While clicking on submit button controller is not handling the command

**deepakdhanwani** · Dec 8th, 2008, 01:28 AM

Hello all,

I am new to springframework. I am doing few R&D over this from last one month. I am facing a very stupid problem now a days. The problem is not so big, it is only with simple SimpleFormController. Before describing the problem, i want that please have a look on to the following code.

Web.xml

Code:

<servlet>
		<servlet-name>retailmart</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>
	
	<servlet-mapping>
		<servlet-name>retailmart</servlet-name>
		<url-pattern>*.htm</url-pattern>
	</servlet-mapping>

retailmart-servlet.xml

Code:

  <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
		<property name="mappings">
			<props>
				<prop key="/welcome.htm">welcomeController</prop>
				<prop key="/measurementmaster.htm">measurementMasterController</prop>
			</props>
		</property>
	</bean>

	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
		<property name="prefix" value="/WEB-INF/jsp/"/>
		<property name="suffix" value=".jsp"/>
	</bean>
	
	<bean id="welcomeController" class="com.deepak.controllers.WelcomeController"></bean>
	<bean id="measurementMasterValidator" class="com.deepak.validator.MeasurementMasterValidator"></bean>
	<bean id="measurementMasterController" class="com.deepak.controllers.MeasurementMasterController">
		<property name="sessionForm">
			<value>true</value>
		</property>
		<property name="commandClass">
			<value>com.deepak.beans.MeasurementMasterBean</value>
		</property>
		<property name="commandName">
			<value>measurementMaster</value>
		</property>
		<property name="formView">
			<value>measurementmaster</value>
		</property>
		<property name="successView">
			<value>welcome.htm</value>
		</property>
		<property name="validator">
			<ref bean="measurementMasterValidator"/>
		</property>
	</bean>

MeasurementMasterBean.java

Code:

  package com.deepak.beans;

public class MeasurementMasterBean {

	private int measurementMasterId;
	private String measurementMasterCode;
	private String measurementMasterName;
	
	public String getMeasurementMasterCode() {
		return measurementMasterCode;
	}
	public void setMeasurementMasterCode(String measurementMasterCode) {
		this.measurementMasterCode = measurementMasterCode;
	}
	
	public int getMeasurementMasterId() {
		return measurementMasterId;
	}
	
	public void setMeasurementMasterId(int measurementMasterId) {
		this.measurementMasterId = measurementMasterId;
	}
	
	public String getMeasurementMasterName() {
		return measurementMasterName;
	}
	
	public void setMeasurementMasterName(String measurementMasterName) {
		this.measurementMasterName = measurementMasterName;
	}
}

MeasurementMasterController.java

Code:

  package com.deepak.controllers;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import org.springframework.web.servlet.view.RedirectView;

public class MeasurementMasterController extends SimpleFormController{

	public ModelAndView onSubmit(Object command) throws Exception {
		return new ModelAndView(new RedirectView(getSuccessView()));
	}

}

WelcomeController.java

Code:

  package com.deepak.controllers;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class WelcomeController implements Controller{

	public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
		// TODO Auto-generated method stub
		return new ModelAndView("welcome");
	}
}

welcome.jsp

Code:

  <html>
	<head>
		<title>Welcome</title>
	</head>
	<body>
		<h1>WELCOME
	</body>
</html>

measurementmaster.jsp

Code:

  <%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<html>
	<head>
		<title>
			Measurement Master
		</title>
	</head>
	<body>
		<form method="post">
			<table width="372" height="211">
				<tr>
					<td>
						ID
					</td>
					<spring:bind path="measurementMaster.measurementMasterId">
					<td>
						<input type="text" name="measurementMasterId" value=""/>
					</td>
					</spring:bind>
				</tr>
				<tr>
					<td>
						ID
					</td>
					<spring:bind path="measurementMaster.measurementMasterCode">
					<td>
						<input type="text" name="measurementMasterCode" value=""/>
					</td>
					</spring:bind>
				</tr>
				<tr>
					<td>
						ID
					</td>
					<spring:bind path="measurementMaster.measurementMasterName">
					<td>
						<input type="text" name="measurementMasterName" value=""/>
					</td>
					</spring:bind>
				</tr>
			</table>
			<input type="submit" value="Insert"/>
		</form>
	</body>
</html>

As I think and I have seen in many examples, this code is absultely correct and should work properly, but it is not working fine.
As per my requirement when i click on "Insert" button in "easurementmaster.jsp"page, it should redirect me to the "welcome.jsp". But it not redirecting me there.
Please help me sort out this problem.

...in measurementmaster.jsp so it won't post to where you want it to go.

In made change in JSP according to your guidance, but still in vien.

Code:

<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>
<html>
	<head>
		<title>Measurement Master</title>
	</head>
	<body>
		<form action="measurementmaster.htm" method="post">
			<table>
				<tr>
					<td>
						Id
					</td>
					<spring:bind path="measurementMaster.measurementMasterId">
						<td>
							<input type="text" name="measurementMasterId" value="${status.value}"/>	
						</td>
					</spring:bind>
				</tr>
				<tr>
					<td>
						Code
					</td>
					<spring:bind path="measurementMaster.measurementMasterCode">
						<td>
							<input type="text" name="measurementMasterCode" value="${status.value}"/>	
						</td>
					</spring:bind>
				</tr>
				<tr>
					<td>
						Code
					</td>
					<spring:bind path="measurementMaster.measurementMasterName">
						<td>
							<input type="text" name="measurementMasterName" value="${status.value}"/>	
						</td>
					</spring:bind>
				</tr>
			</table>
			<input type="submit" value="Execute"/>
		</form>
	</body>
</html>

I used processFormSubmission function instead of onSubmit function. Now I am able to redirect from measurementmaster.jsp to welcome.jsp. onSubmit and doSubmitAction functions are not working at all.
