Eclipse 重构失败 -> 不断抛出异常！

我正在使用 Eclipse Helios，对于跨多个文件的每次重构，它显然都会失败！什么都没发生。在检查日志时，我看到了以下错误：

这个错误对我来说没有多大意义，无法导航甚至“尝试”修复它。对于文件/方法的“本地”重构，它似乎工作得很好。我尝试过解决这个问题，但只是惊呆了！我倾向于经常使用重构功能。我正在使用 J2EE + Glassfish v3。我在构建路径上有 freemarker、restlet 和 DBUtils 的 JAR。

有任何想法吗？有没有人遇到（并解决了：）这个问题？

提前致谢！

看起来像是插件问题。根本的例外是，

Caused by: java.lang.NoClassDefFoundError: org/eclipse/jst/jsp/core/internal/java/search/JSPIndexManager

这意味着找不到一些应该存在的类。您最近安装/删除了插件吗？您可能需要重新安装 eclipse。
