RE: [Wrapper-user] Headless RedHat 9.0 not liking wrapper

[Marc W. <ma...@da...>]

John,

 

The problem is the java application you are trying to run with the
wrapper (org.tanukisoftware.wrapper.test.Main) uses an awt Frame as it
is designed to allow you to simulate different events that might happen
to an application -
http://wrapper.tanukisoftware.org/doc/english/example.html#testwrapper-c
onsole - which will not work in a headless environment

 

I couldn't find a good console app example but you should be able to
whip up a simple looping Hello World app to test the wrapper on your
box.

 

Cheers

-M

Subject: [Wrapper-user] Headless RedHat 9.0 not liking wrapper

 

Hello;

 

While trying to get wrapper working on RedHat 9.0, I can't get it to
work on my headless boxes.  After searching the archives, I added the
following line to my wrapper.conf:

 

wrapper.java.additional.1=-Djava.awt.headless=true

 

However, I still get the error below.  Any help would be appreciated!
