The user chooses their desired color from the color palette provided. The tag can be used to add a color palette to a Facelet.Ĭomponent for picking colors. The advantages of this are twofold: as well as allowing the user to pick any color, it also lets them the see the color itself on the screen. This component allows the user to pick colors from a color palette. The PrimeFaces library offers a special component for choosing colors, the color picker. There, we defined the need for the view to contain colorpicker controls that can only return valid color values. The optimization process refers back to the requirements. We are going to use PrimeFaces to rectify this current disadvantage of our application.
If the user wishes to select a color at will, however, this input component is highly unsuitable. In situations where a limited choice of colors will suffice, this approach can work. The combo boxes display a text representation of the colors with their hexadecimal values. The URL of the donation form is displayed in a text area and adjusts itself automatically to account for the currently selected color (see Fig. Combo boxes are provided in the form to enable the user to choose their desired background and text color. Now that we have access to the PrimeFaces library, the first improvement we want to make relates to the Facelet editDonationForm.xhtml – the input screen for the use case Edit donation form. 10.2 New Choice of Colours for Editing the Donation Form The XML namespace for the PrimeFaces tags is: xmlns:p="" and has to be declared in each Facelet using PrimeFaces components. Please refer to the PrimeFaces documentation if necessary. Īnd that’s it! We can begin using the PrimeFaces tags in the Facelets immediately. To this, we must amend the file with a dependency. Since we’re managing our project configuration with Maven, we must adjust a few settings in the pom.xml file to enable Maven to use the desired version of PrimeFaces. The JAR file must be available in the project and the Facelet must be provided with the correct namespace: these are essentially the only two things required to enable us to use the library’s tags.
#PRIMEFACE VS ICEFACES VS RICHFACES ARCHIVE#
The library is considered lightweight due to it consisting of just a single Java archive (JAR file) and due to the fact that no particular configuration is required and it has no dependencies to other libraries. PrimeFaces is a JSF component library offering a number of very useful extensions. My-Campaign after Chapter 8 (Remaining Use Case) We will use PrimeFaces for our project.Īgain, you can continue to work in your own Codenvy workspace or you can use the following project state in a temporary workspace. Though the simultaneous use of multiple additional libraries is possible, it is usually advised against to preserve the UI’s visual consistency. Popular additional libraries are Apache MyFaces, ICEFaces, RichFaces and PrimeFaces. However, the ongoing standardization of JSF has made the development and use of additional libraries noticeably simpler.
#PRIMEFACE VS ICEFACES VS RICHFACES PROFESSIONAL#
These components are often insufficient for the implementation of a professional web application. Though JSF provides a framework for the development of web applications, it provides only a limited number of UI components. The following digression will look at PrimeFaces as an example. The use of external JSF libraries is necessary to enable us to do this. However, we want to get the most out of our web application that we possibly can. We have managed to fulfil the majority of our web application user interface requirements using the JSF Standard.
