my controller:


public class ProfilesController extends MultiActionController {
private ProfileManager profileManager;
private PermissionManager permissionManager;
...
public ModelAndView create(HttpServletRequest request,
HttpServletResponse response) throws Exception {
ModelMap model = new ModelMap();
List<Permission> permissions = permissionManager.getPermissionList();
model.addAttribute(new Profile());
model.addAttribute(permissions);
return new ModelAndView("profile", "commandName", model);
}


my jsp:


<form:form method="POST" action="add.htm" commandName="commandName">
<%@ include file="/WEB-INF/jsp/headerDetails.jsp"%>
<table width="645" border="0">
<tr>
<th class="styleHeader" colspan="2" scope="col"><spring:message
code="profile" /></th>
<th width="10" scope="col">&nbsp;</th>
<th class="styleHeader" width="349" scope="col"><spring:message
code="permissions" /></th>
</tr>
<tr>
<td><label><spring:message code="name" />*</label></td>
<td><form:input path="name" size="32" maxlength="30" /> <br>
<form:errors path="name" cssClass="styleErrorMessage" /></td>
<td>&nbsp;</td>
<td><label> <input type="checkbox" name="checkbox"
id="checkbox" /> Test</label></td>
</tr>
...


Why when try to show my jsp I get the next error:

org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/profile.jsp at line 25

22: </tr>
23: <tr>
24: <td><label><spring:message code="name" />*</label></td>

27: <td>&nbsp;</td>
28: <td><label> <input type="checkbox" name="checkbox"

I'm assuming name is a member of the Profile object, so change the path from 'name' to 'profile.name'.
