HI All
         I am using Xalan2.7.0 for transformation. I am getting a
"MalformedByteSequenceException:: Invalid byte 2 of 2-byte UTF-8 sequence"
exception while transforming a xml file. The encoding defined in input xml
is ISO-8859-1.  Complete stack trace is :::
javax.xml.transform.TransformerException:

2-byte UTF-8 sequence.

What can be the possible cause for this exception ?

Thanks & Regards
