How to access a boolean value on a object using JSTL

I have a User object defined as follows:

public class User implements Serializable {
         private String userId;
         private boolean writeRole;
      
      public User(String userId, boolean writeRole) {
            this.userId = userId;
            this.writeRole = writeRole;
      }
      
      public String getUserId() {
            return userId;
      }
      
      public boolean hasWriteRole() {
            return writeRole;
      }      
}

I have added an instance of this object to the httpsession.
in the JSP I am using JSTL to retrieve the writeRole property:

<c:if test="${sessionScope.adminuser.readRole}" >

This is throwing a compiler error javax.servlet.jsp.el.ELException: Unable to find a value for "writeRole" in object of class "com.examples.User" using operator "."

how can I access this value using JSTL?

Thanks In advance
