无法让 Java Applet 在任何浏览器中工作

Question

We are trying to download something from GE that uses Java to download when logging into the site. This is a windows 7 Professional PC. I have other computers that are able to do this successfully. Here is my order of operations:

1. Log into the site and select the file I want to download

2. Click download

3. It takes me to the page that says it will start in a few seconds but nothing happens. It is supposed to have a box that asks for Java to run.

I have reinstalled Java fresh and still nothing. Tried with multiple user accounts. Added the site to the list of exceptions in the firewalls and Java configuration. I have tried an earlier version of Java. This happens in Mozilla, Chrome and IE. I have made sure that the Java plugin shows up and is enabled. I just cant think of what I am missing. And since we are a contractor GE is not going to help us. Can anyone here think of anything?

Answer 1

Are you sure you have the Java plugin enabled? eg in Firefox, go to Settings, Plugins, and change Java Platform SE8 'Next Generation Java Plugin' to 'always activate'?

This sounds similar to the issues I had with Cisco WebVPN, Java-style. Once you have Java installed correctly and set as a plugin for any of the browsers you would like to use, see below.

Before you even start looking at browsers - if you think it is already set up correctly

1. Look at your Anti-Virus programs or anything else that could prevent it from working. McAfee Host Intrusion Protection is known to cause many Java programs to fail. Kapersky had issues, a while back, with Java on Windows ( Java Applets not loading in Windows 8 ).
2. You must have a 64-bit browser to use 64-bit Java (also mentioned in the Chrome link below).

See below for any specific things that can be modified in the browser.

Chrome 43 is the more complicated browser to set up. They have a dedicated page with instructions.

How do I use Java with the Google Chrome browser?

Firefox 38 will prompt you.

In Internet Explorer 11 , it's under Internet Options->Security . I recommend adding the hostname the applet is on as a Trusted Site (Select Trusted Sites and click the Sites button, then add the first part of the url). Click the Custom level button and make sure that Scripting of Java applets is not disabled.

If you still have problems with the applet:

1. Verify your Java version will work with the applet you are accessing
2. Verify the plugin is enabled for the browser through the Java Control Panel, which is available in Windows Control Panel, or on Mac/Linux, execute it from the JDK directory ($JAVA_HOME/ControlPanel ).

I ended up fixing the issue. I had to allow their UK site on the list for Java and enable the SSL 2.0 for HTTP in Java config as well
