The improved custom taglib works with existing facelet ui taglibs. For example:
<ui:param name="theName" value="John"/> <my:hel...produces the expected output. However, a problem exists with the ui:repeat tag:

http://localhost:8080/facelet-demo/?name=Zack&name...the raw EL prints out the correct names, but my custom tag substitutes empty string for theName2 ! In theory, the response is rendered in the Render Response phase, way after the Apply Request Values phase, actual values should be available to EL. The answer to this anomaly turned out to be very deep ! Yes, right there in the code! I would consider this a bug in facelets implementation, but the JSF spec did not tell what the expected behavior should be. In my custom...

The Android unit test framework is based on JUnit 3 , not JUnit 4. Test cases have to extend junit.framework.TestCase or a subclass (such as android.test.InstrumentationTestCase ). Tests are identified by public methods whose name starts with test , not methods annotated with @Test (as in JUnit 4). An Android test suite is packaged as an APK, just like the application being tested. To create a test package, first you need to identify the application package it is testing. Google suggests to put the test package source in a directory named tests/ alongside the src/ directory of the main application. At runtime, Android instrumentation loads both the test package and the application under test into the same process. Therefore, the tests can invoke methods on...

The root URL is: http://android.git.kernel.org/ Built-in applications are projects named platform/packages/apps/<app_name>.git , for example, phone app is: platform/packages/apps/Phone.git , contacts app is: platform/packages/apps/Contacts.git . Android framework classes such as android.app.Activity , android.content.ContentProvider etc., are under the platform/frameworks/base.git project. By default, browsing displays the HEAD branch, to see a different branch, add hb parameter. Compare: http://android.git.kernel.org/?p=platform/build.git;a=tree;f=tools to: http://android.git.kernel.org/?p=platform/build.git;a=tree;f=tools;hb=refs/tags/android-2.2.1_r1 , you'll notice that dexpreopt is missing in the former. Use the tags action to display a list of tags for the current project. For example: http://android.git.kernel.org/?p=platform/build.git;a=tags . An incomplete parameter list (parameters are separated by a semicolon): p : project, for example, platform/build.git . a : action, for example, tree , summary , log etc. f : file name. hb : branch or tag name, for example:...

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
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...
