Redirecting output of java program to file

[dewitrydan]

Hey there.
I am following a tutorial on XML with java.
It says to run the program from command prompt with the following command:

java RssStarter > feed.rss


But I get the following error:

D:\Users\test\Desktop\JAVA STUFF\Eclipse_workspace\RssStarter\bin>java RssS
r > feed.rss
Exception in thread "main" java.lang.NoClassDefFoundError: RssStarter
Caused by: java.lang.ClassNotFoundException: RssStarter
        at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: RssStarter.  Program will exit.

D:\Users\test\Desktop\JAVA STUFF\Eclipse_workspace\RssStarter\bin>

Here is the code:

import nu.xom.*;

public class RssStarter {
    public static void main(String[] arguments) {
        // create an <rss> element to serve as the document's root
        Element rss = new Element("rss");
        
        // add a version attribute to the element
        Attribute version = new Attribute("version", "2.0");
        rss.addAttribute(version);
        // create a <channel> element and make it a child of <rss>
        Element channel = new Element("channel");
        rss.appendChild(channel);
        // create the channel's <title>
        Element title = new Element("title");
        Text titleText = new Text("Workbench");
        title.appendChild(titleText);
        channel.appendChild(title);
        // create the channel's <link>
        Element link = new Element("link");
        Text linkText = new Text("http://www.cadenhead.org/workbench/");
        link.appendChild(linkText);
        channel.appendChild(link);
        
        // create a new document with <rss> as the root element
        Document doc = new Document(rss);
        
        // Display the XML document
        System.out.println(doc.toXML());
    }
}

Can someone tell me whats wrong? Thanks

my question is: why you dont use then eclipse to run your code? you can define program arguments in elclipse too : Run --> Run Configurations... --> in the arguments tab.

I dont know the XML libraray nu.xom, but in your program, you dont use the arguments array ? ;/

doc.toXML() is only created a string containing the xml or? so you have to write it in a file by yourself?!

can you give us the link to the tutorial?

to your problem: do you have compiled the class? :)

What is the class's package?

I've uploaded the bit of the tutorial.

Yep I was running the compiled class thanks

Make sure RssStarter.class really is in the directory where you are executing java.exe. (Sorry for mentioning this, but its the place to start.)

Then make sure that the classpath being used includes this directory. Something like:

> java -cp .;<path_to_directory_containing_nu> RssStarter

I've put path_to_..., but it might be a jar file that contains the nu.xom classes. The point is they have to found by java.exe and using a "bare" java command will leave you at the mercy of OS variable settings.
