XML JDOM problems
Hi all,
I have some problem in one of my xml file which value "&" in it.
I am using JDOM API to extract xml data to database below is code:
the error line is in SAXBuilder builder = new SAXBuilder(); code.
Any one have any suggestion or ideas how to solve it ?
Thanks

HttpServletResponse response) {
int dispatchState = 0;

SAXBuilder builder = new SAXBuilder();

File [] files = file.listFiles();
