Thank Jesse . Meanwhile i tried something like . created a
ListenerLogDecorator class which extends LineTransformationOutputStream
and in the perform method i called it like below
ListenerLogDecorator outStream = new ListenerLogDecorator(listener);
launcher.launch().pwd(workspace).cmds(constructDefaultMatlabCommand()).stderr(outStream).join();
the decorator class contains one overridden method like below.
protected void eol(byte[] bytes, int length) throws IOException {
if(this.listener == null){
return;
}
String line = new String(bytes,0,length,Charset.defaultCharset());
this.listener.write(line.getBytes(Charset.defaultCharset()));
}
This solution is working for me but please suggest if i am on right track
