#java web start

[churchofthemachines]

To deploy your Java Web Start application, first compile the source code and package it as a JAR file.

Java Web Start applications are launched by using the Java Network Launch Protocol (JNLP). Hence, you must create a JNLP file to deploy your application.

The Deployment Toolkit script contains useful JavaScript functions that can be used to deploy Java Web Start applications on a web page.

If you are unfamiliar with these deployment technologies, review the Deployment In-Depth lesson before proceeding.

Here are some step-by-step instructions to package and deploy your application. The Dynamic Tree Demo application is used to illustrate the deployment of Java Web Start applications. You might want to set up build scripts to execute some of the following steps.

Click the following Launch button to launch the Dynamic Tree Demo application.

Basic Steps

1. Configure the Web server to use the Java Web Start MIME type

Configure the Web server so that all files with the .jnlp file extension are set to the application/x-java-jnlp-file MIME type.

Most Web browsers use the MIME type returned with the contents from the Web server to determine how to handle the particular content. The server must return application/x-java-jnlp-fileMIME type for JNLP files in order for Java Web Start to be invoked.

Each Web server has a specific way in which to add MIME types. For example, for the Apache Web server you must add the following line to the .mime.types configuration file:

application/x-java-jnlp-file JNLP

Check the documentation for the specifics of your Web server.

2. Create a JNLP file for the application

The easiest way to create this file is to modify an existing JNLP file to your requirements.

The syntax and format for the JNLP file is described in a later section.

3. Make the application accessible on the Web server

Ensure your application's JAR files and the JNLP file are accessible at the URLs listed in the JNLP file.

4. Create the web page that launches the application

See the next chapter, Creating the Web Page that launches the Application, for details on step 4.

Detect if Java Web Start is installed

If so, launch the application.

If not, detect if user is running IE on Window.

If so, provide link to a page that can auto-install the JRE for Windows

If not, provide a link to the general download page for the JDK/JRE.

Status

Back from the depths, where I presented and delivered two presentations over the course of two weeks and the kind of immersion I require when I do that....

SHARP:

Figured out, again, how to log on to the Mayo cloud.  Uploaded our stratified corpus.

Got Java Web Start stuff to work by modifying the Java Control Panel.

Drug NER meeting.  Had an a-ha moment where I realized I could search for a string from my mystery drugs and potentially link it to a known BN/IN using RxCUI.  See 'erirthrowhatever'.

Found the above example has two RxCuis for the exact same orthography.  This was mostly a head-scratcher.

SuCCESS:

Got 100 more cspy and 100 more path notes.

Other:

Reviewed cognitive and functional status grant.
