LDAP Transaction Manager Eorror

Hello everybody~

After following the spring-ldap reference document, I implement my LDAP codes but got a error while configure the transaction for LDAP operations.

My configuration code is as following :

Code:

---

<beans>
  <!--
  LDAP Context Source
  -->
  <bean id="ldapContextSource" class="org.springframework.ldap.core.support.LdapContextSource">
        <property name="url" value="ldap://127.0.0.1:389" />
        <property name="base" value="dc=myWorld,dc=com,dc=cn" />
        <property name="userDn" value="cn=Root,dc=myWorld,dc=com,dc=cn" />
        <property name="password" value="123456" />
        <property name="pooled" value="false"></property>
  </bean>
  <!--
  LDAP Transaction Configuration
  -->
  <bean id="tranAwareContextSourceProxy"
            class="org.springframework.ldap.transaction.compensating.manager.TransactionAwareContextSourceProxy">
      <constructor-arg ref="ldapContextSource" />
  </bean>
 
  <bean id="transactionManager"
            class="org.springframework.ldap.transaction.compensating.manager.ContextSourceTransactionManager">
          <constructor-arg ref="tranAwareContextSourceProxy"></constructor-arg>
  </bean>

However, once the tomcat server startup, it runs into the following error:

Code:

---

1 constructor arguments specified but no matching constructor found in bean 'transactionManager' (hint: specify index and/or type arguments for simple parameters to avoid type ambiguities)

---

Why it shows this error?

In additionally, is there any simple samples or doucment on LDAP transaction manage?
I am still not very clear with how to implement the transaction by following the code in spring-ldap reference document .

Thanks in advanced.
