Calling Java.jar from Perl using System ()

Question

The name pretty much says it, I'm trying to run a java program (.jar file) to run from a Perl program. I read another post on Stackoverflow saying that this syntax is correct:

system("java filename.jar");

However, this gives me the following error. I'm not sure the problem is that it shows the file name as "filename / jar" instead of "filename.jar"

Exception in thread "main" java.lang.NoClassDefFoundError: filename/jar
Caused by: java.lang.ClassNotFoundException: filename.jar
