在观看Roo Google IO之后，我决定使用本教程进行尝试，但是在尝试创建 Selenium 测试时我遇到了困难。

~.web roo> selenium test --controller ~.web.PizzaOrderController
Created SRC_MAIN_WEBAPP/selenium
Created SRC_MAIN_WEBAPP/selenium/test-pizzaorder.xhtml
Created SRC_MAIN_WEBAPP/selenium/test-suite.xhtml
Undo create SRC_MAIN_WEBAPP/selenium/test-suite.xhtml
Undo create SRC_MAIN_WEBAPP/selenium/test-pizzaorder.xhtml
Undo create SRC_MAIN_WEBAPP/selenium
com.sun.org.apache.xerces.internal.dom.DeferredCommentImpl cannot be cast to org.w3c.dom.Element

这个论坛上的一个人建议从类路径中删除 Xerces，因为 Java 6 有自己的基于Xerces的 XML 解析器。但是，我还没有找到从classpath中删除某些内容的明确方法，只能设置它（我认为每次都会很乏味）。

有谁知道从类路径中删除 jar的明确方法？有没有人遇到过这个 Roo 问题并以另一种方式解决？

更新

根据要求，这是更详细的输出：

roo> development mode
Development mode set to true

您能否输入“开发模式”，按回车键，然后重新运行 Selenium 命令并包含以下更详细的堆栈跟踪？
