package problem

[Je Th]

Im lost with package problem. Why do I get a comipler error on DOMParser, I found this on the Java Ranach wkiki FAQ - XML. Do I need something more then just this code?

import org.apache.xerces.parsers.DOMParser;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
import org.xml.sax.SAXNotRecognizedException;
import org.xml.sax.SAXNotSupportedException;
import java.io.IOException; 
public class SchemaValidationExample {
     public static void main(String args[]) {
DOMParser parser = new DOMParser();
Document doc = null;
try {    
parser.setFeature("http://xml.org/sax/features/validation", true);     
parser.setFeature("http://apache.org/xml/features/validation/schema", true);     
parser.parse("data.xml");    
doc = parser.getDocument();
} catch (IOException e) {    
System.out.println("Could not read file: " + e.getMessage());
} catch (SAXNotRecognizedException e) {    
System.out.println("Feature not recognized: " + e.getMessage());
} catch (SAXNotSupportedException e) {    
System.out.println("Feature not supported: " + e.getMessage());
} catch (SAXException e) {    
System.out.print("Parsing XML failed due to a " + e.getClass().getName() + ":");    
System.out.println(e.getMessage());
}    
}
}

Make sure you are including all the relevant JAR files in your classpath when you run the code.
If you're still having problems, post a copy of the compiler's error messages. That will help us to work out what's going on.

Thats the "tricky" part "package org.apache.xerces.parsers does not exist" it the compiler error.

Download the latest Xerces JARs from http://gump.covalent.net/jars/latest/xml-xerces2/ and add them to your classpath.

I cant mange to add the jars to my classpath. How do i do it? Create a enviroment variable called "CLASSPATH" and value "C:\myJarFiles\xercesImpl.jar;C:\myJarFiles\xmlParserAPIs.jar;" or is it more to it?

Check out HowToSetTheClasspath in the Java Ranch FAQ.

I mange to install the jars to my classpath but now Im getting this error:
Exception in thread "main" java.lang.NoClassDefFoundError: SchemeValidationExample
Any one got a clue?

[Dirk Schreckmann]

Exactly what does your CLASSPATH setting look like?
Did you forget to include a . in your CLASSPATH?

I dont got any classpath i just copied the jar-files to the jre\lib\ext-folder. So I can compile it. Now its working, but not my CLASSPATH.. Its strange. If I remove the jar-files from the ext-folder, then it wont work. This is how my CLASSPATH looks like ".;C:\java\xerces-2_6_0\xercesImpl.jar;C:\java\xerces-2_6_0\xmlParserAPIs.jar", and Im using WinXP.
