Hello,
I have a little problema using a Stream Result. I don't understand how
to write to an InputStream, I've seen the solution using the
StringBufferInputStream but that is deprecated and if the content is
big, it may be a memory problem.
So I have 2 questions: how to use the stream result without making a
big string first (it's not streaming), and the second, How about to
pass the action an output stream instead of an input stream?
I have made a trial with this:
class ... {
...
protected InputStream inputStream;
public InputStream getInputStream() {
return inputStream;
}
public void setInputStream(InputStream inputStream) {
this.inputStream = inputStream;
}
public String exportProjectDataAsXml(){
PipedOutputStream os = new PipedOutputStream();
PipedInputStream is = new PipedInputStream(os);
BufferedInputStream is2 = new BufferedInputStream (is);
inputStream = is2;
exportSvc.exportProject(project, os);
return "exportxml";
}
}
In the JDK docs says:
Class PipedOutputStream
...
Attempting to use both objects from a single thread is not recommended
as it may deadlock the thread.
I think I'm doing something very wrong, but how can I convert an
outputStream to an inputStream without writing a string or byte array?
It is deadlocking the tomcat thread.
Does anybody know how to make it work?
Thanks
