Subject: [Pljava-dev] org.postgresql.pljava.internal.ServerException running linux headless mode
Date: Tue, 31 Oct 2006 09:27:12 -0700
Message-ID: <45477960.5070604@softhome.net> (raw)

Supportive helpers,

I am running Postgresql 8.1.3 on a Linux machine and attempting to 
execute some Java code that needs to access libawt.so in headless mode.  
After looking at the page 
http://wiki.tada.se/wiki/display/pljava/Module+Configuration I do not 
seem to find a way to do this.  In reviewing the page 
http://forum.java.sun.com/thread.jspa?threadID=760969&start=105 it 
instructs me to start java with "-Djava.awt.headless=true".  I need some 
direction on how to accomplish this task.

My code has been tested and works fine on Windows running PLJava 1.2 
with postgresql 8.1.5 and Java 5 build 9.

The problem is when I attempt to run on Linux running PLJava 1.2 with 
postgresql 8.1.3 and Java 5 build 9.

It seems to revolve around attempting to run in Linux headless mode.

At the present time I am receiving the following error:
org.postgresql.pljava.internal.ServerException: 31 Oct 06 08:48:29

There are 7 more stack dumps, but this was the first and the most 
informative.

Any and all help would be appreciated.

thanks Scott
