XDoclet类路径缺少J2EE类（MyEclipse）

Question

我无法找到解决此问题的方法。

当我尝试运行ejbdoclet时，我收到错误

XDoclet classpath missing J2EE classes

XDoclet类路径在哪里以及它缺少的J2EE类在哪里？这里有没有人有任何想法？我正在使用MyEclipse和Ant。

BUILD FAILED

您必须缺少路径中的某些jar文件，或者build.xml中的路径是错误的。检查build.xml。 我有一个类似的问题，但意识到我在路径上有一个错字。

<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}"/>

我的树脂指向错误的位置。 我收到以下错误：
