why is this happening? i didnt do anything, i only just add a menu bar item and attach an event but this happen. then i undo adding of that menu item, but it still exist.
this error happen in my last project in netbeans 6.9, then i make another project and transfer some components and it works, while i was continuing to add the said
menu item, that error appear.
db there is a package, and MainClass is my main.
Caused by: java.lang.ClassNotFoundException: db.MainClass
at java.security.AccessController.doPrivileged(Native Method)
Could not find the main class: db.MainClass. Program will exit.
Exception in thread "main" Java Result: 1
I don't know about netbeans, but in Eclipse if you build the project it generates all the class files. Perhaps netbeans has something similar to "build" the project?

yes it has build and clean and build, when i clean and build, the class are there, but when i run the program using right clicking on the MainClass node > run, the classes disappear in the folder when i look to it, it gave me the same error.
