Com.sun.jndi.ldap

Hi,
Is anyone familiar with JNDI LDAP automatic discovery codes
env.put(Context.PROVIDER_URL,
ldap:///o=JNDITutorial,dc=example,dc=com);
It seems that by using DNS that associate with multiple domain controllers, it would lock out user account if they enter wrong pw because LDAP provider will send the request to each of the associated DC at the same time. I wonder if anyone run through this issue and if it is a JDK bug and if someone does, how to you work around it?
Thanks,
Jennifer

Hi,
did you also try the following timeout variables?
env.put("com.sun.jndi.dns.timeout.initial", "2000");
env.put("com.sun.jndi.dns.timeout.retries", "3");...
Besides you specific problem you will find a probably interesting article about handling network timeouts her:

NullPointerException at com.sun.jndi.ldap.Connection.run(Connection.java:52

We are using the Sun jndi 1.2.1 files from a Java client to
access the IBM SecureWay Directory 3.2 server. Our test case is
retrieving entries using the ctx.getAttributes (String, String[])
method. Occasionally we are receiving the following error.
java.lang.NullPointerException
at com.sun.jndi.ldap.Connection.run(Connection.java:525)
at java.lang.Thread.run(Thread.java:481)
The java.lang.NullPointerException is coming from the Sun JNDI file.
Our program is not catching this exception.
Has anyone seen this problem before and have any ideas on how this can be resolved?

Download and use LDAP 1.2.3 or JDK 1.3.1.
The problem should go away.

Message: Cannot begin session. com/sun/jndi/ldap/ctl/PagedResultsControl

When I try to request a simple reuest (getversion) from the drm wsdl I receive an error in the XML repsonse (see below).
I read somewhere in the forum that I have to change the external direcortory provider in HSS from "MSAD" to LDAP/OID. But this can not be configured in HSS since I can not change the ID attribute (its greyed out).
Does anyone knows how I can sole it: I think its related to: "message: Cannot begin session. com/sun/jndi/ldap/ctl/PagedResultsControl"
Perhaps wrong or missing jar files in the connection configuration?
Any help is welcome.

Thanks for the repsonse.
Its exactly how you explain it.
Last thing I am dealing with (as var as I can see now) is getting a (generic/other) ldap connection in HSS to our MSAD.
HSS userinterface comes up with an error just before showing the user list. (on the serverside I traced traffic (wireshark) and see that userinformation is indeed retrieved).
But the frontend is juist not showing/ loading the information.
the error"a communication error occured when loading the view pane" Than the screen keeps on loading for ever
Oracle support tries to find out whats going wrong here.

Need javadoc for com.sun.jndi.ldap.ctl.*?

Hi,
has anybody the javadoc for the above named package?
I need at first com.sun.jndi.ldap.ctl.SortKey.
It is needed to get a sorted search result from a LDAP server.
Thank you for your help.

Download the LDAP provider at
http://java.sun.com/products/jndi/#download
See the README-LDAP.txt in the bundle.
It says that the javadocs for the controls are
at doc/ldapcontrols.

Hi,
I was wondering if iPlanet Server Directory 5.0 SP1 supports the Page Result
Control?
I am developing a Java Client that will read more than 2 000 entries from
iPlanet.
I have an OperationNotSupportedException with iPlanet 5.0.
Thanks in advance.
Stephane Chauvin.

Hello Stephane,
No, it is not. You can list the supported controls by executing an ldapsearch on the root DSE. 
ldapsearch -h <serverhost> -p <serverport> -s base -b "" \ "objectclass=*" supportedcontrol 
Instead of the Page Result Control, you may want to consider using the Virtual List View control (see http://search.ietf.org/internet-drafts/draft-ietf-ldapext-ldapv3-vlv-04.txt)

Is the Sun JNDI LDAP provider thread safe?

Hi,
The JNDI documentation states that the Context implementation is not required to be thread safe although some providers provide thread safety. My question is whether the Sun JNDI LDAP provider is thread safe or do we have to synchronize on the Context instance?
Thanks

Read this: http://java.sun.com/j2se/1.3/docs/api/javax/naming/Context.html
The answer, I think is no you need to synchronize accesses yourself. If you're using it from a servlet container, this should be OK, since each request is on a separate thread.

Yes, CORBA as well as the entire J2EE stack has been desupported in 9i R2.
I ran the sample using 10g database which is Java SE 4.0 compatible and therefore susceptible of acting as RMI/IIOP client. Here are the jars file i have loaded in my example
loadjava -u scott/tiger@localhost:port:instance_name -r -v
$J2EE_HOME/ejb/helloworld/dist/stub_helloworld.jar
$J2EE_HOME/lib/ejb.jar
$J2EE_HOME/ejb/helloworld/dist/helloworld-ejb.jar
$J2EE_HOME/ejb/helloworld/dist/helloworld-client.jar
[code/]
In addition, you need to:
- grant ejbclient to the schema in question
- grant java.util.PropertyPermission, java.lang.RuntimePermission, java.util.logging.LoggingPermission, and java.util.PropertyPermission
Frankly you need to read the section of my book to get everything right;
for example i tweak a bit the JNDI lookup in the client code.
Fwiw, SAP JCO callout using RMI is also covered in chapter 4 of my book.

I had a look at IndirectionValueHashtable class. It looks like the classcast is happening because the "handle-to-object" map has non String values.
Could this be a corba compatabilty issue?
The problem doesn't occur if I use weblogic initial context factory & t3 protocol.
What is the best way to overcome this problem? I dont want to distribute weblogic.jar [from 8.1.5 server]. wlclient is okay.
thanks

JNDI: Can't find Class com.sun.jndi.nis.NISCtxFactory

Hi
I searched this forum for similar problems .. and I also found some, but this questions were either not be answered or not detailed enough.
Now to my question. I've got a Java File that I imported to Oracle (I use it from PL/SQL). This Java File contains following code.
static Properties = System.getProperties();
env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.nis.NISCtxFactory");
env.put(Context.PROVIDER_URL, "nis://disney/geo.unizh.ch");
Context ctx = new InitialContext(env);
And if I run it from oracle(PL/SQL) I get the error below.
javax.naming.NoInitialContextException: Cannot instantiate class: com.sun.jndi.nis.NISCtxFactory. Root exception is java.lang.ClassNotFoundException: com/sun/jndi/nis/NISCtxFactory

The nis.jar I imported with the loadjava, so actuallay should it be in the database. But why it cant find this class (NISCtxFactory)!
I get no error if I use this code ->
NISCtxFactory test = new NISCtxFactory();
System.out.println(test);
It would be very nice if you could give me some clues. TNX!!

Hi Cyrill,
I don't know what other postings you have read, and I also don't
know why they were insufficient for you, so excuse me if I repeat
things you already know.
As far as I know, the error message you are getting is most probably
due to one of the following three causes:
1. The class is not loaded into the database.
2. The class is loaded but is not "valid".
3. You don't have permission to access the class.
To the best of my memory, there have been several posts to either
this forum or the "Products > Database > JVM" forum
http://forums.oracle.com/forums/forum.jsp?id=424322
that (in my opinion) sufficiently explain how to resolve the problem
for each of the three causes listed above.
Personally, I believe that the Oracle documentation sufficiently
explains how to resolve the above three issues, and I have posted
the URLs for the relevant Oracle documentation several times already.
I am guessing that you are trying to "talk" to an EJB (probably deployed
in SUN's application server) from a java stored procedure in the Oracle
database. If that is the case, then that question has been discussed
many times in this forum. Perhaps you can say why those discussions
were not sufficiently helpful for you.
Hope this helps.
Good Luck,
Avi.

Can anyone help? If there is someone out there with JNDI connection pool experience I would appreciate your assistance!

The issue may not be related to the number of connections or the initial
connections. Check your heap size (ms, mx). Turn on verbosegc. Your heap may
not be big enough to accept the 25,000 rows.

We are creating the result set with 25000 rows(each row has 56 columns) bygetting the connection using data source. With the initial capacity of the

the server gets out of memory exception, when we issue a new request, even

Now, if we change the initial capacity to 1 and rest all the things assame, the issue gets resolved and the server works fine.

JNDI LDAP Response Parsing Problems

Help!
I am having problems dealing with LDAP responses using JNDI 1.2.2 with the
LDAP SPI.
It seems that the detinguished name is unparsable but as far as I can see
the server output is fine. Any clues how to get around this? Have I done
something wrong or is the LDAP spi unusably buggy?
Please could you also reply in mail as this is an urgent matter for the
project I am working on. If the LDAP spi is unusable I will have to change
direction completely...
Thanks in advance,
John

at least you need cn= in front of the name.
Here some more questions you may ask yourself:
How do you know, that the requested object is in the database?
What is its DN?
Can you retrieve it using the ldap command line utilities like ldapsearch?
What does context.list("") return?

Java JNDI LDAP connectivity problem. NoSuchAttributeException

Hello,
I am trying to add a user to Active Directory server through LDAP. Following is the code I am using:
======================================================================
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://192.123.321.123:389");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "user1");
env.put(Context.SECURITY_CREDENTIALS, "user123");
try {
System.out.println("68");
Context ctx = new InitialContext(env);
System.out.println("71");
BasicAttribute oc = new BasicAttribute("objectclass", "top");
oc.add("person");
oc.add("organizationalperson");
oc.add("User");
BasicAttribute ouSet = new BasicAttribute("ou");
ouSet.add("test");
BasicAttributes attrs = new BasicAttributes(true);
attrs.put(oc);
attrs.put(ouSet);
attrs.put("cn", "ndubey001");
attrs.put("sn", "ndubey001");
attrs.put("sAMAccountName", "ndubey001");
attrs.put("givenName", "ndubey001");
attrs.put("name", "ndubey001");
ctx.bind("uid=ndubey001,ou=test,o=myserver.com", attrs);
System.out.println("74");
ctx.close();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
======================================================================
I have tried with so many different combinations. Most of the times the parameters I am passing looks okay but I keep getting the same exception as follows:
======================================================================

Can anyone tell what is the exact problem ?

Too many errors to even consider correcting your code (objectClasses, UID attribute, ctx.create)....
Refer to the following for a description & sample code:

Help with SUN JNDI tutorial example

HI guys there's an example of how to bound an object along with its codebase in the sun jndi tutorial
import javax.naming.*;
import javax.naming.directory.*;
import java.util.Hashtable;
* Demonstrates how to bind a Serializable object to a directory
* with a codebase.
* (Use Unbind to remove binding.)
* usage: java SerObjWithCodebase <codebase URL>
class SerObjWithCodebase {
public static void main(String[] args) {
 if (args.length != 1) {
 System.err.println("usage: java SerObjWithCodebase <codebase URL>");
 System.exit(-1);
 String codebase = args[0];
 // Set up environment for creating initial context
 Hashtable env = new Hashtable(11);
 env.put(Context.INITIAL_CONTEXT_FACTORY,
 "com.sun.jndi.ldap.LdapCtxFactory");
 env.put(Context.PROVIDER_URL, "ldap://localhost:389/o=JNDITutorial");
 try {
 // Create the initial context
 DirContext ctx = new InitialDirContext(env);
 // Create object to be bound
 Flower f = new Flower("rose", "pink");
 // Perform bind and specify codebase
 ctx.bind("cn=Flower", f, new BasicAttributes("javaCodebase", codebase));
 // Check that it is bound
 Flower f2 = (Flower)ctx.lookup("cn=Flower");
 System.out.println(f2);
 // Close the context when we're done
 ctx.close();
 } catch (NamingException e) {
 System.out.println("Operation failed: " + e);
So in therory you should be able to retrieve an object in through doing a look up, and then cast it... but in this approach the client that performs the look up shouldn't need to include the class definition of the object that is being retrieved, because it's being included in the code base of the context, but then how do you avoid compilation errors such:
SerObjWithCodebase.java:73: cannot resolve symbol
symbol : class Flower
location: class SerObjWithCodebase
Flower f2 = (Flower)ctx.lookup("cn=Flower");
in the client code that is attepting to perform the look up?... is there a work-around for this problem? please let me know, thanks in advance.

As far as I am aware, there is no possible way to compile or execute code without the client knowing it's definition.
The client will always need the class definition if it want's to use it.
If you don't want this coupling, then you could look at using an EJB container (which still requires the client to have skeleton code) or using something like web services
