The kind of the java solutions offered to the IT sector is amazing these days. There has been a lot of java development happening these days with the increased number of outsource java development taking place. Facelets are one such java solutions tool, which is very powerful. It helps to organize and ensure java development projects become more efficient. Outsource java development team can avoid a catastrophe when they use facelets for devising innovative java solutions.
Here the various features that are either under used or newly introduced that is beneficial to java development.
Leveraging f of the ui: decorate
The ui: decorate allows the outsource java development team to change the skin from almost anything in the JSF page. Say for example the form fields are usually separated with the help of the section containers so with this ui: decorate try to give some charm to that by giving some attractive skins.

Now let us explain java development with the help of an example. Take the word "Hello Faceltes". Let's assume you want to decorate this text. You want it to have a green background ...
... and also a border should surround the background, which is green in color. This is how the coding needs to be done to get the desired result in Java solutions.
Listing 1. /WebContent/example/example1.xhtml
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html">

<body>

<h:form>

<ui:decorate template="/WEB-INF/widget/formDecorator.xhtml">Hello Facelets!</ui:decorate>...</h:form>

</body>

</html>
From the above it is very clear that one needs to only add two more lines extra in the coding to get the effect. So it is better to decorate the page as it will be more effective. So whatever you want to decorate see to that it is placed between the tags <ui:decorate...> and </ui:decorate>

A simple text can be decorated easily.
It is not difficult to include the form fields to the page and also decorate in the same way under Java development. The hello facelets should be just is replaced with the form fields that need to be decorated. The listing 2 in the decorator will have the form field decorator option. There will be templates which will be helpful in making the desired effect. To get the green effect the style sheet can be used. One can also choose to add some images that are very elite at the border of the form field. As the outsourced java development team modifies the decorator they will keep getting new affect every time with new color and skin. Given below is the coding give to decorate the form fields as part of Java solutions.
Listing 2. /WEB-INF/widget/formDecorator.xhtml
