You can actually host GCalc 3 on your own web site. Follow these steps.
  1. Download these two files: gcalc3.jar and gcalc3-custom.jnlp.txt.
  2. Change the name of gcalc3-custom.jnlp.txt to gcalc3-custom.jnlp.
  3. Edit gcalc3-custom.jnlp to reflect your web environment. Specifically, replace ####A#### (in the 4th line) with the codebase URL. It should be the URL of the directory where these files will end up.
  4. Create a link to your gcalc3-custom.jnlp file in your web page.
  5. Upload the pertinent files, including gcalc3-custom.jnlp and gcalc3.jar
  6. Test the link to see if it works.
  7. If it doesn't, check to see if the web server is configured correctly to return the proper MIME type for the JNLP content. The MIME type must be application/x-java-jnlp-file. If you're unsure what I'm talking about, ask the system administrator of the web server.
Although not required, please include a link to http://gcalc.net.

Good luck!
