Eclipse HTTP 404错误：（/SpringMVC/）ressource不可用

我安装了：

-eclipse Indigo 3.7,
-JDK 1.7 in /usr/lib/jvm` and,
-Tomcat 7
-Spring framework 2.5.6

我想做一个教程

为此，我用«spring MVC framework»创建了一个«

动态web项目

»。我试图在服务器上运行它，但出现了一个«

HTTP404错误：（/SpringMVC/）ressource不可用

»。我真的不知道我错过了什么。提前感谢您的帮助

这些是我最初在项目中包括的图书馆：

-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

springweb.jar

库

这是我收到的新错误消息：

似乎您没有将spring-web.jar依赖项包含到类路径中（在web-INF/lib中）。

嗨，Gabriel，谢谢您的回答。我已使用新的错误消息编辑了我的初始消息。请不要在webapp类路径中包含servlet-api.jar。问题是否来自错误消息的第二行中所表达的内容？如果是，请如何修理<代码>信息：在java.library.path上找不到允许在生产环境中实现最佳性能的基于APR的Apache Tomcat本机库：/usr/lib/jvm/jdk1.7.0/jre/lib/amd64/server:/usr/lib/jvm/jre/lib/amd64:/usr/lib/jvm/jdk1.7.0/jre/。/lib/amd64:/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/server:/usr/lib/jre/jre/jre/jvm/jre/jvm/jvm/jvm/amd64:/usr/lib，我在路径中包含了servlet-api.jar，因为项目中有一些sevlet。关于库的包含，属性->Java构建路径->添加jar并将它们复制到WEB-INF/lib中吗？确保所需的库包含在部署程序集中（项目属性->部署程序集中），并且servlet api不存在。
