Re: java.awt.AWTError: Cannot load AWT toolkit: gnu.java.awt.peer.gtk.GtkToolkit


An off the top of my head guess would be - do you have GNOME installed?
Reasoning ... GtkToolkit refers to GNOME and would be using the GNOME widgets as peers in the same manner the Motif widgets were formerly used.

Hi,
I am not so familiar with Java, and I am trying to get my brokers Java trading app working on my notebook. I am running Debian Etch with the following Java environment installed: 

$ wajig list-installed | grep java
java-common
java-gcj-compat
libhsqldb-java
libjaxp1.2-java
libjline-java
libservlet2.3-java
libxalan2-java
libxerces2-java
libxt-java
openoffice.org-java-common
sun-java5-bin
sun-java5-demo
sun-java5-fonts
sun-java5-jdk
sun-java5-jre
sun-java5-plugin

When I try to invoke the app, the following happens:
s$ java -cp jts.jar:pluginsupport.jar:jcommon-1.0.0.jar:jfreechart-1.0.0.jar:jhall .jar:other.jar:rss.jar -Xmx256M jclient.LoginFrame . Exception in thread "JTS-Main" java.awt.AWTError: Cannot load AWT toolkit: gnu.java.awt.peer.gtk.GtkToolkit

   ...14 more
It looks like maybe something isn't installed or a configuration problem, any suggestions?
I have this same Java app working on my desktop, so I know it works, but I am using older Java packages on the desktop, so I am not sure the two machines are really comparable.
