我想在我的JSF页面上显示一个PDF文件,我已经检查了这个
how to display a pdf document in jsf page in iFrame,但我不想在iframe上显示它(因为它会生成滚动条).我只想将pdf显示在像图像这样的页面上,并能够为它提供宽度和高度.
编辑你好BalusC.我仍然无法显示pdf内联.这是我的代码.
@WebServlet(name = "pdfHandler",urlPatterns = {"/pdfHandler/*"})
public class pdfHandler extends HttpServlet {
private static final int DEFAULT_BUFFER_SIZE = 10240;
protected void processRequest(HttpServletRequest request,HttpServletResponse response)
throws ServletException,IOException {
String requestedFile = request.getPathInfo();
File file = new File("/Users/KingdomHeart/Downloads/Test/pdf/" + requestedFile);
response.reset();
response.setContentType("application/pdf");
response.setBufferSize(DEFAULT_BUFFER_SIZE);
response.setHeader("Content-Length",String.valueOf(file.length()));
response.setHeader("Content-Disposition","inline; filename=\"" + file.getName() + "\"");
BufferedInputStream input = null;
BufferedOutputStream output = null;
try{
input = new BufferedInputStream(new FileInputStream(file),DEFAULT_BUFFER_SIZE);
output = new BufferedOutputStream(response.getOutputStream(),DEFAULT_BUFFER_SIZE);
byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
int length;
while((length = input.read(buffer)) > 0){
output.write(buffer,length);
}
}finally{
output.close();
input.close();
}
}
...
}
