[Back to "Building real-time access to an LDAP directory server from your Notes application."]
The LDAPSearchWithFilter agent code
The following is the complete code example for the LDAPSearchWithFilter agent.
import lotus.domino.*;
import javax.naming.*;
import javax.naming.directory.*;
import java.util.Hashtable;
import java.util.Vector;
public class LDAPSearchWithFilter extends AgentBase {
public void NotesMain() {
try {
Database _db;
Document _doc;
Session session = getSession();
AgentContext agentContext = session.getAgentContext();
_db = agentContext.getCurrentDatabase();
// Used for running agent on server with docID being passed from the calling action
Agent ag1 = agentContext.getCurrentAgent();
String paramid = ag1.getParameterDocID();
Document doc = _db.getDocumentByID(paramid);
String searchCN = doc.getItemValueString("SearchCN");
String searchAttr = doc.getItemValueString("SearchAttr");
// Set up the environment for creating the initial context
String ldapCF = "com.sun.jndi.ldap.LdapCtxFactory";
String ldapURL = "ldap://myldap.mycompany.com:389/";
String ldapBaseDN = "ou=myou, o=myorg, c=us";
String ldapUserID = "cn=Administrator";
String ldapPassword = "thepassword";
Hashtable env = new Hashtable(4);
env.put(Context.INITIAL_CONTEXT_FACTORY, ldapCF);
env.put(Context.PROVIDER_URL, ldapURL + ldapBaseDN);
env.put(Context.SECURITY_PRINCIPAL, ldapUserID);
env.put(Context.SECURITY_CREDENTIALS, ldapPassword);
try {
// Create initial context
DirContext ctx = new InitialDirContext(env);
String[] attrIDs = {searchAttr};
SearchControls ctls = new SearchControls();
ctls.setReturningAttributes(attrIDs);
// Specify the search filter
String filter = "(|(cn="+searchCN+")(uid="+searchCN+"))";
// Search for objects using the above filter
NamingEnumeration answer = ctx.search("", filter, ctls);
findCN(answer, doc);
// Close the context when we're done
ctx.close();
} catch(NamingException e) {
e.printStackTrace();
}
} catch (Exception e) {
}
} // end of NotesMain
public static void findCN(NamingEnumeration enum, Document doc) {
try {
if (enum.hasMore()) {
while (enum.hasMore()) {
SearchResult sr = (SearchResult)enum.next();
System.out.println(">>>" + sr.getName());
findAttrs(sr.getAttributes(), doc);
}
} else {
Item item = doc.getFirstItem("HiddenSearchResults");
doc.replaceItemValue("HiddenSearchResults", "CN not found");
doc.save(true);
}
} catch (NamingException e) {
} catch (Exception e) {
}
} // end of findCN
public static void findAttrs(Attributes attrs, Document doc) {
try {
Item item = doc.getFirstItem("HiddenSearchResults");
Vector v = new Vector();
String result;
if (attrs.size() == 0) {
v.addElement("Name found but attribute is blank or not found. Try again ...");
} else {
/* Get each attribute */
try {
for (NamingEnumeration ae = attrs.getAll(); ae.hasMore();) {
Attribute attr = (Attribute)ae.next();
/* Get each value */
for (NamingEnumeration e = attr.getAll(); e.hasMore();) {
result = (String)e.next();
v.addElement(result);
}
}
} catch (NamingException e) {
}
} // end if
doc.replaceItemValue("HiddenSearchResults", v);
doc.save(true);
} catch (Exception e) {
}
} // end of findAttrs
The Search LDAP button code
The following is the complete code example for the Search LDAP button.
Sub Click(Source As Button)
Dim s As New NotesSession
Dim ws As New NotesUIWorkspace
Dim db As NotesDatabase
Dim agent As NotesAgent
Dim doc As NotesDocument
Dim uidoc As NotesUIDocument
Dim searchResultItem As NotesItem
Dim paramid As String
Set db = s.CurrentDatabase
Set uidoc = ws.CurrentDocument
Set doc = uidoc.Document
Set agent = db.GetAgent("LDAPSearchWithFilter")
Call doc.save(True, False)
paramid = doc.NoteID
Call agent.RunOnServer(paramid)
Delete doc
Set doc = db.GetDocumentByID(paramid) ‘ retrieve the back-end document
'Get the updated field
Set searchResultItem = doc.getFirstItem("HiddenSearchResults")
Forall values In searchResultItem.Values
Call uidoc.FieldAppendText("SearchResults", values)
‘ Add new line, for results that have multi values
Call uidoc.FieldAppendText("SearchResults", Chr(10))
End Forall
Call uidoc.Refresh
doc.Remove(True) ‘you do not want to keep the back-end doc
End Sub
The Entering event code for the SearchCN field
The following is the code example for the Entering event of the SearchCN field.
Dim ws As New NotesUIWorkspace
Dim uidoc As NotesUIDocument
Set uidoc = ws.CurrentDocument
Call uidoc.FieldSetText("SearchCN", "")
Call uidoc.FieldSetText("SearchAttr", "")
Call uidoc.FieldSetText("SearchResults", "")
Call uidoc.FieldSetText("SearchResultsGroup", "")
Call uidoc.FieldSetText("HiddenSearchResults", "")
If uidoc.FieldGetText("SearchType") = "Group" Then
Call uidoc.FieldSetText("SearchAttr", "member")
End If
Call uidoc.Refresh
The Exiting event code for the SearchCN field
The following is the code example for the Exiting event of the SearchCN field. The code is similar to the code for the Search LDAP button, but with additional string processing as follows:
'Get the updated field
Set searchResultItem = doc.getFirstItem("HiddenSearchResults")
Forall values In searchResultItem.Values
pos1 = Instr(Cstr(values), "=")
pos2 = Instr(Cstr(values), ",")
stringValue =Mid(Cstr(values), pos1+1, pos2-pos1)
Call uidoc.FieldAppendText("HiddenSearchResults", stringValue)
End Forall
