XMLC & j2sdk1.4.1_01

Hello.

I have this problem when I try to compile this: (j2sdk1.4.1_01 )

E:\>xmlc Html.html

E:\>C:\j2sdk1.4.1_01\bin\java org.enhydra.xml.xmlc.commands.xmlc.XMLC
 -dom xerces -keep -urlregexpmapping ../../../../  ../ -delete-class
discardme Html.html
Html.java:15: Html should be declared abstract; it does not define
isSupported(java.la
ng.String,java.lang.String) in Html
public class Html extends org.enhydra.xml.xmlc.html.HTMLObjectImpl
implements org.enhydra.xml.xmlc.XMLO
bject, org.enhydra.xml.xmlc.html.HTMLObject {
       ^
1 error
Error: compile of generated java code failed


In this mail list I throw some solutions, but I don't know what is the best.
Thanks.
