Help with an error

[Sparky]

When I compile my code I get: "Build successful"

When I click run (and then "run anyway due to it finding an error) I get:

java.lang.ExceptionInInitializerError
Caused by: java.lang.RuntimeException: Uncompilable source code - package org.jdom does not exist
at v_meter.Main.<clinit>(Main.java:21)
Could not find the main class: v_meter.Main. Program will exit.
Exception in thread "main" Java Result: 1

Here is my code:

package v_meter_xml;

/**
 *

 */

//import javax.xml.parsers.DocumentBuilder;
//import javax.xml.parsers.DocumentBuilderFactory;

import org.jdom.JDOMException;
import org.jdom.input.SAXBuilder;
import org.jdom.Document;
import java.io.IOException;
//import org.w3c.dom.Document;

//import org.w3c.dom.Element;
//import org.w3c.dom.Node;
//import org.w3c.dom.NodeList;
//import java.io.File;

public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here

        try{
SAXBuilder parser = new SAXBuilder();
Document doc = parser.build("http://developerlife.com/xmljavatutorial1/AddressBook.xml");







          
  } catch (Exception e) {
    e.printStackTrace();
  }
 }
  
}

What is the error telling me? How do I fix it?

Thanks

Could not find the main class: v_meter.Main. Program will exit.

Your program is complaining about not being able to find the v_meter.Main class; you're showing us a v_meter_xml.Main class; those two class have nothing to do with eachother.

kind regards,

Is this an error I fix within the program?

I don't see within my program where I am refering to v_meter.Main.

I have:

package v_meter_xml;

and:

public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {

The name of the project is:v_meter_xml

(I'm using NetBeans.)

There's nothing in the code you posted that refers to v_meter.Main, but look at the error message:

java.lang.ExceptionInInitializerError
Caused by: java.lang.RuntimeException: Uncompilable source code - package org.jdom does not exist
at v_meter.Main.<clinit>(Main.java:21)
Could not find the main class: v_meter.Main. Program will exit.
Exception in thread "main" Java Result: 1

It looks like the configuration of your project is such that NB interpreted your click as "run v_meter.Main" (hence the could not find main class message) So, to directly answer your question: it may be nothing wrong within the code, but rather how you compile and run it.

Perhaps you should deal with the first error - the one you didn't post - as that may give more clues.

----------------------

As a general tip, I would consider "clean and rebuild" and also looking at the program configuration to make sure it all looks good.

I don't understand.

When I compile it, I get no errors.

When I run it - it stops and reads that it has encountered a problem, when I click "run anyway" I get the text that I posted in the first post.

What other error do you see that I need to pursue?

Is that all it says: "encountered a problem"?

The runtime error you posted - "Could not find the main class: v_meter.Main" - shows that what you are attempting to run is v_meter.Main.

Are you using an IDE? Which?

I cut and pasted the error - as far as I know that's everything reported/

I will not be behind the computer that has that project until Monday to attempt anymore on that problem.

I'm tempted to start over - I feel like that will do it because it's something stupid on my part - I just didn't see it and as a learning exercise I want to see what I did wrong.
