# SOAP Test: Is It a Prime Number

The number typed in the text field will change color depending upon whether the soap call reports prime or nonprime.

This works by calling a SOAP service listed on X Methods Website. View the source of this page for details on how it was called. If you compile mozilla DEBUG, the message sent and received will be logged to the console.

Experimenters may wish to add other tests which exercize services, with specific user interfaces such as the one in this test.
