Hi,
Can someone kindly reply as to what is the issue in my code and why am I getting the exception mentioned in my previous post ...I am not sure how to resolve the same...

Thanks.

Hi,
I am trying Spring MVC for the first time(in fact I am quite new to Spring also). I tried this so many times for the past one day but still getting the same issue, even after looking at the suggested link and also other google search results. I am using the Spring mvc tutorial available at:

http://static.springsource.org/docs/Spring-MVC-step-by-step/part4.html

Following is the error:

org.apache.jasper.JasperException: An exception occurred processing JSP page /index.jsp at line 16 13: <h1><fmt:message key="heading"/></h1> 14: 15: <form:form name="searchForm" method="POST" action = "/SearchAccessServlet.do" commandName="searchAccess"> 16: <!--<form:input path="kopsId" /> 17: <form:errors path="kopsId" cssClass="error"/>--> 18: <br><br> 19: <input type="submit" value="Submit" /> Stacktrace: org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:510) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:413) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) root cause java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'searchAccess' available as request attribute org.springframework.web.servlet.support.BindStatus.<init>(BindStatus.java:141) org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.getBindStatus(AbstractDataBoundFormElementTag.java:172) org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.getPropertyPath(AbstractDataBoundFormElementTag.java:192) org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.getName(AbstractDataBoundFormElementTag.java:158) org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.autogenerateId(AbstractDataBoundFormElementTag.java:145) org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.resolveId(AbstractDataBoundFormElementTag.java:136) org.springframework.web.servlet.tags.form.AbstractDataBoundFormElementTag.writeDefaultAttributes(AbstractDataBoundFormElementTag.java:120) org.springframework.web.servlet.tags.form.AbstractHtmlElementTag.writeDefaultAttributes(AbstractHtmlElementTag.java:379) org.springframework.web.servlet.tags.form.InputTag.writeTagContent(InputTag.java:139) org.springframework.web.servlet.tags.form.AbstractFormTag.doStartTagInternal(AbstractFormTag.java:90) org.springframework.web.servlet.tags.RequestContextAwareTag.doStartTag(RequestContextAwareTag.java:77) org.apache.jsp.index_jsp._jspx_meth_form_005finput_005f0(index_jsp.java:225) org.apache.jsp.index_jsp._jspService(index_jsp.java:114) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:377) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260) javax.servlet.http.HttpServlet.service(HttpServlet.java:717) note The full stack trace of the root cause is available in the Apache Tomcat/6.0.26 logs.

Following is the code in SearchAccessFormController:

Following is the code in SearchAccess.java:

package com.service; import java.io.Serializable; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; /** * @author corp * */ public class SearchAccess implements Serializable { private String name; public String getname() { return name; } public void setname(String name) { this.name = name; } }

Following is the code in SearchAccessImpl:

/** * */ package com.service; import java.util.ArrayList; import java.util.List; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; /** * @author corp * */ public class SearchAccessServiceImpl implements SearchAccessService { private static final long serialVersionUID = 1L; private static final Log LOGGER = LogFactory.getLog(SearchAccessServiceImpl.class); public List<?> searchAccess(final String name){ LOGGER.info("Entered searchAccess"); return new ArrayList(); } }

Following is the index.jsp code:

<html> <%@ include file="/WEB-INF/jsp/include.jsp" %> <%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %> <%@ page import="com.util.*" %> <head><title><%out.println(PropertyUtil.getProperty("title")); %><fmt:message key="title"/></title> <style> .error { color: red; } </style> </head> <body onLoad="javascript:searchForm.field.focus()"> <h1><fmt:message key="heading"/></h1> <form:form name="searchForm" method="POST" action = "/SearchAccessServlet.do" commandName="searchAccess"> <form:input path="name" /> <form:errors path="name" cssClass="error"/> <br><br> <input type="submit" value="Submit" /> </form:form> </body> </html>

I checked BindStatus.java in Spring code, but unable to find why target is null. The exception above is in index.jsp...Please help
