I like install nokia sdk into wtklib of WTK 2.2, so I can use it by WTK 2.2. You know, almost all IDE support WTK2.2 if it support j2me development. In this way, I select nokia emulator as working device, and the library and emulator should switch to right ones automticly. I use Jbuilder, netbeans, both so. But for Intellij IDEA 5.0, it seems not work.
