I want to install Java 7 Server SE JRE on a Windows server box. Reading through the instructions here:

http://docs.oracle.com/javase/7/docs/webnotes/install/windows/server-jre-installation-windows.html

It says to: The Server JRE files are installed in a directory called jdk1.7.0_ in the current directory.

However, there's a lot of stuff in that tar file. I just want to use the jre folder right under jdk1.7.0_.

Can I just copy over /jdk1.7.0_/jre and it's subfolders? Are there any downstream impacts I should be aware of, in terms of security and performance? Or any other issues besides the loss of functionality?

Ultimately, I want to point Tomcat to jre/bin/server/jvm.dll.

Thanks!

The "Server JRE" tarball (I'm referring to this download) file is a complete JDK/JRE bundle, and as such, should go to its own directory. The tar file contains the top level directory, so if you simply unpack the file, you'll have a fully functional JDK/JRE.

So you shouldn't copy the contents to an existing JRE or JDK directory. Just unpack the file, and you're good to go.

    Thanks for the response. It sounds like you're saying that "Server JRE" tarball has more than what's needed to just run a server on. So I just took the JRE folder and it seems to be running fine right now. Thanks. Commented Aug 22, 2013 at 0:30
