我找不到这个问题的解决方案。

当我尝试运行 ejbdoclet 时，出现错误

XDoclet classpath missing J2EE classes

XDoclet 类路径在哪里，它缺少的 J2EE 类在哪里？这里有人有什么想法吗？我正在使用 MyEclipse 和 Ant。

完整跟踪：

您的路径中一定缺少一些 jar 文件，或者您在 build.xml 中的路径是错误的。检查您的 build.xml。我有一个类似的问题，但意识到我在路径中有一个错字。

<pathelement location="${resin.home}/lib/ejb-15.jar" />
<pathelement location="${resin.home}/lib/ejb-20.jar" />
<pathelement location="${resin.home}/lib/ejb-30.jar" />
<pathelement location="${build}"/>

我的resin.home 指向了错误的位置。我收到以下错误：
