Yeah, that's what I'm saying. Install the Java .exe like you'd install any other windows exe in WINE. I'm not sure it will work, though. Like I said, running a Java virtual machine through a compatibility layer may cause problems (which is why I advise backing up your currently installed WINE apps).
I don't believe WINE has native Java support, but I could be wrong there.
I don't know what you're trying to run using Java, but one of the points of Java is to enable people to run a given Java app on any machine that has a Java virtual machine installed, regardless of the host platform.
However, for the sake of ease of installating, many Java apps come with platform-specific installers for the sake of easing the process of installing the program in a way that will allow the Virtual machine to run it. For instance, Frostwire is Java-based, but it comes in a binary executable installer for Windows, as well as source tarballs, and even has an .rpm for Fedora/Redhat/other rpm distros. (Seems to sort of defeat the purpose, but that's the way they are sometimes.)
What's the app in question? Often Java-based programs are more cross-platform geared so there might be a Linux-based installer that will allow you to skip installing via Wine.
