How can I display error in JSP without a <form:form>

I have a jsp page with a List<Object> as the @ModelAttribute. However, there are no <form:form> tags in the page. All I'm doing is print the contents of the List.

In my Controller.java, I'm binding an error by doing:

result.rejectValue("", "NOT_LOGGED_IN", "You should Login first") ;

But since I dont have a form in my jsp, I'm not able to access the error with:

<form:errors path="" /> <br/>

Please tell me how to access the error (or what I'm doing wrong).

Check if Expression Language evaluation is enabled in JSP(By default it is disabled).If not add below code to enable it.

<%@ page isELIgnored="false" %>

there's a way to reference the error like

instead of

<form:form commandName="object">
     <form:errors path="field"/>
</form:form>

for any specific error set in your code like-

model.addObject("errorMsg","username/password failed");

And show this error on jsp in this way:

<c:out value="${errorMsg}"/>

This way you would get your error on jsp.

In your controller:

model.addAttribute("errors", result.getAllErrors());

In your JSP:

<c:forEach items="${errors}" var="error">
    <%-- do want you want with ${error} --%>
    <c:out value="${error.defaultMessage}" />
</c:forEach>

Associate global errors this way:

result.reject("NOT_LOGGED_IN", "You should Login first") ;

You can show the global errors in the jsp :

<form:errors cssClass="error" delimiter="&lt;p/&gt;" />
