Java Applet is not running in a browser - java

I am trying to run my applet in a browser, chrome/IE but I get the following message:
Your security settings have blocked a local application from running
Due to Oracle, changing security level in java control panel from high to medium will solve the issue, but it does not. I have even tried the low level, and custom level too enabling all applications to run without any prompt. I have also changed the advanced setting to allow unsigned applets to run.
It does not work in any way.
Any help is appreciated.

Do the following
Go to IE
Tools -> Internet Options
Go to the Advanced Tab
Under Java(Sun) Select the check box saying 'Use JRE ... for applet' (requires restart)
Select Apply/Ok. Restart IE and try loading the applet again.

You can either make sure that the applet is signed by a valid cert, and it is not a self-signed cert. Or if you just want to bypass the warning, you can add the domain address to Exception Site List.
Java Control Panel -> Security tab -> Exception Site List
and also you may also try to add the website to the Trusted Zone in your IE if you are sure that the website is safe. In Trusted Zone, there are fewer restrictions to block you from running applet and running the out-of-date ActiveX.

Cannot get Java Applets to work in any browser

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:
Log into the site and select the file I want to download
Click download
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?
Are you sure you have the Java plugin enabled? e.g. 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
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 ).
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:
Verify your Java version will work with the applet you are accessing
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

“Your security settings have blocked a local application from running” Java 8

I am trying to run a small applet in my Chrome window, but am getting the error message.
I do see all the replies telling me to change my security to medium, but that option does not exist in version 8. So far several hours of googling and asking help from classmates has brought no progress.
Can anyone suggest something please?
Medium was removed in Java 8u20:
Medium (removed from Java 8 Update 20 and later versions)
Only unsigned applications that request all permissions are blocked. All other applications are allowed to run with security prompts. Selecting the Medium security level is not recommended and will make your computer more vulnerable should you run a malicious application.
Keep in mind, this only applies to unsigned applets that request all permissions.
What to do
To run these applets, you now must add the site to the exception list under the Security tab when you access your Java settings from the Control Panel.
If the applet is not on a website, you must use the applet viewer, which allows you to run applets outside of a browser

Java security warnings while loading applets

I have some issues while using some applet in my application. It's showing that i have untrusted applet, that my jar files are not allowed to be run, showing that they are also using an old version of java (I'm using java 1.7).
Do you have any solution, like maybe using a third-pary certificate ?
Anyway, thanks for your help.
Check if this helps. You will see more details here
Setting the Security levels through the Java Control Panel
In the Java Control Panel, click on the Security tab.
Select the desired Security level.
Click Apply.
Click OK to save changes made to the Java Control Panel.
Security levels in the Java Control Panel
Very High
This is the most restrictive security level setting. All the applications that are signed with a valid certificate and include the Permissions attribute in the manifest for the main JAR file are allowed to run with security prompts. All other applications are blocked.
High
This is the minimum recommended (and default) security level setting. Applications that are signed with a valid or expired certificate and include the Permissions attribute in the manifest for the main JAR file are allowed to run with security prompts. Applications are also allowed to run with security prompts when the revocation status of the certificate cannot be checked. All other applications are blocked.
Medium (removed from Java 8 Update 20 and later versions)
Only unsigned applications that request all permissions are blocked. All other applications are allowed to run with security prompts. Selecting the Medium security level is not recommended and will make your computer more vulnerable should you run a malicious application.
The part of "Resolution" in that website said.
"Since the issue is being reported by the Java software or the Java plugin in the browser, there is nothing we can do to directly resolve the issue.
There are several workarounds possible, depending on how the site deals with browser security issues.
The most secure approach is to allow the applet to be run each time you are prompted.
If using Internet Explorer, click the [Run] button on the security warning popup window.
If using Firefox, two actions may be needed. First if the warning "This connection is untrusted" is displayed, click the "I Understand the Risks""

Application blocked by security settings

I'm trying to play Java applets from bodo.com
but whenever I click on one of the games, I get a pop-up that says:
Application blocked by security settings
Name: "game"
Location: http://www.bodo.com
Your security settings have blocked an application from running with an
out-of-date or expired version of java.
I don't understand this because I have the latest version of Java installed.
I just had this problem myself. To solve this I went to the Windows Control Panel -> Programs -> Java. There you go to Security and press Edit Site List..., click Add and there you type in the location (http://www.bodo.com) and press OK.
If you still have problem you can try changing the Security Level to Medium and this you also manage under the Security tab in Java Control Panel.
For me, the exception site list helped when the applet is not signed or certified.
For out of date error, I need to change the security level to medium.
And make sure you close all the browser windows and start fresh after you made the changes.
The instruction here shows how to change security level: JCP security help on Java.com

Automation server can't create object - Microsoft JScript runtime error

I am trying to run a Java webstart application which is launched from a html page. While loading I get an alert with the message "Automation server can't create object" a couple of times after which the applications starts and works fine. The alerts come up only on one of the workstations. Any pointers on where I should look?
Regards,
Dutch
try the following IE setting: "Initialize and script ActiveX control not marked as safe."
May or may not apply to your case, but there are reported problems with the JScript Runtime throwing up errors when starting up Applets or Java WebStart applications when you have specific network settings.
Every now and again, there's a Windows Update that generates such a bug and another one that follows to fix it and you'll see some of these errors. Yours might be one of these.
Usually the workaround in-between is to either:
go to IE's Network Settings and uncheck "auto detect settings" or any PAC file setting
or go to the Java control panel's Network Settings and disable "Use browser settings" or other settings to use a direct connection instead.
Obviously, that workaround is only valid if you do not have to go through a proxy...
