Subject: Cocoon 2 generated SAX Exception
All,
I'm running into a reoccurring problem in pipeline processing where I get a
SAX Exception. It seems to happen when I place a DOM based transformer in
the pipeline after a series of SAX Transformations. However, if a manually
serialize the file and create a test pipeline that reads the file in as a
generator, the test pipeline works.
>From the sitemap:
<map:match pattern="showTree">
<map:generate type="file" src="sql/getMatrix.xml"/>
<map:act type="request">
<map:parameter name="parameters"
value="true"/>
<map:transform type="sql">
<map:parameter
name="use-connection" value="fp"/>
<map:parameter
name="show-nr-of-rows" value="false"/>
<map:parameter name="crop"
value="{cropCode}"/>
<map:parameter
name="username" value="{../../username}"/>
</map:transform>
<map:transform type="xslt"
src="stylesheets/matrixSQLToXML.xsl"/>
<map:transform type="xslt"
src="stylesheets/matrixAddSelf.xsl"/>
<map:transform
type="matrixTransformer"/><!--This is where SAX Exception occurs-->
<map:select type="parameter">
<map:parameter
name="parameter-selector-test" value="{exportType}"/>
<map:when
test="xml">
<map:serialize type="xml"/>
</map:when>
<map:otherwise>
<map:serialize type="svg2jpeg"/>
</map:otherwise>
</map:select>
<map:serialize type="xml"/>
</map:act>
</map:match>
Here is the stub for the matrixTransformer. TreeAnalysis returns an SVG-XML
Document. The entire document must be available for the runAnalysis method
to work properly:
import org.apache.cocoon.transformation.AbstractDOMTransformer;
import org.w3c.dom.Document;
import TreeAnalysis;
public class MatrixTransformer extends AbstractDOMTransformer {
TreeAnalysis treeAnalysis;
protected Document transform(Document doc) {
treeAnalysis = new TreeAnalysis();
log.debug("matrixTransformer START");
Document svgDocument = treeAnalysis.runAnalysis(doc);
log.debug("matrixTransformer END");
return svgDocument;
}
}
Here is the exception from the cocoon log. The debug logs from the
MatrixTransformer class are never written.

When I manually serialize the file as XML and read it as a generator in a
test pipeline, everything works.
<map:match pattern="testShowTree">
<map:generate type="file" src="sql/getMatrix.xml"/>
<map:act type="request">
<map:parameter name="parameters"
value="true"/>
<map:transform type="sql">
<map:parameter
name="use-connection" value="fp"/>
<map:parameter
name="show-nr-of-rows" value="false"/>
<map:parameter name="crop"
value="{cropCode}"/>
<map:parameter
name="username" value="{../../username}"/>
</map:transform>
<map:transform type="xslt"
src="stylesheets/matrixSQLToXML.xsl"/>
<map:transform type="xslt"
src="stylesheets/matrixAddSelf.xsl"/>
<map:serialize type="xml"/>
</map:act>
</map:match>
I manually save these results to a file (i.e. cache/testTree.xml) then use
this pipeline to read it.
<map:match pattern="testTree">
<map:act type="request">
<map:parameter name="parameters"
value="true"/>
<map:generate type="file"
src="cache/testTree.xml"/>
<map:transform type="matrixTransformer"/>
<map:serialize type="svg2jpeg"/>
</map:act>
</map:match>
So the above works, however when I aggregate these two steps, I get the
aforementioned exception.
Any help or guidance will be greatly appreciated.
Thanks,
-Aaron

This class was refactored in Cocoon 2.0.1. Can you upgrade to 2.0.1? It
might not have the issue you are describing.
