Hi,

I’ve tested this both with my project and with the sample project (agile hybrid). For the agile hybrid project, when I click on ‘Release 1 Stores’, select the ‘list’ view and click on ‘print’, I get a PDF I can either download or open. Only it isn’t a valid PDF – it’s actually a 500 error page. So there seem to be two seperate bugs. Firstly, when creation of the PDF fails I shouldn’t get a PDF. Second, PDF creation should work!

This is running on Ubuntu, using jdk 1.5_0_13-b05, tested both with IE and Firefox on windows, and Firefox on Ubuntu. On IE I at least get to see the text of the 500 page rendered in the browser – obviously the mime-types are getting screwed up.

I looked at the contents of my logs for the time when I tried this and found the following stack trace in production.log:

As it turns out this issue only occurs with Java 5 but is resolved with Java 6.

If you are using Java 5 you may want to try starting up the Mingle server with the following option:

-Djava.awt.headless=true

(This can be added in the ‘MingleServer’ script around line 270)

We have java 6 on our server and this is still happening.

SUSE Linux Enterprise 10 – Linux subversion 2.6.16.27-0.9-bigsmp #1 SMP Tue Feb 13 09:35:18 UTC 2007 i686 i686 i386 GNU/Linux

Hi Brad,

If the issue you are having is indeed the same one related to the graphics library, you may want to try the setting Josh recommends above.

If you have tried that and it has not worked, or the exception you are experiencing is different, you may want to zip up a copy of your logs folder and submit a support request on our website so someone can take a look at it.

This also fixed the issue running on Mac OS X using:

java version “1.5.0_13”
Java™ 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05-237)
Java HotSpot™ Server VM (build 1.5.0_13-119, mixed mode)
