I was trying to integrate the SAXON processor into Cocoon because my webapp needs it to carry out some transformations.
(I use Cocoon 2.1.3 under Tomcat 4.1.29 . I want to install Saxon 7.8)
My cocoon webapp runs directly under the Tomcat webapps directory.
I read some documentation and I did the following:
1) copy saxon jars into WEB-INF/lib directory;
2) I've added this code to cocoon.xconf:
<component role="org.apache.cocoon.components.xslt.XSLTProcessor/Saxon" class="org.apache.cocoon.components.xslt.XSLTProcessorImpl" logger="core.xslt-processor">
<parameter name="use-store" value="true"/>
<parameter name="incremental-processing" value="false"/>
<!-- the path to the transformer-factory has changed ... -->
<parameter name="transformer-factory" value="net.sf.saxon.TransformerFactoryImpl"/>
</component>
3) in my sitemap.xmap I added this under the transformers section:
<map:transformer name="xslt-saxon" pool-grow="2" pool-max="32" pool-min="8" src="org.apache.cocoon.transformation.TraxTransformer">
<use-request-parameters>false</use-request-parameters>
<use-browser-capabilities-db>false</use-browser-capabilities-db>
<xslt-processor-role>org.apache.cocoon.components.xslt.XSLTProcessor/Saxon</xslt-processor-role>
</map:transformer>
4) when I want to use saxon (normally I use the default transformer) I write:
<map:transform type="xslt-saxon" src="transforms/X3dToVrml97.xsl"/>
(with the default xslt processor the vrml stylesheet does not transforms correctly)
But the problem is not in such pipeline (where the saxon processos is called): I get one error even in the first page of my webapp (where the default cocoon processor is used). Is seems like there's a conflict, but I have no idea on where and why.
Please give me some hint to solve this problem. Thanks in advance! Best regards, Nesto
