Looking for example in the jre/lib folder we see that, for each. The result of the execution of the script is shown in the following figure:Īs a last step we verify the presence of the. pack files present in subfolders and extracts for each of them the corresponding. In this case I had unzipped the folder to the path C:\Users\MolinariD\jdk-7u67 so now I enter this path as input of the script:Īt this point, the script searchs for of all the.
Once launched, as expected, we are asked to indicate the path where the folder is located in the jdk:
Now that we have created the script we just have to run it. SET fullCommand=%commandPath%%commandName% %2 %outputName%Įcho ERROR in extraction of file: %outputName% SET /P commandPath=Insert the jdk folder path:įORFILES /p %commandPath% /s /m *.pack /c "cmd /c call "%~f0" /processFile :EOF REM Author: Molinari Davis - REM Version: 0.1 jar that we can get with a replace instruction (outputName=%outputName:pack=jar%) pack file and its equivalent with the replacement of the extension in. C is the command to execute on the files, which must be enclosed in double quotes ”įor point 3) we simply invoke the command unpack200 providing as parameters the name of the. M allows you to define a search filter in order to filter the files according to a particular pattern S indicates to search recursively also on subdirectories P specifies the path from which to start the search FORFILES offers the following options we’re going to use: pack files present in subdirectoriesģ) run the unpack200 command on all these filesįor point 1) we use the SET command with the /P option that allows us to get a value inserted as input by the user, showing him a prompt message.įor point 2) we use the FORFILES command that allows us to select a group of files and execute a specific command on them. To do this, however, we don’t want to repeat manually the unpack command for each of them, but instead we write a DOS script that will do it for us (as in my case JDK needs to be installed in this way on several machines).ġ) require to the user the path of the folder containing the jdkĢ) search for all. pack files present in the jre/lib folder. The same operation performed on the file tools.pack needs to be executed for all the. We see that there is a file called “tools.pack”, so we execute the following command: unpack200 tools.pack tools.jar. Now we go into the /lib directory of the JDK and execute a dir command to get the list of available. For further details, see the official documentation of pack200 and unpack200 commands. jar files using the “inverse” command, unpack200. jar files further compressed with a tool called pack200 supplied directly with the jdk. These files are nothing more than good old. The following figure shows the contents of the folder /jre/lib where we can see some of these. pack, precisely under the folders lib and jre/lib.
#SETTING UP JDK 18 ON WINDOWS 10 ZIP FILE#
As we can see in the figure below, the content is a zip file called tools.zip.Įntering further within this zip file to see its contents we get what shown in the figure:Īt this point we extract all the contents into a folder on the file system in our user area, for example: C:\Users\MolinariD\jdk-7u67.īrowsing through the contents extracted from the zip and copied to the folder, we will find some files with extension. We open the jdk installation file, jdk-7u67-windows-圆4.exe, with 7zip and look at its contents.
#SETTING UP JDK 18 ON WINDOWS 10 INSTALL#
Trying to launch the installation we get the following error, which indicates that we don’t have sufficient privileges to install it and we must log in as administrator.īut we can’t log in as administrators, so we have to find an alternative solution.
#SETTING UP JDK 18 ON WINDOWS 10 WINDOWS 7#
In my case the operating system is Windows 7 64bit, so the version of the jdk is jdk-7u67-windows-圆4. Without these rights, in fact, you can’t install the jdk through the step-by-step wizard but it’s necessary to install it manually.įirst, after downloading the correct version of the jdk for our operating system, we try to run the installation by double clicking the icon.

In today’s post we see how to install the Java Development Kit (JDK) on a Windows machine without having administration permissions.
