This seems to be a problem. I have placed my classes in a specific package (under the %TOMCAT_HOME%/webapps/cocoon/WEB-INF/classes directory), included the right import in my xsp page and it worked. So problem solved, but I still find it strange that the Action works without the custom classes being in a package and that the XSP doesn't work. > In my sitemap I have added this action > <map:action name="upload" src="Upload"/> > > The pipeline where I am using this action is defined as follows: > <map:match pattern="add-upload.xml"> > > <map:act type="upload"> > <map:generate type="serverpages" src="add/add-upload.xsp"> > <map:parameter name="use-request-parameters" value="true"/> > </map:generate> > </map:act> > <map:serialize type="xml"/> > </map:match> > > The pipeline works. > I can process this data in my class Upload. > > In this class Upload I generate a vector with instances of the class > 'Frequentie' which I want to pass in the following way to my xsp-page: > (found this method on > http://www.theserverside.com/tt/articles/article.tss?l=Cocoon ) > > (in the act method) > <code_snippet> > Vector frequenties = new Vector(); > Frequentie newF = extractData(datasheet); > frequenties.add(newF); > // there are in fact a series of 'Frequentie' instances that are added > request.setAttribute("frequenties", frequenties); > </code_snippet> > > In my XSP-page I try to access this in the following way: > > Vector frequenties = (Vector) <xsp-request:get-attribute > name="frequenties"/>; > Iterator it = frequenties.iterator(); > > // test > while (it.hasNext()) > { > Frequentie f = (Frequentie) it.next(); > <tr> > <td><xsp:expr>f.getNaam()</xsp:expr></td> > </tr> > } > > But the strange thing (in my eyes) is that the class Frequentie is not > known in the context of the XSP-page.
