FileNotFound exception: header_menu_Disabled.png

[TAkos]

Dear All,

Please help me getting rid of the following exception.

SmartGwt is looking for a file

/modulename/sc/skins/Enterprise/images/ListGrid/header_menu_Disabled.png

and I can see the following exception in the server logs

00000054 filter E com.ibm.ws.webcontainer.filter.FilterInstanceWrapper service SRVE8109W: Uncaught exception thrown by filter cachingFilter: java.io.FileNotFoundException: SRVE0190E: File not found: /docspace/sc/skins/Enterprise/images/ListGrid/header_menu_Disabled.png

The code of the CacheFilter is very simple:

       if (request instanceof HttpServletRequest) {

            long maxAge = getMaxAge();
            Date now = new Date();

            HttpServletRequest httpRequest = (HttpServletRequest) request;
            HttpServletResponse httpResponse = (HttpServletResponse) response;
            
            String requestURI = httpRequest.getRequestURI();
            if (!requestURI.contains(".nocache.")) {
                httpResponse.setHeader(HttpResponseHeader.CACHE_CONTROL, "maxAge=" + maxAge + ", private");
                httpResponse.setDateHeader(HttpResponseHeader.EXPIRES, now.getTime() + 1000 * ONE_DAY_IN_SECONDS);
            }
            chain.doFilter(request, response); //LINE 45 -- EXCEPTION
        }
    }

I already put a file with the requested name to the following locations. "webapp" is the web content directory (contains WEB-INF)

1) webapp\modulename\sc\skins\Enterprise\images\ListGrid\header_menu_Disabled.png
2) webapp\sc\skins\Enterprise\images\ListGrid\header_menu_Disabled.png

If I could ask the ListGrid not to look for that file, that would be even better. It started to request that file after I have migrated the application from WebSphere 6.1 to WebSphere 8.

SmartGwt version: 2.2
Gwt version: 2.1.0
Java version: 1.6

Thank you really much in advance!
