How to open a .JNLP file (Launch forms using Java Web Start) ?

Assumptions:
1. Java is already installed on your machine.
2. Your EBS form sessions are JWS enabled.

How to open a JNLP file:

1. Login to E-Business Suite.
2. Open a form.
3. It downloads frmservlet.jnlp file into your downloads folder.
4. Right-click on the file and choose Open with then click Choose another app.
5. If you see Java (TM) Web Start Launcher in this list (you may need to click More apps to expand the list), select it and check the box that says Always use this app to open .jnlp files then click the OK button.
6. If Java (TM) Web Start Launcher is not in the list, check the box that says Always use this app to open .jnlp files then click Look for another app on this PC.
    Navigate to the following location:
    C:\Program Files (x86)\Java\jreXXXX\bin
    XXXX represents a number that will vary based on the version of Java installed on the computer, for example: jre1.8.0_181.
    Select the file named javaws.exe and click Open.
7. Going forward, all .jnlp files will open using Java Web Start.
