解决 JBoss-IDE 打开 XDoclet Configurations 出错的问题

我安装的 Eclipse 是 3.2RC6 版的,JBoss-IDE 是 1.5.1 GA 版本,在建立 J2EE 工程时,打开 Properties 中的 XDoclet Configurations 时出现了 "xDoclet the currently displayed page contains invalid values." 的错误,后来查了 eclipse 的 log 文件,发现以下错误:

!ENTRY org.eclipse.jface 4 2 2006-05-29 17:32:13.437
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.jface".

原来是找不到类:org/eclipse/jdt/internal/ui/viewsupport/ListContentProvider,后来到 eclipse/plugins/org.eclipse.jdt.ui_3.2.0.v20060428-1300.jar 文件中查看,果然是缺少了 ListContentProvider 类文件,然后我到 google 按 org/eclipse/jdt/internal/ui/viewsupport/ListContentProvider 关键字查找,找到了 http://kickjava.com/src/org/eclipse/jdt/internal/ui/viewsupport/ListContentProvider.java.htm ,是 java 开放源码的网站,可以找到几乎所有的JAVA开源项目的源代码,这个连接就是 ListContentProvider 这个类的源文件,只要复制上面的代码,然后编译就行了(当然要包含 eclipse/plugins 下面的jar文件啦),然后把生成的 class 文件放到 eclipse/plugins/org.eclipse.jdt.ui_3.2.0.v20060428-1300.jar 这个jar文件的对应目录就行了.

OK,问题就这么简单.
