help needed to start java/eclipse app on F17

[M. Fioretti]

Greetings,

I am trying to start Xowa (http://sourceforge.net/projects/xowa/ ) on
a fc17, x86_64 box

when I launch it as explained in the readme file, I get the error
below, even if I have Java and eclipse-swt installed:

test #> rpm -qa | egrep -i 'java|eclipse'
eclipse-swt-4.2.1-2.fc17.x86_64
java-1.7.0-openjdk-1.7.0.9-2.3.5.fc17.x86_64
tzdata-java-2012j-1.fc17.noarch

I have alreadysearched online for those exceptions and errors, but
practically everything I have found refers to very old versions of
Fedora, and as far as I understand, not applicable to my case. I am
not sure what to do or check next. Any help is appreciated!

Marco

test #> java -Xmx256m -jar xowa_linux.jar
