Cocoon 2.2 Web 2.0
A Web 2.0 application
• Use of other resources via REST
• Cocoon as a web service
• Rich client interface

Cocoon archetypes
archetype |ˈärk(i)ˌtīp| |ˌɑrk(ə)ˈtaɪp| |ˌɑːkɪtʌɪp|nouna very typical example of a certain person or thing : the book is a perfect archetype of the genre. See note at model .

REST
The REST example
• Use Flickr API to display content through Cocoon
• http://www.flickr.com/services/api/request.rest.html
• http://www.flickr.com/services/rest/?method=flickr.method.name&name=value
<map:match pattern="flickr"> <map:generate src="......"/><map:serialize type="xml"/>
</map:match>
<map:match pattern="flickr"> <map:generate src="......"/><map:serialize type="xml"/>
</map:match>
http://www.flickr.com/services/rest/?method=flickr.people.getPublicPhotos&api_key=1234&user_id=abcd
Taking it further ...
<map:match pattern="flickr"> <map:generate src="......"/> <map:transform src="flickr2html.xsl"/><map:serialize type="html"/>
</map:match>
<xsl:template match="/"> <html> <head> <link rel="stylesheet" href="styles/site.css" type="text/css" /> </head> <body> <xsl:apply-templates/> </body> </html> </xsl:template> <xsl:template match="rsp"><xsl:apply-templates/></xsl:template> <xsl:template match="photos"> <h1><xsl:value-of select="@total"/> photos</h1> <table> <xsl:apply-templates/> </table> </xsl:template>
<xsl:template match="photo"> <tr> <td><img src="http://farm{@farm}.static.flickr.com/{@server}/{@id}_{@secret}_s.jpg"/></td> <td><xsl:value-of select="@title"/></td> </tr> </xsl:template>
http://www.flickr.com/services/rest/?method=flickr.photos.geo.getLocation&api_key=1234&photo_id=5678
Adding location...
Pipelines...
Unix solution:grep index.html access.log | awk ‘{print $2 }’ | sort | uniq | wc -l
Pipelines: specialised components glued together
<xsl:template match="photo"> <xsl:copy><!--copy node being visited--> <xsl:copy-of select="@*"/><!--copy of all attributes--> <ci:include src="http://www.flickr.com/services/rest/?method=flickr.photos.geo.getLocation&api_key=1234&photo_id={@id}" select="rsp/photo/location" parse="xml"/> </xsl:copy> </xsl:template>
<map:match pattern="flickr"> <map:generate src="......"/> <map:transform src="getLocation.xsl"/> <map:transform type="cinclude"/> <map:transform src="flickr2html.xsl"/><map:serialize type="html"/>
</map:match>
And presenting it... <xsl:template match="photo"> <tr> <td><img src="http://farm{@farm}.static.flickr.com/{@server}/{@id}_{@secret}_s.jpg"/></td> <td><xsl:value-of select="@title"/></td> <xsl:if test="location"> <td> <xsl:apply-templates select="location"/> </td> </xsl:if> </tr> </xsl:template>
<xsl:template match="location"> <xsl:value-of select="locality"/><br/><xsl:value-of select="country"/> </xsl:template>
Building pipelines<map:match pattern="flickr"> <map:generate src="......"/> <map:transform src="getLocation.xsl"/> <map:transform type="cinclude"/> <map:transform src="yahoomaps.xsl"/> <map:transform type="cinclude"/> <map:transform src="flickr2html.xsl"/><map:serialize type="html"/>
</map:match>

Web Services
What flavour?
• SOAP, WS-*, ...
• http://cocoon.zones.apache.org/demos/release/samples/blocks/axis/status.xsp
• http://ws.apache.org/
The SOAP example
<map:match pattern="news"> <map:generate src="......"/><map:transform src="photosearch.xsl"/><map:transform type="cinclude"/><map:transform src="photoinsert.xsl"/><map:serialize type="xml"/>
</map:match>
RSS serving example
News/Flickr Mashup
The Rich GUI
Rich GUIs in Cocoon
• Power of CForms’ widget-based framework
• DOJO
The GUI example

<dependency> <groupId>org.apache.cocoon</groupId> <artifactId>cocoon-ajax-impl</artifactId> <version>1.0.0-RC1-SNAPSHOT</version></dependency>
But there’s more...
• Authentication
• Blogs
• Microformats
• Semantic
