Subject Re: Sending a parameter to Xerces (allow java char encodings, eg MacRoman )
Date Sat, 17 Aug 2002 14:53:46 GMT
OK! I've finally gotten this thing working in Cocoon 2.0.3!!! Thanks 
for your assistance (and patience) Vadim.

So now I can have a document with XML Decln: <?xml version="1.0" 
encoding="MacRoman"?> and Cocoon will now read it, and interpret the 
characters properly.

I modified the Avalon Excalibur JaxpParser.java from April 2002 (v1.1 
in CVS) and it overrides the JaxpParser.class in 
avalon-excalibur-vm12-20020705.jar which ships with Cocoon 2.0.3.

Here is a diff... note there are some debug lines that need removing, 
and perhaps it should leave allow-java-encodings as "false" by 
default, not sure... anyway, here it is.

Perhaps this change could be incorporated into Excalibur for the 
benefit of anyone else who wants to parse "weird" character 
encodings???

Cheers

Jesse
