J2ME technology originated from Java, so there is also the advantage of JVM, which can be transplanted on the platform of Java, but now J2ME technology is very bad on cross-platform, let's take a look at the reason:
1, the screen size of the phone is not:
This is mainly made on the interface.
If you are using an advanced user interface, if you doing application development or user login, the user registers such a general function, there is no problem.
If you are using a low-level user interface, such as what you do is a game, then you need to consider this problem.
2, the manufacturer's expansion API does not unify:
For example, NOKIA's extended API library UI series, on other mobile phones or not implement, or the package name is different.
3. BUG implemented on the mobile phone platform:
For example, NOKIA's 7650 has bugs on a double buffer, then software running on such models cannot use dual buffers. Some bugs on other NOKIAs can be found:

4, mobile phone performance problem.
Different mobile phone available memory, the largest JAR files have requirements, such as the maximum JAR file supported by most mobile phones of NOKIA S40 for 64K, maximum available content is 210K.
So the current mobile phone software, especially the game provides support, and has the existence of mobile game porters.
