I am getting an error when i configure ldap with spring app



mvn code

	<dependency>
			<groupId>org.springframework.ldap</groupId>
			<artifactId>spring-ldap-core</artifactId>
			<version>1.3.0.RELEASE</version>
		</dependency>
		<dependency>
			<groupId>org.springframework.ldap</groupId>
			<artifactId>spring-ldap-core-tiger</artifactId>
			<version>1.3.0.RELEASE</version>
		</dependency>

spring config

	<!-- Ldap configurations  -->
   <bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
      <property name="url" value="ldap://se-gmolinar-dt1.wdig.com:10389/ou=system" />
        <property name="userDn" value="uid=admin,ou=system"/>
        <property name="password" value="secret" />
   </bean>

   <bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
      <constructor-arg ref="contextSource" />
   </bean>
   
    <bean id="adminServiceTarget"
        class="com.AdminServiceImpl">
       
    
       <property name="ldapTemplate" ref="ldapTemplate" />
    </bean>

and the implementation class has following code

	
private LdapTemplate ldapTemplate;


	
	public LdapTemplate getLdapTemplate() {
		return ldapTemplate;
	}


	public void setLdapTemplate(LdapTemplate ldapTemplate) {
        this.ldapTemplate = ldapTemplate;
    }

but when i start the app in tomcat 6. I get the error.
