Is the WL 6.1 CORBA 2.0 compliant?

Hi there,
is the Weblogic 6.1 compliant with CORBA 2.0?
I found only the information that WL 6.1
supports the CORBA/IIOP 2.4.2 Specification.
Thanks a lot and have a nice weekend.

I found only the information that WL 6.1 supports the CORBA/IIOP
2.4.2 Specification.Only for IIOP transport for EJB purposes, AFAIK.That's a fair summary.

-- OK. The means that is not possible to create our
own CORBA Server Objects.
For me it is ok because I prefer a very good and simple
EJB solution.
Thanks and I'm waiting for response :-)

Does the bea content repository is JSR-170 compliant

Hi ALL,
Actually i want to use the bea content repository form my web service so should i go for SPI interface or i should use the JCR (Java Conetnt repository)API.
But i would be able to use the JCR interface only if the bea content repository is JSR 170 compliant.
Pls. suggest me the right way.
Thanks.........

The BEA repository is not yet JSR-170 compliant.

How to avoid the attach error in sparc(64bit) driver complied with GCC

If you want to avoid the error,failed to attach in sparc 64 bit driver ,
you must add the flags .as bellowing.
CC = /usr/local/bin/gcc
LD = /usr/ucb/ld
GCCFLAGS = -m64 -mcpu=v9 -fno-builtin
CFLAGS = -O $(INCL) $(GCCFLAGS) -D_KERNEL -D_SYSCALL32 -Wall

Vini160409, You totally Rule!
I noted just one brief update: I am using Access 2007, and my database has the suffix .accdb. That uses a slightly different driver than the one described in your (very careful) instructions; fortunately, it was also available in the drivers in the program odbcad32.exe in the System 32 folder, so it was available to me when I added the new database from within the SysWOW64 folder. This fix allows me to use LiveView with a ColdFusion site from within DreamWeaver. Thanks much for making this public!

Why are there CORBA error messages -- COMM_FAILURE when using the orb obj?

Hi Guys,
I followed the tutorial http://download.oracle.com/javase/6/docs/technotes/guides/idl/GShome.html
compiled and run the code. Everything works fine however whenever I use the ORB orb object I get the following message
both in my Naming Service and the HelloServer output:

Is the JTS Transaction Manager Java Mapping of Corba OTS using JSE Impl?

Hi All,
I was reading the Java Transaction Service Specification .95 Draft, and I am curious if the Java Mapping of Corba OTS 1.1 Interfaces Implementation is generally referring to the Java Standard Edition implementation of these classes, specifically the IDL code that is converted into Java classes in the tools.jar. I attempted to manually compile the IDL code in the OMG Transaction Service Specification 1.4 using idlj in JDK 1.6 and ran into one compilation issue after another, until I realized The CosTransactions Module, and other required Corba IDL interface are already converted into Java classes in the tools.jar of the JDK. My assumption was I should map directly to the classes in the JDK if I create a Java Transaction Manager for the Java Transaction Service Specification?
Any help you can provide on this subject will be appreciated.
Thanks,
Aaron

Is there some limitation for the numbers of CORBA objects under Java IDL

Operation System : Windows 98 Second Edition(4.10.2222)
Java 2 SDK version :
java version "1.4.1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-b21)
Java HotSpot(TM) Client VM (build 1.4.1-b21, mixed mode)
I have programmed a distributed application with java IDL.
there are a lot of CORBA objects in my application and all of those objects must registered with the same orb.
At the beginning,I launched 4 CORBA objects,which is the least number of CORBA objects needed to run my application,and the application runs well.Then I increased the number of CORBA objects gradually.But when the number of CORBA objects has been changed to 6,the application runs instably,that is, the application sometimes runs well,and sometimes it generates an error when I launched my client-side program,the error is as follow:
org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No

at Client.main(Client.java:19)
the NO.19 line in Client.java is :
NamingContextExt ncref = NamingContextExtHelper.narrow(comobj);
The COMM_FAILURE/SUN-201 means CONNECT_FAILURE.
This will happen if a client gets a reference to an object reference whose server is not yet started,or perhaps not yet initialized.
But I think I have waited for enough long time before launched Client.java?Can anybody help me?Thanks very much....

We are trying to connect to corba naming services using Apache/Tomcat5.0 .We are using servlets to call the Corba services.
We are initializing the ORB as follows:
Properties p= new Properties();
p.setProperty("org.omg.CORBA.ORBInitialHost","ramesh");
p.setProperty("org.omg.CORBA.ORBInitialPort","1234");
p.setProperty("org.omg.CORBA.ORBClass","com.sun.corba.se.internal.iiop.ORB");
ORB orb = ORB.init((String[])null,p);
nmref = NamingContextHelper.narrow(orb.resolve_initial_references("NameService"));
NameComponent[] dmNamingComps ={new NameComponent("DATAMgt","")};
DataManagement.DatamanagementFactory data_factory_ref= DataManagement.DatamanagementHelper.narrow(nmref.resolve(dmNamingComps ));
masterDataref = data_factory_ref.createMasterData();
=====================
when we run the program:
we are getting the error message:

Can anybody help ?Do we need any other configuration setup apart from the code in Apache/Tomcat?

Set Port to be used by client orb corba for the response to a server

I have a client corba application, and i need to set the port used for corba response on the client host.
How can i set the port used on client for response?
Client Server
<ClientHost>?port?--------------------->4444<serverHost>
Thanks

You mean the local port at the client. It's used for the entire connection, not just the response. You should let the system allocate this rather than trying to control it yourself. Otherwise you restrict yourself to only one connection to the ORB from the client (e.g. no multithreading).
You should arrange with your firewall to allow anyclient port to connect to the ORB.

How to get rid of the Exceptions

When I tried to open the client i.e User interface which is MainMenuApp received NO_PERMISSION CORBA exception while attempting to get an initial reference to the mvcf_ControllerFactory from the FactoryFinder. Software defect that should be addressed is that the UI did not recover after catching the exception and required a restart of the UI to connect.
The problem is that cleanWorkspace() in CorbaAdapter doesn't have any failover logic in it at all. The adapter is assumed to be good and if it is not cleanWorkspace() attempts to use a factory that doesn't exist. This throws an uncaught NullPointerException that blows out to MainMenuApp where it is interpreted as a fatal exception and prevents the main menu from starting. So please help me in writing the failover logic in CorbaAdapter
The code for cleanWorkspace is
* Cleans up the entire logical positions workspace.
* @throws AdapterException UserError or Error occured
public synchronized void cleanWorkspace() throws AdapterException
cut_ContextInitData cid = getContextInitData();
cid.clientId = "*";
MVC2CleanWorkspaceCmd cmd = new MVC2CleanWorkspaceCmd(cid);
execute(cmd);
I am giving the whole logic of Corba Adapter. This might help:

How to invoke A CORBA-Java Client Application, from Oracle???

Hi,
I have a CORBA-Java Client Application, which takes the input parameters from a Oracle table and calls the CORBA Server, passes these parameters to the C++ Server Application and gets the results back thorugh CORBA.
My problem is, this java application needs to be invoked, when ever there is a new record in the Oracle table.
I am not sure if i can use Java Stored Procedures in Oracle in this case, because my app is in Sun JVM and i am using BEA WebLogic Enterprise 5.1 for the CORBA.
Is there any other way by which i can invoke this app, when a new record is updated in the Oracle table?
Currently, i have just put a TIMER in my java App, to check the oracle table in every few seconds, to see if there is a new reocrd. If it finds a new record it invokes the corresponding class(corba class), or else just keep sending a messsage that no new record is available.
The problems i am facing in this method are as follows;
1. Unnecessarily, the application has to keep on running if there is no request coming frequently.
2. When there is a new record found, the Corba Class is called and the whole process (till it gets the result back from the server) takes about 20 - 30 secs. But within this period, if there is another record coming into Oracle table, my timer class doesnt invoke another corba class....(though i am using multithreading by using the RemidTask method in the timer.schedule.
(timer.schedule(new RemindTask(),10,5*1000);)
3. Also, if during the first call, there is some error, then the whole process exits, instead of another process running parallely (when a second new record is found).
So how does this timer class act like a multithreading process?
Well, i hope i am not confusing....Please let me know if anyone wants bit more elaboration on this.
It would be really helpful if someone can suggest some answer to my problem.
Thanks in advance.

Thank you very much Keith.
Though i am really getting a hope of solving this problem, from you answer, i am actually not 100% sure if i understood your reply properly.
First of all, about
1. "use the update stored procedure to place the updated record (or unique index) onto an Oracle Application Queue."
-- Why do i need to put the record in the AQ. (Frankly speaking, at this moment i dont have much idea about AQ, probably i can learn more about it from oracle technet site? Or would u suggest anything else?)
Then,
2."Your app then waits on this queue and for each new message, consumes it, gets the data required from the AQ load (e.g the index and or record), and fires off the CORBA class"
-- How does my application stay in the queue? and gets the data from the queue?
Of course, as far as i understand, i am going through the same principle...keeping on running a timer class, which keeps on checking the table for a new record, and when it finds, it calls the CORBA class.
Of course, i feel there should be a difference in running the timer continuosly and staying in queue. However i am totally unaware, how can i make my java app to wait in the queue and waits for a new record?
Can you please elaborate your answer a bit more, because i dont know about the AQ, that you have mentioned.
Thank you very much in advance for your time. But please know that it will be of great help to me and hence will be higly appreciated.
Regards,
Subhasree.

The delegate has not been set!

I am trying to get my java code to do a rebind with a OpenORB naming service. The connection to the naming service works, but when I get to the line:
ncRef.rebind(nameComponent, server_name); I get the error:
org.omg.CORBA.BAD_OPERATION: The delegate has not been set! minor code: 0 completed: No
at org.omg.CORBA.portable.ObjectImpl._get_delegate(ObjectImpl.java:55)
at org.openorb.iiop.CDROutputStream.write_Object(CDROutputStream.java:1091)
at org.omg.CosNaming._NamingContextExtStub.rebind(_NamingContextExtStub.java:351)
at LogManager.main(LogManager.java:107)
Can anyone please tell me what this is and offer a means to fix or get around this. I have been messing with this for days and can't seem to get anywhere. Thank you very much for you help in advance.

You can ignore this. I figured it out. With the OpenORB operations I was trying to use the POA means of doing this, when in turn I wanted to use the BOA. So as soon as I started using the line boa.connect(orb); and the boa methodology, then everything started to work fine.
thanks

2 Java Applications Talking Corba or Socket communication

So, I have 2 Java applications that need to talk to each other remotely. One application send a request to the other with an ID. After the other application processes that request, it send back a status with the ID.
I am not up on Corba, but am familar with Socket based communication. Before I just go and code it with how I am familar, I was wondering if someone had a small summary of why I should try and take the time to learn Corba and code the communication that way.
Creating and using the Sockets in Java is so simplistic, is that the case with Corba? Sorry for the general question, but need some advice from the experts. Thanks....

Normal CORBA (as in Java IDL) is probably way too complicated for what you're trying to do, unless you're thinking of someday having the programs talk with non-Java programs.
I'd start with Java RMI rather than RMI-IIOP since you can probably find more tutorials and docs on it (though the RMI-IIOP 1.4 docs here are really quite good). That way, you're writing everything in Java, at least.
For remote object systems, all the advantaged of object oriented programming come into play, especially extensibility. What if you need to change the wire format to add more information in your socket system but need to maintain compatibility with older clients? What if you need to add security or handle multiple clients at once? What if you'd rather rely on existing serialization methods rather than code your own wire format for everything you want to send (making you write more code)? You can serialize any Java Serializable over Java RMI. That lets you send things without violating encapsulation. What if you want to talk to programs that aren't written in Java? What about automatic failure recovery if the server crashes? etc etc.

Can someone tell me where to get information about the search function in Swift

I need to put a search function into an app I am building and I have no idea where to look for information as to code, where to put the code and the text that it is going to search ( a book's worth) where do I put that file. Any help would be great. Thank you in advance.

Dipak,
Two things to try:
1. Check the Oracle8i EJB and CORBA Developer's Guide. It is available online from OTN in the documentation area.
2. Posting your note to the Oracle8i JVM technical discussion forum.

Org.omg.CORBA.NO_RESPONSE: vmcid: 0x0 minor code: 0 completed: Maybe

Hi,
We are using a ejb to connect to corba server (tuxedo) at the backend , in most cases things are fine , but if the server takes more than 65 - 75 secs the above error occurs. The processing at the backend completes just fine ..
We are not using network access points. I have tried setting the following properties to no avail
IdleIIOPConnectionTimeout="300"
CompleteIIOPMessageTimeout="300"
The ejb is invoked via a jsp. The code snippet to invoke the corba server is as follows
 //Use the factory finder to find the connection factory. Replace
 // here with appropriate connection factory
 org.omg.CORBA.Object connection_fact_oref = IIOPFactory.getFactoryFinder().find_one_factory_by_id(TxnConnectionFactoryHelper.id());
 // Narrow the connection factory.
 TxnConnectionFactory connection_factory_ref = TxnConnectionFactoryHelper.narrow(connection_fact_oref);
 // Find the connection object.
 TxnConnection connection = connection_factory_ref.getTxnConnection();
 recv_buff = new byte[Constants.XML_BUFF_LEN];
 //Prepare for the output
 org.omg.CORBA.StringHolder buf = new org.omg.CORBA.StringHolder(new String(recv_buff));
 //Invoke the neccessary method
 TXNMON.MessageHolder msgHldr = new TXNMON.MessageHolder(new TXNMON.Message(sb));
 int arrayLength = sb.length;
 connection.sendByteMessage(arrayLength, msgHldr);
Meanwhile we are trying to reduce the server processing time ...
This is ruining my XMas, any help will be greatly appreciated.
Thanks,
George

Corba in weblogic 5.1

i wanna use corba Server ... what setting should i make in classpath and
path to work with corba
thanks in advance
khaleel

1. This is all in the documentation for whatever corba service/orb you wish
to use. Add those classes to the classpath of wls. You can start up the
orb on server start by using a startup class.
