In this Struts example, you will learn how to create a HTML input tag of type reset with Struts <html:reset> tag. In order to use the Struts HTML Tags you need to include the following taglib directive in the jsp page.
<%@taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
First create a new Dynamic Web Project and configure it as Maven Project. For Reference, Click Here
Add the following dependencies in pom.xml
<dependencies> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.8.2</version> <scope>test</scope> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts-core</artifactId> <version>1.3.10</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts-taglib</artifactId> <version>1.3.10</version> </dependency> </dependencies>
1. Create JSP
Now we will create a HTML input tag of type reset using Struts’s HTML tag
Write the following code in reset.jsp
<%@taglib uri="http://struts.apache.org/tags-html" prefix="html"%> <html> <head> <title>Struts <Html:reset> Button</title> </head> <body> <html:reset value="Reset" /> </body> </html>
Now create another JSP output.jsp that display the dropdown value. Write the following code in output.jsp
<%@page contentType="text/html" pageEncoding="UTF-8"%> <%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Output Page</title> </head> <body> Selected Fruit - <bean:write name="StrutsDropDownForm" property="fruit" /> </body> </html>
2. Struts Config
Write the following code in struts-config.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts-config PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN" "http://jakarta.apache.org/struts/dtds/struts-config_1_3.dtd"> <struts-config> </struts-config>
3. Deployment Descriptor
Now configure the deployment descriptor. Here, we have asked the container to give our ActionServlet any request that matches the pattern *.do
Add the following configuration information in the web.xml file
<welcome-file-list> <welcome-file>reset.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-class> org.apache.struts.action.ActionServlet </servlet-class> <init-param> <param-name>config</param-name> <param-value>/WEB-INF/struts-config.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>action</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping>
4. Run Project
