Thanks a lot for your immediate reply which helped me a lot to resolve this problem.
The solution *Christian Bollmeyer *provided is just fine;I make the image display properly;* **Bart Busschots's *advice is of great useful,I check all my webapp to make sure all the things go as expected.* **Wendy Bossons's * code is right in a jsp page-----------it is the same as mime.But the flash can NOT display when I put it in a Tiles file,and it is the real problem I met as Dave Newton pointed out.* *The solution to flash-problem is* *to name the movie's value you want to insert as a context-Relative url as following: <PARAM NAME=movie VALUE="${pageContext.request.contextPath }/tiles/myFlashMovie.swf"> and the code to insert a flash is to be: <object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
codebase=" http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0 " width="783" height="90" id="logo" align="middle"> <param name="allowScriptAccess" value="sameDomain" /> <param name="movie" value="${pageContext.request.contextPath}/tiles/logo.swf" /> <param name="quality" value="high" /> <param name="bgcolor" value="#ffffff" /> <embed src="${pageContext.request.contextPath}/tiles/logo.swf" quality="high" bgcolor="#ffffff" width="783" height="90" name="logo" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" /></object>
I got it as what I said.And if there is any better way ,please notice me. Thanks again.
