Re:Re:Executing SC from Netbeans

Hello !


Thanks for your response, I've resolved my problem.

But now in a same way, I want to implement a Timer into my
RSS  
protocol using the javax.swing.Timer
package, included into the JDK since version 1.4 (according
to  
java.sun.com website).
No problem when compiling, but always the error message
"java.lang.NoClassDefFoundError
javax/swing/Timer".
Logically, I should include swing.jar into the building of
my bundle,  
but I can't find the file swing.jar
nowhere...

What do you think about it?

Thanks.

Jean-Albert.

Hello Jean-Albert,

Swing is part of the JRE so you won't need to explicitly
include it in 
your bundle.

However, I suspect you might have forgotten to add
javax.swing to the 
list of imported packages in your manifest file. This would
explain the 
NoClassDefFoundError that you are receiving.

As a side note, unless you are planning on using the timer
for some UI 
related management, it might be a better idea to use the
java.util.Timer 
instead of the Swing one. If you'd like to read more on the
difference 
between the two, have a look at this article:


http://java.sun.com/products/jfc/tsc/articles/timer/

Don't hesitate in case other questions arise.

Cheers
Emil
