Problem : You are getting java.lang.ClassNotFoundException : org.Springframework.Web.
Context.ContextLoaderListener inward your Spring-based Java Web application.
Cause : This fault comes when y'all are using Spring MVC framework inward your Java Web application together with configured org.springframework.web.context.ContextLoaderListener every bit a listener inward your deployment descriptor likewise known every bit web.xml, but the JAR which contains this cast is non available inward spider web application's CLASSPATH. This is a real of import cast inward Spring MVC framework, every bit it is used to charge your jump configuration files e.g. applicatoin-Context.xml together with others, defined inward the context-param chemical ingredient of web.xml of your Java jump spider web application, every bit shown below :
Approach : Like whatever other ClassNotFoundException error, y'all root demand to honour out the JAR file on which this cast is bundled together with and thus add together that JAR into appropriate place, e.g. WEB-INF/lib folder of your spider web application. So that the spider web application cast loader e.g. org.apache.catalina.loader.WebappClassLoader tin run into this JAR file. You tin run into inward below stack delineate that it's the WebappClassLoader which failed to charge this cast :
Solution : It appears that the jump context loader listener cast i.e. org.springframework.web.context.ContextLoaderListener is moved to spring-web.jar since Spring 3.0. which agency y'all should create next to fix java.lang.ClassNotFoundException : org.Springframework.Web.Context.ContextLoaderListener fault :
1. If y'all are using Spring version 3.0 together with thus add together spring-web.jar into CLASSPATH i.e. precisely seat it within WEB-INF/lib folder.
2. If y'all are running inward Spring 2.0 or lower version together with thus precisely add together spring.jar into your application's CLASSPATH, same precisely seat it within WEB-INF/lib directory.
3. If spring.jar or spring-web.jar is already inward CLASSPATH together with thus your work is non due to JAR but due to wrongly configured classpath. See my post service how to bargain alongside ClassNotFoundException to troubleshoot further.
4. If y'all are using Maven the add together next dependency inward your pom.xml file :
5. If y'all are getting java.lang.ClassNotFoundException : org.Springframework.Web.Context.ContextLoaderListener error In Eclipse together with Tomcat, together with thus y'all tin likewise endeavour next steps to brand certain maven dependencies are inward CLASSPATH together with visible to Tomcat's spider web application cast loader. All y'all demand to create is add together maven dependencies into your eclipse project's spider web deployment assembly.
6. If you are getting java.lang.ClassNotFoundException : org.Springframework.Web.Context.ContextLoaderListener error in previously working projection together with y'all are certain that y'all non done anything which causes this fault together with thus y'all tin try "Clean Tomcat Work Directory" or only "Clean..". This is supposed to discard all published acre together with republish from scratch.

That's all virtually how to solve java.lang.ClassNotFoundException : org.Springframework.Web.Context.ContextLoaderListener error in Spring based Java spider web application. Mostly it's the illustration of missing the spring-web.jar file every bit hardly anyone is running alongside jump 2.0 now, but it's skillful to shout out upward that y'all demand to add together spring.jar into the cast path for older jump version together with spring-web.jar for newer jump version, starting from Spring 3.0.
