Hi David,

If you believe or not, I have tried to find a solution with google. Your hint with the system property java.awt.headless and some changes in the code helped. Thank you very much.

Regards Manfred

Hi,

there is a simple solution: set the java.awt.headless system property to true. More or less every class in awt need a window server which is not available on all systems if no user is logged in.

did you ever heard about this ominous thing called 'guugle' (maybe i wrote it wrong), its supposed to be able to -search- a lot of public HTML pages for text and some people use it to type 'Can't connect to window server - not enough permissions' in and find a solution for your problem. I tried and the sixth search result had a solution for your problem...

regards, David

Hello,

Our wo-application offers the possibility to generate simple PDF reports. For this purpose we use jasperreports and few classes from the awt-packages like Dimensions and FontMetrics. Everything works fine when started from XCode. The generation of PDF works also in deployment if a user is logged in, but when no user is logged in and the login window of mac os x is shown on the deployment machine then the exception as copied below is thrown.

It seems there is a problem in the usage of the awt-classes which I need to calculate size of the used fonts and styles.

The error only occurs when no user is logged in (which is the normal situation in deployment machines).

Did someone have the same experience or an idea?
Is there a possibility to solve this issue?

Thanks for your help.

Sincerely,
Manfred
