java - How do I use getOutputStream() and getWriter() in the same servlet request? -
how use getoutputstream() , getwriter() in same servlet request?
you can't use them both @ same time. if first did getoutputstream()
can't consequently in same request getwriter()
, vice versa. can wrap servletouptputstream
in printwriter
same kind of writer have getwriter()
.
servletoutputstream out = response.getoutputstream(); // notice encoding here, important matches of // response.setcharacterencoding(); printwriter writer = new printwriter(new outputstreamwriter(out, "utf-8"));
another solution not using getwriter()
use printstream
similar, don't have type compatibility writer
or printwriter
.
// encoding again important match of output. printstream print = new printstream(os, true, "utf-8");
