How to open JNLP files.Ā A few days ago, the boss asked him to analyze some files with the help of a specific program previously loaded into the computer.Ā USB storage.Ā However, after connecting the device to a PC, you notice that the format is associated with applications Kuomintang, which you’ve never seen before expansion, and therefore can not manage.
In order to avoid convening a good meeting and complete the work assigned to him as soon as possible, he immediately opened upĀ GoogleĀ to find information aboutĀ how to open a JNLP fileĀ to the end of this guide.Ā Well, I want to tell you right away, you have come to the right place, this couldn’t be better!Ā However, before proceeding, let me provide you with more information on this topic.Ā JNLP extension identifies a specific type of file, which is designed to start the software with the following language:Ā the Java’s, its code is inĀ the network.
This type of application program is nothing more than downloading the code of the program to be executed to the PC, starting immediately after executing the first valid instruction.Ā In other words, the JNLP file is nothing more than the “launcher” of the So Java program.Ā To start it correctly, you must first install the Java environment on your work PC.Ā In the next few lines, I will describe how to do this in Windows and macOS.Ā I promise to follow the instructions I will provide you.
How to open JNLP files in Windows
As I have already mentioned in the introductory line of this tutorial, the fileĀ KMT are using the “Launcher” Web applications written in the languageĀ Java.Ā They contain information about the Internet address where the executable file of the real program is located, and the initial class to be called (that is, the first useful “instruction” to start the execution flow of the Java application).Ā problem)
In other words, the JNLP file is nothing more than the launcher of programs written in Java, and it resides somewhere on the Internet.Ā Therefore, to open such files (and the programs associated with them) correctly, you must install the Java environment on your PC in advance.
Java installation
If you have Windows and want to open the fileĀ KuomintangĀ but you did not complete Java installation, you canĀ run coverage as follows: first, to connect to the Java Web site, press the buttonĀ to accept and continue to comply with regulations on Cookies.Ā Then click the buttonĀ Java free downloadĀ to access the software installation page.
In this case, click the buttonĀ to accept and start downloading freeĀ Download the installation file (for exampleĀ JavaSEuXXXX.Ā EXE fileĀ ).Ā Once downloaded, start the program mentioned, and then press the buttonĀ toĀ immediately start the Java environment setup process.
Then click on the buttonĀ to installĀ your wish to proceed, if the announcement about the Oracle Java SE road map appears, press the buttonĀ to acceptĀ confirm that you have read.Ā From now on, the installation of the Java environment should be completed automatically.Ā You can view the progress in the following waysĀ green barĀ attached to the window displayed on the screen.Ā Finally, press the Open button in the warning window related to the completion of the installation.
It is said that the game is now complete: the PC on the PCĀ JNLP file you want to start and double-click it, just start other programs, like after a few seconds, if all goes well, you should see aĀ security noticeĀ and file Implementation related.
If the file is not open, you can right-click its icon and select the item.Ā Openā¦>Other/Other ApplicationsĀ From the suggested menu: When entering the selection panel, select the applicationĀ Java(TM) Web LauncherĀ from the list of available programs.
After ensuring that the author of the post is trustworthy, click the RUN button to confirm whether you need to open the relevant program and wait for the corresponding Java application to open.Ā That’s it!
Note: Please note that the JNLP file, because Java applications on the Internet may containĀ surprisesĀ like a virusĀ malware, and so on.Ā Therefore, to avoid accidental damage to your dataĀ or PC, be sure toĀ start only you know where they came from files.
If there’s a problem
Wait, are you telling me you failed youĀ open the fileĀ KMTĀ recommendations above techniques, even if you follow all instructions provided, it may need to “re-association” JNLP extensions to the Java execution, in order to communicate with Java.Ā The OSĀ opens the application of the relevant file type.
How simple: First, right-click the problem JNLP file, and then click theĀ PropertiesĀ appended to the recommendation of the context menu, open the tabĀ GeneralĀ and press the buttonĀ to change. This section opens withĀ .
At this point, click on the item.Ā Other applications … they-Ā search for other applications on this PCĀ is then displayed on the screen using the “File Explorer” / “Windows Explorer” panel, go to the file folder that contains the followingĀ Java executable fileĀ (in most In case,Ā C: program file (x86)Ā Java jrexxx_yyyĀ boxĀ oĀ C: program file (x86) Java jrexxx_yyy bin ).Ā Then select the file thatĀ executes the programĀ double-click.Ā Finally, in the file’s properties screen, press the accept button, and then try to double-click to execute it again: guaranteed result!
How to open JNLP files on Mac
One of the strengths of programs written in Java is their cross-platform nature.Ā In fact, these types of applications can run on any operating system previously installed in the Java environment.Ā Thus, as Windows can see, the first thing to do isĀ to open JNLP files on macOSĀ will continue to install the entire Java system.
What’s wrong is very simple: again, you must first connect to the Java download page.Ā Then click the buttonĀ to accept and continue to agree to use the cookie.Ā After clicking the buttonĀ Java free downloadĀ and press the button to repeat the operationĀ accept and start your free downloadĀ attached to the following screen.
Once you get the installation file (egĀ JRE-xxx-macosx-x64.dmgĀ ), please run it without hesitation, and then double-click the package icon in the window that appears on the screen to start the Java environment installation process.

If there’s a problem opening JNLP filesĀ
If you try to open the JNLP file according to the above instructions, absolutely nothing happens.Ā You may need toĀ restore the association of this type of file, thus indicating to Caozuoxitong for opening their correct procedures (in this case, the Java launcher).

When finished, click the buttonĀ plusĀ for all JNLP files that start with the same application, press the buttonĀ to editĀ all …… they-Ā follow.
Problems and errors
After trying toĀ open a JNLP fileĀ if you are experiencing a disturbing error message?Ā Therefore, the problem may be due toĀ the digital signatureĀ associated with the file itself.
By default, Java application execution policies in macOS are more restrictive than those established in Windows.Ā Therefore, some applications that do not have a valid digital signature may not work properly.Ā Solving this shortcoming is relatively simple: in fact, it can be ensured that the digital signature is not controlled at all, so you can run any type of JNLP file without compromising security-related errors.
However, keep in mind that doing so may compromise system security because there are no valid signatures JNLP file which could pose a threat to the integrity of the data and the PC.
Do you still want to continue?Ā Well, no problem first, log onĀ to setĀ the Mac iconĀ gearĀ attached to the barĀ marina.Ā Select the projectĀ JavaĀ and wait for the configuration panel to open automatically.Ā If you do not happen, click the button toĀ re-open the Java Control Panel.
In this case, click the tabĀ advanced.Ā Ā Next to the item checkmark is placed aĀ non-authentication (not recommendedĀ ) corresponding to theĀ revocation of the certificate signed code check is performed.Ā Was repeated using the same element, and the portion corresponding to the operationĀ performed on the TLS certificate revocation checking.Ā Finally, remove the checkmark from the entry to enable the exclusion list to revoke verification. AndĀ press the button to make the changes effectiveĀ applicationĀ yĀ good.
Once this is done, try againĀ to open the JNLP fileĀ through the process described above of interest to you: You should not have a problem!
