http 404 from tomcat servlet in 'resources' path

Question

I am use ckeditor ckfinder in my project.but i can not find ckfinder servlet when i use the default mapping.

i can find it ,if i change the mapping path in a short path.

        <servlet>
            <servlet-name>ckeditor</servlet-name>
            <servlet-class>com.ckfinder.connector.ConnectorServlet</servlet-class>
            <init-param>
                    <param-name>XMLConfig</param-name>
                    <param-value>/WEB-INF/config.xml</param-value>
            </init-param>
            <init-param>
                    <param-name>debug</param-name>
                    <param-value>true</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
            <servlet-name>ckeditor</servlet-name>
            <url-pattern>/resources/ckeditor/ckfinder/core/connector/java/connector.java</url-pattern>
     </servlet-mapping>

when i use this that is http 404

<url-pattern>/resources/ckeditor/ckfinder/core/connector/java/connector.java</url-pattern>

when i change it to short path ,i can got it:

<url-pattern>/test/connector.java</url-pattern>

my environment is centeros6.5 tomcat7 jdk7(in windows environment i can got it in windows[window7 tomcat7])

The request is sent to

http://ip:8080/resources/ckeditor/ckfinder/core/connector/java/connector.java

Edit:

"Resources" path lead to can not find the servlet, but I don't have other set of resources related content?

I have a static directory 'Resources'

anybody kown why?
