恳请大家告诉我struts下显示一张存入数据库的图片怎么做

[lee821129]

我找不到struts的例子，试着用servlet,但是因为用response，就写了个action,但是JSP页面显示时没有执行这个action。
希望大家给我一个struts的例子，修改下面的代码也行，谢谢!!!1

public class ShowImageAction extends Action {
public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws IOException {
BookService bookService = BookService.getInstance();
String bookID = request.getParameter("bookID");
BookBean book = bookService.getBook(Integer.valueOf(bookID).intValue());
byte[] b = book.getFileStream();
response.setContentType("image/jpeg");
OutputStream outs = response.getOutputStream();
outs.write(b);
outs.flush();
return null;
}
}
Jsp代码：
<h2>封面：</h2><img src="/magbookmanage/ShowImageAction?bookID=${book.bookID}"/>

唉，随口就给我加了这个功能，做不出来。
没有人会吗？只要能解决，什么方法都行啊
