  Actually, you don't need to override setup().
  The base class of the XSP generated class already does that and provides
"protected Parameters parameters;"

  You can use directly in <xsp:logic>

  String entityType = this.parameters.getParameter("entityType");

  including the other nice features of Parameters such as defaulting and
converting to int, boolean, and so on.

    Wow. I did not know you could use the XSP to override the setup method.
That is VERY helpful. Thanks!!

      hi collin,

      with XSPs an easier alternative would be to pass your 'parameter' as a
request parameter.

      then you would:

      <map:match pattern="edit.xml">
          <map:generate type="serverpages" src="/docs/edit/item.xsp"/>
          <map:serialize type="xml"/>

      <map:match pattern="edit/*">
          <map:generate src="cocoon:/edit.xml?entityType={1}"/>

      then you can get the request parameter from within your XSP via the
request logicsheet (<xsp-request:get-parameter>) or via embedded logic
(request.getParameter ()).

      the other alternative; passing the parameter as a sitemap parameter:

      <map:match pattern="edit/*">
          <map:generate type="serverpages" src="/docs/edit/item.xsp">
              <map:parameter name="entityType" value="{1}"/>

      for this to work you have to embed the appropriate logic into your XSP
for retrieving that parameter; as your compiled XSP is a generator in the
end you accomplish this by overriding its setup() method and process the
parameter(s) there.

      just as a hint (take a look at the respective sources/docs):

      <xsp:page language="java" ...>
      <xsp:logic>    <!-- must occur before content so that it doesn't
become part of content/generate() method -->
          public void setup (SourceResolver resolver, Map objectModel,
String src, Parameters params) throws ...
              // process parameter(s) here

              super.setup (resolver, objectModel, src, params);

      <!-- content here -->

        Betreff: Pass custom parameters into an XSP


        I am trying to figure out how I can pass in custom parameters into
an already existing generator such as the XSP/serverpages generator.  Here's
my scenario:

        I receive a request for /edit/page

        Which matches /edit/*

        So from this matcher, I have {1} == "page".. I want to pass this off
to let's say

        /docs/xsp/edit/item.xsp  as a parameter named "entityType"

        So that in the XSP I can access the "entityType" variable.

        I think I'm missing something obvious. If someone could point me
into the right direction, I'd really appreciate it.
