Adding Tiles in your Struts Project

March 22nd, 2009 kumarasamy No comments
Tiles is a framework for the development user interface. Tiles is enables the developers to develop the web applications by assembling the reusable tiles (jsp, html, etc..). Tiles uses the concept of reuse and enables the developers to define a template for the web site and then use this layout to populate the content of the web site. For example, if you have to develop a web site having more that 500 page of static content and many dynamically generated pages. The layout of the web site often changes according to the business requirement. In this case you can use the Tiles framework to design the template for the web site and use this template to populate the contents. In future if there is any requirement of site layout change then you have to change the layout in one page. This will change the layout of you whole web site
Steps To Create Tiles Application
Tiles is very useful framework for the development of web applications. Here are the steps necessary for adding Tiles to your Struts application:
  1. Add the Tiles Tag Library Descriptor (TLD) file to the web.xml.
  2. Create layout JSPs.
  3. Develop the web pages using layouts.
  4. Repackage, run and test application.
Add the Tiles TLD to web.xml file
Tiles can can be used with or without Struts. Following entry is required in the web.xml file before you can use the tiles tags in your application. 
		<jsp-config>
			<taglib>
				<taglib-uri>/WEB-INF/struts-tiles.tld</taglib-uri>
				<taglib-location>/WEB-INF/struts-tiles.tld</taglib-location>
			</taglib>
		</jsp-config>
Struts-Config.xml Changes 
		<plug-in className="org.apache.struts.tiles.TilesPlugin" >
			<set-property property="definitions-config" value="/WEB-INF/tiles-defs.xml" />
			<set-property property="moduleAware" value="true" />
		</plug-in>
The above configuration will add Tiles support in your project.My tiles definition as follows in tiles-defs.xml 
			<definition name="IT.rootLayout" path="/rootLayout.jsp">
				<put name="topBanner" value="top.html"/>
				<put name="leftMenu" value="leftMenu.html"/>
				<put name="Desktop" value="Desktop.jsp"/>
				<put name="footer" value="footer.html"/>
			</definition>
In the above code i have defined a Tile element, IT.rootLayout. The page is rootLayout.jsp and it has four components, Which is topBanner,leftMenu,Desktop,footer.My rootLayout.jsp will look like the following. 
		<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
		<%@ taglib uri="/WEB-INF/struts-tiles.tld" prefix="tiles" %>
			<html:html locale="true">
			<head>
				<title>Test Tiles</title>
			</head>
			<body>
			<table width="100%" cellspacing="0" cellpadding="0" border="1">
			<tr>
				<td><tiles:insert attribute="topBanner"/></td>
			</tr>
			<tr>
				<td><tiles:insert attribute="leftMenu"/></td>
			</tr>
			<tr>
				<td>
					<table cellspacing="0" cellpadding="0" border="1" width="100%">
					<tr valign="top">
						<td ><tiles:insert attribute="Desktop" /></td>
					</tr>
					</table>
				</td>
			</tr>
			<tr>
				<td><tiles:insert attribute="footer"/></td>
			</tr>
		</table>
		</body>
		</html:html>
To call the tile component IT.rootLayout, i”m going to add the following definition in struts-config.xml 
		<action path="/IT.rootLayout" forward="IT.rootLayout"/>
We are done!!!! We have added a Tile definition and pages also

Apache Commons-Email

March 5th, 2009 kumarasamy No comments
Apache Commons has many built-in utils. One of the most used util is Commons-Email. Couple of week back had a situation need to send a mail to the users from my application. So i ended here.
The implementation is very simple. Commons-Email is built on top of the Java Mail API.
Some of the mail classes that are provided are as follows:
  • SimpleEmail-This class is used to send basic text based emails.
  • MultiPartEmail-This class is used to send multipart messages.
  • HtmlEmail-This class is used to send HTML formatted emails.
  • EmailAttachment-This is a simple container class to allow for easy handling of attachments.
The following piece of code will send an mail by using Commons-Email 
				package com.techmaddy;

				import org.apache.commons.mail.HtmlEmail;
				public class MailMan {
					public static void main(String[] args) {
						try {
							HtmlEmail email = new HtmlEmail();
							email.setHostName("mysmtp.server.com");
							email.addTo("test@test.com", "KMK");
							email.setFrom("admin@ttext", "Admin");
							email.setSubject("WARNING::Be Aware of this");
							email.setHtmlMsg("<b>Read this from techmaddy.com</b>");
							email.send();
						}
						catch(Exception e) {
							e.printStackTrace();
						}
					}
				}
If you SMTP Server needs authentication 
email.setAuthentication("username", "password");
For more ref Commons-Email
