Re: [trinidad] configuration: web.xml ordering

Matthias, your web.xml is quite similar to mine (actual working case).
What I did first - was simply to cut & paste from the wiki page all Trinidad stuff, appending it to the end of web.xml.
This appeared to be a logical choice. It didn't work.
Then from an old post I discovered that I had to comment out the <view-handler> line from faces-config.xml (it was there from Facelets installation). I didn't work either.
Then by accident I moved pasted stuff at the beginning of web.xml. It worked (well, it started, there are a number of pending failures to be discovered yet).
Just to avoid someone else to waste time through the same sequence, although I did not understand why.

Thanks -- Renzo

Hi, for the purpose of softly switching to Trinidad, I just reconfigured an
existing application - Tomahawk & Facelets based - to be Trinidad-ready. I
did this by adding proper entries to web.xml and faces-config.xml, then
adding the latest jar pairs for Trinidad. No source modifications.
I was fairly surprised to notice that result depends on element ordering
within web.xml.
Specifically, if appending all new Trinidad stuff at the end, then I get an
error at application startup: no Trinidad filter was found, and no rendering
context as well.

I am not really sure, but I think there is something in the servlet spec
whichs says that some elements have to be in a proper order...
(at least I saw a "warning" in eclipse's wtp web.xml editor)

After moving all to the beginning, application starts, although several
things do not work as before: I still have to investigate further, but first
I'd like to collect a few comments about the ordering topic, since I neve
saw it on any document - either Trinidad or Facelets based.
