Обсуждение: Headless Exception
Hi All ,
I have a process working with a server 8.2 which runs without a GUI.
I am doing porting to 8.3 , on CentOS 5.0 ,
The server compiled fine, and installed + running.
USING JDBC:postgresql-8.3-604.jdbc4.jar and tried
postgresql-8.3-604.jdbc3.jar too.
When i start my process , i am getting the following Exception:
java.awt.HeadlessException

The process is compiled and running with Java 1.6 , and i tried
assigning -Djava.awt.headless=true and false , and it doesn't help -
naturally since that jscan needs X.
Is there a way to bypass the X need? and use the driver with no X ?
The process is working fine with postgresql-8.2-506.jdbc3.jar - but i
am guessing it will show starnge errors in time (since the server is
8.3).
Any help would be appreciated.

UPDATE: Downloaded source for jdbc3 for 8.3 and built it. The jar product contains no reference to jscan packages and it works beutifully , might you using J2EE as default JDK for all builds ?

No, jscan is part of some anti-virus/security product on your machine. There's nothing we can do about that. Kris Jurka

JScan is in the jdbc jar ! When i built the driver myself i don't have jscan packages! Are you saying it shouldn't be there ?

It should not be there, and in fact those classes are not there in the jars available from jdbc.postgresql.org. Probably you have (arguably, buggy) antivirus software that is modifying the jar when you download it, adding those classes and breaking things! Some googling lead me to this: http://esupport.trendmicro.com/Pages/IWSx-3x-Some-files-and-folders-are-added-to-the-Jar-files-after-passin.aspx (What a terrible "feature" ..) -O

You were right on the money, that's the anti virus on my company proxy which does this crime. Oliver-You're link was very helpful in fixing it. Thanks again.
