2.使用wtk2.5.2版本（注意该版本为32位，jvm必须使用32位版，配置是选择jvm32位版路径，不然会报错）

3.安装jdk（可以同时安装32位和64位版）

4.安装wtk

自动搜索到32位的jdk

配置wtk安装路径，完成

5.配置eclipse

填写wtk安装路径

配置驱动路径，

Device Management填写wtk安装路径

完成

6.第一个程序

创建项目

src目录创建

import javax.microedition.midlet.MIDletStateChangeException;

public class HelloJ2me extends MIDlet {
        Form form = new Form("HelloJ2me");
        Display display = Display.getDisplay(this);
        public HelloJ2me() {
                // TODO Auto-generated constructor stub
        }

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
                // TODO Auto-generated method stub

}

protected void pauseApp() {
                // TODO Auto-generated method stub

}

protected void startApp() throws MIDletStateChangeException {
                form.append("HelloJ2me");
                display.setCurrent(form);

}

}

运行程序

7.其他问题

报错：

Can't load IA 32-bit .dll on a AMD 64-bit platform

问题所在：

主要是在64位的系统下安装的虚拟机是64位的，而WTK的sublime.dll不能在64位的平台下加载64位的虚拟机，只能加载32位的。由于WTK在安装的时候加载的64虚拟机的地址，它找到的是64位的虚拟机，所以它提示不能加载32位的虚拟机（在目录下没有32的虚拟机）

解决办法：

查看jdk安装的是否是32位版，wtk选择的jdk是否是32位版，二者都必须是32位版
