Websphere: Exception JNDI lookup
Hi All,
I am stuck up with JNDI lookup in WebSphere 6 from standalone non J2EE application client JVM.
Client JVM has thrown the following exception while lookup:
Feb 23, 2005 11:30:47 AM com.ibm.ws.naming.util.Helpers
WARNING: jndiGetObjInstNoop
Exception in thread "P=586654:O=0:CT" java.lang.ClassCastException: javax.naming.Reference
javax.naming.NameNotFoundException: Context: Cell/nodes/Node01/servers/server1, name: Node01Cell/nodes/Nod

lper.java:85)
Both the WebSphere container and standalone client uses IBM JDK 1.4.2 and I have placed all necessary JAR files in the client's CLASSPATH, but still the ClassCastException resulted.
Below is the sample code of the application client:
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "com.ibm.websphere.naming.WsnInitialContextFactory");
props.put(Context.PROVIDER_URL, "iiop://localhost:2809");
Context ctx = new InitialContext(props);
Object obj = ctx.lookup("System\config");Need help. Could someone please tell me what I am doing wrong?
Regards,
Srinivas
I'm having the same problem:

WARNING: jndiGetObjInstNoop

Adding <WAS_HOME>/lib/dynacache.jar into the classpath solved the problem.
My environment is: WAS 6.0.0.1, WebSphere MQ 6.0, JMS Client Java Application running in RAD 6.0

... 38 moreCan any body tell me what's wrong with it? i have seen all the stubs generated it is looking for but not able to load/recognize it? And also i need to mention other problem is that everytime i compile, deploy and start the server i am getting open failure exception and server not recognizing the ejb jar and if i close and restart the RSA server starts well.
Pls help me in solving this issue.Hi All
Two separate webapps, have different names for
Datasources, on the same host and port. Both
application work fine independently.
When we deploy both applications on the same app
server(websphere), whichever we executes first gets
its datasource from JNDI lookup and works fine, but
when we try second application it have problem in
finding its data source from JNDI lookup. If we start
this second application first, it will work fine, but
now another will have the same problem in its JNDI
lookup.
Any idea why.
Thanks
....RanvirHi Ranvir,
Do you mean you try to reach the same datasource with different names or do you try to reach different datasources over the same port?
If you try the first issue you shouldn't get any trouble. At least it works fine with JBOSS for example.
But if you try to do the latter in my oppinion you don't have a JNDI problem but a problem with socket binding: the two different databases must be contacted over different ports.
What do WebSphere's logs tell?
Best regards

Why only j2sdkee1.3 support JNDI lookup "java:comp/env" from remote client?
Hi:
I have been puzzled by this function of j2sdkee1.3.1 support JNDI lookup "java:comp/env" from client. I always think that "java:comp/env" namespace can only be access by the application server self for it is a private namespace. The weblogic and websphere doest support this.
Why?
Regards!
John LeeHi:I'm unable to get JNDI reference object from remote application client with "java:comp/env/ejb/<lookupName>".
The exception says:
Application threw an exception:javax.naming.CommunicationException: Cannot connect to ORB [Root exception is org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No]
The J2EE server and client are run on different machines, and needs to be like this. There isn't any problem with JSP/Servlet (cause they run/execute on the server itself). How will the client find out the JNDI refernce my mere specification of "java:comp/env/..."?
Am I making a mistake anywhere?
BEA Weblogic & IBM Websphere allows explicitly specifying the server name, while doing JNDI lookup. Is there anything similary for J2EE?
I couldn't find reference for this anywhere in the J2EE tutorial or EJB books.

BEA Weblogic & IBM Websphere allows explicitly specifying the server name, while doing JNDI lookup. Is there anything similary for J2EE?
I couldn't find reference for this anywhere in the J2EE tutorial or EJB books.

Hello Frnds,
I am using xdoclet 1.2 feature in my application to generate the stubs for ejb bean classes.
and i am using the websphere application server to deploy my application.
Please find the code below :
In Home class
public static final String COMP_NAME="java:comp/env/ejb/TestEJBLocal";
public static final String JNDI_NAME="ejb/TestEJBLocal";
In Bean Class
@ejb.bean name="TestEJB" view-type="local"
* local-jndi-name="ejb/TestEJBLocal"
* type="CMP" reentrant="False" cmp-version="2.x" schema="Test"
* primkey-field="testID"
For lookup:
public EJBHome lookUpHome(Class homeClass) throws HomeFactoryException {
try {
EJBHome ejbHome = (EJBHome) _ejbHomes.get(homeClass);
if (ejbHome == null) {
ejbHome = (EJBHome) PortableRemoteObject.narrow(_context
.lookup("*java:comp/env/ejb/TestEJBLocal*"), homeClass);
_ejbHomes.put(homeClass, ejbHome);
return ejbHome;
} catch (ClassCastException e) {
throw new HomeFactoryException(e);
} catch (NamingException e) {
throw new HomeFactoryException(e);
When i pass the COMP_NAME for lookup, application is throwing an exception like Name Not Found exception.
The problem i'm facing here is, JNDI lookup is not happening through COMP_NAME.
Could someone help me on resloving this problem.
Helping on othis highly appreciated :)
Cheers,
CapHi:I'm unable to get JNDI reference object from remote application client with "java:comp/env/ejb/<lookupName>".
The exception says:
Application threw an exception:javax.naming.CommunicationException: Cannot connect to ORB [Root exception is org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No]

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 :

JNDI Lookup in JSP fails for EJB 3.0
I am new to Java technology. I read the EJB FAQ, NetBeans docs and may forum discussions and I am still confused with the error I am having.
Background:
I have developed a persistance bean and related sessions beans (similar to the customer-cmp-ear application in the Java App Server samples). Now I am trying to access this bean using a JSP. After deploying the war file in the App Server and try to access the page, I get the following error.
javax.naming.NameNotFoundException: No object bound to name java:comp/env/ConsumerSessionLocal
After reading many articles, I understood that I dont have to prepare any descriptors, or JAR files for EJB 3.0.
Environment Details:
Java App Server Ver 9.0
NetBeans 5.5
I normally build the war files using NetBeans.
I use App Server Admin console to deploy the web applications using the above war file.
EJB details:
Persistance EJB : person.java
Session Objects
Consumer.java (this implements ConsumerSessionLocal, ConsumerSessionRemote). This Stateless bean accesses the methods in person.java.
ConsumerSessionLocal.java - local interface
ConsumerSessionRemote.java - remote interface
SearchConsumer.jsp
This JSP page is calling the ConsumerSessionLocal using the JNDI lookup through InitialContext.
Here is the Code snippet:
try {
InitialContext ic = new InitialContext();
Object o = ic.lookup("java:comp/env/ConsumerSessionLocal");
ConsumerSessionLocal consSession = (ConsumerSessionLocal) o;
I am able to see the jsp page in the browser, however, after a submit action, I get the Java Naming Exception error.
javax.naming.NameNotFoundException: No object bound for java:comp/env/ConsumerSessionLocal
I would appreciate your help/any of your thoughts.
Thanks in advance.
-RamI did not really solve it. Instead I used some of the tutorials that used JNDI lookup and modified those as my way forward. I did not really find out exactly what I was doing wrong.

JNDI Lookup in OC4J *AND* Tomcat 5 (not either/or)
I've been struggling to get a web application to deploy and run correctly on Tomcat 5.x. I couldn't ADF to look up the Datasource I'd set up in the Tomcat configs. After reading this forum post:
Problem deploying BC4J Toy Store app on Tomcat 4
I was able to run my test app successfully on Tomcat by prepending 'java:comp/env/' to the JNDI name of my Datasource in bc4j.xcfg. Unfortunately, specifying the JNDI name in this way breaks the JNDI lookup in the embedded OC4J container. The impression I got from the above forum post was that OC4J should be able to look up the data source when the name is specified as either jndi/myDataSource or java:comp/env/jndi/myDataSource. I can only get it to work with the former.
Is there a way to specify the JNDI name of a datasource in bc4j.xcfg such that both Tomcat AND the embedded OC4J container within JDeveloper will be able to look it up?
Thanks,
-MattTo answer my own question, a fairly straight-forward way of achieving this is to use two configurations for the application module: one for testing locally (the supplied configuration), and another one for deployment that is a copy of the first except for the JNDI name. I can switch between the configurations via the Databindings depending on whether I want to test locally or deploy to Tomcat.
This is certainly a useable solution, but I'm bothered by the fact that I need to reference the JNDI name in two different ways. Shouldn't this be container-independent?

I am using Jackrabbit Repository (jcr's implementation) as backend in my Web Appl.Whose data persists on Oracle Database. To make connection with Oracle database jackrabbit provide provision of JNDI Lookup to read the data source defined in WAS (using WAS 8.0.0.4 as App Server).
I am able to perform JNDI Lookup everywhere in my application,But in a flow where i am creating a Thread using Java Concurrent Api and insidethread's call() method when I am trying for JNDI Look following exception occurs –

Since we're mouting onto an NFS, these are the steps he took. I'm not trying to "hide" information or post as little as possible. What other info do you want? I don't know what you are referring to when you mention "Filer, make, model, software version"? Please elaborate. I was just trying to post to others that may have encountered this problem, and I get somewhat attacked by you. I don't assume anyone can read my mind (especially you).

JMS Wrappers can't cache JNDI lookups when using secured queues
Hi All!
We are working on a jms client, inside a webapp(servlets), using Weblogic 9.2 and Weblogic 10.3.
As we want to use secured queues and keep being efficient we tryed to use Weblogic JMS Wrappers, that should work according to the docs:
Enhanced Support for Using WebLogic JMS with EJBs and Servlets
http://download.oracle.com/docs/cd/E12840_01/wls/docs103/jms/j2ee.html
But we are facing a problem:
When we define a JMS Wrapper and try to cache JNDI lookups for the QueueConnectionFactory and Queue, as the docs recommend for efficiency, the connection to the queue is ignoring the user/pwd.
The JMS Wrapper is using <res-auth>Application</res-auth>.
We are creating the connection using createQueueConnection(user, pwd) from QueueConnectionFactory and after several tests it seems that the user and password are ingored unless a jndi lookup is made in the same thread, as if when there are not any thread credentials present user and password are ignored for the connection...
so the question is:
That behaviour goes against Weblogic JMS Wrapper documentation, doesn't it?
Is there then any other way to access efficiently secured queues using a servlet as a client? (iit's not an option for us to use mdbs, or ejbs).
If it helps, this seems related to this still opened spring-weblogic issue: SPR-2941 --> http://jira.springframework.org/browse/SPR-2941 and SPR-4720 --> http://jira.springframework.org/browse/SPR-4720

Quite a useful response .-)
Leaving aside the fact that weblogic behaviour with jms wrappers and secured queues seems to not be working as the docs says...
Talking about workarounds:
Both workarounds you suggest works, but as you already noted, creating a new JNDI context just to inject credentials into the threads is overkill when high performance is needed.
I also found more information about the same issue here: http://sleeplessinslc.blogspot.com/2009/04/weblogic-jms-standalone-multi-threaded.html
And he suggest the same workaround, injecting credentials
So I tried the second approach, successfully, injecting credentials into the thread using the security API.
This way, using JMS wrappers and injecting credentials into the thread we get the best performance available, caching resource using wrappers and using credentials in a somewhat efficient way.
Now the test snippet looks like this:

Queue JNDI lookup in a clustered environment
Hey all,
I know in a 6.1 cluster, the queues/JMS servers can only reside on one
server.
How can i lookup a queue from internal code from one of the off servers? The
JNDI lookup doesn't grab it, throws an object not found exception. Do I need
to
be using the createQueue() method in the QueueSession class?
It's fairly critical to know this to get our app up on the cluster, so
any help would
be very appreciated!
Thanks,
Greg
A dumb question - how do I specify JNDINameReplicated=false? I am using WLS 6.1
SP3 and in my config.xml I have
<JMSTopic Name="topicA" JNDIName="topicA" JNDINameReplicated="false" />
but WebLogic does not like it.

JNDI lookup in a clustered environment
Hi,
I have deployed my application on a clustered environment containing one admin
server and two managed servers. The application is deployed on the managed servers.
We have a DNS for these two managed servers.
Currently, I am using t3:localhost:portnumber to get an initial context for JNDI
lookup.
But this will not provide perfect load balancing, since each server side component
(EJB) will lookup for a needed component on the same server itself.
Is there any way to get the Initial Context by using the DNS name?
I tried t3:DNSName (Our DNS is created till the port number. e.g. http://DNS points
to http://Managedserver1:portnumber and http://Managedserver2:portnumber
It works, but is random. Sometimes, it gives me the following exception:
Root exception is java.net.ConnectException: t3://DNS Name: Destination not
reachable using: 't3'
Could someone help me figure out a way to do this in a better way?
Thanks,
Aparna
If you don't want or have money to use external load balancers you should be using
the DNS entry as t3://server1:port,server2:port (you indicated you are using http.
Also make sure your network elements between the client and the servers allow
t3 protocol if there is packet filtering).

JNDI lookup problem in WAS 5.1
Hello all,
I have generated an EAR using XDoclet and MyEclipse. When I deploy this EAR on WAS 5.1, I get the following exception:

at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)First of all, I don't really understand what the error means. 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
-ybh6336Hello all,
I'm still stuck on this issue. Following are the entries related to my
application when I do a 'dumpNameSpace':
28 (top)/nodes/WarHog/servers/server1/ejb/tedi/TEDIObjectManager

com.wdc.tedi.interfaces._TransformationEngineHome_StubObservations:
- 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:
/* @ejb.bean name="TEDIObjectManager"
* display-name="TEDIObjectManager"
* description="TEDIObjectManager"
* jndi-name="ejb/tedi/TEDIObjectManager"

* view-type="both"
* @ejb.util generate="physical"
* @ejb.ejb-ref ejb-name="TEDIObject"
* view-type = "local"
* ref-name = "ejb/TEDIObjectLocal"
* @oc4j.bean jndi-name="ejb/tedi/TEDIObjectManager"
*/My ejb-jar.xml looks like following for that bean:

</ejbRefBindings>
<enterpriseBean
xmi:type="ejb:Session"
href="META-INF/ejb-jar.xml#Session_TEDIObjectManager" />
</ejbBindings>I know I'm swamping the post with code, but please let me know if anyone finds something unusual.
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

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
