Answer 1

Try this.

1. Right click on project name -> click on properties
2. Go to Deployment Assembly
3. Click on Add -> Java Build Path Entries -> Next
4. Select Maven Dependencies -> Finish -> Apply -> OK
5. Clean project and server. Restart the server
6. Check console. ContextLoaderListener exception should not be generated now.

Answer 2

It shows that you have missed some jar files. I guess one of the spring jar files is not packed with your war file, or maybe it does not exist in your destination application server, Are you deploying your application war file manually? BTW which version of Spring you are using?

Answer 3

You are missing org.springframework.web.context.ContextLoaderListener, located in spring-web-VERSION.jar, from your runtime classpath. It doesn't help if they're on your build path if they cannot be found runtime. You need to package the .jars with your .war libs for them to be found.

Answer 4

You are missig one of the following thing while configure your application

• Missing Jars

  Download latest Spring MVC 3.2.5 RELEASE jars from here

• Add Jar files to Build Path

  Add your downloaded jar file into project Build path . Read this article link1 and link2 .

hope this will solve your problem.
