Porting Paloose Sites to Cocoon

It is inevitable that some sites will grow so much in both traffic and functionality that moving the whole thing to Cocoon is sensible. It is obviously important that the minimal amount of work is done in doing this. The whole process is relatively simple with very little in Paloose that cannot be moved to Cocoon. The following is a summary of the important points to remember:

An example

The example below is a very simple private site that I run to serve my work at home. I have it both in Paloose and Cocoon forms as a test of porting.

Root sitemap

The sitemap component declaration is where the most change must occur. In the Paloose sitemap there is:

<map:components> <map:generators default="file"> <map:generator name="file" src="resource://lib/generation/FileGenerator"/> </map:generators> <map:transformers default="xslt"> <map:transformer name="xslt" src="resource://lib/transforming/TRAXTransformer"> <map:use-request-parameters>true</map:use-request-parameters> </map:transformer> <map:transformer name="i18n" src="resource://lib/transforming/I18nTransformer"> <map:catalogues default="index"> <map:catalogue id="index" name="index" location="context://content/translations"/> </map:catalogues> <map:untranslated-text>untranslated text</map:untranslated-text> </map:transformer> </map:transformers> <map:serializers default="html"> <map:serializer name="html" mime-type="text/html" src="resource://lib/serialization/HTMLSerializer"/> <map:serializer name="text" mime-type="text/plain" src="resource://lib/serialization/TextSerializer"/> <map:serializer name="xhtml" mime-type="text/html" src="resource://lib/serialization/XMLSerializer"> <map:doctype-public>-//W3C//DTD XHTML 1.0 Transitional//EN</map:doctype-public> <map:doctype-system>http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd</map:doctype-system> <map:omit-xml-declaration>yes</map:omit-xml-declaration> </map:serializer> </map:serializers> <map:matchers default="wildcard"> <map:matcher name="wildcard" src="resource://lib/matching/WildcardURIMatcher"/> <map:matcher name="regexp" src="resource://lib/matching/RegexpURIMatcher"/> </map:matchers> <map:readers default="resource"> <map:reader name="resource" src="resource://lib/reading/ResourceReader"/> </map:readers> <map:selectors default="browser"> <map:selector name="browser" src="resource://lib/selection/BrowserSelector"> <browser name="explorer" useragent="MSIE"/> <browser name="pocketexplorer" useragent="MSPIE"/> <browser name="handweb" useragent="HandHTTP"/> <browser name="avantgo" useragent="AvantGo"/> <browser name="imode" useragent="DoCoMo"/> <browser name="opera" useragent="Opera"/> <browser name="lynx" useragent="Lynx"/> <browser name="java" useragent="Java"/> <browser name="wap" useragent="Nokia"/> <browser name="wap" useragent="UP"/> <browser name="wap" useragent="Wapalizer"/> <browser name="mozilla5" useragent="Mozilla/5"/> <browser name="mozilla5" useragent="Netscape6/"/> <browser name="netscape" useragent="Mozilla"/> <browser name="safari" useragent="Safari"/> </map:selector> </map:selectors> </map:components>

The Cocoon version uses the same with the src attribute changes:

<map:components> <map:pipes default="noncaching"> <map:pipe name="caching" src="org.apache.cocoon.components.pipeline.impl.CachingProcessingPipeline"/> <map:pipe name="noncaching" src="org.apache.cocoon.components.pipeline.impl.NonCachingProcessingPipeline"/> </map:pipes> <map:generators default="file"> <map:generator name="file" src="org.apache.cocoon.generation.FileGenerator" /> </map:generators> <map:transformers default="xslt"> <map:transformer name="xslt" src="org.apache.cocoon.transformation.TraxTransformer"/> <map:transformer name="i18n" src="org.apache.cocoon.transformation.I18nTransformer"> <catalogues default="index"> <catalogue id="index" name="index" location="context://content/translations"/> </catalogues> <map:untranslated-text>untranslated text</map:untranslated-text> </map:transformer> </map:transformers> <map:serializers default="xhtml"> <map:serializer name="html" mime-type="text/html" src="org.apache.cocoon.serialization.HTMLSerializer"/> <map:serializer name="text" src="org.apache.cocoon.serialization.TextSerializer" mime-type="text/plain"/> <map:serializer name="xhtml" mime-type="text/html" src="org.apache.cocoon.serialization.XMLSerializer"> <map:doctype-public>-//W3C//DTD XHTML 1.0 Transitional//EN</map:doctype-public> <map:doctype-system>http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd</map:doctype-system> <map:omit-xml-declaration>yes</map:omit-xml-declaration> </map:serializer> </map:serializers> <map:matchers default="wildcard"> <map:matcher name="wildcard" src="org.apache.cocoon.matching.WildcardURIMatcher"/> <map:matcher name="regexp" src="org.apache.cocoon.matching.RegexpURIMatcher"/> </map:matchers> <map:readers default="resource"> <map:reader name="resource" src="org.apache.cocoon.reading.ResourceReader"/> </map:readers> <map:selectors default="browser"> <map:selector name="browser" src="org.apache.cocoon.selection.BrowserSelector"> <browser name="explorer" useragent="MSIE"/> <browser name="pocketexplorer" useragent="MSPIE"/> <browser name="handweb" useragent="HandHTTP"/> <browser name="avantgo" useragent="AvantGo"/> <browser name="imode" useragent="DoCoMo"/> <browser name="opera" useragent="Opera"/> <browser name="lynx" useragent="Lynx"/> <browser name="java" useragent="Java"/> <browser name="wap" useragent="Nokia"/> <browser name="wap" useragent="UP"/> <browser name="wap" useragent="Wapalizer"/> <browser name="mozilla5" useragent="Mozilla/5"/> <browser name="mozilla5" useragent="Netscape6/"/> <browser name="netscape" useragent="Mozilla"/> <browser name="safari" useragent="Safari"/> </map:selector> </map:selectors> </map:components>

Obviously in the Cocoon sitemap it is possible to manage the cache, logging and component pools which are not present in Paloose.

What about the Subsitemaps, XML Content and XSL Transforms?

Absolutely nothing to do here at all. Good isn't it?

Ok, that is not strictly true, on my home web site and this site I had to change the subsitemap "src" attributes. But other than that nothing. However in future the authorisation and continuations that I am currently adding will require a slightly different use of session variables in the XML. When this is added I will detail the differences then. The authorisation (login etc.) is working on the next version and I am finalising the form continuations. Watch this space.
