Running 3270 terminal emuator applet

Connection Information

In the options box you will need to use

If the applet does not launch check that your web browser has java support. FireFox and Chrome and all derivitives no longer supports java applets, you need Safari or windows Internet Explorer.

Basically too much work, much easier for windows users to use the wc3270 emulator.

Note: most modern browsers no longer support applets. A lot of google or bing searching will show you that Internet Explorer is the only browser that still supports them. It is however possible for users of the Edge browser on Windows 10 to run applets. It is not possible using the Linux version of Edge as it does not provide an IE compatability setting.

  1. start the Edge browser
  2. under settings/default-browser enable IE compatability mode, this will then give you a menu option to reload a page in IE compatability mode
  3. go to https://java.com and the page will say its not suitable for Edge, reload the page in IE compatability mode. You can then download java and install it; do so
  4. From the start menu locate the java contraol panel, run it. Update the security settings to whitelist the website addresses of any site you want to run a java applet from; this is not enough if the applets want to open connections back to the website (such as a 3270 terminal applet does)
  5. Aslo you then need to to run "notepad" as an Administrator, edit the file C:\Program Files(X86)\java\version\lib\security\java.policy and add lines within the grant section for each of the sites that you want to allow an applet to connect to such as the below which will let the applet connect to this site on port 3270. 
       permission java.net.SocketPermission "mdickinson.dyndns.org:3270", "connect", "resolve";
  6. restart Edge and you should be good to go
