Thank you Isak and Krista!
Both of your solutions work. But now I got another think.
Would you, Isak, or Krista care to post those solutions to the list
for the benefit of the rest of us?[1]
As I told before, I have a "package com.VoglerSoftware.vchat;" command
in my file. After the successful compilation I get now following
message when I try to run the class:
Exception in thread "main" java.lang.NoClassDefFoundError: vchat
(wrong name: com/VoglerSoftware/vchat/vchat)
The way you state things the impression I get is that you have
something like this:
package com.VoglerSoftware.vchat;
public class vchat {
// [...class contents...]
}
This means your fully qualified class name is actually
com.VoglerSoftware.vchat.vchat
and the Preferences method invocation should be
Preferences.userNodeForPackage(com.VoglerSoftware.vchat.vchat.class);
If you were to stay with the conventions as Greg mentioned in
his earlier message
(http://lists.apple.com/archives/Java-dev/2005/May/msg00650.html)
the package would be "com.voglersoftware.vchat" and the class could be
"VChat"
Preferences.userNodeForPackage(com.voglersoftware.vchat.VChat.class);
...
When I remove the package command it works. I have currently my file
in a temporary folder while I am working on it. Do I have to save it
at a special place or do I have to set the CLASSPATH or something like
that?
Don't set CLASSPATH. The use of the CLASSPATH environment variable
has been discouraged by Sun all the way back to Java 1.2

Thank you in advance!

[1] Old-style mailing list "netiquette" said that replies to
questions posted to the mailing list should be sent via email
to the original questioner, who would then summarize the
replies and the solution in a post back to the list. Since
that is now altogether ignored, answers should be posted to
the list for the benefit of everyone. If someone *does*
supply good information in an email reply then that should
be relayed to the list by the author of the original question.

Hello to all,
I hope that my following question is not too stupid.
I created a file vchat.java with the class vchat in it and gave it
the package name com.VoglerSoftware.vchat .
Now I want to get the prefs node for it to save my preferences. I
tried Preferences.userNodeForPackage(com.VoglerSoftware.vchat),
Preferences.userNodeForPackage(VoglerSoftware.vchat) and
Preferences.userNodeForPackage(vchat) and got always an error
message. What do I do wrong? Where is my mistake?
Yours surely
Jens Vogler
