Discover what JSF converters are and explore their role in web application development.
- [Instructor] A converter in JSF is a component…that will convert input supplied in the workpage…to a java object in your backing bean.…Let's look at a practical use case.…On our input component page, we have a few components here…that let us select a dessert and save our selection…to the backing bean.…Our selections on that page are saved to these long fields…we have one on line 25 for the select one radio,…we have one on line 27 for the select one menu selection.…
These IDs are supposed to be the…unique identifiers for each dessert object.…For these IDs to now become dessert objects again,…we have to do a look up using the ID…to find the right dessert and use it.…In our case we are simply looking up from an in-memory list.…In the real world, you're most likely retrieving that data…from a durable data store like a relational database.…What we'll now have is a separate method in our backing bean…that does nothing but look up desserts.…
This is the more traditional approach…to handling web applications requests in something…
