[jdom-interest] Re: jdom 1.0 XMLOutputter -- problems

[Edelson, Justin]

Here's some basic document creation code:
	Document document = new Document();
	Element rootElement = new Element("root");
	document.setRootElement(rootElement);
	Element childElement = new Element("child");
	rootElement.addContent(childElement);
	childElement.setText("some text"); 

Same code all on one line:
	Document doc2 = new Document().setRootElement(new
Element("root").addContent(new Element("child").setText("some text")));

As for your other issues, these really don't have anything to do with
jdom. I suggest you read up on the importance of the classpath to figure
out why your are getting a ClassNotFoundException. Comparing
command-line Java with Tomcat isn't really a valid comparison as Tomcat
is a container that uses custom classloaders based on a directory
structure.

As for your FileNotFoundException, any reason to think this isn't just
because this file doesn't exist?

yes and yes....

downloaded just this weekend, downloaded jdom-1.0.zip...

ok, look at this small example, from
http://www.javaworld.com/javaworld/jw-05-2000/jw-0518-jdom-p2.html

import java.io.*;
import org.jdom.*;
import org.jdom.input.SAXBuilder;
import org.jdom.input.*;
import org.jdom.output.*;

public class PrettyPrinter {
    public static void main(String[] args) {
     //    Assume filename argument
     //    String filename = args[0];
	  String filename = "myFile";

         try {
             // Build the document with SAX and Xerces, no validation
             SAXBuilder builder = new SAXBuilder();
             // Create the document
             Document doc = builder.build(new File(filename));

             // Output the document, use standard formatter
             XMLOutputter fmt = new XMLOutputter();
             fmt.output(doc, System.out);
         } catch (Exception e) {
             e.printStackTrace();
         }
     }
}

this compiles fine but when run it with just this command:

     java PrettyPrinter

get following error: Exception in thread "main" 
java.lang.NoClassDefFoundError: org/jdom/input/SAXBui lder (I don't get
this.. if this class cannot be found how come it compiled fine?  do you
need to always indicate cp when running classes with third-party API's?
I don't have to do this w/Tomcat..)

if I run it like this:  java -cp jdom.jar;. PrettyPrinter

get this error:

Documents\xslt\myFile (The system cannot find the file specified)

I would LOVE to have some code to just create a simple xml file with
JDOM.. (still don't know if SAX or DOM is best...)  'parsing' means to
READ an xml file, so if you're CREATING an xml file you don't need to
parse right?  sorry if these questions sound stupid, am just beginning
to learn all this stuff.. finally know diff betw. SAX and DOM... :)

thank you very much..

Frances
