JAR can be installed on any JRE?

Hi,

as i remember the main goal of java is to create 1 apps that can be installed and run on many platforms (a particular JRE)


So, is all .jar file can be installed to any JRE? for example i install one .jar on windows, then can i expect it to work also if i install in on solaris?

Because i ve been told that the libraries on java windows are diffrent with java on other platforms.

thanks in advance.

Hi, if you use special library, for example java3d, you can need install this library for particular platform.
Same if you use in your code new features in Java6 or Java5, for example generic, you must use Java5 and above.

Yeah, assuming your jar is self contained and is pure java (no native code calls), then you can run it on any platform that has a JRE of the same or higher version that you compiled the JAR for. So, if you compile for 1.5, you can use 1.5 and above on any system (as Petr pointed out).

Thanks you guys
