If you have problems running Java applets. . .

Paul B. Andersen

To run a Java applet, you must have a Java enabled internet browser. As far as I know the only browsers able to run Java applets are Internet Explorer in Windows, and Safari in Mac. You may have to enable the Java plugin. Note that Internet Explorer may be 32 bit even if  Windows is 64 bit.

You must have the Java runtime environment (JRE) installed, preferably the latest version. If not, get it here

Be sure to install the correct version. If you have a 32-bit operating system, install the 32-bit  JRE. If you have a 64-bit operating system, I will recomend to install both the 32-bit and  the 64-bit  JRE. That is because if you have a 32-bit internet browser you will need the 32-bit JRE. Install both, they will not disturb each other.

When you try to run one of the Java applets on my website, you are likely to get the message that the page is blocked by security reasons. To overcome this problem, you must open the Java control panel.

If you have WIN 7 you will find it in the Windows control panel, search for "Java". 

If you have WIN 8.1 or WIN 10 hit the start button -> all apps -> Java -> Configure Java.

Select the tab "Security" and the control panel  will look something like this:


The default setting is "High", you may set it to "Very High", if you wish. 

 Click "Edit Site List", and you will get this panel:


Click "Add", and add the item: "", like this:


Click "OK" twice, and you will be allowed to run the applets on my web-page.

 Running Windows 10?

If you are are using the internet browser Microsoft Edge you will not be able to run Java. You can however start the browser Internet Explorer from Edge. Hit the three dots on the top right, and select "Open with Internet Explorer".

How safe is it to run the applets?

An unsigned Java applet is run in a restricted mode, it will for example not be able to access  files on your computer.  And my website is secure (HTTPS) which means that it has a SSL certificate issued by  Bitdefender   and all communication with the website is encrypted. And if you look at the top of this page you will see that my domain "" is secured by  SiteLock , the global leader in website security,  which means that my website is scanned every day, and if the shield says "passed" it is guaranteed free of malware. (Click on the shield to see the guarantee.)  But the best security lies in the fact that both the SSL certificate and SiteLock guarantee that the 'Company'  Paul B. Andersen is genuine. And what's more, to get a ".no" domain you must apply to Norid   . The result of a whois lookup in Norid can be found here.

I would have to pretty stupid if I had  malicious programs on my website which can be tracked back to me.

So I will answer the question above like this:

It's very safe.
