Installing Java manually on Windows? [duplicate]

Question

I have seen many products bundeled with JDK, I wonder if there is a way where one can install JDK by simply unzipping contents to a directory, so there is no icon created in add/remove programs, no registry entries etc.

Also in this case: How can we configure Java plugin for browsers? And how can we configure settings as seen via Control Panel entry for Java?

Answer 1

According to this, I created a batch script to build jdk archives automatically.

The essential parts of the link are:

• Create working JDK directory ("C:\JDK" in this case)
• Download latest version of JDK from oracle (for example "jdk-7u7-windows-i586.exe")
• Download and install 7-zip (or download 7-zip portable version if you are not administrator)
• With 7-zip extract all the files from "jdk-[6-7]u?-windows-i586.exe" in directory "C:\JDK"
• In command shell (cmd.exe) do the following:
  1. change directory to directory C:\JDK.rsrc\JAVA_CAB10
  2. execute command: extrac32 111
• Unpack C:\JDK.rsrc\JAVA_CAB10\tools.zip with 7-zip
• In command shell (cmd.exe) do the following:
  1. change directory to C:\JDK.rsrc\JAVA_CAB10\tools\
  2. execute command: for /r %x in (*.pack) do .\bin\unpack200 -r "%x" "%~dx%~px%~nx.jar" (this will convert all pack files into jar)
• Copy whole directory and all subdir of c:\JDK.rsrc\JAVA_CAB10\tools" where you want your JDK to be and setup manually JAVA_HOME and PATH to point to your JDK dir and its BIN subdir.

Answer 2

Yes, you can create a zipped up JDK, unzip it on the target machine and run java, javac, etc. from that directory to your heart's content.

The easiest way to create such a zip file is to install the JDK on a machine and then zip up the contents of the JDK directory. We do this in certain circumstances where we need to control exactly what configuration of Java will be used in our deployments. In that case, our scripts just point JAVA_HOME (or the equivalent) to our internally bundled JDK instead of relying on a sysadmin to install exactly what we need prior to arrival.

In terms of integrating with the browsers, that can be a bit more problematic. The short answer is no, you can't integrate directly with the browser without some sort of installer.
