[问题]求救：JDK6+WTK1.5.1+Eclipse3.2编写j2me时不能运行

洛泺 · #1

已经装好了JDK、WTK和Eclipseme
Eclipse里已经设置好WTK的路径

在编写j2ME程序时无法运行编写的程序，一运行控制台就出现下面代码：

希望高手帮忙解决一下，谢谢了

你的系统是6.06,6.10还是7.04，WTK是中文的吗？

洛泺 · #3

我的系统是7.04
我刚学用Ubuntu，不知怎在Ununtu直接启动WTK，所以不太清楚是中文还是英文，不过wtk1.5.1好像还没有中文版吧。
我的WTK是直接在SUN主页下的：https://sdlc4d.sun.com/ECom/EComActionS ... 6D90267DA8

在GOOGLE搜WTK／J2ME UBUNTU，好像很少关于这方面的问题~

我也遇到同样问题哎。。

breakstring · #5

唉。。。。原来不是我一个人这个问题吖。。。

breakstring · #6

找到一个暂时解决方法，写一个脚本文件，把字符集临时变成英文然后再打开Netbeans就好了：

代码：全选

#!/bin/bash
declare -x LANG="en_US.UTF-8"
declare -x LANGUAGE="en_US"
/home/yourname/netbeans-5.5.1/bin/netbeans

我相信Eclipse也可以这样解决
不过唯一的遗憾就是模拟器中无法显示中文了
