Re: AW: AW: [Digester] using Schema Validation
Eureka! I've finally found a solution,
First, I tryed your example with no complaints from Digester.
Then I enabled log from org.apache.commons which was disabled before
(ugly thing when debugging :( ) ,
and I found the exception being catched and logged but not throwed .
Finally, I added an ErrorHandler to Digester in order to be able to know
when an error was been generated
and my problem was solved.
Thanks a lot Reidar!
Regards,
Testa
