I am able to display the form, but I am not able to display the result from
the referenceData() function at all. can somebone please help me out please?
my controller code

import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.Statement;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.commons.beanutils.DynaBean;
import org.apache.commons.beanutils.RowSetDynaClass;
import org.apache.commons.lang.StringUtils;
import org.appfuse.webapp.controller.BaseFormController;
import org.hibernate.SQLQuery;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.validation.BindException;
import org.springframework.validation.Errors;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import com.sun.net.httpserver.Authenticator.Success;
import com.sun.org.apache.xerces.internal.impl.dv.xs.DayDV;
import local.tux.manufacture.model.Query;
public class QueryController extends BaseFormController {
public QueryController(){
setCommandName("query");
setCommandClass(Query.class);
}
protected Object formBackingObject(HttpServletRequest request) throws
Exception{
return new Query();
}
public ModelAndView onSubmit(HttpServletRequest request,
HttpServletResponse response,
Object command, BindException errors) throws Exception{
return showForm(request, response, errors);
}
@SuppressWarnings("unchecked")
protected Map referenceData(HttpServletRequest request, Object command,
Errors errors )throws Exception {
Map referenceData = new HashMap();
referenceData.put("result", "hello world");
return referenceData;
}
}
my jsp code
<%@ include file="/common/taglibs.jsp" %>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<c:set var="buttons">
<input type="button" style="margin-right: 5px"
onclick="location.href='<c:url value="result.html"/>'"
value="<fmt:message key="button.add"/>"
/>
</c:set>
<form:form commandName="query" method="post"
action="query.html" id="queryform" onsubmit="return
validateQuery(this)">
<form:errors path="*" cssClass="error" element="div" />
<form:hidden path="id" />
<ul>
<li>
<appfuse:label styleClass="desc" key="query.query" />
<form:errors path="query" cssClass="fieldError"/>
<form:textarea path="query" cssClass="text mediumn"/>
</li>
<li class="buttonBar bottom">
<input type="submit" class="button" name="save"
value="<fmt:message
key="button.run" />" />
<input type="submit" class="button" name="cancel"
value="<fmt:message
key="button.cancel"/>" />
</li>
</ul>
</form:form>
<ul>
<li>
<c:if test="${result}" >
has <c:out value="${result}" />
</c:if>
<c:if test="${results}" >
has <c:out value="${results}" />
</c:if>
</li>
</ul>
and the bean definition.
<bean id="queryController"
class="local.tux.manufacture.web.controller.QueryController">
<property name="successView" value="redirect:query.html"/>
</bean>
Thanks in advance.
