Generating plain text on Cocoon 2.1.6

I'm having problems generating plain text output (utf-8) on Cocoon 
2.1.6. I get a NullPointerException. The scenario is:

       <map:match pattern="proof/*.txt">
         <map:generate src="abstracts_for_proofing/{1}.xml"/>
         <map:transform type="xinclude"/>
         <map:transform type="xslt" src="xsl/text_out.xsl"/>
         <map:serialize type="text" />
       </map:match>

The XML files are UTF-8 and the XSL file starts out like this:


<xsl:output method="text" encoding="utf-8" media-type="text/plain"/>

<xsl:template match="/">
  	<xsl:processing-instruction
name="cocoon-format">type="text/plain"</xsl:processing-instruction>
  	<plain-text>
		<xsl:apply-templates />
	</plain-text>
</xsl:template>

The XSL works fine running locally in oXygen with Saxon 6.5.3. I've 
tried removing the processing instruction, but it makes no difference. 
I've also tried adding a UTF-8 text serializer to the sitemap like this:

<map:serializer logger="sitemap.serializer.text" mime-type="text/plain"
         name="text" src="org.apache.cocoon.serialization.TextSerializer">
         <encoding>UTF-8</encoding>
       </map:serializer>

but no joy.

I've included the top few lines of the stack trace below. Can anyone 
suggest what the problem might be?

Re: Generating plain text on Cocoon 2.1.6

Posted by Upayavira <uv...@upaya.co.uk>.
you need to show more of the exception stack trace. the bit you showed 
wasn't the bit that actually held the error.

regards, upayavira - who's shift key has stopped working ;-0

Re: Generating plain text on Cocoon 2.1.6

Posted by Martin Holmes <mh...@uvic.ca>.
Nailed it!

I had this in my stylesheet:

<xsl:output method="text" encoding="utf-8" media-type="text/plain"/>

Changing it to

<xsl:output type="text" encoding="utf-8" media-type="text/plain"/>

("type" instead of "method") solves the problem!

But that shouldn't be, should it? According to XSLT 1.0 and 2.0, the 
attribute should be "method". Am I missing something here?

Cheers,
Martin

Re: Generating plain text on Cocoon 2.1.6

Posted by Martin Holmes <mh...@uvic.ca>.
I now have a working system, and in case anyone else has the same 
problem, this is what I had to do:

1. Use an absolutely minimal xsl:output element in the stylesheet:

	<xsl:output encoding="UTF-8" />

2. Create my own serializer based on the standard text serializer, but 
with a new name and an explicit encoding parameter:

	<map:serializer logger="sitemap.serializer.text" 				 
mime-type="text/plain"
         	name="utf8text" 					
		src="org.apache.cocoon.serialization.TextSerializer">

		<encoding>UTF-8</encoding>

       	</map:serializer>

3. Use that serializer in my map:match:

	 <map:serialize type="utf8text"/>

No other combination (and I tried virtually everything!) would work 
properly; some caused the null pointer exception in Xalan, some resulted 
in empty XML documents, and some tripped up when encountering a 
character with a codepoint above 255.

This was Cocoon 2.1.6 running on Tomcat 5.5, with Java 1.5.

Hope this helps someone!

Re: Generating plain text on Cocoon 2.1.6

Posted by Martin Holmes <mh...@uvic.ca>.
Hi there,

When I switch to the XML serializer, I get an empty XML document:

<?xml version="1.0" encoding="ISO-8859-1"?>

with no root element, and the wrong encoding.

This is strange; something must be throwing the Xalan parser for a loop, 
but there's nothing weird at all in the XSL as far as I can see; it's 
adapted from another file which works fine on a different installation 
of Cocoon (2.1.5). I've copied the XSLT below -- can anyone see anything 
wrong here?

Thanks for the other stack trace. Unfortunately, those ones are usually 
very difficult to debug, as the error shows up in Xalan as a null 
pointer exception, which was actually triggered by something much 
further back in the pipeline.

Now, have you tried replacing <map:serialize type="text"/> with 
<map:serialize type="xml"/>

What do you see? Does it produce your text content, but wrapped in XML?

Also, the processing instruction, to my knowledge, won't make any 
difference. It looks like a Cocoon 1.x instruction, that Cocoon 2 
doesn't know about. Configuration like that happens in the sitemap, not 
in processing instructions.
