Question

I´m new in this little world, and I´m trying to develope a Spring Ldap Transaction and I have serious problems with the Spring bean creation.

I have this config XML file:

<bean id="ldapContextSource" class="org.springframework.ldap.core.support.LdapContextSource">
    <property name="url" value="ldap://localhost:10389" />
    <property name="base" value="dc=***,dc=com" />
    <property name="authenticationSource" ref="authenticationSource" />
    <property name="pooled" value="false" />
    <property name="baseEnvironmentProperties">
        <map>
            <entry key="com.sun.jndi.ldap.connect.timeout" value="500" />
            <entry key="java.naming.referral" value="follow" />
        </map>
    </property>
</bean>

<bean id="authenticationSource"
    class="org.springframework.ldap.authentication.DefaultValuesAuthenticationSourceDecorator">
    <property name="target" ref="springSecurityAuthenticationSource" />
    <property name="defaultUser" value="uid=admin,ou=system" />
    <property name="defaultPassword" value="secret" />
</bean>

<bean id="springSecurityAuthenticationSource"
    class="org.springframework.security.ldap.authentication.SpringSecurityAuthenticationSource" />

<bean id="ldapTransactionContextSource"
    class="org.springframework.ldap.transaction.compensating.manager.TransactionAwareContextSourceProxy">
    <constructor-arg ref="ldapContextSource" />
</bean>

<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
    <constructor-arg ref="ldapTransactionContextSource" />
</bean>

<bean id="transactionManager"
    class="org.springframework.ldap.transaction.compensating.manager.ContextSourceTransactionManager">
    <property name="contextSource" ref="ldapTransactionContextSource" />
</bean>

<bean id="userDaoTarget" class="com.***.daos.UserDao">
    <property name="ldapTemplate" ref="ldapTemplate" />
</bean>

<bean id="userDao"
    class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
    <property name="transactionManager" ref="transactionManager" />
    <property name="target" ref="userDaoTarget" />
    <property name="transactionAttributes">
        <props>
            <prop key="*">PROPAGATION_REQUIRES_NEW</prop>
        </props>
    </property>
</bean>

And I have problems when the “userDaoTarget” bean is created because it trows this exception:

java.lang.NoClassDefFoundError: org.springframework.beans.FatalBeanException
    at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.instantiateBean(AbstractAutowireCapableBeanFactory.java:997)

    at org.springframework.context.support.FileSystemXmlApplicationContext.<init>(FileSystemXmlApplicationContext.java:140)
    at org.springframework.context.support.FileSystemXmlApplicationContext.<init>(FileSystemXmlApplicationContext.java:84)

Finaly my UserDao.class is the next code:

public class UserDao extends CommonDao implements ICommonDao<User> {

    private LdapTemplate ldapTemplate;

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

Can someone help me with the bean creation? I think that the code is correct but i dont know what happens…

Thanks all for your time

What Spring dependencies do you have on your classpath? Specifically, do you have the

org.springframework.beans-<version>.jar

artifact?
