[jdom-interest] testing for existance of xml file

[Bartley, Chris P]

Perhaps something like this:

    File xmlFile = new File("/usr/local/tomcat/myfile2.xml")
    if (xmlFile.exists())
       {
       try
          {
	   ...
          Document aDocument = builder.build(xmlFile);
          ...
          }
       }
    else
       {
       ...
       }
