[求助]eclipse3.2下的SpringIDE插件出错

我在这个地址下载的SpingIDE插件
http://springide-eclip.sourceforge.net/updatesite/

我只下载了updatesite_1.2.2.zip这个包，解压缩后的目录结构就是plugins、features、site.xml这三个文件（夹）
我用的是外挂式安装，重启eclipse后，Window->Show View->Other->Spring IDE->Spring Beans，就会弹出如下的
告警框：An error has occurred. See error log for more details. 查看详细信息如下：

请问这里有谁成功安装过SpringIDE的朋友，告诉一下是什么原因，你们是怎么安装的？谢谢！
----------------解决方案--------------------------------------------------------
不懂EC
建议使用NB
----------------解决方案--------------------------------------------------------

为什么建议使用NB？现在企业中使用NB的并不多啊，绝大部分用的都是Jbuider和Eclipse啊

----------------解决方案--------------------------------------------------------
是吗?
NB不多只代表它以前做得不太好,现在NB可是真正的牛B了
