Hello,
I am trying to develop a web application in Java, using NetBeans 6.5.1.
NetBeans installed Tomcat 6.0.18.
I am using java 1.6 update 11.
In my application I have a thread that loops and reads a configuration file
and
if it finds any changes in configuration it takes some action.
The configuration file is in XML form and it is being accessed (read/write)
using java.util.Properties class.
When the thread starts, an object of the Properties class is created with
the
following code:
Properties props = new Properties();
File file = new File("a file");
if (file.exists()) {
try {
props.loadFromXML(new FileInputStream(file));
} catch (Exception e) {
System.out.println(e.getMessage());
}
At the moment that props.loadFromXML method is called I get the following
output on the console:

In the lib directory of tomcat both javax.xml.parsers and xerces jar files
exists.
Thanks in advanced.
