There is already a very good testing framework for Java called JUnit. There's also a very good logging framework for Java called Log4J (which Log4Perl is based upon). My suggestion is to use Perl to exec the Java testing application, let the Java testing application run to completion and then parse the results using the already existing Perl script(s) you have for QA testing. You'll have to tweak the Log4J properties file the Java application will use to fit the Perl script(s) parsing the output -or- write new methods in Perl to parse the Java testing output. No need to get fancy - you're just looking to fit the Java QA results into the framework you already have :-)
