Another Try: Struts Advanced Image/Resource Retrieval and Flash

[Micael]

This email has spaces, etc., so let's see if it has this when it arrives 
there.  If not, sorry.

Presently I load images as follows, since I want to control who has access 
to my images and other like resources.  First, an Action subclass, viz. 
ActionStaticResource, cf. infra, to retrieve and to deliver the image, 
letting me store the image inside WEB-INF and isolated from the 
outside.  Second, I access the image via an html:link html:img call in 
Struts, e.g.:

FOR CSS

<html:link 
href='staticResource.MichaelMcGradyHomeSites?content_type=text/plain&resource_source=css/index_css.css'/> 

Or:

FOR IMAGES
<html:img 
src='staticResource.MichaelMcGradyHomeSites?content_type=image/gif&resource_source=graphics/struts-power.gif' 

               alt='Powered by Struts'
               height='15'/>
(I use ".MichaelMcGradyHomeSites" instead of ".do", free ads, you 
know!)  This includes the appropriate references in the struts-config.xml to:

  <global-forwards>
    //....
    <forward name='staticResource'
             path='/staticResource.MichaelMcGradyHomeSites'/>
    //....
  </global-forwards>
And:

  <action-mappings>
    //....
    <action path='/staticResource'
            type='com.michaelmcgrady.struts.action.ActionStaticResource'
            scope='request'
            input='staticResource'>
      <forward name='staticResource'
               path='staticResource'/>
    </action>
    //....
  </action-mappings>


public final class ActionStaticResource
    extends Action {
  public ActionForward execute(ActionMapping mapping,
                               ActionForm form,
                               HttpServletRequest request,
                               HttpServletResponse response)
      throws IOException,
             ServletException {
    response.setContentType(request.getParameter(StaticResource.CONTENT_TYPE));

    try {
      String              fileName = WEB_INF.getClasspath() + 
request.getParameter(StaticResource.RESOURCE_SOURCE);
      FileInputStream     fis      = new FileInputStream(fileName);
      byte[]              imageBuf = new byte[1024];
      BufferedInputStream bis      = new BufferedInputStream(fis);
      byte[]              bytes    = new byte[bis.available()];
      OutputStream        os       = response.getOutputStream();

      bis.read(bytes);
      os.write(bytes);
    } catch(Exception e) { System.out.println(e);}
    return null;
  }
} /// ;-)
I have tried to apply this strategy to SWF (Flash) files, using hints I 
have received before.  But, I have not succeeded.  I am a slow learner, I 
guess.  I am not sure what I am doing wrong.  Does anyone have a strategy?

Thanks for any help
