Java Forum / GUI / June 2004JAVA GUI Portability Question
Hello, I have a summer intern writing a GUI for my code using JAVA on Linux. He tells me that anyone who wants to use the GUI must have JAVA installed on their machine. This concerns me because I know that most of the potential users of the code will not have JAVA. Is it true that even the executable will require JAVA to run? If so, is there a way around this problem? I use lots of GUIs for other programs and I don't have JAVA on my machine. Sorry for my ignorance.

The Java runtime environment can be freely distributed with the application, much like you'd distribute runtime libraries for most other languages. If you use a native compiler such as Excelsior Jet (since you mention executable files), then you probably may not need to distribute the JRE per se, but you'll need to distribute the runtime libraries for Jet instead. Essentially, there's a lot of code in the standard API, and it has to come from somewhere.  Signaturewww.designacourse.com The Easiest Way to Train Anyone... Anywhere.

It's very easy to obtain and install, and it's free. Java is one of those things that a well-equipped computer has. There are two kinds of "having Java". One means having a Java Development Kit (JDK) on your machine. This includes the basic development tools and the runtime libraries. The other means having a Java Runtime Environment (JRE) on your machine. This is just the runtime libraries without the development tools. Users only need a JRE, which is smaller.
