Novel HTTP methods and the standard Sun Java SDK (was RE: Revised draft of CBD)

I was not referring to the creation of a servlet responding
to URIQA requests, but for using the Java API to *make*
requests to other URIQA-englightened servers.

If you try to set the request method to anything other than
one of the "standard" methods, an exception is thrown, but
*without* the side effect, so you can't just catch and 
disregard the exception (meaing "I know what I'm doing")
and proceed.

I tried to get a simple change made to the SDK where a
single line of code was moved (not changed) such that the
method was set prior to the test and thrown exception, so
that careless or naiive users would still have the "protection"
of the exception being thrown but savvy (or careless ;-)
users could disregard the exception and proceed with the
request, using the specified "non-standard" method.

The change wouldn't even impact any existing applications,
which would presume the exception in any case.

See the attached slides. It's trivially simple.

At present, you can't use the standard Java SDK for URIQA,
WebDAV, or any other solution employing "non-standard"
methods, which is a great pity.

Cheers,

Patrick
