Error with Spring ldap pooling - spring-data

Question

i build async jersey web services, and now i need to make some operations with ldap.
I have configure Spring beam.xml in this mode:
<bean id="contextSourceTarget" class="org.springframework.ldap.core.support.LdapContextSource">
<property name="url" value="${ldap.url}" />
<property name="base" value="${ldap.base}" />
<property name="userDn" value="${ldap.userDn}" />
<property name="password" value="${ldap.password}" />
<property name="pooled" value="false" />
</bean>
<bean id="contextSource"
class="org.springframework.ldap.pool.factory.PoolingContextSource">
<property name="contextSource" ref="contextSourceTarget" />
</bean>
<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
<constructor-arg ref="contextSource" />
</bean>
<bean id="ldapTreeBuilder" class="com.me.ldap.LdapTreeBuilder">
<constructor-arg ref="ldapTemplate" />
</bean>
<bean id="personDao" class="com.me.ldap.PersonDaoImpl">
<property name="ldapTemplate" ref="ldapTemplate" />
</bean>
But when i try to use ldap i have this error:
Error creating bean with name 'contextSource' defined in class path resource [config/Beans.xml]: Instantiation of bean failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/pool/KeyedPoolableObjectFactory
In my project i have commons-pool2-2.2.jar lib, but still i have this error..i try to add commons-pool2-2.2.jar in TOMCAT_PATH/lib but not works..
UPDATE:
If i put commons-pool-1.6.jar it works.. but if i want to use pool2 how i can do? only i must change class inn commons-pool2-2.2.jar?

Updated Answer:
Since at least Spring LDAP 2.3.2 you can now use commons-pool2. Spring LDAP now provides two classes:
For commons-pool 1.x:
org.springframework.ldap.pool.factory.PoolingContextSource
For commons-pool 2.x:
org.springframework.ldap.pool2.factory.PooledContextSource
Details can be found here:

Original Answer:
Unfortunately Spring-Ldap uses commons-pool and not commons-pool2. As you have found the class org.apache.commons.pool.KeyedPoolableObjectFactory does not exist in commons-pool2 (it has a different package structure), hence the error.
There is a Jira issue for the Spring-ldap project asking them to upgrade/support commons-pool2:
https://jira.spring.io/browse/LDAP-316
Until that has been completed you will have to use commons-pool 1.6.
