Sorry , my languagge italian.

Help help.

Moved from Other IDEs.

What exactly is your question? Evidently your code compiles without errors; does it or doesn't it run without errors?

[jLimone]

my problem .. remove to warnings for code.. solution?
thanks.

[DarrylBurke]

If you need to use a com.sun... proprietary class, then no, you can't remove the warnings.

help my solution?
thanks

[DarrylBurke]

I've already answered that.

Did you write the code or is this something you found and copied without understanding it?

[jLimone]

My code works on java 2.6. With JAVA 2.7 mi says those warnings.

help?

There isn't any Java 2.6 or 2.7, so once again, I have no idea what you're on about.
