i dont know how to run a jar file
hi guys i wanna run with commands, a jar file that is generated from netbeans, in netbeans it runs perfectly but if i try to run it with commands "java file.jar" says:
Exception in thread "main" java.lang.NoClassDefFoundError: Paint.jar
and with command "java -jar file.jar":
well the same errors but like 3 or 4 more
and with command "java -jar file.Main"
Failed to load Main-Class manifest attribute from Paint.Main

The command java -versionwill tell you what version of runtime you are using. It is really important
not to use GNU's.
The errors you are reporting are quite strange. Perhaps you should recompile the
whole thing outside of NetBeans. Sun's Tutorial describes how classes can be
combined to form an executable jar file here:
http://java.sun.com/docs/books/tutorial/deployment/jar/index.html
Apart from anything else, using the command line to build the jar file will enable you
to describe your problem more precisely.
On my system there was a link inside /usr/bin that pointed to the GNU runtime. When
I installed java I removed it and replaced it with one that pointed to Sun's.pbrockway@linuxdeskd6off:/usr/bin$ ls -l java*
lrwxrwxrwx 1 root root 22 2007-02-25 08:35 java -> /opt/jdk1.6.0/bin/java
lrwxrwxrwx 1 root root 23 2007-02-25 08:35 javac -> /opt/jdk1.6.0/bin/javac
pbrockway@linuxdeskd6off:/usr/bin$The idea is that when you execute a command like "java" the OS will look on
its path and find /usr/bin/java, it will then follow the link and use the correct java
executable.
