问题是：我应该如何修改此代码和servlet以在浏览器中显示pdf文件？
我已经尝试过ByteArrayOutputStream和response.getOutputStream但没有尝试。

The question is: How should I modify this code and the servlet to display the pdf file in the browser? I have already tried with ByteArrayOutputStream and response.getOutputStream but nothing.

推荐答案

你很幸运！书中的 iText in Action 包含一章，介绍如何完全按照您的需要做。它非常简单：在响应上设置正确的标题，然后流到servlet的输出流。

You're in luck! The book iText in Action contains a chapter that describes how to do exactly what you need. It's fairly straightforward: set the right headers on your response, and stream to the servlet's output stream.
