Servlet: 服务器方面的产出文件包括文字和动态生成的形象
原标题:Servlet: Output file with server side include, text and dynamically created image

我有一个信封,希望能产生正常的文本和动态生成的图像。

生成的网页有一张头盔和脚 The,有一张头和脚 The。

request.getRequestDispatcher("header.jsp").include(request, response);

这样做会导致期望:

org.apache.jasper.JasperException: java.lang.IllegalStateException: getOutputStream() has already been called for this response

我能做到这一点? (主人、文本、形象、文字、脚)

最佳回答

图像不得与超文本页面相同的要求中流出。

header
text
<img src="path/to/servlet/streaming/the/image/bytes"/>
text
footer

在装上这一超文本页时,浏览器将引发第二个要求,即<代码>path/to/servlet/streaming/the/image/bytes,铺设到这条路的服务器应当利用对应产出流发送机能生成的图像。
