The file data is written from the response, so if it appears in the file, it can be extracted, regardless of whether it is visible in the Tree View Listener or not. > However, if I set it to write the response to a file and get: > > <?xml version="1.0" encoding="UTF-8"?> > <testResults version="1.2"> > <httpSample t="5" lt="5" ts="1240861767241" s="true" lb="HTTP Request" > rc="200" rm="OK" tn="Thread Group 1-1" dt="" de="ISO-8859-1" by="34" > sc="1" ec="0" ng="1" na="1" hn="cocmcl-naeng30"> > <responseHeader class="java.lang.String">HTTP/1.1 200 OK > > Transfer-Encoding: chunked Could perhaps be the chunking that is causing the problem. > Server: Jetty(6.1.16) > > </responseHeader> > <requestHeader class="java.lang.String">Connection: keep-alive > </requestHeader> > <responseData class="java.lang.String"/> Which is an empty String, so no wonder the display shows nothing. There's no sign of the string 844fc1e22a274c7eba24daa06c3b275b which you say appears in the browser. > <responseFile class="java.lang.String"></responseFile> > <cookies class="java.lang.String"></cookies> > <method class="java.lang.String">GET</method> > <queryString class="java.lang.String"></queryString> > > <java.net.URL>http://localhost:8080/loadtest-servlet/sessionid</java.net.URL> > </httpSample> > > </testResults> > Please try using the Save Responses to a file element. It may well also create an empty file, but it is a useful check. Also, try using the HttpClient sampler in case that handles the response better.
