如何使用java代码在web页面展示pdf文件呢?

实现思路:
    1.将pdf转换为流
	2.将流输出,即可实现pdf显示到页面

public void openPdf() throws IOException{
HttpServletResponse response = ServletActionContext.getResponse();
	response.setContentType("application/pdf");
FileInputStream in = new FileInputStream(new File(“d:/test.pdf”));
OutputStream out = response.getOutputStream();
byte[] b = new byte[512];
while ((in.read(b))!=-1) {
	out.write(b);
}
	out.flush();
	in.close();
	out.close();
}



html代码
 function openPdf(){
     window.open(url, "_blank","top=200,left=200,height=600,width=800,status=yes,toolbar=1,
                 menubar=no,location=no,scrollbars=yes");
}
