Subject RE: Runnable in flowscript?
Date Fri, 19 Mar 2010 18:53:52 GMT
You're in fact using a closure here so I'm not sure if that's causing issues. Can you add following
debug statements?

var r = new java.lang.Runnable() {
    run: function() {
        //add following print statements
        print("fmt= " + fmt);
        print("output_stream = " + ouput_stream);
        // gives an exception here on the console
        cocoon.processPipelineTo(fmt+"_pipe/"+url,{}, output_stream); 
        output_stream.close();
    }
};

Subject: Re: Runnable in flowscript?

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>

CAN I SEE relevant sitemap snippets and corresponding generator for this pipeline?? And still
replace the '' by {} just to be sure
