在服务器上部署War之后，出现以下错误，

我已经检查了WEB-INF / lib文件夹下的commons-beanutils.jar，它在那里。 我已将其包含在build.xml中的类路径下。

还有什么我想念的吗？

我认为您的服务器在org.apache.commons.beanutils包中找不到Converter类。还请检查您的项目构建路径，以查看是否存在org.apache.commons.beanutils.converter类。 如果不是，那么下载最新的Commons-Utils jar并将其添加到您的lib文件夹中。 您可以在[此处] http://commons.apache.org/proper/commons-beanutils/index.html找到链接
