Description - JarCheck



Check a Java jar to make sure all the javac -target versions ofthe class files are what you expect.Java application.Requires Java version 1.5 or later.All Java source code is included.to use:java -jar jarcheck.jar jartotocheck.jar 1.1 1.4where jartocheck.jar is the name of jar to check.It will check all the class files in it.In this example:1.1 is the lowest acceptable target version number.1.4 is the highest acceptable target version number.Currently, only version numbers 1.0, 1.1, 1.2, 1.3, 1.4, 1.5and 1.6 are supported. The program does not currently testminor version numbers.Why would you use this utility? To make sure that a jarintended to run under an old 1.1 JVM contains no classesaccidentally compiled with javac -target 1.5. Passing thistest does not guarantee the jar will work on an old JVM. Thejar still might use methods not bundled with old JVMs. Thisshould catch however, classes normally compiled with target1.1 that were accidentally compiled with 1.5 as a sideeffect of compiling some 1.5 class.There is a Similar program called JarLook available athttp://mindprod.com/products1.html#JARLOOK
