[Eclipse 3.1 RC1+ VE 2.1 M1] Why do I get a "serializable class error" when my class doesn [message #205925]

Hi,

I've just updated Eclipse with all the latest, and now I'm getting an error:

"The serializable class MyJFrame does not declare a static final
serialVersionUID field of type long."

Why do I get this error since the offending class doesn't implement the
serializable interface? It is just a 'visual class' (JFrame) created
using the wizard? Interestingly it builds and runs just fine.

Thanks very much for your help.
PretzelX.

Looking at the JDK documentation, I see that the Component class does
implement the Serializable interface. Silly me! All the other IDEs
I've been used either haven't been smart enough or have been ignoring
this warning.

Now I know...

PretzelX,
Super class (any) implement serializable.
You can suppress warning in preferences (window-preferences - java)

Or you can use Ctrl+1 to generate a SUID or suppress the warning by adding
the annotation @SuppressWarnings("serializable").

Cheers
