Javax.naming.Reference
Hi all,
I have deployed an EJB module in PI 7.1, but when i am checking in netweaver administrators -> "problem monitor" -> JNDI browser, it is coming as <JNDI NAME> -> class Name: javax.naming.Reference. What can be the cause of this error.
Please help if possible! Thanks!

hi Volker,
How to check audit log entries using NWA (for trace).
I had used module correctly in communication channel i.e. localejbs/<JNDI Name>. But when i am executing the scenario, i am getting following error from RWB:

SOAP to SOAP call - javax.naming.Reference error - PI 7.1
Hi friends,
In our SOAP to SOAP scenario (synchronous) , we are getting the below error in SXMB_MONI.
Error:
com.sap.engine.interfaces.messaging.api.exception.MessagingException: SOAP: response message contains an error XIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: java.lang.Exception: #Begin#Exception occurred while the JNDI NamingManager was processing a javax.naming.Reference object.#End#
We have not used any custom module. In both sender & receiver CC only SAP standard module is there. Also there is no interface mapping in Interface Determination step.
We are not getting this error for all messages. But, some of the messages we are getting this error.
Kindly clarify friends.
Kind regards,
Jegathees P.Hi,
Thanks for your reply!!
My Scenario is File to SOAP to File.
Configred modules in Sender channal below:
Prcessing sequence:
Number Module Name Module Key
1.......... AF_Modules/RequestResponseBean.......1
2.......... CallSapAdapter..........................................2
3.......... AF_Modules/ResponseOnewayBean.......3
Module Configuration:
Module Key Parameter Name ParameterValue
1 passThrough true

Java.lang.ClassCastException: javax.naming.Reference
Hi All,
I bound a JMS topic and connection factory into the SUN file system JNDI.
When I tried to look them up I received the execption in the subject. What does that mean? Thanks All!
Context ctx = getInitialContext();
TopicConnectionFactory factory = (TopicConnectionFactory)
ctx.lookup(factoryName);
Topic topic = (Topic)ctx.lookup(topicName);
public static Context getInitialContext() throws NamingException {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.fscontext.RefFSContextFactory");
p.put(Context.PROVIDER_URL, url);
if (user != null) {
p.put(Context.SECURITY_PRINCIPAL, user);
if (password == null)
password = "";
p.put(Context.SECURITY_CREDENTIALS, password);
return new InitialContext(p);Hi,
I think that it possibly means that the JMS object that
you look up is not that class that you want. I think that
you should check your configuration of the server. Or
ttry not to use reference method. if the look up procedure
can be successful, you may try to reference method then.
Or you may dump the object information to see which object
is looked up .
good luck,

EJB Reference could not be resolved (javax.naming.NameNotFoundException)
I am new to EJBs and am trying to get a simple Java client to run which I've generated from a EJB3.0 session bean.
The code for the client (LoanAppFacadeClient.java) is
package buslogic;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
public class LoanAppFacadeClient {
public static void main(String [] args) {
try {
final Context context = getInitialContext();
LoanAppFacade loanAppFacade = (LoanAppFacade)context.lookup("java:comp/env/ejb/LoanAppFacade");
// Call any of the Remote methods below to access the EJB
// System.out.println( loanAppFacade.getLoans( ) );
loanAppFacade.addLoan( "Galactic Loans", 30, "fixed", 6.25 );
String ssn = "123-12-1234";
System.out.println(loanAppFacade.getCreditRating( ssn ));
} catch (Exception ex) {
ex.printStackTrace();
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
// Standalone OC4J connection details
env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.naming.ApplicationClientInitialContextFactory" );
env.put( Context.SECURITY_PRINCIPAL, "oc4jadmin" );
env.put( Context.SECURITY_CREDENTIALS, "welcome1" );
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/LoanApp");
return new InitialContext( env );
When the trying to run the client I get a warning:
"WARNING: EJB Reference "ejb/LoanAppFacade" could not be resolved."
followed by the error
"javax.naming.NameNotFoundException: java:comp/env/ejb/LoanAppFacade not found in Lab1_BusinessServices-app-client"
When the client was created I right-clicked on the session bean (LoanAppFacadeBean which implements LoanAppFacade) and chose New Sample Java Client.
This automatically creates the java client and also created the following xml file (application-client.xml)
<?xml version = '1.0' encoding = 'windows-1252'?>
<application-client xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application-client_1_4.xsd" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee">

<ejb-ref-type>Session</ejb-ref-type>

Could someone please help me to fix these errors?
Thanks,
AndrewI used windows for years whereby I stored all photos in folders. As macs don't use this concept I am finding it hard to organize my photos.
You can do this on your Mac too. Just don't use iPhoto. But iPhoto is a lot more flexible.
For instance:
I usually sort them by month so when I say move to an album I mean I create an album called for example '2013 March' so I can easily find specific photos/videos.
Click on the Magnifying Glass lower left to reveal the search box. Then click on the magnifying glass in the search box, and select Date. Now you can instantly find all the photos from a particular month, or day.
File -> New Smart Album will allow you to create an automatic album for any date or date range you choose.
Select one of the affected videos in the iPhoto Window and go File -> Reveal in Finder -> Original. A Finder Window should open with the file selected. Does it play? -

Mari.Hi,
My Client Program is as follows:
import javax.ejb.*;
public class Client{
public static void main(String[] args){
Account account = null;
try{
Context = new
Context = new
InitialContext(System.getProperties());
AccountHome home = (AccountHome)
AccountHome)
ctx.lookup("java:comp/env/ejb/AccountBean");
home.create("123-456-7890","John");
}catch(...){
}What are the System Properties? Are you running the client remotely? Are you running the client as a stand alone Java app or using the Weblogic's Client Runner? 'java:comp' as the jndi name is usually used when the client runs inside the container... But it doesn't seem to be the case.

<ejb-ref>
<ejb-ref-name>SeguridadService</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<remote>penoles.infraestructura.business.services.seguridad.SeguridadService</remote>
<ejb-link>SeguridadService</ejb-link>
</ejb-ref>
And change the applicationContext.xml
<bean id="gruposUnidadesServiceFacade" class = "org.springframework.jndi.JndiObjectFactoryBean">
<property name="resourceRef" value="true"/>
<property name="proxyInterface" value="penoles.infraestructura.web.servicesfacades.gruposunidades.GruposUnidadesServiceFacade"/>
<property name = "jndiName" value = "GruposUnidadesService"/>
</bean>

Javax.naming.NameNotFoundException: error in whil calling EJB Bean
Dear friends,
I have created (Bean Managed Entity) a remote,home and bean objects for adding a country in a database. When i convert
into jar and and deploy means, its working fine. But if i put into a package means it does work
and raise "javax.naming.NameNotFoundException" error.
i keep my files as following folder structure

Who knows the solutions for my problem
Thanks for advanceCould be that your EJB is connected to a wrong datasource called only "jdbc"?
Strangely you say that while reading data all works fine (so the datasource definition is ok) but only when writing data there is a NamingException.
The stacktrace seems to report an error while getting datasource reference inside com.soluzionasf.arqw10.gc.cmp.OracleSequenceSessionLocal.getNextSequenceNumber method, the problems seems to be a bad name resource name ("jdbc" instead of java:jdbc/OracleDS or java:comp/env/jdbc/OracleDS if you use resource reference in your web.xml file). If you created this class as a CMP perhaps you misstype the right datasource name, otherwise if you code this method by yourseft you misstype the naming reference. -
Error in EJB client program (javax.naming.NoInitialContextException)
Hi folks ,
I'm new to j2ee programming and using Netbeans 5.5 , i created a session bean program and deployed successfully in JOnAS application server but i'm not able to run the client program which invokes session bean (EJB module ).
when i run client program i'm getting the following error .
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:645)

at javax.naming.InitialContext.lookup(InitialContext.java:351)
at SimpleSessionClient.Main.main(Main.java:33)
BUILD SUCCESSFUL (total time: 21 seconds)
but the same program runnig perfectly when i deploy in Java System Application Server(8.2(JSAS))
I included j2ee.jar and appserv-rt jar in classpath of client program for JSAS i don't know what are the jar files (which does the same function as j2ee.ar,appserv-rt.jar ) which is to be included for JOnAS .
i'm struggling with this for the past two weeks . please tell me the solution .
Thanks in advanceThanks for the suggestion artntek.
I located the jndi.properties file in the %J2EE_HOME%\lib\classes folder, and I copied it to the %J2EE_HOME%\bin directory, but nothing seems to have changed.
does anyone know what value should be associated with Context.INITIAL_CONTEXT_FACTORY in the properties for the InitialContext object? More specifically, what value should be used for the reference install of the 1.3 j2ee release from sun?
This error suggests to me that a class name must be specified for the initial naming context factory - but I don't know what to use. -
Javax.naming.AuthenticationException: No such domain/application:

Anyone knows what's the cause of this error? I follow exactly the steps in Jdeveloper 11g tutorial. The only difference is that my database is MS SQL database.Same error.
The real application (web and ejb's) are running on the same OC4J instance. The Web client are accessing the ejb's on port 3101, so i think this is the correct rmi port.
The server is a part of an infrastructure that are running on the same server, the server is one of two ApplicationServers that the infrastructure (farm) is controlling.
each server has an instance name, the server i was deplying to has name instance2. Maybe i have to give a reference to to the instance? -
Javax.naming.LinkException JNDI error Help please
Hello All,
I am trying my first bean on Weblogic 7 and can't seem to get the deployment descriptor correct. The home
interface is, ObjectIDLocalHome and the full class name is com.oga.gserve.biz.oid.ObjectIDLocalHome. I am
using the fully qualified class name so that I can do an EJBHomeFactory latter on.
I have used the WLS console and see my bean in the JNDI tree I also used the following to find it:
public static void loop(final Context ctx, final String name) throws Exception {
try {
String local;
NamingEnumeration childrenOfNaming = ctx.list(name);
while (childrenOfNaming.hasMore()) {
NameClassPair ncPair = (NameClassPair) childrenOfNaming.next();
System.out.print(ncPair.getName() + " (type ");
System.out.println(ncPair.getClassName() + ")");
if (name.length() > 0) {
local = name + "." + ncPair.getName();
} else {
local = ncPair.getName();
loop(ctx, local);
} catch (javax.naming.CannotProceedException e) {
// We are at a leaf, no more children.
I find ObjectIDLocalHome as type javax.naming.LinkRef, as a leaf of com.oga.gserve.biz.oid
So I know it exist!
But why as a javax.naming.LinkRef?
Now when I try the following:
String cName = ObjectIDLocalHome.class.getName();
ObjectIDLocalHome home = (ObjectIDLocalHome) ctx.lookup(cName);
I get:
javax.naming.LinkException: . Root exception is javax.naming.NameNotFoundException: Unable to resolve
'java:app.ejb/gs-ejbs.jar#ObjectID/local-home' Resolved: '' Unresolved:'java:app' ; remaining name
'java:app.ejb/gs-ejbs.jar#ObjectID/local-home'
What is wrong?
It must be in one of the .xmls but I can't see it:

Javax.naming.LinkException Please Help
Hello All,
I am trying my first bean on Weblogic 7 and can't seem to get the deployment descriptor correct. The home
interface is, ObjectIDLocalHome and the full class name is com.oga.gserve.biz.oid.ObjectIDLocalHome. I am
using the fully qualified class name so that I can do an EJBHomeFactory latter on.
I have used the WLS console and see my bean in the JNDI tree I also used the following to find it:
public static void loop(final Context ctx, final String name) throws Exception {
try {
String local;
NamingEnumeration childrenOfNaming = ctx.list(name);
while (childrenOfNaming.hasMore()) {
NameClassPair ncPair = (NameClassPair) childrenOfNaming.next();
System.out.print(ncPair.getName() + " (type ");
System.out.println(ncPair.getClassName() + ")");
if (name.length() > 0) {
local = name + "." + ncPair.getName();
} else {
local = ncPair.getName();
loop(ctx, local);
} catch (javax.naming.CannotProceedException e) {
// We are at a leaf, no more children.
I find ObjectIDLocalHome as type javax.naming.LinkRef, as a leaf of com.oga.gserve.biz.oid
So I know it exist!
But why as a javax.naming.LinkRef?
Now when I try the following:
String cName = ObjectIDLocalHome.class.getName();
ObjectIDLocalHome home = (ObjectIDLocalHome) ctx.lookup(cName);
I get:
javax.naming.LinkException: . Root exception is javax.naming.NameNotFoundException: Unable to
resolve 'java:app.ejb/gs-ejbs.jar#ObjectID/local-home' Resolved: '' Unresolved:'java:app' ; remaining
name 'java:app.ejb/gs-ejbs.jar#ObjectID/local-home'
What is wrong?
It must be in one of the .xmls but I can't see it:

Bradyou must pack all .java into one package ,even the client,
then you can use it normally.

EJB Local Interfaces / javax.naming.NamingException

I have tried to deploy a very simple (Hello World like)EJB-Application. It contains a simple stateless SessionBean (with local interfaces) and a JSP which is using the EJB.
Opening the JSP i get the following error message:

Java.io.NotSerializableException: javax.naming.InitialContext
I am using Workshop to create a Stateful session bean and i just have a simple member variable in the bean of type string. I didnt override the ejbCreate and setSessionContext methods and i get the following error when it is trying to passivate the bean.

The stack trace sesms to tell me that it is something internal to the workshop generated EJBHome class since i do not see any reference to InitialContext in my bean class.
Is it some bug with workshop. Or is it something wrong i am doing.
Thanks
sriramPage 325 (paragraph 5) of O”Reilly Enterprise Java Beans (4th Edition) states:
“During the lifetime of a stateful session bean, there may be periods of inactivity when the bean instance is not servcing mentod from the client. To conseve resources, the container can passivate the bean instance by preserving its conversation state and evicitin the bean instance from memory. A ben’s convesatin stat may consist of primitive values, object that are serializable, and the following special types:
javax.ejb.SessionContext
javax.ejb EJBHome
javax.ejb EJNObject
javax.ejb Jta.UserTRansaction
javax.ejb Naming.Context(only when it references the JNDI ENC)

Handlling exception: javax.naming.PartialResultException: Unprocessed Conti
I am running the following Java Code (in an agent in Lotus Notes, hence some of the odd bits). I've searched long and hard. I know I'm getting my error because I am searching the from the base DN in AD.
It also appears you can't get around this with referrals settings as AD doesn't support them. I having trouble with the whole global catalog thing too.
However, my code is working and returning the field I need. I would like to handle the error and get on with things.
Now I am not a java programmer. Is it possible to handle the error and return to the code that generated it, or am I finished with the 'try' stuff as soon as my first exception is thrown?
Sorry if this is a stupid question.

Is there a way maybe via logging or SNMP query, to find out what song is being played on airtunes? I checked out the airport MIB file on the doc site and have logging set to debug, but no luck.
