Creating An eXist Generator for Cocoon

[Christofer Dutz]

Hi,   I am quite new to this side of the Cocoon project ( usually I was just using Cocoon ), so please be patient.   A few weeks ago I joined the group developing the eXist Xml-Database and because of my experience with Cocoon I was assigned the task of integrating eXist into Cocoon. After finishing all work for being able to start/stop/access eXist locally ( not over HTTP or RPC ), I have started creating a new Generator called “org.apache.cocoon.generation.ExistGenerator” ( If I am not allowed to place the class there … please tell me. I just thought that it belonged there ). After finishing a first prototype of the generator, I wanted to test it. So I added following part to the Sitemap where the generators are defined : <map:generator name="exist" src="org.apache.cocoon.generation.ExistGenerator"/> This didn’t seem to cause any problems … so I added a simple match in the standard sample pipeline ( I am using a totally fresh installation of Tomcat and Cocoon 2 ) “ <map:match pattern="exist">        <map:generate type="exist" src="xPathExpression"/>        <map:serialize/> </map:match> When accessing this page I get a : UnnamedSelector: ComponentSelector could not find the component for hint: exist From Cocoon. Does this mean that the class couldn’t be found, or could there be a problem with the class itself ? My Generator extends the AbstractGenerator class. I hope this is the right way. If not, could someone please send me a small tutorial with the steps needed to create a new Generator ?   Thanx in advance,   Christofer Dutz C-Ware IT-Service Inh.
