WG: [FLOW] cocoon.processPipelineTo, NullPointerException

[Markus Heussen]

FLOW:

cocoon.processPipelineTo("test",{ test : doc },os); // doc = w3c.doc


SITEMAP:

<map:match pattern="test">
        <map:generate type="jx" src="jx.xml"/>
        <map:transform type="xsltc" src="test.xsl"/>
        <map:serialize type="xml"/>
</map:match>


jx.xml:

<jx:template xmlns:jx="http://apache.org/cocoon/templates/jx/1.0";>
${test}
</jx:template>


After the pipeline processing in my logs I can see the results of the doc
transformed with test.xsl. Everything seems to work as expected but in my
output stream I also have the following exeption:

<test xmlns:v="http://schema.rheinland.net/Versicherung.htm";
xmlns:kfz="http://schema.rheinland.net/Kfz.htm";
xmlns:rhld="http://schema.rheinland.net/soap/header/rhld.htm";>
                        test
                </test><?xml version="1.0" encoding="ISO-8859-1"?>

Can anybody tell me what I'm doing wrong? Or is there anybody who can help
me finding a better way? I don't want to use flowscript or java within my
flowscript to do things that are usally done within the sitemap like
transformations.

By the way: If I don't do the transformation everything works fine.

Thanks, Markus

Betreff: [FLOW] cocoon.processPipelineTo


Hi,

can someone tell me how I can use the cocoon.processPipelineTo method with a
given w3c document as the initial input (generator) of a pipeline matcher.

For example:

cocoon.processPipelineTo("matcher",w3cDocumentObject,ouputStream);

The w3cDocumentObject is the content normally produced by using a generator,
but in this case I do not need to produce the xml content using a generator.
But it is required to start a pipeline with it.

Any idea?

Thanks, Markus
