删除服务器上的图片
我是用ss2h做的我上传图片到服务器上,地址上传到数据库中,这是成功的,可是我删除就不行了,服务器上的图片删不了,获取不到img的值,我都找了好久了,实在没办法,还得请大神们看看
public String deleteTest(){
		testBiz.delTest(shopPoster.getId());
		String savePath = ServletActionContext.getServletContext().getRealPath(
		""); // 获取项目根路径
          savePath = savePath + "/upload/";
		File file=new File(savePath+shopPoster.getContext());
		file.delete();
		resultMap="testActionshow.action";
		return SUCCESS;
	}
jsp上的  <script type="text/javascript">
  	 function del(id){
   			location.href="shopEcsVoteOptiondeletePoster.action?shopPoster.id="+id
   		}
   	function ret(){
   			location.href="addPoster.jsp";
   		}
  </script>
   <body ><!--  
    	<form action="shopEcsVoteOptiondeletePosters.action" method="post" name="myForm">
   		--><table align="center" border="1">
   		 <s:iterator value="#request['listShopPoster']" var="listShopPoster">
   			<tr>
   				<td>
   				 <img src="Poster/<s:property value="#listShopPoster.context"/>" height="50" width="50" />
   				</td>
   				<td>
   					<input type="button" value="删除" onclick="del(<s:property value="#listShopPoster.id"/>)">
   				</td>
   			</tr>
		 </s:iterator>
		 <tr>
		 	<td>
		 		<input type="button" value="继续添加" onclick="ret()">
		 	</td>
		 </tr>
    		 </table><!--
     </form>
   --></body>

Java code
@Override
    public void init() throws ServletException {
        try {
            String tomcatPath = System.getProperty("user.dir");
            String filePath =  tomcatPath.substring(0,tomcatPath.length()-4)+"/webapps/ios/images";
            File file = new File(filePath);
            if(file.exists()&&file.isDirectory()){
                File [] files = file.listFiles();
                for(int i=0;i<files.length;i++){
                    if(files[i].isFile()){
                        files[i].delete();
                    }
                }
            }
            System.out.println("<提示:清理图片缓存成功!>");
        } catch (Exception e) {
            System.out.println("<提示:清理图片缓存失败!>");
            e.printStackTrace();
        }
        super.init();
