CurrCon Currency Converter

CurrCon Currency Converter

The CurrCon Java Applet displays prices on this web page converted with today’s exchange rates into your local international currency, e.g. Euros, US dollars, Canadian dollars, British Pounds, Indian Rupees… CurrCon requires an up-to-date browser and Java version 1.7 or later, preferably 1.8.0_11. If you can’t see the prices in your local currency, Troubleshoot. Use Chrome for best results.


CurrCon stands for Currency Converter.

The currency converter lets you display prices/amounts in the native currency of the visitors to your website. The currency converter automatically selects the default currency to display based on the locale country setting of the browser. It currently supports 169 different currencies.

Unlike most currency converters, with this one, the user does not enter amounts to be converted. The values come from your web page. All prices on your web pages are instantly displayed in the user’s favourite currency without him having to do anything. For more details see the manual. The Currcon Currency Converter is also available with Java source to download.

Java Requirements and Troubleshooting

If, CurrCon, the above Currency Converter Java Applet does not work…
  1. If Copy/Paste (Ctrl-C/Ctrl-V) do not work, you can turn them back on by modifying your java.policy file. This is not for the novice or faint of heart. instructions Your alternative is to download this program and run it without a browser.
  2. Often problems can be fixed simply by clicking the reload button on your browser.
  3. Make sure you have both JavaScript and Java enabled in your browser.
  4. This Java Applet needs 32-bit or 64-bit Java 1.7 or later. For best results use the latest 1.8.0_11. In the Java Control Panel, configure medium security to allow vanilla unsigned applets to run.
  5. You also need a recent browser.
  6. It works under any operating system that supports Java e.g. W2K/XP/W2003/Vista/W2008/W7-32/W7-64/W8-32/W8-64/W2012/Linux/LinuxARM/LinuxX86/LinuxX64/Ubuntu/Solaris/SolarisSPARC/SolarisSPARC64/SolarisX86/SolarisX64/OSX
  7. You should see the Applet above looking much like this screenshot. If you don’t, the following hints should help you get it working:
  8. Especially if this Applet has worked before, try clearing the browser cache and rebooting.
  9. To ensure your Java is up to date, check with Wassup. First, download it and run it as an application independent of your browser, then run it online as an Applet to add the complication of your browser.
  10. If the above Applet does not work, check the Java console for error messages.
  11. If the above Applet does not work, you might have better luck with the downloadable version available below.
  12. If you are using Mac OS X and would like an improved Look and Feel, download the QuaQua look & feel from UnZip the contained quaqua.jar and install it in ~/Library/Java/Extensions or one of the other ext dirs.
  13. If you are using Microsoft Internet Explorer 7, 8 or 9, try another browser. Seriously. Microsoft has taken great pains, over and over, to screw up Java and every other multi-platform standardisation.
  14. If you are using Microsoft Internet Explorer 7, 8 or 9, you must click to allow blocked content permission for Active X to run. This also gives permission to Java to run. Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java. Don’t put up with it! Use a different browser.
  15. If you are using Microsoft Internet Explorer 9, makes sure the Java Plug-In SSV helper add-in is installed and enabled. If it is not, try reinstalling the Java JRE.
  16. If you have Windows 7 64-bit and Internet Explorer 64-bit, in theory you can use 64-bit Java, but I never been able to get it to work.
  17. Try upgrading to a more recent version of your browser, or try a different browser e.g. Firefox, SeaMonkey, Safari or Avant.
  18. If you still can’t get the program working click HELP for more detail.
  19. If you can’t get the above Applet working after trying the advice above and from the HELP button below, have bugs to report or ideas to improve the program or its documentation, please send me an email atemail Roedy Green.
