New User : Java Error When I Try to Install

I am trying to install serviio 0.5.2 on my 24" iMac running 10.6.8 with the latest version of Java from June this year. When I try to install serviio I get an error message

Cannot launch Java application

Uncaught exception in main method:
java.lang.AbstractMethod Error:
org.apache.xerces.dom.DefferedAttrNSimpl.getTextContent()Ljava/lang/String:

The only option I get is to Quit.

Help please

I saw this only 1x before, and don't know why you're getting it. Looks like your Java has a incompatible library on the classpath, but don't know how to fix it on a Mac.

is it java 1.6 or 1.7 ??????

Not the easiest question to answer. I had to use http://javatester.org/version.html to find the answer.
It reports I am using 1.6.0_26 as supplied by Apple.
