How can I compile Java code in Windows without installing the whole JDK?

Question

Let’s say the runtime environment (version 1.6.0_01-b06) is already in place, but since I lack administrative privileges in this particular PC, the JDK can’t be installed. So, is there any portable JDK or standalone Java compiler for Windows that doesn’t require installation?

Answer 1

You might try taking the tools.jar file from the JDK (you would have to copy it over from another machine) and see if that worked.

javac is essentially a small exe that starts the VM with the specific class for the compiler.

Also, there is nothing (that I am aware of) about the JDK install that you couldn't do with a copy of it from another machine. So get on a machine you can install the JDK on, install it, and then copy the files to a place on the machine that you lack the rights to and it should work.

Answer 2

Eclipse works very well. being a portable ide, it will use it's own jdk. I personally use jGrasp w/ the jdk's folder as a PATH when I'm trying to write something quick.

Answer 3

You don't need to install JDK. Just copy it over from another machine, and set PATH to %jdk%/bin and JAVA_HOME to %jdk% (actually, only PATH is often enough). I do it all the time.

Answer 4

You can try Jikes.
