 |
|
Hi,
I'm not sure if this question belongs here, but since I believe that the problem might be caused due to configuration issues I post it anyway. So here is my problem:
Starting to learn Java by a book I just wrote the following HelloWorld program:
| Code: |
public class HelloWorld extends Object {
public static void main (String args[]) {
System.out.print ("Hello World");
}
}
|
saved it as HelloWorld.java, compiled it without problems using blackdown-jdk-1.3.1.
But when I start the program with java HelloWorld I get the following message:
Exception in thread "main" java.lang.NoClassDefFoundError: HelloWorld
In case that the CLASSPATH has something to do with it, an echo $CLASSPATH returns:
/opt/blackdown-jdk-1.3.1/lib/rt.jar:/opt/saxon/saxon.jar:/opt/xalan-j_2_3_1/bin/xercesImpl.jar:/opt/xalan-j_2_3_1/bin/xalan.jar:/opt/xalan-j_2_3_1/bin/xalansamples.jar:/opt/xerces-1_4_4/xerces.jar:/opt/xerces-1_4_4/xercesSamples.jar
Any suggestion to help me out with this problem is welcome,
Alex |

If the .class file is in your current directory then you need the current directory in the classpath
e.g.
export CLASSPATH=.:$CLASSPATH
then try again |
