Modify catalog.jsp to output a message that a catalog entry has been
created and modify error.jsp to output a message that an error has been
generated in updating the database.
148 7 Ajax with JSF-Ajax4jsf
7.6 Processing an Ajax Request
On the server-side the Catalog ID field value is validated with the database
table Catalog. If the Catalog ID value is already specified in the database a
validation message, ???Catalog Id is not valid??? gets displayed in the input
form. If the Catalog ID value is not already specified in the database, a
validation message, ???Catalog ID is valid??? gets displayed in the input form.
We have used the business logic that if a catalog id is not already defined
the catalog id is valid. Additional business logic may be added to check if
the catalog id matches a pattern specified in a regular expression. The
inputText_action method gets invoked when a value is specified in
the Catalog ID input field. An Ajax request is sent with each modification
in the Catalog ID input field.
