Dear all,
I'm a bit confused what's the difference between servlet and cocoon
protocols in Cocoon 2.2.
I have a pipeline that takes a request - the first step in that pipeline is
an aggregated generator, where one of the map:part calls internal pipeline
(<map:part src="servlet:/get_ids_for_solr/{1}/{2}"/>)
>From that internal pipeline I call a function at the flow script where I
need to access certain url paramaters from the original request. With the
servlet protocol (of that map:part from the main pipeline) I don't seem to
be able to access url parameters from within flowscript - I have a parameter
called q & in flowscript if I do cocoon.request.q I get the value undefined.
Should I be able to access url parameters in flow using the servlet
protocol?
I also tried to implement the solution using cocoon: protocol - using this
approach I can access parameters in the flow, using cocoon.request.q.
When I extract the url parameter in flow, I then use sendPage to call
another entry in the sitemap (shown below).
<map:pipeline>
<map:match pattern="get_chapter_content_solr/*">
<map:generate type="request">
<map:parameter name="id" value="{1}"/>
</map:generate>
<!-- Constructs the <cinclude:include> element. -->
<map:transform src="xsl/solr-chapter-view.xsl">
<map:parameter name="host" value="${solr.baseurl}/select"/>
</map:transform>
<map:transform type="cinclude"/>
<map:transform type="saxon" src="xsl/solr-chapter-content.xsl"/>
<map:serialize type="xml"/>
</map:match>
</map:pipeline>
When calling this pipeline using the cocoon: protocol the
solr-chapter-view.xsl transformation step in the pipeline doesn't seem to
get run. But when I use the servlet protocol I get the output I expect (but
am unable to pick up the url parameter mentioned above in the flow).
So, essentially using the servlet protocol this pipeline works fine, but I
can't access the url param I need. Using the cocoon protocol the request
param can be extracted in flow, but the pipeline above doesn't seem to work.
Did anyone has the same problem of accessing url parameters in flow while
using servlet protocol? Does anyone have any suggestions?
I would be extremely grateful for any tip.
Many thanks,
Daria
