RMI JNDI Lookup in ServletContextListener
Hi,
I am attempting to do a JNDI lookup (using the RMIInitialContextFactory) of a session EJB inside a ServletContextListener. But when I do I get an exception saying it cannot find the name I lookup. If I set rmi.debug to true I can see that a 'SocketException: Socket closed' is caught internally. I can also see from the RMI debug that the attempt to load the EJB interface class fails because it is trying to use the application server's classloader and not the web applications classloader. If I put the JAR containing the interface class into the applib directory none of the above occurs.
Should I be able to do the JNDI lookup within the SerlvetContextListener? Is this a bug?
Cheers,
Rich.
This exception only appears once I turn rmi.debug on. Like I said previously if I put the EJB interfaces JAR into applib it does not occur.

RMI JNDI Lookup on remote iAS causing "Not Authorised"
Hi all
I'm running through an OJMS example using AQ and all is looking good until I try and Update my plan from Design Studio..
I get:
IMessageSourceReceiver->messageReceive: javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException: Not authorized; nested exception is:
javax.naming.AuthenticationException: Not authorized. Root exception is javax.naming.AuthenticationException: Not authorized

This appears to be because iAS is using JAZN security and is not allowing an anonymous lookup from BAM.
I can't see anywhere in Architect or Administrator where I can configure a username/password for authentication with my iAS install...
Has anyone any advice?
Cheers
ChrisHi, Chriseb2
even i also have the same problem
I am getting one Error while Creating Enterprise Link Plan in Design Studio of BAM and Failed to Create the Plan.

RMI-IIOP JNDI lookup returns com.sun.corba.se.internal.iiop.CDRInputStream
I have two different RMI-IIOP java clients, one is working fine and the other is not. Both are using weblogic.jndi.WLInitialContextFactory from wlclient.jar in WLS 8.1sp5 and JDK 1.4.2_6.
One java client is a straight-forward java main. JNDI lookup is returning EJBHome_Stub correctly loaded by sun.rmi.server.LoaderHandler$Loader
The other java client is a complex java program with multiple threads and many jars. A thread does the same JNDI lookup as the simple java client, but the object returned is of type com.sun.corba.se.internal.iiop.CDRInputStream_1_0$1 which has NULL classloader (bootstrap classloader).
What condition triggered the WebLogic InitialContext to default to com.sun.corba.se.internal.iiop.CDRInputStream?Kevin Fung <> writes:
This is usally symptomatic of an IOR without the corresponding stub
being loaded, usually because the correct security manager is not
set. However the client jar bypasses the security manager to try and
avoid this problem, so I am confused as to why you are seeing this. Do
you know which object it is accessing? Can you try putting IIOP stubs
for it in the client?

EJB 3.0 and jndi lookup (simple question)
hi all,
i am newbie on Weblogic Application Server and i have some issues,
i have weblogic application server 10.0, also i have oracle timesten in-memory database, i have configured datasource and deploy my ejb 3.0 application, but i could not done jndi lookup?
here is my example:
1. one stateless session bean :
import javax.ejb.Remote;
@Remote
public interface InsertSubscriber {
public void insertSubscriber(SubscriberT subscriberT);
} 2. here is it's implementation :
@Remote(InsertSubscriber.class)
@Stateless
public class InsertSubscriberBean implements InsertSubscriber {
@PersistenceContext(unitName = "TimesTenDS")
private EntityManager oracleManager;
public void insertSubscriber(SubscriberT subscriber)
try {
System.out.println("started");
oracleManager.persist(subscriber);
System.out.println("end");
} catch (Exception e) {
e.printStackTrace();
}3 and my test client :
public class Client {
public static void main(String[] args) {
Context ctx = null;
Hashtable ht = new Hashtable();
ht.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, "t3://192.9.200.222:7001");
try {
ctx = new InitialContext(ht);
InsertSubscriber usagefasade = (InsertSubscriber) ctx
.lookup("ejb.InsertSubscriberBean");
} catch (NamingException e) {
e.printStackTrace();
} finally {
try {
ctx.close();
} catch (Exception e) {
e.printStackTrace();
}what i did incorrect ???
i got error like this : Name not fount exception
when i tried to view jndi tree on weblogic server application console i found this :
Binding Name:
TimestenExampleTimestenExample_jarInsertSubscriberBean_InsertSubscriber
Class:
test.InsertSubscriberBean_o7jk9u_InsertSubscriberImpl_1000_WLStub
Hash Code:
286
toString Results:
weblogic.rmi.internal.CollocatedRemoteRef - hostID: '2929168367193491522S::billing_domain:AdminServer', oid: '286', channel: 'null'what does it mean how i can done lookup to jndi ?

Georgia.Hi All,
I am using the weblogic cluster with session replication and EJB 2.0 with Local entity beans.
for fail-over session should be replicated to another server so we can achive the same session if 1st server fails.
Suppose i m using two managed server(server1,server2) in the cluster.I am storing the object of class ABC into session and object contains the instance of Local-EntityBean home but i put that as a transient.I have also override the readObject and write object method.
when write object is called on 1st server,readObject method should be called on second server so we will be sure that session is replicating properly.
pleaase find the code below : -
public IssuerPageBean() {
initEJB();
private void readObject(java.io.ObjectInputStream stream) throws IOException, ClassNotFoundException {
stream.defaultReadObject();
initEJB();
initializeCommonObject();
private void writeObject(java.io.ObjectOutputStream stream) throws IOException {
stream.defaultWriteObject();
private void initEJB() {
try {
ic = new InitialContext();
issuerHome = (LocalIssuerHome) ic.lookup("java:comp/env/Issuer");
} catch (NamingException e) {
e.printStackTrace();
in my case if i am calling the constructor IssuerPageBean(),it calls the initEJB() method and lookeup the entity local home properly but when readObject method is called on another server only initEJB() method is called directly and getting the exception below :

Looking for tips on a OC4J/JNDI lookup problem
Hello All,
I am running into a situation where a user I have setup in Oracle Enterprise Manager 10G Instance Level Security is not able to access our JNDI resources. We have tried providing all the roles(including administrators) to this user, but to no success. For some reason it works in standalone though.
Our exception is fired when deploying the application and the spring configuration tells the app to fetch the jms connection factory from JNDI.
Caused by: javax.naming.NoPermissionException: Not allowed to look up jms/ConnectionFactory, check the namespace-access tag setting in orion-application.xml for details

I wonder if there is a specific role that OC4J is looking for to allow the app to use JNDI? One thread I read earlier mentioned granting the user RMI permission. Any tips on where this could be configured?
Our namespace section of the orion application xml file is below...
<namespace-access>
<read-access>
<namespace-resource root="">
<security-role-mapping name="<jndi-user-role>">
<group name="administrators" />
</security-role-mapping>
</namespace-resource>
</read-access>
<write-access>
<namespace-resource root="">
<security-role-mapping name="<jndi-user-role>">
<group name="administrators" />
</security-role-mapping>
</namespace-resource>
</write-access>
</namespace-access>
Any thoughts or recommendations for isolating and troubleshooting the problem would be highly appreciated.
Many Thanks in Advance Guys!What Mylenium said. Although, perhaps with Forge Freeform and a huge amount of work, you might be able to fake it.

Is it that the JNDI lookup failed when one of my beans tried to do a lookup on 'ejb/TEDIObjectManagerLocal'? I believe there's some configuration that went wrong (EJB reference binding or something) when I deployed the EAR. The reason I don't think it's a faulty code is because the EAR runs like a charm when I deploy it on Oracle 10g and Weblogic.
I am really stuck on this problem and shall appreciate any help that I can get. I can send the code, xdoclet tags and configuration if that might assist someone.
Thanks

- I only see the namespace entries for my Session beans. There's one
entity bean also which does not show up.
- I don't see anything for the Local Home interfaces, it shows only the
Home interfaces.
As additional information, I'm looking up 'TEDIObjectManagerLocal'
using 'ejb/TEDIObjectManagerLocal'. I also tried using 'local:ejb/ejb/TEDIObjectManagerLocal' (as Karthyk suggested) and
'java:comp/env/ejb/TEDIObjectManagerLocal', but that does not work
either.
Also, the XDoclet tags that I use to generate the interfaces for
TEDIObjectManager bean are as follows:

NOTE: When deploying on WAS, in the 'Map EJB references to beans' step, I'm giving the following values for 'TransformationEngine' bean:
Reference binding: ejb/TEDIObjectManagerLocal
JNDI Name: ejb/tedi/TEDIObjectManager
There's one other similar binding that works for 'TEDIObjectManager'
bean:
Reference binding: ejb/TEDIObjectLocal
JNDI Name: ejb/TEDIObject
Everything in ejb-jar and ibm-ejb-jar-bnd.xmi look similar for this working bean, there is one difference though, I do the lookup on this one using 'java:comp/env/ejb/TEDIObjectLocal', but I've already tried that for the other one.
Really appreciate your time.
Thanks

Weblogic JNDI lookup in Applet
Hi
We are facing problem in JNDI lookup inside the applet
here is the scenario
We have two weblogic servers(port 7001)
one server is main server where the Applet1 , weblogic.jar and app.htm
are in C:\bea\wlserver6.0sp1\config\mydomain\applications\DefaultWebApp_myserver
and another is proxy server where HTTPProxyServlet is running and one
web.xml file ( wall these files are provided by weblogic and the port
of proxy server is 448)
Both the servers are running on different machines
and when we run the client browser and put the folloing url
http://proxyServer IP Address:448/app.htm
we get the following exception

any clue or thought. please help

mohanIt looks like the object that you have placed into the JNDO tree is not serializable or doesnt implement exernalizable!

Stand-alone JNDI lookup of an EJB in an Enterprise Application (EAR) build
Hi All,
I am having some difficulty doing JNDI look up an EJB 3.0 Bean that is part of an Enterprise Application (EAR) build. Below are all the related codes:
package ejb;
import javax.ejb.Local;
@Local
public interface Hello1Local {
public String getHello1();
package ejb;
import javax.ejb.Stateless;
@Stateless
public class Hello1Bean implements Hello1Local {
public String getHello1() {
return "I am Hello1 Bean!";
package ejb;
import javax.ejb.Remote;
@Remote
public interface Hello2Remote {
public String getHello2();
package ejb;
import javax.ejb.Stateless;
import javax.ejb.EJB;
@Stateless
@EJB(name="ejb/Hello1",
beanInterface=Hello1Local.class,
beanName="Hello1Bean")
public class Hello2Bean implements Hello2Remote {
@EJB private Hello1Local hello1bean;
public String getHello2() {
return hello1bean.getHello1();
There is no problem looking up Hello2 Bean using an Application Client such as the following:
public class LocalHelloApplicationClient {
@EJB(name="Hello2")
private static Hello2Remote hello2Bean;
public static void main(String[] args) {
System.out.println("hello2Bean.getHello2(): " + hello2Bean.getHello2());
}There is also no problem doing JNDI lookup (from a Stand-Alone Client the same bean if both Hello1 and Hello2 were created by themselves. ie not part of an Enterprise Application (EAR) build. However, I am wondering whether it is possible to do JNDI lookup of the same bean (Hello2) that is part of an Enterprise Application (EAR) built. Below are the type of JNDI lookup entries that I have tried without success:
public class StandalonePojoCallHelloWorld {
public static void main(String [] args)
try
InitialContext jndiContext = new InitialContext();
Hello2Remote hello2Bean = (Hello2Remote) jndiContext.lookup("ejb.Hello2Remote");
or
Hello2Remote hello2Bean = (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.Hello2.remote");
or
Hello2Remote hello2Bean = (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.ejb.Hello2Remote");
or
Hello2Remote hello2Bean = (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.Hello2Remote");
or
Hello2Remote hello2Bean = (Hello2Remote) jndiContext.lookup("LocalHelloEnterpriseApplication.LocalHelloEnterpriseApplication-ejb.Hello2Remote");
System.out.println("hello2Bean.getHello2(): " + hello2Bean.getHello2());
catch (javax.naming.NamingException ne)
ne.printStackTrace();
They all came up with the same error message:
javax.naming.NameNotFoundException: LocalHelloEnterpriseApplication.LocalHelloEnterpriseApplication-ejb.Hello2Remote not found

I've somme problems to get access to ejb interface from remote stand-alone client.
Here is my EJB code :
package stateless;
import javax.ejb.Stateless;
@Stateless(name = "TestSB", mappedName = "ejb/stateless/TestSB")
public class TestEJBBean implements TestEJBRemote {
public String getMessage() {
return "Hello EJB World";
}And the remote interface :
package stateless;
import javax.ejb.Remote;
@Remote
public interface TestEJBRemote {
String getMessage();
} In client side, i just edit main.java like this :
package testclient;
import java.io.FileInputStream;
import java.util.Properties;
import javax.naming.InitialContext;
import stateless.TestEJBRemote;
public class Main {
public static void main(String[] args) throws Exception {
Properties props = new Properties();
props.load(new FileInputStream("jndi.properties"));
InitialContext ctx = new InitialContext(props);
TestEJBRemote testEJB = (TestEJBRemote) ctx.lookup("ejb/stateless/TestSB");
System.out.println(testEJB.getMessage());
}here is my jndi.properties file (my glassfish server IP is 192.168.0.10) :
java.naming.factory.initial = com.sun.enterprise.naming.SerialInitContextFactory
java.naming.factory.url.pkgs = com.sun.enterprise.naming
java.naming.factory.state = com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl
org.omg.CORBA.ORBInitialHost = 192.168.0.10
org.omg.CORBA.ORBInitialPort = 3918when i run client on the same machine than the glassfish app server, it works fine.
But i run it on the different machine than the glassfish app server (on the same LAN without firewall), it fails with this error message :

Doing a jndi lookup() for an EJB deployed on Glassfish v3
Hello.
I have deployed a Stateful Sesion EJB on a Glassfish v3 AppServer.
It is running under 'localhost' on my laptop pc.
I am also running a stand-alone java application on the same pc... it attempts to get a remote connection from the client-app to the Glassfish Server and then do a jndi lookup() to get a reference to my EJB.
here is the client source code:
public class LookupTest {
static Properties props = null;
public static void main(String[] args) {
try {
props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
props.put(Context.PROVIDER_URL, "iiop://localhost:3700");
Context ctx = new InitialContext(props);
System.out.println( "the context is: " + ctx);
System.out.println( "the environment contains: " + ctx.getEnvironment() );
System.out.println( " ");
// do a lookup.
Object elementObj = ctx.lookup("SerialContextProvider");
System.out.println(elementObj);
} catch (NamingException e) {
e.printStackTrace();
When I run this app, there are no Errors or Exceptions. It appears that the connection succeeds. But there are no EJB references in the context that is created. The only item that seems to be present in the context is an item named "SerialContextProvider", as noted in the return value from a list("") method invocation. Why can i not see the EJB within the context? Is my code wrong ??
Thanks,
Andy Jerpe
Edited by: user1169567 on Nov 28, 2010 12:12 PMOk, but the communication seems to be OK over the wire because if I use netstat -a I can see the ESTABLISHED connection with the server in the right RMI port.
TCP PORTAL35:1581 caapiranga:12405 ESTABLISHED
and then when I stop the instance in the OAS, the client shows an exception telling that the connection was lost.
An curious thing is that the ons.log doesn't log this connection ;/ -
Objects returned via JNDI Lookup
All,
I have had this nagging question in my head about JNDI lookups for some time
now, but haven't had the time to do the proper research. The question is
simple.
The setup is simple as well. Suppose that we have a typical WLS setup, with
WLS running in a JVM on a server host somewhere, with objects bound to its
JNDI tree (we'll leave clustering out of the picture for simplicity's sake),
and we also have a WLS client Java application. The client connects to WLS
and performs various JNDI lookups on the server. Some of these objects
implement java.io.Serializable, some do not.
The question is, if the client uses JNDI to lookup an object that exsts in a
separate JVM, and that object does not implement Serializable, how does this
object come to be instantiated on the client?
This leads to a second question: What exactly is getting returned from a
JNDI lookup? A reference to an object or a copy of it? I can see that
lookups within a single JVM would return a reference, but the cross-JVM
lookup is less clear to me.
Any and all help appreciated,
-jcThis leads to a second question: What exactly is getting returned from a
JNDI lookup?From how I understand it, only Serializable objects are returned such as RMI
stubs, which serve as proxies to EJB or other RMI servers registered in JNDI.

Below, are the JNDI settings I am using. The application by the name mindejb was deployed and is accessible using server side JSP or servlets. When I use a stand alone OC4J, the same settings (different port) work fine!
java.naming.factory.initial=com.evermind.server.rmi.RMIInitialContextFactory
java.naming.provider.url=ormi://localhost:3101/mindejb
java.naming.security.principal=admin
java.naming.security.credentials=admin
Thanks,
AviWhen you are running within an Oracle Application Server managed OC4J environment, then you should use the OPMN protocol loader we have that will insulate you from the specified ORMI port being used by OC4J.
The OPMN port is fixed so you can always rely on it, whereas the specific ORMI port used by an OC4J instance changes depending on the startup sequence, the number of procs configured, etc.
Here's a piece from the EJB documentation
http://download-west.oracle.com/docs/cd/B14099_19/web.1012/b15505/access.htm#i1019709
Location
All ports, including the RMI port, are dynamically set by OPMN when each OC4J instance starts. When you specify the following URL in the client JNDI properties, the client-side OC4J retrieves the dynamic ports for the instance, and chooses one from the list for communication.
java.naming.provider.url= opmn:ormi://<opmn_host>:<opmn_port>:<oc4j_instance>/<application-name>
The OPMN host name and port number is retrieved from the opmn.xml file. In most cases, OPMN is located on the same machine as the OC4J instance. However, you must specify the host name in case it is located on another machine. The OPMN port number is optional; if excluded, the default is port 6003. The OPMN port is specified in opmn.xml.

JNDI Lookup failing in specific instances
Hi All
We have an application deployed to OC4J 9.0.4.1 - the application consists of a collection of local/remote session beans and nearly 100 entity beans.
We are calling a local session bean and local entity bean from a remote SB. Now in most cases our JNDI lookups work fine, however some specific ones do not.
The following are our JNDI specific properties :
"jndiproviderclass"
com.evermind.server.rmi.RMIInitialContextFactory</property"url"
ormi://HOSTNAME:23792/Twe
"security_principal"
admin
"security_credentials"
welcome
If anyone has any ideas why some specific deployments would not work, I can provide more details.
ThanksHi Jon,
I got it working a couple of days ago. First I tried manually but could not get it working, then I found this description of how to do it using the Enterprise Manager and then it worked. Check: http://download-uk.oracle.com/docs/cd/B31017_01/integrate.1013/b28994/adptr_db.htm#BDCFIEDJ
I defined a connection pool, a datasource and connection factory. In 6 step you should use a DbAdapter instead of an AppsAdapter, and don't put anything in dataSourceName. I choose No Connection Pool for the connection factory.

ClassCastException on ejb jndi lookup
Hello,
I try to get an standalone remote client to to connect to my stateless session bean:
java.util.Properties props = new java.util.Properties();
props.put("java.naming.provider.url", "181.205.12.19:50004");
props.put("java.naming.factory.initial", "com.sap.engine.services.jndi.InitialContextFactoryImpl" );
props.put("java.naming.security.authentication", "simple");
props.put("java.naming.security.principal", "j2ee_admin");
props.put("java.naming.security.credentials", "*****");
jndiContext = new InitialContext(props);
fetching of jndi context is fine, but once I try to lookup my home interface I get a class cast exception:
home = (ToEdifactConverterHome) PortableRemoteObject.narrow(jndiContext.lookup ("sap.com/EdifactEar/ToEdifactConverterBean"), ToEdifactConverterHome.class);
java.lang.ClassCastException
at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:293)

at test.cceag.transform.TransformTester.setUp(TransformTester.java:74)
at test.cceag.transform.TransformTester.main(TransformTester.java:48)
The jndi lookup seems to return the bean implementation object, but not the home interface itself.
Thanks for any hints
MatthiasHi Matthias,
i think the guide
"How to...EJB: Accessing EJB Applications Using JNDI"
will help you to solve the ejb lookup problem:
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/0736159e-0301-0010-9ea4-c63d83d0797b
good luck, Katharina -
NamingException on EJB jndi lookup
I have two applications - deployed under the "default instance".
When I start up OC4J and deloy app1 and app2, then app1 can do a JNDI lookup on a session bean that resides in App2. It uses the RMIInitialContextFactory.
Provider is "ormi://localhost/app2"
My problem is that if I undeploy and redeploy app2, then app1 suddenly can't do a lookup to any sessionBean found in app2 anymore, even though the jndi name still shows up in the browser, and if I try to look it up from an external application running outside of oc4j (with exactly the same code as I'm using in app1), it also works.
So why is app1 not able to find app2 via jndi after a redeployment?
DAvi - thank you for your response.
First of all, I run on Suse Linux 10.1. Dunno if that's any help, but hey, more info can't help :)
Let's answer your questions:
1.) OCJ4 Version: 10.1.3.0.0 (build 060119.1546.05277)
2.) JDK Version: 1.5.0_07-b03
As for your suggestions:
1.) app1 = parent of app2.
I'm rather new to Oracle, so maybe I made a mistake during my investigations. Still, I'd like to give a breakdown: I built a framework-type application, and thought about deploying "child modules" (plug-in applications) underneath it, as you proposed.
This worked fine, but there comes a problem whenever you try to use something like Hibernate in any application that's not deployed in the root (ie any app that's deployed as a child of another). The problem came in 2 flavours:
A) If you use a jar in the parent and try to do resource loading from the child, the context of the parent is used the whole time. Since the search-policy of the class-loader is loaded->parent->shared->local, and if Hibernate is already used in the parent, it never gets to the child and thus trying to load a resource in the child is futile since parent can't see child context.
B) Lets say you're not using Hibernate at all in the parent application. When doing resource loading (eg the hibernate.cfg.xml file), Hibernate tries to locate the resource via Thread.currentThread().getContextClassLoader(). OC4J returns the parent-app's thread as the currentThread, NOT that of the child-application that you're actually running the code from, thus it will never be able to pick up resources from within a jar part of the child application. The only way that I managed to get it to work, was to include the Hibernate3.jar as part of the EAR deployment (ie listed it as <library path...> in the orion-application.xml. Putting it in shared-libs or app-libs didn't work...ever. Also, if I happened to use Hibernate in the parent-application, it doesn't matter if I put hibernate3.jar in the EAR of the child - the parent-version gets picked up and used due to the search-policy... NOTE: This is in a JAR - I'm not using WAR's so cannot force local loading as is possible with web-apps...
I then opted to deploy applications seperately under the root, and using RMI to communicate from the framework-application to its "modules", and vice-versa. The master doesn't know the exact type of the remote interface of whatever child-module it needs to call, so it uses reflection to call the "create" on the EJBHome of whatever child-module it needs to invoke as well as the method on the actual remote-interface.
Please note, if I deploy both applications (master and child), and perform JNDI lookups from master to child, it works perfectly. As soon as I do a redeploy (or explicity undeploy, deploy), JNDI fails. External clients, though, works all the time. Also, if I redeploy the child before ever calling it from the parent-application, it also works after I did redeployment. It's as if, when you do a JNDI lookup the first time, it caches something and from there on it breaks if you do a redeploy and perform a consequent app-to-app JNDI lookup...
2.) dedicated.rmicontext=true
I tried this by setting it as a JNDI property before getting the InitialContext - makes no difference, unfortunately.
//========CODE============================
// This is in a SessionBean inside the Master Application. For the time being I've hard-coded the provider-url of the client-application.
// NOTE: This EXACT same code is used in the external java client - there it works perfect every time, whether I redeploy or not.

env.put(Context.SECURITY_PRINCIPAL, "oc4jadmin");
env.put(Context.SECURITY_CREDENTIALS, "MyPassword");
env.put("dedicated.rmicontext","true");
InitialContext ctx = null;
try {
ctx = new InitialContext(env);
// WHEN I REDEPLOY, CODE CRASHES ON THE NEXT LINE
Object home = ctx.lookup("ejb/TestWorkerAProxyBean");
