Hi all,

I'm getting the following exception while parsing an .xml file. I don't understand what it means "Content is not allowed in prolog". Can you please help me out.

com.ibatis.dao.client.DaoException: Error while configuring DaoManager. Cause: com.ibatis.common.exception.NestedRuntimeException: Error occurred. Cause: com.ibatis.common.xml.NodeletException: Error parsing XML. Cause: org.xml.sax.SAXParseException: Content is not allowed in prolog.
