I have created so many J2ME applications on NetBeans. now i want to create
J2ME applications in Eclipse instead of NetBeans.
so I am new to Eclipse and I installed the MTJ Plug-in in Eclipse 3.7.2 Indigo
as well as the J2ME Wireless Toolkit for devices.
I can create applications and run them then, but when I use LWUIT.jar and
make a simple Hello World project, then I cannot create it.
When I choose the compiler level (Complier complaint level in Java
), then I got an exception, for example,
Running with storage root DefaultColorPhone java.lang.NoClassDefFoundError: com/sun/lwuit/Display at HelloMidlet.startApp(+1) at javax.microedition.midlet.MIDletProxy.startApp(+7) at com.sun.midp.midlet.Scheduler.schedule(+270) at com.sun.midp.main.Main.runLocalClass(+28) at com.sun.midp.main.Main.main(+116) Execution completed. 709909 bytecodes executed 4 thread switches 742 classes in the system (including system classes) 3658 dynamic objects allocated (101416 bytes) 2 garbage collections (87640 bytes collected)
and when I set another compiler level to another, e.g. 1.4, 1.5, 1.6 or 1.7, then I
got an exception for example
