-> Crystal Reports Author Message rajendranrForum MemberJoined: 25 Apr 2007Posts: 26 Posted: Fri Sep 12, 2008 1:11 amPost subject: response.getoutputstream() in jsp BO Crystal Report Connectivity Issue Hi all We are using Crystal Report XI R2 (11.5.8.826) and CMS is running in 6400/6401 ports. Problem Statement: We are trying to establish a connection between “BO Crystal tool” http://stackoverflow.com/questions/1776142/getoutputstream-has-already-been-called-for-this-response client with BO repository. During this connectivity, we noticed that after the first communication with Server in 6400 or 6401 port, it immediately was trying another request in 1055/1056 ports. Currently there is no service running in 1055/1056 ports, so no Clue why it’s using 1055/1056 ports rather than 6400 (which is suppose to use for connecting the repository) Can you please help us to understand why it’s using http://www.forumtopics.com/busobj/viewtopic.php?p=537918&sid=cad867cb5af725ee5e5dad09eeef8478 some random ports like 1055/1056. Also what’s the possible way to establish the connectivity even after having the proper tool version & correct port opened at both the end (Client & Server) Thanks Rajendran R Back to top ABILtdForum EnthusiastJoined: 08 Feb 2006Posts: 1646 Posted: Fri Sep 12, 2008 6:35 amPost subject: Re: BO Crystal Report Connectivity Issue From what your saying i.e. CMS on 6400 and 6401 tells me that you might be running BOXI R3 (the SIA runs on 6401). The Crystal version number is 11.5 which suggests this is XI. You have to use Crystal 2008 with BOXI R3, Crystal XI is incompatible._________________BI and Analytics Presales Consultant ------------------------------------------------------ BOXI R1, R2, R3, R3.1, CE 8, 8.5, 9, 10, Crystal Reports, JasperServer, iReport, LogiAnalytics, BIRST, Qlikview, Xcelcius, Netezza, T-SQL, PLSQL, DTS, SSIS, BODI, BODS, Kimble etc.... ------------------------------------------------------ Back to top Scott_at_PaxSenior MemberJoined: 27 Nov 2006Posts: 36 Posted: Tue Oct 21, 2008 8:04 amPost subject: Re: BO Crystal Report Connectivity Issue AndySkinner, I am running a similar environment.

Re: "OutputStream already retrieved" 843840 has already been Aug 21, 2002 3:19 PM (in response to 843840) If, before calling the getWriter() method, you wrote to the output stream, then you will get that error. If you are on a JSP doing this, referencing the reserved word "out" would give you access to the OutputStream. Like Show 0 Likes(0) Actions 2. Re: "OutputStream already retrieved" 843840 Aug 21, 2002 4:27 PM (in response to 843840) Thank you for your help. I checked my program and Ican't find any place I write something to the output stream before calling getWriter() method. Is there any other possible reasons? I have to do it in the servlet so I can't use the reserved "out". Like Show 0 Likes(0) Actions 3. Re: "OutputStream already retrieved" 843840 Aug 21, 2002 5:43 PM (in response to 843840) post your servlet code. put it in the [ code ] tags . point me to the area where the exception is occuring as well.
