JSP custom tags example with body

Created by Fang on January 28, 2012 13:24:09 Last update: January 28, 2012 13:31:22

This is a simple JSP custom tags library with tag body. Just like the JSF counterpart , it splits a string and repeats the body for each word, i.e., with this markup: <%@ taglib uri="http://custom.tag.com/demo" prefix... output:

<html>
 
 <body>
 
 	<p>Hello Tigger!</p>
 
 	<p>H...

Using tag handler, UI component and renderer with a JSF facelet taglib

Created by Fang on November 22, 2011 10:40:16 Last update: November 22, 2011 10:40:16

This is an example that uses tag handler, UI component and renderer together to support a custom taglib. The main purpose is to show how these components play together. The tag renders

<ui:param name="extra" value="el interpreted"/>
 
...

 <ul class="css class" extra...

JSF facelet taglib backed by a UI component

Created by Fang on November 08, 2011 20:55:00 Last update: November 21, 2011 18:19:44

In the simple taglib example , I used a tag handler class to implement a taglib. This is an example to implement a taglib with a UI component. The purpose is to use a custom tag to split a string and print each part in a separate paragraph, i.e., print john steve mike with custom tag <my:foreach> : <my:foreach var="who" value="john steve mike"> ... These are the files: pom.xml <project xmlns="http://maven.apache.org/POM/4.0.0"... src/main/java/com/example/UIForeash.java : package com.example; import java.io.IOExcep... src/main/resources/META-INF/faces-config.xml : <?xml version="1.0" encoding="UTF-8"?> <faces-c... src/main/resources/META-INF/foreach.taglib.xml : <?xml version="1.0" encoding="UTF-8"?> <facelet... How to use: Put the JAR file generated by the above project in the WEB-INF/lib folder of the web app. If the web app is a Maven project, just add the taglib project as a dependency:...

Java utility to generate insert statements for Oracle

Created by Dr. Xi on January 07, 2010 23:40:28 Last update: February 09, 2010 03:24:35

This is a utility to generate SQL insert statements for Oracle for one table, or a set of tables. It doesn't cover all possibilities but should be good enough for most cases.

import java.io.*;
 
 import java.sql.*;
 
 import ...

To generate insert statements for multiple tables, simply put the table names in a file, one per line, and use the -f switch.
