Get Oracle Java 1.8 in windows without installing it

Question

Is it possible to get Java in zip format? I don't want to install it by getting .exe file.

Is there any zip version of Java 1.8 so that I can download it and extract it and start using it in my Windows machine (64-bit processor)?

Answer 1

You can extract the JDK folder from the Installation EXE.

Check this link for the steps. The post was for JDK 1.7 it will work for JDK 1.8 also

Do the following.

Steps

1. Download JDK from Oracle
2. Download and Install 7-zip from here
3. Open installition exe using 7-Zip
4. Extract the tools.zip
5. Extract the content of tools.zip to a folder (e.g. c:\jdk).
6. Open the extracted folder in cmd prompt.
7. Execute for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" command
8. Set JAVA_HOME to the jdk (e.g c:\jdk) folder.
9. Add %JAVA_HOME%/bin to the PATH env variable.

Testing

Run the following command to check the installation, it will print the version of JDK.

c:> javac -version
javac 1.7.0_51

NOTE: Tested with JDK 1.7 and 1.8

Answer 2

I was looking for a solution to this as well. I'm not sure why the OP wanted to do this. I'm just trying to get a newer version of java for new development while not interfering with an older Java install which a legacy application requires (I'd like to update the legacy app, but it's not an option, now)

I think the hack I am going to try is this:

1. Install 1.8
2. Take a copy of the install folder
3. Uninstall 1.8
4. Reinstall / Repair 1.7
5. restore the copy of 1.

I'm sure if I had a better understanding of what the install is doing, this would not be necessary.
