  1. Tony Nguyen Intro to Javaserver Faces

  2. Architecture • Advantages • Disadvantages • Setup JSF Environment • JSF & Database • Conclusion • Demo

  3. Architecture • A standard API for creating Java Web Application GUIs. • Allow Java programmers to develop application without HTTP details and integrate it with user interface through event-driven model. • JSF based on Model-View-Controller (MVC) design pattern. • Drag and drop UI components to build web application. (EIS)

  4. Advantages • Less code. • Custom GUI controls. • Form validation. • Event handling. • Managed beans. • Expression Language.

  5. Disadvantages • Less transparent. • Harder to learn. • Not enough documentation. • Rigid approach. • Undeveloped tool support.

  6. JSF & Event Driven • <h:form> • <!-- For non graphical browsers --> • <p>Example of <code>commandLink</code></p> • <h:panelGrid id="links" columns="4" • summary="#{bundle.chooseLocale}" • title="#{bundle.chooseLocale}" > • <h:commandLink id="NAmerica" action="storeFront" • actionListener="#{carstore.chooseLocaleFromLink}"> • <h:outputText value="#{bundle.english}" /> • </h:commandLink> • </h:panelGrid> • </h:form>

  7. Expression Language <c:if test=“${result.rowCount == 0}”> Sorry, no products match your criteria </c:if> <c:if test=“${result.rowCount != 0}”> These products were found <ul> <c:forEach items=“${result.rows}” var=“row”> <li>${row.prodName}</li> </c:forEach> </ul> </c:if>

  8. Setup JSF Environment • Java 2 Software Development Kit. • Enabled web-server Tomcat 5. • JSF 1.0 implementation(Sun’s Reference Implementation).

  9. JSF & Database • Standard JDBC • JSTL • Hibernate

  10. Conclusion • JSF can provide many useful features for developing complex GUIs and handling events. • MVC for web development. • Huge industry and vendor support.
