webpart containing flash not working

Hi ,

I have been creating one webpart that contains a flash file.The flash file has some file reference to a supporting xml file, which is done from flash file itself . 

I have used the same flash file in a normal aspx page,there I had to keep the aspx page and this supporting xml file in same folder of solution. Only then it will work.

When I am creating the webpart how can I keep the calling page and supporting file in same folder.Since the supporting file and flash file has been kept in layouts folder.

I have registered the flash to webpart code as follows.

StringBuilder sbFlashComponent=new StringBuilder();
sbFlashComponent.Append("<OBJECT classid=\"clsid:D27CDB6E-AE6D-11cf-96B8-444553540000\" ");
             sbFlashComponent.Append("codebase=\"http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0\""); 
             sbFlashComponent.Append("id =\"ThoughtLeadershipCarousel\"");
            sbFlashComponent.Append("width=\"450px\" height=\"350px\"");
            sbFlashComponent.Append(">");
            sbFlashComponent.Append("<param name=\"movie\" value=\"");
            sbFlashComponent.Append(flashUrl.ToString());
            sbFlashComponent.Append("\">");
            sbFlashComponent.Append("<param name=\"quality\" value=\"high\" />");
            sbFlashComponent.Append("<param name=\"play\" value=\"true\" />");
            sbFlashComponent.Append("<param name=\"loop\" value=\"false\" />");
            sbFlashComponent.Append("<param name=\"wmode\" value=\"opaque\" />");
            sbFlashComponent.Append("<param name=\"bgcolor\" value=\"#FFFFFF\" />");
            sbFlashComponent.Append("<param name=\"menu\" value=\"false\" />");
            sbFlashComponent.Append("<param name=\"allowScriptAccess\" value=\"sameDomain\" />");
            sbFlashComponent.Append("<param name=\"allowFullScreen\" value=\"false\" />");
            sbFlashComponent.Append("<param name=\"FlashVars\" value=\"xmlDataLinks=/_layouts/testcarousel/carousel.aspx\" />");
            sbFlashComponent.Append("<EMBED src=\"" + flashUrl.ToString() + "\"  quality=high wmode=\"transparent\" WIDTH=\"450\" HEIGHT=\"350\" TYPE=\"application/x-shockwave-flash\" PLUGINSPAGE=\"http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash\"></EMBED> ");
            sbFlashComponent.Append("</OBJECT>");

NB: The supporting xml file is not given through "FLASHVARS"
