When you invoke a form handler, you must present it with a set of values as functional parameters. These values are the data that would be submitted in form fields if the form handler were being invoked from a user interface. Different types of form handlers require different parameters depending on the function they perform. See more information about form handlers in the Page Developer's Guide.

For example, the /atg/store/profile/RegistrationFormHandler form handler requires a java.util.Dictionary property named value that holds a set of dictionary fields. The fields in the dictionary property hold the values that would be entered in user interface fields on a registration form. To invoke the /atg/store/profile/RegistrationFormHandler form handler, you must include a functional parameter for value.email, value.password, value.confirmPassword, value.firstName, and value.lastName.

The following JSON data contains the functional parameters required by the /atg/store/profile/RegistrationFormHandler form handler.

{ "value.email":"sheroux@example.com", "value.password":"mypassword",
"value.confirmPassword":"mypassword", "value.firstName":"Severe",
"value.lastName":"Heroux" }
