I'm still quite a bit hazy on how to properly construct pipelines in C2a7. The docs and examples don't seem to be clearing it up too much for me. For instance, I'm trying to create a classic "Hello World" that uses XInclude to pull a message in from another XML file. I've added: <map:transformer name="xinclude" src="org.apache.cocoon.transformation.XIncludeTransformer"/> to the sitemap.xmap, and the pipeline for my webapp looks like this: <map:match pattern="helloworld.html"> <map:generate src="helloworld.xml"/> <map:transform type="xinclude"/> <map:transform src="helloworld.xsl"/> <map:serialize type="html"/> </map:match> helloworld.xml: <?xml version="1.0" ?> <page> <title>The Message</title> <xinclude:include href="message.xml" parse="xml"/> </page> message.xml: <?xml version="1.0" ?> <message>Hello World!</message> helloworld.xsl: <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:template match="page"> <HTML> <BODY> <H1><xsl:value-of select="title"/></H1> <BR/> <H1><xsl:value-of select="message"/></H1> </BODY> </HTML> </xsl:template> </xsl:stylesheet> I'm just getting: org.apache.cocoon.ProcessingException: Failed to execute pipeline.:java.lang.NullPointerException at org.apache.cocoon.components.pipeline.CachingEventPipeline.process(CachingEv entPipeline.java:228) at org.apache.cocoon.components.pipeline.CachingStreamPipeline.process(CachingS treamPipeline.java:344) at org.apache.cocoon.www.sitemap_xmap.process(sitemap_xmap.java:992) at org.apache.cocoon.www.sitemap_xmap.process(sitemap_xmap.java:886) at org.apache.cocoon.sitemap.Handler.process(Handler.java:175) at org.apache.cocoon.sitemap.Manager.invoke(Manager.java:97) at org.apache.cocoon.Cocoon.process(Cocoon.java:287) at org.apache.cocoon.servlet.CocoonServlet.service(CocoonServlet.java:463) Any help would be appriciated.
