Re: [Springframework-developer] XMLC Support

[Juergen H. <ju...@in...>]

Guys,

Do we really want to ship this out-of-the-box in Spring core? This is nearly
1.8 MB of additional third-party jars, half of it cause by the great XMLC
decision to depend on a repackaged Xerces version...

If I remember correctly, that was also the original rationale for *not*
including it in Spring in the first place. I think that reason is still
valid, in particular due to the fact that the AbstractXmlcView base class is
so extremely thin.

BTW, we don't need an XmlcLoaderServlet or XmlcLoaderListener.
XMLCContext.getContext(servletContext) creates a new XMLCContext on first
access but then returns the existing instance. No need to initialize this in
a separate servlet or listener!

Effectively, a custom View implementation that uses XMLC could look as
follows - without any XMLC-specific base class shipped in Spring:

public abstract class MyXmlcView extends AbstractView {

  protected void renderMergedOutputModel(
      Map model, HttpServletRequest request, HttpServletResponse response)
throws Exception {

    this.xmlcContext = XMLCContext.getContext(getServletContext());
    OutputOptions oo = new OutputOptions();

    XMLObject xo = // creating the XMLObject from the model

    response.setContentType(getContentType());
    this.xmlcContext.writeDOM(request, response, oo, xo);
  }
}

Given how concise this, it seems to me that we really don't need to ship an
AbstractXmlcView class for this. Showing that skeleton code in the reference
docs or on the Wiki should be enough...

All,

I just committed basic XMLC support to CVS. This is based heavily on the
work Rod did in his original book.

Let me have your thoughts.
