RE: Problem with current build

Hi Jake,

I just don't think we should make a change like this that will so blatantly
break existing code. It was very non-obvious to me from the stack trace what
the error was, and I'm active on the list, familiar with the code, etc.
That's setting ourselves up for ticked off developers when they upgrade from
cvs (or to the newest build) and all of a sudden things don't work.

I think we CAN assume its XMLC for now, because a) that's all there is at
this point and b) when we get to the point of using other DOMLoaders we can
then add the tags to the assembler files.

The bottom line is we need to try and keep existing code from breaking
whenever possible, and this change (as it stands now) will break every ounce
of existing code with a very difficult-to-diagnose error unless manually
updates all their assembler files.

  Well, we can't really assume a default because, theoretically, we don't
know what someone is using to do their dom loading.  We can't just assume it
is XMLC.  If one does not want to provide the default in the assembler file,
then one needs to provide the default programmatically at the startup of
their application.  For instance...

  DefaultDOMLoader.getGlobalInstance().setDefaultDOMFactory(new
XMLCDeferredParsingDOMFactory());

  That is what I added to the component test cases.

  This is just a requirement that we have to live with if we want to claim
to have no particular dependency on XMLC or any other specific DOM
implementation in Barracuda which is what the whole DOMFactory, DOMLoader,
DOMWriter setup is all about is trying to archive; implementation
independence.

  Thoughts?

    Hi Jake,

    Ok, so in answer to my own question, I see that application-gateway.xml
now has a reference to <dom-loader> tags...and I remember seeing this in
emails over the past week, but I don't recall the specific details.

    I'm guessing the reason why things are blowing chunks are because I'm
not explicitly specifying this in my current application-gateway.xml. Is
this the case?

    If it is, we need to rethink this, because it will cause all existing
installations to fail until the dom-loader is specified. I think there MUST
be a default (ie. if not dom-loader tags are specified, use XXX, where XXX
is probably the new and improved XMLCDeferredParsingDOMFactory).

    Thoughts? Comments? Am I missing something here?

    Christian

      Ok, superclean seems to have fixed it. Which means something in the
sample.* fioles changed, right? Can you tell me exactly what...



      tia,

      Did you try doing a clean build?


      Try checking out the Barracuda CVS to a completely separate directory
than your current tree.  Then do "ant superclean".  Then do "ant
catalina-install".


      I just did exactly what I described above and everything works fine
under j2sdk1.4.1_02, Ant-1.5.3, and Tomcat-4.1.24.
