Java Runtime Environment For Web Start Applications Mac Yosemite

| Posted on by

After upgrading to yosemite, java 6 jdk is no longer available, remember that jdk 6 for mac osx is a 32-bit application, older eclipse releases needs a 32-bit jvm in order to run properly, a 32-bit application cannot run with a 64-bit jvm like java 7 or 8, so you need to install jdk 6 to run those java applications that needs a 32 bit virtual machine. The Java Runtime Environment (JRE) provides the libraries, the Java Virtual Machine, and other components to run applets and applications written in the Java programming language.


Java Web Start Technology

Java Web Start is a helper application that gets associated witha Web browser. When a user clicks on a link that points to aspecial launch file (JNLP file), it causes the browser to launchJava Web Start, which then automatically downloads, caches, andprompts the user to run the given Java Technology-based application. Prompting for future launches of the application can be turned off by the user.

From a technology standpoint, Java Web Start has a number of keybenefits that make it an attractive platform to use for deployingapplications:

  • Java Web Start is built exclusively to launch applicationswritten to the Java(TM) Platform Standard Edition. Thus, a singleapplication can be made available on a Web server and then deployedon a wide variety of platforms, including Windows 98/NT/2000/ME/XP,Linux, and the SolarisOperating Environment. The Java platform has proven to be a veryrobust, productive, and expressive development platform, leading toa significant cost savings due to minimized development and testingcosts.
  • Java Web Start supports multiple revisions of the JavaPlatform Standard Edition. Thus, an application can request aparticular version of the platform it requires, such as JavaSE 1.5.0. Several applicationscan run at the same time on different platform revisions withoutcausing conflicts, and Java Web Start can automatically downloadand install a revision of the platform if an application requests aversion that is not installed on the client system.
  • Java Web Start allows applications to be launched independentlyof a Web browser. This can be used for off-line operation of anapplication, where launching through the browser is ofteninconvenient or impossible. The application can also be launchedthrough desktop shortcuts, making launching the Web-deployedapplication similar to launching a native application.
  • Java Web Start takes advantage of the inherent security of theJava Platform. Sandbox applications are run in a protectiveenvironment with restricted access to local disk andnetwork resources. Users must also agree to run the application the first time it is launched.
  • Applications launched with Java Web Start are cached locally.Thus, an already-downloaded application is launched on par with atraditionally installed application.

The technology underlying Java Web Start is the Java Network Launching Protocol& API (JNLP). This technology was developed via the JavaCommunity Process (JCP). Java Web Start is the referenceimplementation (RI) for the JNLP specification. The JNLP technologydefines, among other things, a standard file format that describeshow to launch an application called a JNLP file.

Security

Java Web Start is built on top of the Java SE platform, whichprovides a comprehensive security architecture. Applicationslaunched with Java Web Start, by default, run without permissions in a restrictedenvironment ('sandbox') with limited access to files and network. Users are also shown a security warning and prompted for permission to run these applications.Thus, launching applications using Java Web Start maintains systemsecurity and integrity.

An application can request unrestricted access to your system.Java Web Start will display a Security Warningdialog when the application is launched for the first time. Thesecurity warning shows information about the publisher of the application, the location from which the application is accessed, and the level of access requested. If you agree to the risk, thenthe application will be launched. The information about the originof the application is based on digital code signing.

Where to find Java WebStart

Java Web Start is included in the Java Runtime Environmentavailable at http://java.sun.com.The JNLP specification can be found at JSR 56: Java Network LaunchingProtocol and API.

Using Java Web StartSoftware

Java Web Start allows you to launch Java-technology-basedapplications directly from the Web. An application can be launchedin three different ways:

  • From a Web browser by clicking on a link.
  • From desktop icons or the Start Menu.
  • From the Java Cache Viewer

Regardless of which way is used, Java Web Start will connectback to the Web server each time an application is launched tocheck whether an updated version of the application isavailable.

Launching from a Web browser

Point your web browser to a page with a link to a jnlpapplication, and click on that link.

Start

A security dialogwill pop up with information about the origin of the applicationbased on who digitally signed the code, and the level of access requested. The application will runonly if you decide to trust the vendor.

That is really all there is to using Java Web Start, but howdoes it work? The HTML links that launch the applications are, infact, standard HTML links. However, instead of pointing to anotherWeb page, they link to a special configuration file called a JNLPfile. The Web browser examines the file extension and/or the MIMEtype of the file, and sees that it belongs to Java Web Start. Itthen launches Java Web Start with the downloaded JNLP file as anargument. Java Web Start proceeds with downloading, caching, andrunning the application as directed by the JNLP file.

Launching from desktop icons and the Start Menu (MicrosoftWindows and Solaris, Linux, and Mac OS X running GNOME 2.0+)

Java Web Start technology can automatically create shortcuts foryour application on the desktop and in the Start Menu forWeb-deployed applications developed with Java technology. You canuse the Java Control Panel to control the shortcut settings.Shortcuts can also be added by using the Java Web Start CacheViewer, using the install shortcut menu item.

Using Java Web Start Software Behind a ProxyServer/Firewall

Java Web Start software must be configured with the correctproxy settings in order to launch applications from outside yourfirewall. Java Web Start software will automatically try to detectthe proxy settings from the default browser on your system(Internet Explorer or Netscapebrowsers on Microsoft Windows, and Netscape browsers on the SolarisOperating Environment and Linux). Java Web Start technologysupports most web proxy auto-configuration scripts. It can detectproxy settings in almost all environments.

You can also use the Java Web Start Control Panel to view oredit the proxy configuration. Refer to the Java Control Panel for more details.

Requirements

Desktop/Client requirements:

The client machine requires support for the Java RuntimeEnvironment (JRE), version 1.3 or later. Java Web Start isavailable for Windows 98/NT/2000/ME/XP, the Solaris OperatingEnvironment, and Linux.

Server requirements:

Applications can be deployed from any standard Web server. Inorder to use Java Web Start, the Web server must be configured withsupport for a new MIME type. See Setting Upthe Web Site.

I'm pretty sure my problem is about the same. Basically I cant install the Java 7 update cause I get an error message during download telling me I dont have mac os x 10.7 or higher....but I do. The Oracle Java update for Lion just isnt recognizing it! I have mac os x lion 10.7.5 on my laptop and for some reason, certain Pogo games wont load...it says its loading but never does and just closes. I went to the help page, did what it said, I scanned for current updates, installed them, rebooted then went back to Pogo and clicked on the java test link to see what version im running. I got the error 'missing plug in' so I clicked on it and was taken to Java's website for instructions, clicked 'Download Java for Mac OS X,' then hit sytem requirements and saw that I had to be running os x 10.7.3 or above and I have 10.7.5. I was good to go, hit download and now Im here! Annoyed and confused beause updates and upgrades are pretty basic and simple. You either meet the system requirements or you dont. I meet them but cant get them cause it says I dont....its a viscious cycle and Im rambling like a madwoman! Is there an easy yes or no answer to this, maybe a follow steps 1,2,3 A,B,C you can post for non computer savvy moms? LOL I just want the handful of Pogo games I used to be able to play, to play again...nothing complicated! And why is it only some games and not all of them? Dont answer that, my hair already hurts...haha


Im not much of a computer person, but Im sure thats more than obvious, so my apologies if my problem has nothing to do with this one....tell me where to go or what forum to read thru for help. I also want to pologize in advance for the help Im gonna need after I get this updated! lol I hear the update has something screwy with the plugins being enabled and that its another nightmare with this whole new oracle java deal. Hmmm, maybe I shouldnt even do this java update. 😕 ðŸ˜x81
