Installing native java on Current, .tgz missing? 32bit.

Hello, I have been trying to install jdk 8 / zulu openjdk. The slackbuilds for regular openjdk wont compile, this has been talked about before. The zulu slackbuild is 64bit only. So I went to zulu to download the .tgz. When I extracted the file it was just a normal directory and no .tgz to install a package with. Am I missing a step? Same with Oracle's regular jdk8. It downloads as a .tar.gz and when I extract it its just a normal directory. I assume I have to do something to make it a .tgz so I can install but I am unsure what to do.
