我在Eclipse中尝试基本的Spring项目，当我启动tomcat时出现以下错误。

我知道这是因为JAR冲突，我尝试删除其中大部分但无法解决它。任何人都可以帮我解决它。
我正在使用Spring 2.5和Servlet 2.4。当前在项目类路径中的jar如下：
<classpathentry kind="lib" path="war/WEB-INF/lib/commons-logging-1.2.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/junit.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/standard.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/jstl-1.2.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/spring-web-servlet.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/spring-context-2.5.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/spring-webmvc-2.5.5.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/org.springframework.beans.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/spring-2.5.jar"/>
<classpathentry kind="lib" path="war/WEB-INF/lib/org.springframework.core-2.5.5.a.jar"/>
