Spring MVC with tiles: java.lang.NoClassDefFoundError: org/springframework/beans/factory/NoUniqueBeanDefinitionException

Question

I am new to spring and I am following some of the online tutorial website to try my 1st web site with spring-mvc , hibernate with mySQL as back end, tiles.

I have configures some of the files and included all the neccessary jars to this project and when I try to start my Apache-tomcat-7 instance from my eclipse I am getting the below error.

I have read more than 15 threads with the same exception but since my lack of knowlendge I couldn't resolve my issue. I am struggiling since 2 days to resolve this issues.

Let me know if i need to paste any other information.

Below is my error Message:

Answer 1

You have provided the Spring classes (dependent jars) during the project compilation time, but not during the runtime.

Your Apache-tomcat-7 server NOT able to resolve and load the Spring dependencies (jar files), so you need to add the Spring jars to the Tomcat classpath.

So, copy the spring dependency jar files to the Tomcat/webapps/yourproject/WEB-INF/lib folder or directly to Tomcat/lib folder.
