Does anyone know what might cause this error which prevents my program from
staring up.

Exception in thread "main" java.util.zip.ZipException: The system cannot
find the file specified
at java.util.zip.ZipFile.open(Native Method)
at java.util.zip.ZipFile.<init>(Unknown Source)
at java.util.jar.JarFile.<init>(Unknown Source)
at java.util.jar.JarFile.<init>(Unknown Source)

I don't get the problem on my system (Windows 2000) but one of my users has
reported it on Windows 98 and I cannot reproduce it.

Thanks for any ideas,

Martin

When I put the wrong program name in under windows 2000 I get:

Exception in thread "main" java.lang.NoClassDefFoundError:
NoSuchJar/mjbWorld

I guess the error messages under windows 98 must be different? (although in
both cases I found the word "main" confusing because it implied to me that
my program had been started.

Also, I have been running the program as follows:

java mjbWorld.mjbWorld

i.e. the name after the dot specifies the file inside the jar to use, if I
change it to include the .jar extension i.e.:

java mjbWorld.jar.mjbWorld

then I get:

Exception in thread "main" java.lang.NoClassDefFoundError:
NoSuchJar/jar/mjbWorld

Can anyone suggest a form that will work on all operating systems and
configurations?

Thank you for the link to http://mindprod.com/classpath.html , it looks
useful, perhaps it will answer my question?

Thank you for your helpful replies,
