Java Programming

Hi,

I am using JAXP to transform xml message with xslt.

It worked fine when my input xml file was in UTF-8 encoding as it has japanese charaters.

Now I am trying to transform it without UTF-8 as in my original scenario.
I got the sample file from the source system.
There is no encoding specified in XML prolog.

Now when I try to read this file, I get this error:

ERROR: 'Invalid byte 1 of 1-byte UTF-8 sequence.'
ERROR: 'com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: Invalid
byte 1 of 1-byte UTF-8 sequence.'

1. Is there any way to figure out in which encoding the source system is sending xml message?
2. If there is, how to read the xml message with this encoding?

Regards.
