[Bodington-developers] Removal of System property (bodington.home)

[Matthew B. <mat...@co...>]

I have had a quick hack at removing the system property bodington.home 
that is used by Bodington. The problem with using a System property is 
that if you have two copies of Bodington running in the same Servlet 
container they will share the value (bad).

The bodington.home property was almost exclusively used to load the 
DTDs. So I have moved the DTDs into the classpath and hacked up a new 
EntityResolver that looks in the classpath by default. This means that 
things like template compilation don't need to have properties set to work.

The correct way to solve this would have been to use a CatalogResolver 
(http://xml.apache.org/commons/components/resolver/) which I might sort 
out at some point down the road. Attached is my current patch for 
WebLearn HEAD at fixing this. I'll push it across to Bodington HEAD 
unless anyone has any objections.

NB: As a side note it seems that Bodington doesn't use the DOCTYPE 
declaration correctly and confuses the PUBLIC and SYSTEM attributes 
(look at any of the templates). I'm guessing this was done because the 
XML parser doesn't assume the SYSTEM DTD relative and so passes it 
through untouched.

As always I forgot to attach the patch.

that will solve problems for use, running multiple bods.

as an aside - talk of DTDs frightens me at the moment as the <template> 
element has changed to cater for i18n - the resource-file attribute 
won't be in the dtd.

is it worth moving to a schema while we're/you're at it?

The only System property left is bodington.properties but that one is 
quite simple to remove (I think).

It should be quite easy to add in the additional attributes/elements. 
Validation isn't required on so you will just get lots more warnings I 
think.

:-) At the moment the DTDs are very similar to the orginal XHTML DTDs 
and so moving to a XSD would make them quite different (does an official 
XSD for XHTML exist?). I don't mind it changing but only saw this as a 
short term hack to allow multiple bodingtons to run in the same container.

I tried to use an XHTML schema with LUSID and it led to all sorts of
validation problems so I went back to the DTD. I cant remember the details
but my XHTML was pretty simple and was littered with warnings. Most XHTML
docs out there seem to reference the DTD and not the schema.

I think I got the XSD from http://schneegans.de/sv/

Should read:

XML parser doesn't assume the PUBLIC DTD relative and so passes it
through untouched.
