Hi all,
I am writing my own HTML parser and replace the original parser with it. When the parser is running, it needs to access to some local files and databases. When I downloaded a single HTML page like http://www.apache.org to local drive and parse it, I got no problem. But when I parsed the web page on the fly, there are exceptions thrown out. The log file shows the following: 2011-04-30 03:23:31,004 INFO html.MyHtmlParser - Inside MyHtmlParser! 2011-04-30 03:23:31,035 WARN parse.ParseUtil - Unable to successfully parse content http://www.apache.org/ of type text/html When I debugged it, my debug process was brought to the FutureTask.class, and the source of the .class file begins with the following: /* * @(#)FutureTask.java 1.14 06/07/13 * * Copyright 2006 Sun Microsystems, Inc.

Will singleton be the answer? If so, then how? Much appreciated if you could lend me a hand. Jeff
