ZipArchiveSerializer question
Hello,
Is it possible to use the ZipArchiveSerializer and process the generator
output straight off without sending it to a disk file first?
I think this stream compression is possible but gives a less compressed
result.
Thanks

Currently Cocoon 2.1.11, I should upgrade to 2.2 though.

Which version Cocoon are you using? This sounds like you an old problem
which was fixed in 2.1.7.

Thanks Jasha,
Adding the attribute mime-type="application/zip" to the <map:serialize
type="zip"/> fixes the problem!
However, it is already in the in the main sitemap.xmap:
<map:serializer logger="sitemap.serializer.zip" mime-type="application/zip"
name="zip" src="org.apache.cocoon.serialization.ZipArchiveSerializer"/>
So why should this be necessary?

Have you defined a mime-type for the zip-serializer?
If not, try adding the attribute mime-type="application/zip" to either
<map:serialize type="zip"/> in your pipeline or to the <map:serializer
name="zip"/> in map:components.

Re: ZipArchiveSerializer question

Hello Alfred,
Say have a url 'http://mysite.com/cocoon/test.xml' and I want to add an
option to save the same test.xml file as a zip archive.
I see now that if I have the following sitemap:
<map:match pattern="*.zip">
<map:generate src="nothing.xml" type="file"/>
<map:transform src="zip.xsl">
<map:parameter name="source" value="{1}"/>
</map:transform>
<map:serialize type="zip"/>
</map:match>
<map:match pattern="*">
<map:generate src="{1}.xml"/>
<map:serialize type="xml"/>
</map:match
Where nothing.xml is effectively an empty xml file having only <xml></xml>
tags.
And the zip.xsl is as follows:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://mine">
<xsl:param name="source"/>
<xsl:template match="/">
<zip:archive xmlns:zip="http://apache.org/cocoon/zip-archive/1.0">
<zip:entry>
<xsl:attribute name="name"><xsl:value-of
select="$source"/></xsl:attribute>
<xsl:attribute name="src">cocoon:/<xsl:value-of
select="$source"/></xsl:attribute>
</zip:entry>
</zip:archive>
</xsl:template>
</xsl:stylesheet>
I am directing the output of the "*" pipeline into the "*.zip" pipeline.
This almost seems to work, but the browser does not seem to understand that
file is a zip, so maybe I'm still doing something incorrectly, thanks for
your help.

I don't quite understand what your question is.
The ZIPArchiveSerializer does not write any on-disk ZIP file. It
buffers in memory and streams it to the HTTP response.
If you on the client side don't want to store the ZIP file, you can
unpack it immediately:
curl http://... | jar xfv -
