HI - question also relates to Windows 10, but I suspect the issues is the same.

Basically I want to install Java, but only the Server JRE (no requirement for dev tools, browser plugins etc). I can download the package from Oracle, here, but as they say, it doesn't include an installer. The installation instructions simply say "Unpack the tarball to a folder of your choice". All very well, but there must be more to it than that? How do applications that require Java know it's there?

thanks...

I haven't tried it. There's probably an installer exe in the folder that you extract the tar file to.

Hi - no, there isn't. The Server JRE is specifically without an installer.

Once you unpack it, it can be installed immediately.

It says that it's simultaneously uncompressed and extracted in one step.

Yes, I have uncompressed and extracted it - my question is HOW do I now install it?

Yes, but.... unless I am mistaken, that is a full install, including (specifically) browser plugins. The reason I went for the download I did is because, as it says on the page I linked to,

"Server JRE

A new Server JRE package, with tools commonly required for server deployments but without the Java plug-in, auto-update or installer found in the regular JRE package, is available starting from this release. The Server JRE is specifically targeted for deploying Java in server environments... "

This is for server environments, Steve.

Install instructions link included.

Blimey - sorry, but does anyone read the question? I know this - it's where I got the package from ,and if you follow the links from that to installation instructions, at the bottom of this page they are decidedly unhelpful. They just say unzip it to a folder of your choice. But there must be more to it than that. How are applications requiring the JRE supposed to know where I've unzipped the files to?

No need to get stroppy.

I was trying to help.

Ask on the Java forum.

Yes, sorry, I do appreciate the time people take, but it's frustrating because all I'm getting is "download and install it" and if it was really that simple I wouldn't need to ask the question. I have provided links and explained why it isn't that simple (to me, anyway) - maybe I'm just dumb. Anyway, I apologise again - I really don't want to be rude.

You have set JAVA_HOME variable in your path. Right click my computer > Properties > Advanced System Settings > Environment Variables. In system variables click new then fill in the variable name which will be JAVA_HOME and then put the path to where you extracted it as the variable value.

 

That will make Java available for any apps you want to run. I install it on my servers so I can use ElasticSearch for website search.

 

There is no installer for the Java JDE/JDK.

Thank you! Funnily enough, ElasticSearch is exactly what I'm looking at....
