constructor issues for LdapAuthenticationProvider.

[farrellr]

I'm trying various ways to integrate acegi security with spring-ws.
I've managed to use plain text and hashed password with memory and dao.

Now I'm trying to work on Ldap. Since LdapAuthenticationProvider is a provider (rather than a userDetailsService) I'm only trying to get it work with plain text passwords.

I declare ldapAuthProvider in my applicationContext.xml as follows:

<bean id="ldapAuthProvider" class="org.acegisecurity.providers.ldap.LdapAuthenticationProvider" >
<constructor-arg index="0">
	<bean class="org.acegisecurity.providers.ldap.authenticator.BindAuthenticator">
	<constructor-arg><ref local="initialDirContextFactory" />
             </constructor-arg>
  	<property name="userSearch" ref="userSearch" /> 
  	</bean>
  	</constructor-arg>
	<constructor-arg index="1">
	<bean class="org.acegisecurity.providers.ldap.populator.DefaultLdapAuthoritiesPopulator">
              <constructor-arg>
              <ref local="initialDirContextFactory" />
              </constructor-arg>
							<constructor-arg>
             <value>CN=Groups,DC=utdtest,DC=com</value>
             </constructor-arg>
	<property name="groupRoleAttribute">
             <value>cn</value></property>
              </bean>
	</constructor-arg>
</bean>

which has 2 constructor arguments, and the constuctor from the java looks like this:

        public LdapAuthenticationProvider(LdapAuthenticator authenticator,
              LdapAuthoritiesPopulator authoritiesPopulator) {
        this.setAuthenticator(authenticator);
        this.setAuthoritiesPopulator(authoritiesPopulator);
    }

So it seems that bean instantiation should work, however I get the error:
...
Caused by:
org.springframework.beans.BeanInstantiationExcepti on: Could not instantiate bean class [org.acegisecurity.providers.ldap.LdapAuthenticatio nProvider]: No default constructor found; nested exception is java.lang.NoSuchMethodException: org.acegisecurity.providers.ldap.LdapAuthenticatio nProvider.<init>()

at org.springframework.beans.BeanUtils.instantiateCla ss(BeanUtils.java:148)
...

any idea why? I'm not sure if this is an acegi issue, spring-ws, or something I'm doing wrong - any advice?

I'm posting this to both the acegi and spring-ws forums.
Thanks for any help.

My problem was I had another bean declared with no arguments (even though I wasn't using it for anything, of course spring was trying to create it).
Sorry for the post.
