I have a web application using struts2 and spring 3. for configuring spring I have added needed libraries in the project using build path in eclipse and also in tomcat. I added the listener in web.xml also, but when I want to run the application this error appears: SEVERE: Error configuring application listener of class org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException: org.springframework.web.context.ContextLoaderListener I googled too much but nothing happen.. some one told me to be sure to add spring-web.jar in both application lib and tomacat, but nothing chang.. please help

I often get this problem org.springframework.web.context.ContextLoaderListener java.lang.ClassNotFoundException
when eclipse does not correct puplish the application to the tomcat server (this happens often when I start eclipse the first time in a day or after some larger svn checkout)
I my case it helps to perform an sequence of action (and always wait with the next step until the step before is complete finished!!)
I would suggest using maven instead of manually fiddling around the eclipse classpath, if you have liberty to do so. Here are the simple steps that you can follow:
mvn archetype:generate -DgroupId=com.test -DartifactId=test -DarchetypeArtifactId=maven-archetype-webapp -DinteractiveMode=false
This will generate required maven project structure. Then edit the pom.xml file as below.

Build the project:
mvn clean package
And generate eclipse configuration source files:
mvn eclipse:eclipse -DdownloadSources=true
This steps are sufficient to create project structure which has required libraries in classpath with sources attached.
Finally you can import the project in Eclipse.
File > Import > General > Existing project into Workspace > Select the project directory
You can download and install maven from http://maven.apache.org/download.cgi
我看到您使用eclipse wtp插件运行Web应用程序,然后您可以在文件系统中找到扩展Web应用程序,并检查lib目录中是否装有spring.jar,您也可以看到此我的应用程序没有看到ContextLoaderListener
