Hi
You may use decorator pattern to decorate the input & output stream from
Servlet to a UnclosableInputStream & UnclosableOutputStream,
public class UnclosableInputStream extends java.io.FilterInputStream {
public UnclosableInputStream(InputStream inputStream) {
super(inputStream);
}
@Override
public void close() {
// do nothing.
}
}
InputStream inputStream = new
UnclosableInputStream(servlet.getInputStream());
inputStream.read(); // invoke the decorated ServletInputStream.
inputStream.close() // do nothing
Hope it'll helpful for you.
Zijian.
