Question

I have a list containing users. I am trying to print it in JSP but some how I am not able to get it to print it. Getting this exception HTTP Status 500 - javax.servlet.ServletException: javax.servlet.jsp.JspTagException: Neither BindingResult nor plain target object for bean name 'users[0]' available as request attribute

Code in JSP

<c:forEach items="${users}" var="user" varStatus="status">
   <spring:bind path="users[${status.index}].name">
      <c:out value="${status.value}" />
   </spring:bind>
</c:forEach>

Controller

ModelAndView modelAndView = new ModelAndView("go_some_JSP_page");
List<UserEntity> users = userManager.getAllObjects();
modelAndView.addObject("users", users);

BTW, UserEntity has name field. If I remove the binding and try to print the user.name using <c:out value="user.name" /> it prints the value

Where am I going wrong and what do I need to do? Thanks

Not working code below. [I have to invoke formatting on field @NumberFormat so have to try it using status variable]

<spring:bind path="user.name">
   <c:out value="${status.value}" />
</spring:bind>

Gets this error –> javax.servlet.ServletException: javax.servlet.jsp.JspTagException: Neither BindingResult nor plain target object for bean name 'user' available as request attribute

So added a bean binding and then I get empty table :(. I believe thats because the instance is empty. So this does not seems like a right approach.

@ModelAttribute("user")
public UserEntity userEntityBinding() {
    return UserEntity.newInstance();
}

A working code exists at https://github.com/hth/StatusInvoke.git

Let me know if you face any problem deploying it.

This question has been solved. Thanks for looking at it.

Answer 1

The correct answer to invoke @NumberFormat annotation is by using spring:eval expression tag

<spring:eval expression="user.balance" />

This invokes the annotation and performs formatting as mentioned in the annotation
