BeanCreationException

[tylerperkins]

I am following the reference guide by Arthursson and Sandberg that comes with Spring-Ldap 1.1.2, but have had no luck getting it to work. I think I might be missing some knowledge that is assumed by the document. Here is my app. context.


<!-- LDAP Settings-->
<bean id="contextSource"
class="org.springframework.ldap.support.LdapContextSource">
<property name="url" value="ldap://persona.tu.ir:389"/>
<property name="base" value="dc=tu,dc=ir"/>
<property name="userName" value="cn=something"/>
<property name="password" value="secret"/>
<property name="dirObjectFactory" value="org.springframework.ldap.support.DefaultDirObjectF actory" />
</bean>
<bean id="ldapOperations" class="org.springframework.ldap.LdapTemplate">
<constructor-arg ref="contextSource" />
</bean>
<bean id="LdapUserDao" class="taxonomy.dao.spring.SpringLdapUserDao">
<property name="ldapOperations" ref="ldapOperations"/>
</bean>


I think I may be having a library issue, but not sure, these are the libraries that I am using right now for spring.

spring.jar (v2.0)
spring-ldap-1.1.2.jar
commons-collections.jar
commons-lang.jar
commons-logging.jar
ldapbp.jar
spring-orm.jar


Finally this is the error that I am getting.

Do I need to have a class to initialize the contextSource (like a LdapServerManager) or is that something that spring takes care of? In the sample program that comes with spring-ldap they have something like this:


<bean name="ldapServerManager" class="org.springframework.ldap.LdapServerManager">
<property name="contextSource" ref="contextSource" />
<property name="ldifFile" value="setup_data.ldif" />
</bean>
which I assume is what I'm missing.

any help would be appreciated.

Thanks,

I would say you have the wrong version of commons-lang. Make sure you use commons-lang 2.1.

With regards to the usage of LdapServerManager, that's just an internal helper class that we used to simplify the bootstrapping of an in-memory ApacheDS LDAP-server for our integration tests and our sample application.

It is likely that a newer version of commons-lang is required; your present version doesn't appear to have a required method.

Hey thanks guys, that did the job. Ive been updating libraries and have found that it is not a very fun job. I've successfully upgraded from struts 1.1 to struts 2.0 and spring 1.1 to spring 2.0. Now I will attempt to update Hibernate.

Thanks again,

Hello, there,

I got the same error, I upgraded the commons-lang to commons-lang-2.3jar and still got the same error. Do I have to upgrade anything else to get it work? How do you find out the spring version?

Thanks!

[ulsa]

You will find the version of all Spring jars in the META-INF/MANIFEST.MF file.

I just verified that the integration tests and the person sample works fine with commons-lang 2.3.
