I have installed Netbeans 7.0 (in window xp SP3) and I also installed "Wireless Toolkit 2.5".
But when I open Netbeans
File->New Project
then there is only option for Java SE and Java EE.
Not for Java ME.
I also try
Tools-> Plugin -> and search for Java ME
but I was not able to find "Java ME".
At first install 'Mobility' plugin for NetBeans IDE for J2ME development. You can do this from
Tools
>Plugins
> (Select and install). Then DO this.. In netbeans,Tools
>Java Platforms
>SelectAdd Platform
>SelectJava ME MIDP platform emulator
> select the one you installed now (Wireless Toolkit 2.5(location))
