The CrE-ME 4 VM implements the J2ME CDC/Personal Profile 1.0 specification, replacing the Personal Java 3.1 standard of CrEme 3. Notably, Swing is supported. The default and preferred graphics library is based on the Truffle implementation of AWT. It is highly optimized and fully supports non-western languages. The Tiny AWT is offered as an alternative.
LZ先了解一下J2ME的CLDC与CDC的区别吧。。。。。还有,Wince(非WM)上最好的J2ME虚拟机是phoneme和IBM J9,如果你的WINCE系统通用性好的话,试试JAVA FX FOR MOBILE,RP好的话也许能够使用。
