+2  A: 

You are invoking

Document doc = db.parse(eventXml);

with eventXml apparently being a string of XML data.

However, the method DocumentBuilder.parse(String) expects a URI to load the XML from. That's why you get a MalformedURLException: Java tries to use your XML as an URI.

You want DocumentBuilder.parse(InputSource), or DocumentBuilder.parse(InputStream). The InputStream can be created from your String/StringBuffer using e.g.

new InputSource(new StringReader(xmlString))

(untested).

+3  A: 

parse() doesn't take actual XML as a parameter, instead it takes URL to a document.

You should use DocumentBuilder.parse(new StringBufferInputStream(eventXml));

(+1) .. as clearly written in the JavaDoc for DocumentBuilder#parse. If still in doubt, google for 'DocumentBuilder' and follow the first link.

+1  A: 

You have posted so much content but nothing that can help any reader to see what you were trying to do. If your problem is just that XML parsing is giving you a problem then check that your XML is well-formed.
