However, when i'm trying to code the ActionPerformed() part it throws an error about JButton not being visible.

问题 after everything was running smooth in my earlier deployment environments, I've moved my site onto a server 2008 R2 box... I have a silverlight enabled wcf service (in IIS) which calls another external service, but my wcf service is unable to find the certificate that it needs to access the external service.

问题 How do you make a Javascript private method that is not redefined each time you call the constructor ?

I was thinking maybe a function declaration (i.e. function name() , as opposed to function expression var name = function() ) would do the trick, but how can I be sure that the following code only declares my function once ?
