First of all, I am a newbie to Spring security and Intellij IDEA.

I have created a starter Spring Security Project in Intellij IDEA which uses the Spring version 3.2 and security version 3.1.

I am getting the following error in web.xml.

org.springframework.web.filter.DelegatingFilterProxy' is not assignable to 'javax.servlet.Filter'

Here is my web.xml snippet.

 <filter> <filter-name>springSecurityFilterChain</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>springSecurityFilterChain</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>

Could someone please tell me what the issue is ? I searched in google and was not able to find the solution.

Finally I have solved the issue. The problem was that I had 2 versions of spring jar files in the classpath. After I deleted one version, the error vanished.
