public class HessianOutput extends AbstractHessianOutput
Since HessianOutput does not depend on any classes other than in the JDK, it can be extracted independently into a smaller package.
HessianOutput is unbuffered, so any client needs to provide its own buffering.
OutputStream os = ...; // from http connection HessianOutput out = new HessianOutput(os); String value; out.startCall("hello"); // start hello call out.writeString("arg1"); // write a string argument out.completeCall(); // complete the call
