    Now the grails issue appears to be fixed, I’m having another go at stress testing. This time when I log in with my temporary user the page appears to be empty. What does it look like from your end? Here’s the code: \\\ SingleSignOnHelper ssoHelper = new SingleSignOnHelper(); WebResponse resp = ssoHelper.signIn(webConv, url, member); System.err.println(“member dob: ” + member.getDob()); System.err.println(“member Uni ID: ” + member.getUniversityId()); System.err.println(“resp after signing in: ” + resp); System.err.println(“text after signing in: >” + resp.getText() + ”<”); WebForm form = resp.getFormWithID(“studentForm”); \\\ and here’s the output: \\\ member dob: Mon Nov 16 00:00:00 GMT 1964 member Uni ID: 3999100 resp after signing in: HttpWebResponse [url= https://test-mrm.warwick.ac.uk/mrm/index.htm ; headers= CONTENT-TYPE: text/html CONTENT-LENGTH: 0 CONNECTION: Keep-Alive SERVER: Apache/2.2.9 (Unix) mod_jk/1.2.26 mod_ssl/2.2.9 OpenSSL/0.9.7d DATE: Tue, 17 Aug 2010 12:42:27 GMT KEEP-ALIVE: timeout=5, max=95 ] text after signing in: >< Exception in thread “Thread-2” java.lang.RuntimeException: java.lang.NullPointerException \\\

    Since the URL is https://test-mrm.warwick.ac.uk/mrm/index.htm and the response includes a Content-Length header of 0 bytes, this would seem to be an issue with your application, rather than with websignon – is it possible that you always return a Content-Length of 0 and this is just responding differently to a browser?

    Better still, can you get the stack trace of the \\\ Exception in thread “Thread-2” java.lang.RuntimeException: java.lang.NullPointerException \\\ from your server logs? That might indicate where your problem lies.

    Re: page returned after signing in appears empty
    The stack trace isn’t very exciting – the null pointer exception is just caused by failure to find the form I’m expecting in the page (which I assumed was because it had no content). \\\ at uk.ac.warwick.stresstest.TestMonitor.run(TestMonitor.java:23) at java.lang.Thread.run(Thread.java:595 <>) Caused by: java.lang.NullPointerException at loadTest.ViewStudentStressTest$ViewStudent.run(ViewStudentStressTest.java:87) at uk.ac.warwick.stresstest.TestMonitor.run(TestMonitor.java:21) ... 1 more \\\

    It works fine on my dev machine so I’m guessing the app itself is OK. Do the SSO logs indicate whether login has been successful?

    Hi Zoe, In the websignon logs I can see several logins by your stress testing users, and attribute lookups from the mrm application for their details – so it seems that websignon is handing them off correctly. For some reason, these users are then being redirected to /mrm/index.html, rather than /mrm/staff/mainMenu.htm – but I don’t think this is an issue with websignon. Mat

    OK, not an SSO issue then. /mrm/index.html just redirects to /mrm/staff/mainMenu.htm so it remains a puzzle. Perhaps could be something to do with the stress testing framework. Thanks for checking.

    Re: page returned after signing in appears empty
    Thanks all for your help with this – it was indeed an error in my application. A filter was directing test users differently, so though it appeared to work in real life but not with the test user, this was actually of my own (forgotten) making.
