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:

     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 ?

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 :

WLS 6.1 And EJB Descriptors.

I have been meesign around with WLS6.1 and tryign to get my deployment
descriptors online. The auto generaator made a mess of things. However, why
is it that I cant find where to enter a JNDI name for my beans or their refs
and why cant I find out how to spcify a topic for a JMS bean. Im a tad lost
and would appricate some help.

What's that "auto generator" you're talking about?
=========
The JNDI name is specified as the <jndi-name> element of
weblogic-ejb-jar.xml. This would be the last element of each bean's
description. Example:
<weblogic-enterprise-bean>
<ejb-name>example</ejb-name>
<jndi-name>beanJNDIName</jndi> 
</weblogic-enterprise-bean>
=========
JMS topics should be specified as resource references. Example:
In ejb-jar.xml:
<enterprise-beans>
<entity> 
<resource-ref> 
<res-ref-name>jms/aTopic</res-ref-name>
<res-type>javax.jms.Topic</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</entity>
</enterprise-beans>
and in weblogic-ejb-jar.xml:
<weblogic-enterprise-bean>
<ejb-name>example</ejb-name>
<reference-descriptor> 
<resource-description>
<res-ref-name>jms/aTopic</res-ref-name>
<jndi-name>example-topic-jndi-name</jndi-name>
</resource-description>
</reference-descriptor>
<jndi-name>beanJNDIName</jndi>
</weblogic-enterprise-bean>
and then you can look up this in the code with:
Topic t = (javax.jms.Topic)ctx.lookup("java:comp/env/jms/aTopic");
Good luck,
Emmanuel

EJB question: How to use abstract class in writing a session bean?

I had written an abstract class which implements the session bean as follow:
public abstract class LoggingSessionBean implements SessionBean {
protected SessionContext ctx;
protected abstract Object editRecord(Object obj) throws Exception;
public LoggingSessionBean()
super();
private final String getBeforeUpdateImage(Object obj) throws Exception {
// implement the details of extracting the backup image ...
public void setSessionContext(SessionContext ctx)
this.ctx = ctx;
private final void writeThisImageToDatabase(String aStr) {
// connect to database to write the record ...
public final Object update(final Object obj) {
try {
final String aStr = getBeforeUpdateImage(obj);
writeThisImageToDatabase(aStr);
editRecord(obj);
} catch (Exception e) {
ctx.setRollbackOnly();
This abstract class is to write the backup image to the database so that other session beans extending it only need to implement the details in editRecord(Object Obj) and they do not need to take care of the operation of making the backup image.
However, some several questions for me are:
1. If I write a class ScheduleSessionBean extending the above abstract class and the according 2 interfaces ScheduleSession and ScheduleSessionHome for this session bean (void update(Object obj); defined in ScheduleSession), do I still need to write the interfaces for LoggingSession and LoggingSessionHome?
2. If I wrote the interface LoggingSession extending EJBObject where it defined the abstract methods "void update(Object obj);" and "void setSessionContext(SessionContext ctx);", that this meant I needed to write the ScheduleSession to implement the Logging Session?
3. I used OC4J 9.0.4. How can I define the ejb-jar.xml in this case?

Hi Maggie,
1. do I still need to write
the interfaces for LoggingSession and
LoggingSessionHome?"LoggingSessionBean" can't be a session bean, because it's an abstract class. Therefore there's no point in thinking about the 'home' and 'remote' interfaces.
2. this
meant I needed to write the ScheduleSession to
implement the Logging Session?Again, not really a question worth considering, since "LoggingSessionBean" can't be an EJB.
3. I used OC4J 9.0.4. How can I define the
ejb-jar.xml in this case?Same as you define it for any version of OC4J and for any EJB container, for that matter, since the "ejb-jar.xml" file is defined by the EJB specification.
Let me suggest that you create a "Logging" class as a regular java class, and give your "ScheduleSessionBean" a member that is an instance of the "Logging" class.
Alternatively, the "ScheduleSessionBean" can extend the "Logging" class and implement the "SessionBean" interface.
Good Luck,
Avi.

Setting up the environment in WLS 7.0 and deplying?

Hi,
Previously I have used WLS 6.1.
I have set up the properties file and the required folders in the mydomain folder for the classes. It worked fine for me.
Now when I am using WLS 7.02.
This looks complicated. I have seen the documentation, it tells about different folders other than config like stage and server.
My question is can I use the same old environment setting as in 6.1 in 7.02 and deploy the applications as before.
If not, am I missing anything.
If anyone has worked on WLS 7.02, please let me know how you have set up the environment and deplyed the applications.
Thanks in Advance

You dont have to setup anything extra for 7.x deployment. The server and stage directories will take suitable defaults.
See 'Using WebLogic Server 6.x Deployment Protocol' in http://e-docs/wls/docs70/programming/deploying.html

ConnectionPool problems with WLS 7.0 and Oracle 9.2

Hi,
We are using WLS 7.0 SP4, and Oracle 9 and the Oracle thin driver type 4. In our
application on the productive system (and only there) we constantly encounter
a whole set of SQLExceptions which have all in common that the Connection from
the pool is not valid any more when the application tries to use it.
Typical, recurring error messages are:
- Exhausted ResultSet
- Connection has already been closed
- Closed Statement
- Transaction is no longer active - status committing
- NullPointerException at
weblogic.jdbc.pool.Connection.prepareStatement()
There are no special Statements which create these errors. They are spread at
random across practically every query the application creates, and the same queries
sometimes succeed and sometimes fail.
I double and triple checked that all Connections, Statements and ResultSets are
closed immediately after use. As an example, I attached a code snippet and a resulting
StackTrace which.
The problem also seems to occur only with an (unknown) minimum of concurrent usern,
since in the approval tests on an almost identical test system these errors never
occurred.
I also followed the advice from Oracle and installed the latest Oracle JDBC driver
(Oracle 10g) - to no avail.
What else can I do?
Another question: Is it correct that my Oracle JDBC driver is in the application
classpath (via a reference in the Manifest file of the application jar), not in
the system classpath? There has never been a problem with that, but in a Newsgroup
answer from Nov 10, 2003 (subject: "ResultSet closes prematurely"), Joe Weinstein
suggested to "get it listed at the
front of the -classpath argument that the startWebLogic script creates for the
java line that starts the server".
I hesitate to do so, since the driver is in a standard WebApp- directory, WEB-INF/lib.
Is it possible and safe to add a jar located there to the system classpath? If
it is possible, why is it necessary?
Best regards,
Andreas Zehrt

Hi Joe,
Your hint that there is a threading problem was right:
On further investigation of the code I found out that the class that passes the
Connection to the DAO not only stores it as a member at some point (which is not
a good idea anyway) but is also a singleton - then, of course, it's no surprise
that the Connection gets invalid in a incalculable way when concurrent threads
share it.
The singleton instantiation was not so obvious because the way of instantiation
is controlled by a configuration parameter that can be overridden at different
levels.
I changed it and the productive logfiles indicate that the SQLExceptions related
to that class have disappeared.I am happy to have helped.
So, thanks a lot for the advice.
But I am still wondering why this code has worked for so long a time with WLS
5.1 and Oracle 8 (the system has been productive for over 2 years). Even in the
approval tests with WLS 7.0 and Oracle 9, we did not run into problems, although
it was multi-user environment.Mo idea.
I still believe that there is a difference between WLS 5.1 and 7.0 in the way
it treats pooled Oracle JDBC Connections. I wished both Oracle and Bea could be
a little more explicit about those changes and possible version incompatabilities
beyond the general advice "use the latest thin driver".Though I can think of no change to our pooling which would have had any material
effect in this case, I will certainly do what I can to see that our documentation
is explicit about changes.

where it was originally closed.
- Closed Statementsame as above.
- Transaction is no longer active - status committingThat implies your code is obtaining a connection from a transactional
datasource,

with,
is finished.
- NullPointerException at

We also ship
an oracle thin driver, which becomes obsolete soon...
I am concerned that your code creates pool connections to be used later.
The problems
can arise if more than one thread ever gets the same connection, or if
the connection
is used in the same thread, spanning transactions. It does also seem
that there may
be a threading issue, because if two threads each call the code to create
a connection,
and two connections are made, but one over-writes the other, the two
threads can
end up using the same connection, and closing it. The over-written one
never gets closed,
resulting in that leak message you got...
Joe
The Connection parameter is opened by a business component class, ComaServiceProviderClassicImpl.It is propagated through
several classes in the business layer, but not used, until the DAOtakes it to make the query.
So, the Connection is closed where it was opened, not in the DAO class.
public class ConcernDAOImpl extends BaseDAO {
     public Collection getConcernsForIncidents(Connection conn, Collectionincidents)
throws DataAccessException, ConstraintException, ComaParseException{>
sqlMessage.append(")");
String sqlStmt = sqlMessage.toString();
PreparedStatement pstmt = null;
ResultSet rs = null;
try {
pstmt = conn.prepareStatement(sqlStmt);
rs = pstmt.executeQuery();
while (rs != null && rs.next()) {
final Concern concern =
new Concern(DAOUtil.getComaOID(rs, ComaDBNames.KDANR));
concern.setIncidentOID(DAOUtil.getComaOID(rs, ComaDBNames.KDAVGENR));
return concerns;
} catch (SQLException sqle) {
// Wrapps real SQL exception
String[] message = new String[]{sqle.getMessage(), sqlStmt};
throw new DataAccessException(ExpCode.S_ORACLE_SQL, message,
sqle);
} finally {
closeAll(rs, pstmt);
_logger.exitDebug(method);
Here, the Connection is acquired and finally closed
public class ComaServiceProviderClassicImpl {
     public void updateComplaint(
final Request updateRequest,
final ResponseSingleElement response,
final Principal principal)
throws SystemException {
try {
logger.info("updateComplaint", "store incident");
// store the incident in the database
incidentManager.storeIncident(getConnection(), updateIncident);
// reload the incident from Cache and / or the databaseto get the ContactReferences.
Incident returnIncident = incidentManager.loadIncident(//IncidentManager passes the Connection to the DAO
getConnection(), updateIncident.getOID());
} catch (RemoteException rex) {
// remote exceptions
rollbackIfNecessary();
CoreUtils.unwrapRemoteException(rex, logger);
} catch (SystemException e) {
// all other exceptions --> rollback if necessary and rethrow
rollbackIfNecessary();
throw e;
} finally {
removeConnection();
logger.exitDebug("updateComplaint");
This is the resulting StackTrace:

Weblogic 6.1 and 7.0 EJB interoperability

Are WebLogic 6.1 and 7.0 EJBs interoperable? Can a client EJB on 6.1
call another EJB on 7.0 and vice versa?
Weblogic 5.1 and 6.0 were not interoperable. Interoperability was
achieved with versions 5.1 sp12 and 6.1 sp 3.

We want to deploy Servlet/JSP in JServ and call the EJB's deployed in iPlanet App Server 6.0 SP2. How do we make the getInitialContext Call be able to access the EJB's.

Additionally what configurations do we need to make sure we have on JServ (Third party Servlet container) to make sure that the iPlanet EJB's can be accessed.

Let me preface my instructions with the comment that this isn't a good idea. Although the J2EE specification allows you seperate your web container from your EJB container, in practical deployments it is a bad idea. The overhead of doing RMI/IIOP calls to an external container as opposed to making inter-JVM calls means that you can expect roughly an order of magnitude less performance than if you colocate your web and EJB containers. (This is why all EJB containers are also web containers, or at least have the provision to install themselves in the same JVM as a web container.)
That said, if you do not have the option to move the servlets to iAS, you can access EJB's in iAS from JServ the same way that you would from any remote client. Take a look at the following information for more detail:
Chapter 9 of the developer's guide ( this shows you what changes you need to make to the remote JVM (at JServ) and in the EJB's that you are exposing).
The RMI/IIOP sample application. This gives you an example of how to access EJB's from outside the container.
(To answer your direct question, the following code will get the initial context. But if you don't take all of the other configuration steps, this code won't work:
env.put("java.naming.factory.initial", "com.sun.jndi.cosnaming.CNCtxFactory");
env.put("java.naming.provider.url", "iiop://" + host + ":"+port);
Context initial = new InitialContext(env);
I'd also suggest that you approach the task with the following approach. (Assuming that I haven't managed to convince you that this is a really bad idea.)
1. Get your EJB's working on iAS. Test them with servlet harnesses running on iAS.
2. Get your servlets working on JServ, if they aren't already.
3. Create a simple standalone Java application as a test harness for EJB's. Follow the RMI/IIOP instructions until you get this test harness working.
4. Create a simple servlet test harness in JServ to access your EJb's. Follow the JVM setup instrucitons until you get this working.
5. Actually integrate the EJB's with your production application.
I say this because there are about five trillion things that can go wrong in this process. Although the troubleshooting steps in the docs are helpful, I find that it helps to get one thing working at a time. It's very frustrating to spend a day trying to resolve JNDI issues only to find out that you have your CXS configured improperly.

Mod_weblogic.c in wls 6.1 and case insensitive URL

Hi,
We need to send URL of a given application to a dedicated managed server (7126), the rest on the "default" managed server (7122). The URL may come in uppercase or in lowercase. I do not understand in the httpd.conf below, why only the "/db/owa/pp_pack" Urls are sent to port 7126, but not the "/db/owa/PP_PACK" which go the the 7122.
Thank's for your help.

Alex,
I am facing the same problem as you. It works on certain machines but others.
Would like to know the answer if you already have one. Thanks

I think you may find helpful information here:
A Basic Guide for Migrating to Intel-Macs
The Knowledgebase article Intel-based Mac: Some migrated applications may need to be updated refers to methods of dealing with migrating from PowerPC chips to Intel with the Migration Assistant safely. The authors of this tip have not had a chance to verify this works in all instances, or that it avoids the 10.6.1 and earlier Guest Account bug that caused account information to get deleted upon use of the Migration/Setup Assistant. However, a well backed up source that includes at least two backups of all the data that are not connected to your machine will help you avoid potential issues, should they arise. In event it does not work, follow the steps below.
If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
Classic Environment, and subsequently any Mac OS 9 or earlier applications
Screensavers written for the PowerPC System Preference add-ons
All Unsanity Haxies Browser and other plug-ins
Contextual Menu Items
Applications which specifically require the PowerPC G5 Kernel extensions
Java applications with JNI (PowerPC) libraries
See also What Can Be Translated by Rosetta.
In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior, TechTool Pro , SuperDuper , and Drive Genius work properly on Intel-Macs with Leopard. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries. Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.

Transferring data with Setup Assistant - Migration Assistant FAQ
Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs. The initial section below discusses Target Disk Mode. It is then followed by a section which discusses networking with Macs that lack Firewire.
If both computers support the use of Firewire then you can use the following instructions:
1. Repair the hard drive and permissions using Disk Utility.
2. Backup your data. This is vitally important in case you make a mistake or there's some other problem.
3. Connect a Firewire cable between your old Mac and your new Intel Mac.
4. Startup your old Mac in Transferring files between two computers using FireWire.
5. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
1. Set up a local home network: Creating a small Ethernet Network.
2. If you have a MacBook Air or Late 2008 MacBook see the following:
MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch, Late 2008)- What to do if migration is unsuccessful;
MacBook Air- Migration Tips and Tricks;
MacBook Air- Remote Disc, Migration, or Remote Install Mac OS X and wireless 802.11n networks.
Copy the following items from your old Mac to the new Mac:
In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
In your /Home/Library/ folder:
/Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)
Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
/Home/Library/Keychains (copy the whole folder) /Home/Library/Mail (copy the whole folder) /Home/Library/Preferences/ (copy the whole folder) /Home /Library/Calendars (copy the whole folder) /Home /Library/iTunes (copy the whole folder) /Home /Library/Safari (copy the whole folder)
If you want cookies:
/Home/Library/Cookies/Cookies.plist /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
For Entourage users:
Entourage is in /Home/Documents/Microsoft User Data Also in /Home/Library/Preferences/Microsoft.
Credit goes to Macjack for this information.
If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

Good afternoon ladies and gentlemen!
My question concerns the impossibility to open RAW-files directly from the program Adobe Bridge. At the moment when you open a RAW-file from Adobe Bridge by double-clicking, RAW-file is opened only in Photoshop. In the settings Adobe Bridge - in "open RAW-files by double-clicking in Adobe Camera Raw» box is checked. When you try any changes in the settings Adobe Bridge system displays a message:
Bridge's parent application is not active. Bridge requires that a qualifying product has been launched at least once to enable this feature.
The entire line of Adobe products on my computer updated to the latest updates. Previously, a family of products Adobe Photoshop on your computer is not set. Computer - PC, Windows 7 Enterprises.

Mpeg-2 flags, dvdsp, and 23.976 video question

just got through this thread:
http://discussions.apple.com/thread.jspa?messageID=9786956
and have a remaining question. i looked at the m2v file in
mpeg streamclip and i see:
Video Tracks:
224 MPEG-2, 720 × 480, 4:3, 23.976 fps, 7.70 Mbps, upper field first
is the 'upper field first' just a flag to tell how to deal with
this file? or is it stating that the file is interlaced with the
upper field first?
the intent is to make a progressive dvd at 23.976. the original
material is film, captured and edited at 23.976, progressive. the
material was captured off of an old projector, a frame at a time,
with a digital still camera, so the original has no interlacing
or fields. this went to make an image sequence, which was rendered
to a qt movie at 23.976, also progressive, no fields. it was then
output through compressor to the m2v file which produced the mpeg
streamclip stream info dialog quoted above.
thanks,
BabaG
