Ckfinder and Struts2

Hi,
Have somebody successfully integrated CKFinder Java version (ckfinder_java_2.0.2.1.zip) inside a Struts2 application?

I put needed files in their correct places, and add ckfinder servlet entries to the web.xml file, which now looks like this:

   <servlet>
      <servlet-name>ConnectorServlet</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>false</param-value>
      </init-param>
      <load-on-startup>1</load-on-startup>
   </servlet>
   <servlet-mapping>
      <servlet-name>ConnectorServlet</servlet-name>
      <url-pattern>
         /ckfinder/core/connector/java/connector.java
      </url-pattern>
   </servlet-mapping>
   
    <filter>
        <filter-name>struts-cleanup</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ActionContextCleanUp</filter-class>
    </filter>
    <filter>
        <filter-name>sitemesh</filter-name>
        <filter-class>com.opensymphony.module.sitemesh.filter.PageFilter</filter-class>
    </filter>
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts-cleanup</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>sitemesh</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <session-config>
        <session-timeout>90</session-timeout>
    </session-config>
    <welcome-file-list>
        <welcome-file>/index.jsp</welcome-file>        
    </welcome-file-list>
    <!-- Spring initialization -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

The file explorator is properly showed in ckfinder samples, but when I finished uploading some image, it’s not showed in the folder, and it is not uploaded. No error messages appear.

When launched demo ckfinder app indepently it works perfect.

Any hint will be greatly appreciated
