[jdom-interest] Newbie can't parse document!

[Matthew MacKenzie]

It looks like the underlying parser tries to grab the external DTD even if
it has no plans for using it.  The connection is likely failing because a
http proxy isn't set or something.  Maybe JDOM needs to set a variable in
the underlying parser to disable resolution of external entities in certain
cases??

  Hi, I am new to using JDOM. I think I have done everything correctly to
create a SAXBuilder but I am getting an exception. I created a
FileInputStream and passing a File object, the same that I am passing to the
SAXBuilder, I can read and print the file to the screen.

  My code is as follows:

    String
directory="C:\\JBuilder4\\Projects\\pwWorkRequest\\src\\WEB-INF\\";
    String file="web.xml";

    File f=new File(directory + file);
    FileInputStream fis=new FileInputStream(f);
    int n;
    while ((n=fis.available()) >0)
      {
        byte[] b=new byte[n];
        int results=fis.read(b);
        if(results==-1) break;
        String s=new String(b);
        System.out.print(s);
      }

  This works OK.

  But this causes an exception:

    SAXBuilder builder=new SAXBuilder(false);
    Document doc=builder.build(f);

  The exception  message is:

  java.sun.com: java.sun.com

  The printstack trace:

  Any help in figuring out what is going on is appreciated.
