spring - Bean definition is abstract Error on a Standalone Java application -

im trying create parentdao handle connection details standalone java application.
when run program error below

exception in thread "main" org.springframework.beans.factory.beanisabstractexception: error creating bean name 'parentdao': bean definition abstract

what doing wrong? know abstract class following examples used abstract classes. abstract parentdao class , 1 dry spring bean im totally lost specially on how on standalone application. , initialize applicationcontext , how.

below connection properties (bean.xml)

<?xml version="1.0" encoding="utf-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xsi:schemalocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">      <bean id="datasource" destroy-method="close"         class="org.apache.commons.dbcp.basicdatasource">         <property name="driverclassname" value="oracle.jdbc.driver.oracledriver" />         <property name="url" value="jdbc:oracle:thin:@ipaddress:1521:habagat" />         <property name="username" value="username" />         <property name="password" value="password" />     </bean>      <bean id="parentdao" class="com.mercury.dao.parentdao" abstract="true">         <property name="datasource" ref="datasource" />     </bean>     <bean id="childdao" class="com.mercury.dao.childdaoimpl" parent="parentdao"/>         </beans> 

below main method

public static void main(string[] args) {     applicationcontext context = new classpathxmlapplicationcontext(         "beans.xml"); parentdao parentdao = (parentdao) context.getbean("parentdao"); } 

and parent dao class

   public abstract class parentdao<t> extends jdbcdaosupport {          public abstract void insert(t object) throws exception;          public abstract void delete(int id) throws exception;          public abstract void update(t object) throws exception;          public abstract t select(int id) throws exception; } 

my service

public class myservice {      childdao childdao;      public string getchildrencount() {           return int totalcount = childdao.getrecordcount();     } } 

well, parent dao is abstract. why try pull bean out of context? want childdao bean.
