Some of the prominent features that you come across while using Facelets are Leveraging ui:decorate, help with simplifying the form field validation processes and ui:include helps you control various form fields with ease. Performing under tight schedules isn't just tedious but at times even seems impossible and that's not all, there are various other requirements that need to be met whilst designing software's using JSF. JSF development user could make use of the great features made available by Facelets.

Leveraging ui:decorate a feature of Facelets

Java development team can now skin almost everything present in any JSF page with the help of Facelets ui:decorate. Just place the content you wish to decorate within appropriate tags and your task is complete. If you wish to alter these skins at any time in the future then just change the decorator codes and your content gets a great new look, so your forms don't need to have the same stagnant look anymore. The ui:decorate code isn't just for adding attractive skins to your forms, but it is more prominent when it comes to widget creation. Now Java developers can create not just useful widgets but awesome looking ones as well.

Simplifying Form Field Validation with the help of Facelets

The built in validators present in JSF i.e. version 1.2 and its predecessors had just limited features to offer therefore most of the customised validation had to be manually done by the Java development team. This task may not be hard at all, but at times doing it manually can be frustrating. Luckily for us we now have an easy way out; Facelets gives us the opportunity to create our very own custom validators. These custom validators are much easier to handle as they are less complicated. More importantly the custom validators that you create accept any number of arguments that you pass on to it.

Once this is done, Facelets comes in the picture and automatically takes care of connecting the various attributes that are available in the JSF tag directly into your custom validator's class field name. To completely understand these concept Java developers should be familiar with the use of regex custom validator as this idea itself is extended and curtailed to meet individual project needs.

Getting Form Fields Under Control With ui:include

Java development team often come across instances wherein the same form field needs to be placed in multiple locations on a single form, however each of these fields requires complex and tedious validations as well as client side behaviour. Facelets template reuse feature is very helpful in times like this.

Review:

Therefore Facelets comes as a boon to Java developers, saving them time and energy by providing efficient and faster solutions to daily problems.
