I am reading the XML file and putting document object into the static HashMap when I read first time. The next time onwards I am getting the document object from HashMap. It seems some how the document object is getting corrupted, results I am getting the following error(not all the time). Is there anyway check the document is valid? So that I can read XML agian and put it into HashMap. I am using WAS.

Error :

org.xml.sax.SAXParseException: " </
>" expected.
