Hallo,

ich habe jetzt versucht, einen .jar-File herzustellen.

jar cf my.jar input HelloWorldSwing.java

Da kommt auch was raus, aber weder mit rechterMaus "starten mit Java 6 Runtime" noch via Konsole "java -jar my.jar" gehts. Bzw. bei der Konsole kommt: "jar cf jar-file input-file(s)

"Failed to load Main-Class manifest attribute from jarfile.jar"

• This example, like all Swing examples, exists in a package:
• in this case, the "start" package.
• If you are using an IDE, such as NetBeans, this should work
• seamlessly.  If you are compiling and running the examples
• from the command-line, this may be confusing if you aren't
• used to using named packages.  In most cases,
• the quick and dirty solution is to delete or comment out
• the "package" line from all the source files and the code
• should work as expected.  For an explanation of how to
• use the Swing examples as-is from the command line, see
• http://download.oracle.com/javase/javatutorials/tutorial/uiswing/start/compile.html#package

• HelloWorldSwing.java requires no other files.
