Extract Zip File From Java

Active1 year, 4 months ago

I like to be sure that everything will work just by copying the contents of the Java folder and setting the environment variables.

Tools for Java developers creating Java EE and Web applications, including a Java IDE, tools for Java EE, JPA, JSF, Mylyn and others.
Java software for your computer, or the Java Runtime Environment, is also referred to as the Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, Java plug-in, Java plugin, Java add-on or Java download.

Step – 3 – Extract the downloaded file. Extract the download.zip file which will have the name something like, to any folder such as c:/java. You can use 7zip or Windows default unzip program. To use the windows default unzip program, right click on the zip file and select Extract All. Step – 4 – Execute java command from command line. Jun 20, 2017 If your server is a servlet container, just write an HttpServlet which does the zipping and serving the file. You can pass the output stream of the servlet response to the constructor of ZipOutputStream and the zip file will be sent as the servlet response. ZipOutputStream zos = new ZipOutputStream(response.getOutputStream).

I usually run the installer in a virtual machine, zip the java folder contents, go back to a snapshot of the virtual machine, and then unzip the compressed file.

I couldn't find a place where the latest JRE / JDK is available as a zip file...

Alternately, is it safe to assume that exe installer from sun just will just unzip the whole thing, without messing around with the registry, environment variables, etc...?

You can download a Java Portable from PortableApps.com. It will not change your system settings. You can put it on your USB stick.

UPD: for those who needs JDK there's an open-source project OpenJDK Portable

JDK is not available as a portable ZIP file, unfortunately. However, you can follow these steps:

Create working JDK directory (C:JDK in this case)
Download latest version of JDK from Oracle (for example jdk-7u7-windows-x64.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-XuXX-windows-x64.exe into the directory C:JDK
Execute the following commands in cmd.exe:
- cd C:JDK.rsrc1033JAVA_CAB10
- extrac32 111
Unpack C:JDK.rsrc1033JAVA_CAB10tools.zip with 7-zip
Execute the following commands in cmd.exe:
- cd C:JDK.rsrc1033JAVA_CAB10tools
- for /r %x in (*.pack) do .binunpack200 -r '%x' '%~dx%~px%~nx.jar' (this will convert all .pack files into .jar files)
Copy all contents of C:JDK.rsrc1033JAVA_CAB10tools where you want your JDK to be
Setup JAVA_HOME and PATH manually to point to your JDK dir and its BIN subdirectory.

Create destination folder where you can RWX (e.g. C:jdk8)
Download jdk exe from Oracle (e.g. jdk-8u72-windows-x64.exe)
Unzip the tools.zip found inside it into the destination folder
In cmd.exe, run:
- cd C:jdk8
- for /r %x in (*.pack) do .binunpack200 -r '%x' '%~dx%~px%~nx.jar'

This solution works for JDK 8 too, without Admin rights.

For JDK 8u102 things have changed, this worked for me:

Download windows JDK exe
Open with 7-Zip
Dump contents into a directory %JDK-EXE%
cmd: cd %JDK-EXE%.rsrc1033JAVA_CAB10
cmd: extrac32 111
Now have a tools.zip in directory, open it in 7-Zip
Extract contents into a new directory %JDK-VERSION%
cmd: cd %JDK-VERSION%
cmd: for /r %x in (*.pack) do .binunpack200 -r '%x' '%~dx%~px%~nx.jar'
src.zip is in %JDK-EXE%.rsrc1033JAVA_CAB9110 - put a copy into %JDK-VERSION%

Now you are ready to go.You might want to setup JAVA_HOME and PATH to point to your %JDK-VERSION% dir and its BIN subdir.

Here is a good, but a little complex, way:

Java Download And Extract Zip File

Stage 1: MSI & CAB from native installation file

Download the JRE or JDK from the Oracle (Sun) website. This method will work on any version and on SDK or JRE.
Run and wait for the installer to load. Minimize the window.
In Windows 7, you should browse to this location:
C:Users YOUR_USER_NAME AppDataLocalLowSunJava
There, you will have a few MSI and CAB files.

Stage 2: easily extract the MSI & CAB using uniextract

Browse to Universal Extractor | LegRoom.net and download UniExtract Binary Archive.
Use WinRar or any un-RAR program available to you, and extract uniextract161_noinst.rar anywhere.

Stage 3: finally, extract the inner container named core.zip

Drag & drop jdk1.6.0_31.msi or jre1.6.0_31.msi on the icon of UniExtract.exe.
Select 'Extract Method: MSI Administrative Installer'. Wait for the process to finish.
Enter the new created folder.
If you've drag-and-dropped jre1.6.0_31.msi you should have a jre1.6.0_31 folder
Follow all levels inside and you'll see core.zip.
This is what you are after. You can just unzip it anywhere and you'll have the content of the Java runtime or SDK without installing anything on your system.

* You can now close the installer of Java you've left opened in stage 1 *
