Subject Re: Wierd problem while unmarshalling
Date Tue, 13 Sep 2005 05:42:23 GMT
Hi

Any updates on this?

Now a days Im getting this error

SAXException: Parsing Error : Content is not allowed in prolog

According to the documentation it says

That's a parser error, not a JDOM error.  Either your content is
malformed (you didn't send it in so we can't know) or your parser is
broken.

Any more updates on this??
