Property 'someproperty' not found on type java.lang.String

I am getting this error and I can not figure out where the problem might be. The "userid" column is in the database and is in the bean. Does anyone have any idea? 

org.apache.jasper.JasperException: An exception occurred processing JSP page /user.jsp     at line 24  

21:   
22:     <form method="POST" action="AdminServlet" name="frmAddUser">  
23:         User ID : <input type="text" readonly="readonly" name="userid"  
24:             value="<c:out value="${user.userid}" />" />   
Username : <input  
25:             type="text" name="firstName"  
26:             value="<c:out value="${user.firstName}" />" />   
LastName : <input  
27:             type="text" name="lastName"  

root cause   

javax.el.PropertyNotFoundException: Property 'userid' not found on type java.lang.String

Thank you.

Are you doing a <c:set var="user">${user}</c:set> anywhere on the jsp?

According to Response 1 on another question, JSP does an implicit conversion to a string when you set the var in the JSP.

The exception is basicaly telling you that ${user} is an ordinary java.lang.String. According to the javadoc, it has indeed no getUserid() method representing an userid property.

Make sure that you're setting a concrete User instance in the desired scope instead of a plain vanilla String. As you haven't shown anywhere in the question how you're preparing the scoped variable, it isn't possible to give a targeted answer on that, but it should at least look something like this:

User user = userService.find(id);
request.setAttribute("user", user); // and thus not e.g. setAttribute("user", "user") or something.

One of the following should be the case, according to me

  • The userid data-type is not matching with the one corresponding in the bean. It might be integer in db.

  • The property is not defined in the bean class. The name might be different, and you must be inferring it to be userid.
