[jcifs] RE: jcifs Digest, Vol 17, Issue 8. Followup. NTLM, Windows Login in pops up, ehn making long request

[Frederik Heick]

Topic: NTLM, Windows Login in pops up.

Environment:
j2ee : WebLogic 8.1 sp2
jdk  : 1.4.1_05
Jcifs: 0.8.3


I have made extensive trial-and-error, and I have nailed it down to the
following problem.

My system makes measurements on some remote systems, which some times
takes quite a while. 1-5 minutes.
When a request has a long response time, then the Login box will pop up.
I have traced to it "step 2", right after this command is executed, a
"401" is in my access.log, and a Windows Login box pops up.

But the funny thing is that it is not consistent, sometimes it works
fine even if the measurement took 3 minutes, sometimes it fails at 3
minutes or less.

I then write my username,password and domainname in the login box. Then
the exact same request is made one more time.


The code :

test.jsp
	<FORM ACTION='/MawisJsp/MawisWebServlet' NAME='inputForm'
METHOD='POST'>
		<INPUT TYPE='HIDDEN' NAME='OPERATION' VALUE='COMPOSITE'>

VALUE='ExtendedMeasure'>
		<INPUT TYPE='HIDDEN' NAME='COMEFROM' VALUE='test.jsp'>

MawisWebServlet
	...{generate input object}...
		MawisAPI output=null;
		try {
			...
			MawisEngineDelegate delegate = new
MawisEngineDelegate();
			//step 1
			//this method call can take up to 5 minuts
			output =
delegate.drive(input,request.getRemoteAddr(),WebConstants.SERVLET_NAME_M
AWIS_WEB_SERVLET);
			//
	
request.getSession().setAttribute(WebConstants.WEBXML_OUT ,output);

			//
			dispatcher =
request.getRequestDispatcher(inputParameters.getFirstParameterValue(FORM
_INPUT_FORWARDTO));
			RequestDispatcher dispatcher =
request.getRequestDispatcher(inputParameters.getFirstParameterValue(FORM
_INPUT_FORWARDTO));             
			response.setContentType("text/html");           

			//step 2
			dispatcher.forward( request, response );
		} catch (MawisException e) {		    
			RequestDispatcher dispatcher =
request.getRequestDispatcher("error.jsp?"+WebConstants.LAST_MESSAGE+"="+
e.getMessage());             
			response.setContentType("text/html");           
			dispatcher.forward( request, response );

		}
