hi folks,

i downloaded the latest version from here and saved it at the desktop. then is installed the java from java.sun.com and now i have this java version on my pc:

java version “1.4.2_05”
Java™ 2 Runtime Environment, Standard Edition (build 1.4.2_05-b04)
Java HotSpot™ Client VM (build 1.4.2_05-b04, mixed mode)

my CLASSPATH looks like this:
and i also tried out this:

All applets in browsers work.
i have win xp sp1.

when executing the following line in cmd.exe

c:\Dokumente und Einstellungen\mod>java JBidWatcher-

i get constantly this error:

C:\Dokumente und Einstellungen\mod>java JBidWatcher-
Exception in thread “main” java.lang.NoClassDefFoundError: JBidWatcher-0/9/3/1/j

any ideas what might be wrong?
please help me cause i know the prog and like it very much.

thanks in advance.

The command is:
java -jar JBidWatcher-

The ‘-jar’ tells Java to run it out of the jar file.

You should also be able to double-click on the .jar file, because the standard Java install adds a handler to Windows allowing automatic execution of .jar files via double-click.

Very strange! The Java install should automatically add a .jar handler to your registry.

I don’t have a Windows box handy at this moment, but you should be able to look at your registry for the handler for ‘.jar’ files. (It should be in HKLM.) The .jar entry should have a ‘command’ (or something like that) subtree, which should have ‘open’ (or perhaps just the default?) entry which contains an entry like:

java -jar “%1”

or perhaps
D:\Programme\Java\j2sdk1.4.2_05\bin\java.exe -jar “%1”

If that’s not there, it might have a ‘jarfile’ reference, and then under the same area, you’d find ‘jarfile’, which again would have a command like that in it.

If you chose advanced or custom setup of the Java SDK, you might have not selected ‘associate with .jar files’, or something.

I hope this mostly random collection of thoughts helps…!
