Open jnlp file windows

Each file type on your computer is associated with an application that runs it. Files of type JNLP are run by Java Web Start. It is possible for JNLP files to become associated with another application, causing it to open incorrectly. Because Java Web Start opens the search application, when the JNLP files are associated incorrectly, the search application cannot open.

Document Details:

To modify the file association to have JNLP files open with Java Web Start on a Windows XP, Windows 7/Windows Vista, Windows 8, or Windows 10 computer, follow the steps below:

Go to the nhdeeds.com website, then click on Search County Records.

Thanks for your feedback.

I have the same problem too. However think a clarification might help here.

I would assume Java is upto date, but when you try to open a JNLP file, windows does not know which program to open it with.

Does anyone know how to set the file to open via ‘Java Web Start Program’. Afraid I have no idea how to set this in windows 10 at least, but sure someone can advise.

Adbul can you advise?

If you have installed Java Web Start, then you need to set it as the Default for JNLP files.

Try: «Start Button» > «Settings» > «System» > «Default Apps» (Scroll to the bottom of the right-hand pane) > «Choose default applications by file type» and scroll down to JNLP and set the app by clicking on the icon to reveal the options.

How to Open a JNLP File

Related

Java Network Launch Protocol (JNLP) files are used to launch applications from a hosted web server on a remote desktop client. Software such as Java Plug-in and Java Web Start programs use JNLP files to run.

Because JNLP files are program-specific, your computer may not properly recognize JNLP files to execute them using the Java Web Start application. If this happens, you need to modify your computer’s file associations so that JNLP files open correctly with the Java Web Start application.

Download and Install the Latest Version of Java

Before you edit the file association on your PC to open JNLP files correctly, confirm that you have the proper Java programs installed on your computer. Here is how:

1. On a PC, click the Windows Search field and type «Java,» or scroll through the list of alphabetized apps for the Java program. If you do not see it, Java is not installed.

On a Mac, go to Finder > Applications > Utilities Folder. You should see a Java folder. If you do not see it, you do not have Java installed.

If Java is not installed, go to the Java.com website.

Click on the Java download button. The website automatically knows which operating system you are using and directs you to the appropriate Download page.

On the Download page, click the Agree and start free download button to begin the download.

After the file is downloaded, click the install launcher and follow any instructions to complete the installation.

Editing JNLP File Associations on Windows 10

To edit the file associations on a PC running Windows 10 so that JNLP files open correctly:

1. From the Start window, navigate to the Control Panel.
2. Go to Programs >Default Programs.
3. Click Select Your Default Programs.
4. Select Choose Default Applications by File Type.
5. Choose JNLP from the list of extension types.
6. Select the option to Change program.
7. It is unlikely the proper Java application shows up automatically, so choose More apps.
8. Select Look for another app on thisPC.
9. Navigate to the Java folder, which should be located in your Program Files (x86) folder.
10. Click through the jre[version #] and bin folders to the javaws.exe application. This is the Java Web Start application launcher. Choose it by double-clicking it.
11. Confirm the choice by pressing the Close button and complete the process.

From now on, the Java Web Start application will open JNLP files whenever you click on them.

Editing the JNLP File Associations on a Mac

To change the file associations for opening a JNLP file properly on a Mac:

1. Open the Finder and locate the JNLP file you plan to open.
2. Right-click the JNLP file and select Get Info.
3. From the JNLP file information screen, click the arrow next to Open With.
4. Select Java Web Start from the list of applications in the drop-down menu. If it is not listed in the first group of options, select Other and locate it in the complete list of applications.
5. After you select the right app, click Change All to apply the change to all JNLP file types in the future.
6. Finalize the process by clicking Continue.

Now, whenever you click a JNLP file to open on your Mac, it opens automatically with the correct Java application.

Браузер не обрабатывает JNLP-файлы, а только сохраняет

Браузер не обрабатывает JNLP-файлы, а только сохраняет

Всемирная сеть сделала свои коррективы в жизнь обычных людей. Во многом это стало возможным благодаря технологии Java Script, которая сделала огромный скачок вперед. Еще каких-то 15 лет назад люди и не думали, что с помощью интернета они будут заказывать пиццу на дом или покупать билеты до Токио. Человек, который не имеет понятия, как настроить ноутбук, тем не менее управляет всеми современными благами можно через обычный браузер.

Протоколе Java Network Launching Protocol (JNLP) используется для запуска web-приложений технологии Java Web Start. Обычно обработка JS не вызывает проблем в современных браузерах, но с конкретно этим типом файлов бывает такая проблема, что браузер не открывает JNLP-файлы, а лишь предлагает их сохранить:

Чтобы исправить эту оплошность потребуется:

1. Скачать свежую версию Java

Зайдите на сайт https://www.java.com/ru/ и установите себе Java

2. Настройте безопасность Java-приложений.

После того, как вы установите Java на компьютер следует произвести настройку. Для этого зайдите в Пуск -> Все программы -> Java -> Configure Java

В настройках находим вкладку «Security». В ней будет специальное окно для сайтов, на которых разрешен запуск любых Java-приложений. Нажимаем «Edit site list» и добавляем туда сайт, который не дает запустить JNLP-файл:

Учитывайте, что при добавление сайта есть имеет значение префикс HTTP или HTTPS. После настройки — перезапустите браузер, если он был открыт.

3. Проверить ассоциацию (сопоставление) типов файлов к приложениям

Если предыдущий способ не помог, то следует проверить нужное ли приложение использует (с нужной ли программой ассоциируется) система для открытия JNLP-файлов.

Windows 98/ME/XP

«Пуск» -> «Панель управления» -> «Свойства папки» -> «Типы файлов». Ищем JNLP

Windows 7/8/10

«Пуск» -> «Панель управления» -> «Программы по умолчанию» -> «Сопоставление типов файлов или протоколов конкретным программам»

Свой вариант исправления этой ошибки пишите в комментарии.
