我已经安装了:
-eclipse Indigo 3.7,
-JDK 1.7 in /usr/lib/jvm` and,
-Tomcat 7
-Spring framework 2.5.6
我正在尝试做一个教程 found here:
为此，我创建了一个使用 «spring MVC 框架» 完成的 «dynamic web project»。我试图通过 «在服务器上运行» 来运行它，但我收到了 «HTTP 404 错误:(/SpringMVC/) 资源不可用»。我真的不知道我错过了什么。提前感谢您的帮助。
这些是我最初包含在项目中的库:
-jakarta-commons/commons-logging.jar
-mysql-connector-java-5.1.18
-j2ee/jstl.jar
-log4j/log4j-1.2.14.jar
-jakarta-taglibs/standard.jar
-dist/spring.jar
-dist/modules/spring-webmvc.jar
我刚刚添加了 spring-web.jar 库。
这是我收到的新错误消息:

最佳答案
java.lang.ClassNotFoundException:org.springframework.web.context.ContextLoaderListener
似乎您没有将 spring-web.jar 依赖项包含到类路径(在 WEB-INF/lib 中)。
关于eclipse - HTTP 404 错误 : (/SpringMVC/) ressource unavailable，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/8220965/
