java-me - Java ME SDK 3 无法启动

Question

我下载并安装了最新的 JDK 和 Java ME SDK。两者似乎都安装得很好。

但是，当我尝试运行 SDK 时，当初始屏幕上的进度条到达“正在启动模块...”时，它会挂起一段时间，然后开始弹出表单的异常:

谷歌透露，我不是唯一遇到这个问题的人，但是我无法找到任何解决方案。

有人对此有任何想法吗？

Answer 1

我在 Win64 专业版上。我有 32 位和 64 位 JDK，发现我必须使用 32 位 JDK，否则我得到了你提到的错误。

我发现 installDir\bin 和 installDir\toolbar\bin 中有一个名为“java”的文件具有 JDK 的路径，因此我将两者都更新为 32 位 JDK，然后它就可以工作了。我希望这对您或其他人有所帮助。
