我是新的Struts，我试图运行一个样本登录Web应用程序使用Struts，但我无法得到结果，由于(javax.servlet.UnavailableException: Missing configuration resource for path /WEB-INF/struts-config.xml)错误。我已经做了一切在配置在Eclipse的Struts。我甚至不知道什么是异常？请任何人帮助我
我得到的错误是：

您已将Web应用程序配置为使用
struts-config.xml字符串
但是在指定的文件夹中没有这样的文件名。确保文件存在，或者如果你为struts配置文件使用另一个名称，你可以改变这个init param值来反映文件的可用性。如果你有多个配置文件，每个配置文件都有一个模块，你可以用逗号来分隔名称。

你需要从apache lib 文件夹中添加 servlet-api.jar。你需要在java resources下的 src 文件夹中包含 struts.xml 文件夹。

1)你提到你的struts.xml文件名为struts-struts.xml，但在init-param中你写为struts-config.xml。请正确检查名称。
2)或者（常见问题）因为你的struts xml文件中缺少DTD标签。尝试将此代码添加到struts-config.xml中的
<struts-config>标签上方。<!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://struts.apache.org/dtds/struts-config_1_3.dtd">个nuypyhwy4#
确保
struts-config.xml位于WEB-INF文件夹中。同样，hibernate.cfg.xml也应该位于适当的位置（如果您正在使用它）。
