LDAP: error code 2 - paged results cookie is invalid

[janko33]

I am trying to get paged results from OpenLdap
first page runs without difficulties but with second I got invalid cookie error

to get the list I use this:

def PagedResult listEm(PagedResultsCookie cookie) {

final int PAGE_SIZE = 1;
PagedResultsDirContextProcessor pageProcessor = new PagedResultsDirContextProcessor(PAGE_SIZE, cookie);

SearchControls searchControls = new SearchControls();
searchControls.setSearchScope(SearchControls.SUBTR EE_SCOPE);
searchControls.setReturningObjFlag(true);

List people = ldapTemplate.search("", "(objectclass=person)", searchControls, new PersonAttributesMapper(), pageProcessor);

return new PagedResult(people, pageProcessor.getCookie());
//return ldapTemplate.search( "", "(objectclass=person)",new PersonAttributesMapper())

}

def result = listEm(null);
PagedResultsCookie prCookie = result.getCookie();
def peopleList = result.getResultList();

result = listEm(prCookie); //errror

It's probably getting a new connection on the second run, thus loosing the cookie. When I test PagedResults, I configure the context source like this:

<bean id="contextSource" class="org.springframework.ldap.core.support.SingleContextSource">
   <constructor-arg ref="context" />
</bean>
	 
<bean id="context" factory-bean="contextSourceTarget" factory-method="getReadOnlyContext" />
	 
<bean id="contextSourceTarget" class="org.springframework.ldap.core.support.LdapContextSource">
   <property name="urls" value="${urls}" />
   <property name="base" value="dc=jayway,dc=se" />
   <property name="userDn" value="${userDn}" />
   <property name="password" value="${password}" />
</bean>

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

Be careful, though. Stepping away from the comfort of the automatic closing of resources in LdapTemplate can be risky.

Hi

I have two questions:
The search method

	public PagedResult getAllPersons(PagedResultsCookie cookie) {
		final int PAGE_SIZE = 10;
		
		PagedResultsDirContextProcessor pager = new PagedResultsDirContextProcessor(PAGE_SIZE, cookie);

		//SortControlDirContextProcessor sorter = new SortControlDirContextProcessor("uid");

		AggregateDirContextProcessor processor = new AggregateDirContextProcessor();
		//processor.addDirContextProcessor(sorter);
		processor.addDirContextProcessor(pager);

		
		SearchControls searchControls = new SearchControls();
		searchControls.setSearchScope(SearchControls.SUBTREE_SCOPE);
		searchControls.setReturningObjFlag(true);

		AndFilter filter = new AndFilter();
		filter.and(new EqualsFilter("objectClass", "Person"));
		
		List people = ldapTemplate.search(DistinguishedName.EMPTY_PATH, filter.encode(), searchControls, getContextMapper(), processor);

		return new PagedResult(people, pager.getCookie());
		 }

It's ok.
How can I get total of the ldap base?
I have more than 3000 entry.

And I can't sort by cn or uid for example.
How can I do this?
