APPX Desktop Client Launched via Java Web Start

Line: 113 to 113

The appx.html file exists only to provide the user with a link to click the appx.jnlp file. It is not technically needed because if someone entered the path to the jnlp file the application would launch just the same as if the jnlp file had been clicked from a link in the html file. Let's take a look at the appx.html file. This file is just a starter file that you can use to load the .jnlp file. There is a bit of javascript code that attempts to detect if a JRE is installed on the user's desktop for the Java Web Start launch. If the JRE needs to be installed or updated the script will either attempt to update the JRE or present the user with the appropriate link to download the software manually.

This is an XML file that defines the environment that the APPX Desktop Client will run it. The file is made up of elements, element values, element stanzas and comments. The file is documented with comments. Now take a look at the appx.jnlp file.

<!-- JNLP File for APPX Desktop Client 5.0.4b1 -->

Line: 2022 to 2022

If you wish to modify the Apache global TypesConfig

file and the file exists in /etc/mime.types, then you might try syntax like the following which will grep for the jnlp entry, and if not found will append an entry for jnlp support.

Changed:

<
<

[joe@webserver /]$ *grep -qs 'application/x-java-jnlp-file' /etc/mime.types || echo 'application/x-java-jnlp-file jnlp' >> /etc/mime.types*

>
>

[joe@webserver /]$ grep -qs 'application/x-java-jnlp-file' /etc/mime.types || echo 'application/x-java-jnlp-file jnlp' >> /etc/mime.types

[joe@webserver /]$
