Grails find / findAll operation won't work?

Question

Hello all,

I'm trying to build a Grails application which can do LDAP lookups. I've been following a few guides (link text and some others) but to no end I'm afraid.

Relevant source code: From config.groovy:

ldap {
directories    { 
    dir1 {
        url = "ldap://dc01"
        base = "ou=someou,dc=check,dc=nl"
        userDn = "cn=Administrator,cn=Users,dc=check,dc=nl"
        password = "wowthisisnothepassword"
    }
}

schemas = [
    ldapclient.GldapoSchemaClassForUser
]}

My domainclass:

package ldapclient
import gldapo.schema.annotation.GldapoNamingAttribute
import gldapo.schema.annotation.GldapoSynonymFor
import gldapo.schema.annotation.GldapoSchemaFilter

@GldapoSchemaFilter("(objectclass=person)")
class GldapoSchemaClassForUser {
   @GldapoNamingAttribute
   String uid

   @GldapoSynonymFor("cn")
   String name

   @GldapoSynonymFor("mail")
   String email

   @GldapoSynonymFor("uid")
   String username

   @GldapoSynonymFor("fullname")
   String fullName
}

And my controller:

package ldapclient

class AdController {
def defaultAction = "list"

List matches = GldapoSchemaClassForUser.findAll(
    filter: "(name=s*)"
)

def list = {
    [ "adMatches" : matches.list() ]
}}

Although my program conforms (for as far as I can tell) to what should work according to the many documents, I cannot run this. The error thrown:

Caused by: groovy.lang.MissingMethodException: No signature of method: static ldapclient.GldapoSchemaClassForUser.findAll() is applicable for argument types: (java.util.LinkedHashMap) values: [[filter:(name=s)]] at ldapclient.AdController.(AdController.groovy:6)*

Any clues what's going on / wrong? I'm on Grails 1.2.3 and using the most current version of the LDAP plugin. The project is clean (freshly created).

Thanks in advance!

According to documentation, findAll method has only this definitions (where Book - is sample domain class):

Book.findAll()
Book.findAll( String query )
Book.findAll( String query, Collection positionalParams )
Book.findAll( String query, Collection positionalParams, Map paginateParams )
Book.findAll( String query, Map namedParams )
Book.findAll( String query, Map namedParams, Map paginateParams )
Book.findAll( Book example )

And your code:

List matches = GldapoSchemaClassForUser.findAll(
    filter: "(name=s*)"
)

Could be rewritten as:

List matches = GldapoSchemaClassForUser.findAllByNameLike("s%")

Or use criteria definition:

List matches = GldapoSchemaClassForUser.list() {
     like("name","s%")
}

To use filters - look at Hibernate-filter plugin

Where are your schema classes located? I have this plugin working fine (albeit with Grails 1.3.4). Note that your link to the plugin is an old-ish page. Here is the latest I believe: Grails LDAP Plugin.

Don't think there's much difference other than it looks like you can drop schema classes in the grails-app/ldap directory instead of having to specify them in Config - I do it the same way as you with schemas specified in the config, but might be worth trying them in the grails-app/ldap folder?

Thanks for the response; I just upgraded to Grails 1.3.4 and moved some files around. This did some good, though I still get this nasty error:

Error creating bean with name 'ldapclient.AdController': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [ldapclient.AdController]: Constructor threw exception; nested exception is groovy.lang.MissingMethodException: No signature of method: static ldapclient.GldapoSchemaClassForUser.findAll() is applicable for argument types: (java.util.LinkedHashMap) values: [[directory:dir1, filter:(uid=myname,ou=st,ou=ouou,dc=dc,dc=dcdc)]] Possible solutions: findAll(groovy.lang.Closure), find(groovy.lang.Closure)
