Re: [platform-swt-dev] java.lang.NoClassDefFoundError when running a standalone SWT application
|
David,
Thank you for letting me know two kinds of advices.
As I have just started with learning eclipse project, I could not get
well-understanding of how to use.
In future, I will use the newsgroups for such as basic questions and got to

Thank you for your cooperation.
