</map:call>
</map:match>
<map:match pattern="pdf2_display/**">
<map:read src="module:flow-attribute:file_name"
mime-type="application/pdf" />
</map:match>

The api says is should be an object...
So maybe try
cocoon.processPipelineTo(fmt+"_pipe/"+url, {} ,output_stream); //using object
literal
Thats not it, because when I set use_background_thread to false to do it
directly without a thread (the else) it works.
I don't know if you need a context but you sure aren't setting any...
I'm not setting a context in the thread, I guess I need to use the
context from the create_pdf function. How would I do that? Is there some
documentation for that somewhere?
Cheers,
Robby
