关于eclipse下VE插件的安装问题

我已经在网上找了很多文章关于如何成功安装VE插件的问题,但是我努力了2天,最终还是失败.
我安的是eclipse 3.0版本,下载了各个插件以后都安装上了,也看到了visual Class这个类.我创建了一个该类,但是当界面显示时候eclipse就搜索VE的各个包,期间就出现
An internal error occurred during: "Create Remote VM for Visual Editor for Java".
  An internal error occurred during: "Create Remote VM for Visual Editor for Java".An internal error occurred during: "Create Remote VM for Visual Editor for Java".
An internal error occurred during: "Create Remote VM for Visual Editor for Java".
