who execute without using package ?

[haux]

Hello

i have already used JBuilder (to compile and excute my progs), and all time
i create a new package so all classes have this in top :

package MyPackage;

but when i excecute it with consol mode (without JBuilder4) i have this exception :

#java MyProg
Exception in thread "main java.lang.NoClassDefFoundError : MyProg (wrong name:
myprog/MyProg)
.................(and other error messages)

Can somebody tell me what i have missed

thanks for all.

How are you executing it?

When you place a class in a package, you can no longer invoke it using

java <classname>

instead, you have to use

java <packagename>.<classname>

So, for instance here is a simple class:

<begin Helloworld.java>

package helloworld;

public class Hellowrld {
public static void main (String args []) {
System.out.println(&quot;Helloworld!&quot;
}
}
<end Helloworld.java>

Now, after compiling, I will either have to have the directory helloworld in my classpath or I will have to be in the parent directory of the helloworld directory and I would type the following to run this program:

java helloworld.Hellworld

Hope this helps,

Charles
