WebReport Studio 4.4 - Print to PDF issue.

[mmiada]

Hi all...

A user is trying to run a huge PDF report(almost 3000 pages). After 2 hours, Web browser displays an error message below.

Web browser shows:

HTTP Status 500 - java.lang.IllegalStateException: getOutputStream() has already been called for this response

Relevant part of catalina.out shows:

20:16:16,737 | ERROR | [[action]] | Servlet.service() for servlet [action] in context with path [/SASWebReportStudio] threw exception [java.lang.IllegalStateException: getOutputStream() has already been called for this response] with root cause
java.lang.IllegalStateException: getOutputStream() has already been called for this response

and...

[WRS] ERROR [tomcat-http--41] 2016-11-29 20:16:16,675 [ST-62-tDrfJpDDVGqYm1GLDfjS-cas:a03307] citation.controller.action.PrintPreviewAction - Root Cause: java.io.FileNotFoundException: /sas/sasconfig/Lev1/Web/WebAppServer/SASServer2_1/sas.wrs.tmpfiles/d20161129_1747/d2/wrsCachingStream2902554385933464974tmp (No such file or directory)

Additional info...

Navigating to sas.wrs.tmpfiles/d20161129_1747/d2 directory there are no files.

It prints out ok when few pages are selected (eg. page 1 to 50).

Session timeouts of all Middle Tier components were increased to 6 hours(360 min)

OS: RHEL 7.2
SAS 9.4
WebReport Studio 4.4

Browsers: Mozilla Firefox, Chrome and Internet Explorer, all latest versions.

Any help?

Thanks.

I'm sorry but there in no way around this issue other than printing a certain number of pages at a time. You are likely either timing out or the browser is running out of memory.
