my user model class traditional following-

package org.ravij.model;      public class user {          private string username;         private string password;         private boolean isadmin;          public boolean isadmin() {             return isadmin;         }          public void setadmin(boolean isadmin) {             this.isadmin = isadmin;         }          public string getusername() {             return username;         }          public void setusername(string username) {             this.username = username;         }          public string getpassword() {             return password;         }          public void setpassword(string password) {             this.password = password;         }     } 

i getting below exception, while running hibernate v4.2-

caused by: org.hibernate.propertynotfoundexception: not find getter isadmin in class org.ravij.model.user     @ org.hibernate.property.basicpropertyaccessor.creategetter(basicpropertyaccessor.java:316)     @ org.hibernate.property.basicpropertyaccessor.getgetter(basicpropertyaccessor.java:310)     @ org.hibernate.mapping.property.getgetter(property.java:321)     @ org.hibernate.tuple.entity.pojoentitytuplizer.buildpropertygetter(pojoentitytuplizer.java:436)     @ org.hibernate.tuple.entity.abstractentitytuplizer.<init>(abstractentitytuplizer.java:200)     @ org.hibernate.tuple.entity.pojoentitytuplizer.<init>(pojoentitytuplizer.java:82) 

below hibernate mapping configuration file-

<hibernate-mapping package="org.ravij.model">      <class name="user" table="users">         <id name="username" type="string" column="user_name" length="20">             <generator class="assigned" />         </id>         <property name="password" type="string" column="password" />         <property name="isadmin" column="admin" type="boolean" />     </class>  </hibernate-mapping> 

why getting error "could not find getter boolean" , changes required?

following javabean naming convention, property name "admin". "isadmin" name of accessor method property.
