  an LDAP association LdapContext ctx = new InitialLdapContext(); // Activate paged results int pageSize = 20; // 20 entries per page byte[] cookie = null; int total;}ctx.setRequestControls(new Control[] new PagedResultsControl(pageSize, Control.CRITICAL) }); do { // Perform the search NamingEnumeration results = ctx.search("", "(objectclass=*)", new SearchControls()); // Iterate over a batch of search results while (results != null && results.hasMore()) { // Display an entry SearchResult entry = (SearchResult)results.next(); System.out.println(entry.getName()); System.out.println(entry.getAttributes()); // Handle the entry's response controls (if any) if (entry instanceof HasControls) { // ((HasControls)entry).getControls(); } } // Examine the paged results control response Control[] controls = ctx.getResponseControls(); if (controls != null) { for (int i = 0; i < controls.length; i++) { if (controls[i] instanceof PagedResultsResponseControl) { PagedResultsResponseControl prrc = (PagedResultsResponseControl)controls[i]; total = prrc.getResultSize(); cookie = prrc.getCookie(); } else { // Handle other response controls (if any) } } } // Re-activate paged results ctx.setRequestControls(new Control[]{ new PagedResultsControl(pageSize, cookie, Control.CRITICAL) }); } while (cookie != null); // Close the LDAP association ctx.close(); ... }

  This class implements the LDAPv3 Control for paged-results as defined in RFC 2696. The control's value has the following ASN.1 definition:

   {@code}realSearchControlValue ::= SEQUENCE  size      INTEGER (0..maxInt), -- requested page size from client -- result set size estimate from server cookie    OCTET STRING } }
