Problem with spark xmpp

[Maykel Franco <maykeldebian@xxxxxxxxx>]

Hi, I have install the spark client xmpp. I works very well with
openfire, but suddenly when I exec spark:

[maykel@maykel-arch ~]$ spark
Exception in thread "main" java.lang.NoClassDefFoundError:
com/install4j/runtime/Launcher
Caused by: java.lang.ClassNotFoundException: com.install4j.runtime.Launcher

Could not find the main class: com.install4j.runtime.Launcher.
Program will exit.

[maykel@maykel-arch ~]$ echo $JAVA_HOME
/usr/lib/jvm/jre1.7.0_55

[maykel@maykel-arch ~]$ java -version

Thanks in advanced.
