Some innocent looking JavaScript may cause a fatal error in a Facelet page. For example: <script type="text/javascript"> if (items.lengt... or <script type="text/javascript"> // jQuery code ... Because Facelet is strict XML, therefore, < and > must be escaped. There are several ways to deal with this: Do not embed JS code directly in the page. Put the code in .js files and include it in the page with the src attribute. Put JS code in a CDATA section: <h:outputScript target="head"> <![CDATA... Use XML entities: <script type="text/javascript"> // jQuery code ...

In this note I'll show you how to create and package a JSP custom tag. The purpose of this tag is to display a random splash image for a home page, among a set of images. We should be able to add or delete candidate splash images from the WAR archive without the need to change the JSP. This is the intended use of the tag: <%@ taglib uri="http://custom.tag.com/demo" prefix... In the above example you provide a set of images named splash*.png (e.g., splash1.png, spalsh2.png, ...), and the tag will pick a random one to display when the JSP is rendered. Let's get started. I'll use Maven for this purpose. Create the standard Maven directory structure ./pom.xml ./src ./src/main ./src/main/jav... pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... SplashTag.java package tagdemo; import java.util.ArrayList......

You can use applet , object , or embed tags to embed an applet in your HTML page. However, The applet tag is interpreted by both IE and Mozilla family of browsers. The applet tag won't automatically download a JRE if the Java Plug-in isn't already installed. The object tag works only for IE The embed tag works only for Mozilla family of browsers, i.e., Firefox. Use applet tag: <applet code="MyApplet.class" width="200" ... Use object tag: <!-- latest JRE --> <OBJECT classid="clsid:... Use embed tag: <!-- highest JRE that supports MIME type ... Mixed object and embed tag: <object classid="clsid:8AD9C840-044E-11D1-B3E9... You need to use a different name for the Mozilla embed tag and use that name to refer to the applet...
