JavaTools Eval Version and Prerequisites

JavaTools requires the latest Java, this is currently Java 7 update 51. Please make sure you have J7U51 installed and in working order before requesting JavaTools. You can check your Java version from the command line with:

java -version

It should say something like

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b02)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)

Note the 1.7.0_51 in the output. This means Java 7 update 51.

If you want Java code compilation from JavaTools, you need the JDK (Java Development Kit), not just the JRE (Java Runtime Engine). The JRE does not have a compiler. You can use the JRE as well, but then you will not have Java code compilation as there is no Java compiler.

If you are using Windows, you need .Net 4 installed and in working order. JavaTools does not support earlier versions of .Net. If you want C# code compilation from JavaTools, you need a C# compiler, not just .Net. The same is true for F# code compilation from JavaTools: you need an F# compiler for the JavaTools F# code compilation, not just .Net.

With these prerequisites mentioned above taken care of:
