How do I limit Java Web Start to Java 6 without Java 7 support


HOME » Java

We have a legacy medical application which gets deployed using Java
web start however, when user attempts run the application on Internet
Explorer it installs Java 7. The application does not support Java 7.
So, I have attempted to force the application to use Java 6 Update 30
but have encountered several problems with install Java using the Java
ActiveX plugin and Internet Explorer 6. Consistently, it just did not
work. The page would assume Java was installed because a plugin
developed Microsoft would confuse it.


So, attempt 2.
Bypass the plugin and redirect the user to the Java download website,
http://java.sun.com/webapps/getjava/BrowserRedirect?host=java.com&am

I have an applet which is launched by java web start launcher and
it's signed too.
I need to do some file operation on the client

I am having some issues with accessing files using JWS (Java Web
Start). The program adds a new label and image. The program runs
fine on my local computer but gives me pages of errors when I run the
program on my remote server using JWS. Here's a sample of the
error:

This occurs even after m

As, it is easy to download jars and other artifacts using />http://code.google.com/p/jnlpdownloader/


So, I am trying
to execute my business application from a small launcher
application(this launcher application is running as Java web start
application).


This launcher application,


first
download executable business application jar from URL(available at
runtime only)
And then execute the executable business jar. />

But, the following code doesn't seems to work, nor, it is
throwing any exceptions


String[] command = {"java
-jar", "JarFromURL.jar"};
Runtime r = R

I know that I can convert a Swing application to an Applet or a
Java Web Start application. Is it possible to do the same with an
application that's not Swing, say Qt using Java?


What I'm
really looking for is a UI framework using Java that's as
cross-platform as possible and also has a rich set of UI
functionality. Being able to run the application as either a desktop
or a Web application would be preferable.

Recently security vulnerabilities were discovered in the Java
Plug-In1. As a protection for the end user, Java in most browsers was
disabled promptly. What do the 'Java disabled' warnings look like?


Does the blocking of applets also affect Java Web Start
apps. (they are launched from a link in a web page) aimed at desktop
use?
