CORBA Event Service problem

Greetings,
I hope I'm posting on the right section :)
I'm new to ORBacus with Java and I'm having a problem when trying to use the Event Service.
I have this pull client:
Any event=null;
EventChannel eventChannel=null;
ConsumerAdmin consumerAdmin=null;
ProxyPullSupplier pullSupplier=null;
try{
         eventChannel = EventChannelHelper.narrow(obj);
         consumerAdmin = eventChannel.for_consumers();
         pullSupplier = consumerAdmin.obtain_pull_supplier();
            // I need to do this to bind proxy to the Event Stream, correct?
           // The problem is on the parameter it takes, a PullConsumer
         pullSupplier.connect_pull_consumer( new MOTDPullConsumer() );
         event = pullSupplier.pull(); 
}(...)So i'm actually having problems implementing the PullConsumer interface:
import org.omg.CORBA.*;
import org.omg.CosEventChannelAdmin.*;
import org.omg.CosEventComm.*
public class MOTDPullConsumer implements PullConsumer{
    public void disconnect_pull_consumer(){
     System.out.println("Pull consumer off!");
}This causes a compilation error which I can't determine why, the interface only specifies the method implemented above:
MOTDPullConsumer is not abstract and does not override abstract method createrequest(org.omg.CORBA.Context,java.lang.String,
org.omg.CORBA.NVList,org.omg.CORBA.NamedValue,
org.omg.CORBA.ExceptionList,org.omg.CORBA.ContextList)
in org.omg.CORBA.Object
Anyone seen this happen before?
Thanks in advance! :)

I solved it by passing null to connect_pull_consumer():
try{
     eventChannel = EventChannelHelper.narrow(obj);
     consumerAdmin = eventChannel.for_consumers();
     pullSupplier = consumerAdmin.obtain_pull_supplier();
     pullSupplier.connect_pull_consumer( null );
     event = pullSupplier.pull();
And did the same to connect_push_supplier() on the server side - it's all working OK now. Here are two fine links on this matter, if anyone ever needs it:

  • Can you use CORBA Naming Service with javax.naming.event.EventContext?

    Can you use CORBA Naming Service with javax.naming.event.EventContext?
    It seems like it doesn't work. When I try to do something like
    EventContext eCtx_ = (EventContext)namingCtx_.lookup("");
    I'm using JacORB's naming service.
    I just want to clarify that I cannot or can use javax.naming.event.EventContext with CORBA Naming Service.

    Can anyone tell me if it is doable or not doable.
    I looked at the COSNaming SPI, and it seems like it doesn't implement javax.naming.event.EventContext.
    Am I correct or not?

  • Problem starting Microsoft Forefront Server Protection Eventing Service?

    Hi Guys,
    Our Exchange 2007 Microsoft Exchange Information Store and Microsoft Exchange Transport services wont start. All dependencies have started except Microsoft Forefront Server Protection Eventing Service. We tried starting it manually but we got this message
    (see attached). Any idea how to fix this? Since we cant start Microsoft Exchange Information Store and Microsoft Exchange Transport services, OWA users cant access their emails. Please advise.
    Thanks,
    Arnel

    Hi Arnel,
    Based on your description, I understand that the Microsoft Forefront Server Protection Eventing Service can’t
    be started.
    Please run
    services.msc, select the Microsoft Forefront Server Protection Eventing Service and double-click to open it. In the service properties show box, please select Dependencies tab to check which service that it depends on didn’t start.
    Meanwhile, would you please let me know which version of the
    Forefront for Exchange Server? Please check if you have installed the latest updates to Forefront for Exchange Server. (Such as:
    Hotfix Rollup 3 for Microsoft Forefront Protection for Exchange and so on.)
    By the way, this issue seems to be more related to Forefront for Exchange Server. Please post it in the Forefront
    for Exchange Server forum. I believe we will get a better assistance there.

  • JApplet communication with CORBA naming service

    I have an applet that needs to resolve/bind to object in the CORBA naming service (we are using Orbix2000). The applet is able to establish a socket connection to the host that is running the naming service; however it cannot find the naming service. I have done extensive research on the web (followed the tutorials from the Sun site) and google to no avail. Can anyone shed some light? We have successfully used Orbix2000 with Java apps. This is the first access via an applet.

    Kat:
    I ran into a similar problem. I was wondering if it had anything to do with a security policy between the applet and CORBA, i.e., apllet using the NamingService. To test this, I built a another CORBA Java Client (character interface, not applet) and it works fine. The applet must require something else, like setting a security policy. I sent a query off to someone who manages the Java environment. If I get an answer, I'll post it here.

  • Customer Service Problems

    After fighting with Verizon customer service over two service issues without any possibility of resolution I am canceling my account. 
    I’m doing this reluctantly because as a long-term shareholder of Verizon I would like to see the company succeed and keep profitable.  Yet I am appalled by the cavalier, disrespectful, obstructionist treatment from your staff in dealing with customer service problems.  When you were just the telephone company and operated as a monopoly in a regulated industry, you had to take customer issues seriously.   Now that you are an unregulated telecommunications giant it seems that you don’t feel the need to respond to your customers.  Someone in your company needs to hear this and put a stop to these destructive business practices. 
    In brief, the first issue involved arranging a service call for interruption of internet service.  The entire process kept me on the phone for a total of 3 hours over several days.  I have given up my land line and use a cell phone exclusively.  Verizon’s communication systems and staffing levels caused me to wait on hold for 10-15 for each person that I spoke to. Then each conversation averaged 10 minutes.   In addition, I was transferred to different departments but  I did not understand the reason for the transfers.  Then the pattern of hold-talk-transfer began again.  Several times my calls were dropped necessitating more repeats of the hold-talk-transfer pattern.  Some of your staff were South Asian and they either garbled or misunderstood English, thus prolonging the conversation beyond the average of 10 minutes.    During that time I incurred cell phone charges of $.45/ minute.   
    After the service was restored I called Verizon customer service and asked for a service credit to compensate me for those out-of-pocket expenses over and above 30 minutes which I consider to be a reasonable amount of time to arrange a service call.  They denied any responsibility for the amount of time it took to arrange the service call or the amount of time to complain about their service.  I was not happy with the outcome so I requested to speak with someone who was a decision maker and had authority to negotiate a settlement.  I also asked to have them communicate with me through email.  I was told that communicating through email was not possible.  These calls followed the same pattern of hold-talk-transfer averaging 30 minutes each.  I repeated myself to 3 or 4 people who wrote down my complaint before I got to a manager who had decision making authority.  The manager denied any responsibility for the amount of time it took to arrange the service call and would not authorize a service credit.  
    The second issue involved billing.  I signed up for auto-pay to have my monthly bill deducted directly from my bank account.  Verizon’s computer system deducted the bill twice, overdrawing my account.  I incurred a bank overcharge fee.   The same pattern of hold-talk-transfer began for this complaint as well.  The customer service staff refused to take responsibility for this error as well.  Their solution required me to spend more time and incur extra expenses.  I had to repeat myself to 3 or 4 complaint takers before I reached the same manager who denied my first request.  He denied any responsibility for this billing problem too.    I had to have my bank retrieve the money under a fraud compliant.
    Verizon is one of the largest *communications* corporations in the world.  If your internal systems can't handle customer service calls in a reasonable amount of time, then there is a problem.  If your customer service staff is unwilling to take responsibility for such inadequacies and solve the issues that emerge from them, then there is a problem.  If a customer has to contact the CEO of the company to try to resolve two service related issues, then there is a problem.  When all of those actions prove inadequate, then there is a *communications* problem.
    Customer service has flagged my account and put me down as a “problem” customer.  Instead of offering even a token settlement, they are prepared to stonewall me by maintaining that the company is just not at fault and that they tried to solve the problems but I wouldn’t cooperate or accept their solutions.   Early on in the process, if someone told me that Verizon messed up just a little, but still couldn’t compensate me, I would have accepted that, albeit reluctantly, and dropped the matter.
    This is not the way I do business and I resent it when others don’t feel the need to honor any kind of code.  I grew up working in my family’s retail liquor store.  From the time I was a kid I learned four customer service lessons that I’ve carried over into my adult life:
    Admit when you are wrong and try to make up for the mistake.
    Never argue with a customer over small things.
    Listen to the compliant and don’t just dismiss it out-of-hand
    Try to make things right even though you may not be directly responsible for problem.
    For my two problems, Verizon customer service staff didn’t even come close to following these common sense rules.   I’ve learned that if you ask their customer service people they will repeat back to you some type of business code that they say they operate under.  But their behavior tells a different story.
    Unfortunately when I spoke with {edited for privacy} of the Executive Presidential Appeals office, I was taken somewhat aback by his manner and demeanor, which was coarse and inappropriate for a customer service discussion, and which I found personally offensive.  He and members of his staff agreed to send me emails specifying which part of the Terms of Service they based their decisions on.  To date I have not received the communications they promised.
    Is this the image of your company that you want the public to see? Are you willing to just shrug off these complaints as an isolated case that is too small to concern yourself about?  I’m afraid the answer will be yes.  Not only do you feel that you are too big to fail, but you are too big to care.   Customer service means solving problems not manufacturing bad will and resentment.  
    My purpose in writing this note has been twofold: to make one last effort to solve my problem and to hope that someone will take note about the issues about customer service practices that are harmful to the company. I'd be happy to speak with someone with real authority to deal
    with my issues but have no interest in repeating my past experiences.
    It's too bad that this had to happen since the solution could have been so easy and simple.
    I plan to publish some form of this letter and distribute it to the public. 
    Solved!
    Go to Solution.

    Therefore, I request to please clear this unacceptable due balance, and contact Experian to removed and clarified the mistake in my credit report. 
    RE:  Cancellation fee charged on internet DSL service charged by mistake. {edited for privacy}
    A $65 balance remain for a cancellation fee on internet DSL service, by Verizon New York mistake.
    In February of 2010, I set up my phone and TV in a vacation plan but keep my internet service active. After a month I had a vacation plan, suddenly without notification, my internet service was suspended and a cancellation fee was issued.
    My final statement was $ 24.47. I cleared a check from Verizon.
    I contacted Verizon online to request connect my internet service and discuss the issue on the cancellation fee. The response was that I should pay the internet cancellation fee, and paid a new activation.
    After fighting with Verizon customer service over the unacceptable fee charge service issue without any possibility of resolution I cancel my home phone which was in a vacation plan. 
     Later I kept receiving the statement with this cancellation fee every month. I called and discussed the issue more than 6 times during the next 6 months, The entire process kept me on the phone for a total of 2 hours over several months. The costumer representatives responded that the issue was in an investigation.
    Later,  a Collector company start chasing me to get the $65 paid. Phone number: {edited for privacy}, Inclusive, they made an offer to reduce the amount if I accept to pay or contact Verizon to request a clarification.
    By the end of the year, I contacted Verizon costumer services one more time but the representative stated that the account is not visible anymore.
    Convinced that the problem on this account was resolved, the second week of November, I called Verizon to reestablish my account with a new home phone number and Internet DSL connection.
    The answer was that  following Verizon policy I was unable to get a new account if a balance remain.
    After I explained the events, a manager (non-identified) who spoke to me by phone told me that Verizon will investigate the issue and I should wait for approval.
    On November 16, my account was confirmed approved and clear of debt, therefore, Verizon welcome me back with Home phone and internet DSL Service and confirmation on my online registration.
    New number:{edited for privacy} ; Email:{edited for privacy}
    Also, during the months of January and February 2010, Verizon New York, made other charges mistakes in my account (See details below) that have been resolved with an apologize and a refund.
    Events that prove the lack of training and support Verizon customer and billing service have.
    Chronology of the emails exchanged between Verizon Ecenter and myself after I requested investigation with the charges.

    2/08/10 Verizon eCenter responded. (Linnette) 'I apologize for the error'. 
    A credit for the international plan has been applied to your account and will appear on the next statement.'
    2/08/10 Verizon eCenter responded (Cheniqua) 'The regional essential calling plan does not qualify for a discount during vacation suspension. Which prove that my home phone was in a vacation plan.
     2/15/10 I have contacted Verizon customer support in regard of a non-notified, neither requested suddenly suspension on my internet DSL service and charged a cancellation fee for this suspension.
    Tracking # {edited for privacy}
    2/16/10 Verizon eCenter responded (Michael)  I am sorry for the inconvenience you have experienced. 
    Please contact our Consumer Sales and Solutions Center directly at 1-800-Verizon or (800) 837-4966 
    Monday through Friday between 8:00 AM to 6:00 PM Local Time. 
    2/16/10 Verizon eCenter (Sue)  responded : I am sorry for the inconvenience you have experienced. 
    I understand your frustration and concern regarding canceling your internet service in error. In order to provide you with the best customer service, please contact our Consumer DSL Sales and Solutions department directly at (800) 567-6789 and a representative will be happy to assist you.
    I stand on my decision of not pay for someone else mistakes.

    Without doubt after this problem get clearly resolved, you will lose this good costumer, get a negative feedback and I am planning to publish this letter at every web forum available.

  • Webcenter Spaces Events Service configuration: FATAL Alert BAD CERTIFICATE

    Hello,
    I have a simple requirement to connect the events taskflow from an exchange server that is https and has a confirmed security certificate. I use the wsdl path for the events service and add it to my webcenter spaces service configuration -> Personal Events configuration.
    Then I ran into this error.
    javax.net.ssl.SSLKeyException: FATAL Alert:BAD_CERTIFICATE - A corrupt or unuseable certificate was received.
    So, I downloaded the .crt file from Chrome (in per format) and used the keytool to upload the certificate exception into the cacerts file inside jdk and jrocket folders. I restart the managed server running WebCenter Spaces. This had no effect on the error.
    Is there anything else that I should do?
    Thanks,

    Hello Sibasish,
    Did you start the DI Event Server in the server?
    Start=>Run the command "services.msc"=>Start the DI Event Server.
    From its architecture, the landscape is:
    1. Server
    -B1DIEvnetServer - It is a windows service application called u201CSAP Business One DI Event Serviceu201D that create the remoting
    <<C:\Program Files\SAP\SAP Business One DI Event Service\SAP Business One DI Event Server\B1DIEventsServerService>>
    2.Client
    -B1DIEventService <<C:\Program Files\SAP\SAP Business One DI Event Service\SAP Business One DI Event Client\B1DIEventsService>>
    The B1DIEventService is a library that both client and server must compile with (nothing to be changed by the partner). It acts as a filter taking simple commands from the client application and implementing the technical part of the connection with the B1DIEventServer.
    The log in your last post is for this component in client.
    -Partner AddOn
    The name B1DIEvnetServer and B1DIEventService is somehow confused.
    Have you tried the client sample?<<D:\08-Perforce\BUSMB_B1\SBO_Tools\dev\Tools\SDK\B1DIEventsService\ClientSamples\ClientSampleCSharp>>

  • Some questions about eDirectory event service.

    Hello Everyone,
    I did a collector application which is based on eDirectory event
    service and Novell LDAP library for Java. We use it to monitor events
    and fetch logs of activities inside the server.
    The question is that some events defined in event system can not be
    captured, such as EVT_MOVE_SUBTREE, EVT_DELETE_SUBTREE, and
    EVT_VERIFY_PASS etc.
    Who can I resolve this problem? is it a bug of Novell eDirectory
    event service? My feeling is that event service is not stable.
    Thanks,
    Alex

  • DI Events Service over several SAP Databases

    I have a problem with DI Events Services. I am developing an application that makes use of  DI Events Service, in the documentation of the application says that you can make use of it to notification events in multiple databases, simply instantiating
    B1DIEventsService object for each SAP database. At the time of the second instance and run the Connect method
    I get "already signed the TCP channel", I wonder if the applications have this functionality and that way you can implement this
    change.

  • Can't re-add printer after removing from eprint center - 'Web Services Problem'

    I have an HP Photosmart Premium C310 series printer (Model Number CN503B) which I have been using with ePrint for about 18 months. Aside from intermittent issues it has worked, I use a chromebook most of the time so rely on the ePrint option via Google Cloud Print.
    Last week it stopped working, with every job in the list showing as cancelled. Following advice on the forum I removed the email address of the printer from the eprint center. I thought it would then be simple to add the printer back. However, I have been unable to connect the printer to the web service so I cannot create the code I need to add the printer back.
    STEPS TO REPRODUCE:
    1. Factory reset printer settings
    2. Factory reset network settings
    3. Restart printer and Reboot router
    3. Settings -> Network -> Wireless Setup Wizard
    4. Choose correct SSID, enter password for WPA
    5. ‘Connected to Network’
    6. Settings -> Web -> Enable Web Services
    7. ‘Accept terms’ screen -> Accept
    8. ‘Checking for product updates’ screen shows briefly then returns to 'accept terms' screen
    9. Next it makes a ping sound and shows ‘Web Services Problem’ ‘Problem connecting to Web Services Server’, it then pings again a few seconds later (which ties in with what I see in the network logs as a second attempt)
    10. Log on to printer via web interface and set IP address of printer to manual IP outside DHCP range (as advice on other threads in this forum). Check DNS setting valid (same as gateway server which all other devices on network are also using successfully as DNS)
    11. Repeat steps 6 and 7 - still same error message
    I consider myself technically savvy and have followed all advice I can find on this forum including the following:
    1. reverting to printer and network defaults
    2. rebooting router
    3. assigning static IP address to printer outside of DHCP range of router
    4. connecting to printer via web interface and setting DNS to variously: same as gateway, google DNS (8.8.8.8), ISP DNS
    5. adjusting firewall settings on router to explicitly allow and log outbound connection on the HP ports (already had a rule allowing all outbound connections)
    As mentioned, the printer worked fine with ePrint previously so I suspect the ePrint server is rejecting a request from my printer for some reason, maybe because there is old / corrupt  data on the server regarding my specific printer.
    I’m logging outbound traffic from the printer and here are what the router logs show me (printer IP replaced with 192.168.x.x below, even though it is not public )
    Thu, 2013-04-11 09:13:42 - TCP Packet - Source:192.168.x.x, 36475 Destination:15.201.202.81,80 - [HTTP rule match]

    Looks like both are HP sites: first is 'g4t2674.houston.hp.com' and the second secure one is ‘registration-pro-site2eprint.houston.hp.com’ which sound likely to be correct. That suggests the DNS is working but that the registration server doesn’t like the request for some reason.
    I had the printer registered for Google Cloud Print but I have now deleted that also and it doesn’t seem to have made any difference (assume it just formats and forwards to the HP ePrint email anyway).
    One hack that sheds some further light is to switch off wifi on the printer and then switch on ePrint. Eprint gives an error but stays set as 'on'. When I then switch wifi back on I can then at least check for product updates (it tells me I have the latest product updates). However, web services are still a 'no go'. Network traffic for that product update exchange looks like this:

    So clearly the printer can communicate to those servers well enough to find it has the latest firmware. 
    I realise this is a lot of information but hopefully some of it is helpful for troubleshooting.
    Thank you in advance for any help!

    The issue disappeared this weekend. I didn't change anything so it must have been something server side. I notice others with the same issue have also seen it resolved.
    Thanks to all those who contributed and tried to help out. Although disappointed I went for a long time without ePrint I'm glad that action was apparently taken to resolve in the end.

  • File Proxy Service Problem on errors

    In continuation of this thread...
    File Proxy Service Problem on errors
    We are now facing two problems.
    1.The proxy service is executed twice
    2.File is getting moved to error directory with prefixed file names which we are not able to retrieve and use in the notification email.
    Not sure how to fix :(

    1.The proxy service is executed twice Check if this is due to transaction timeout issue as discussed here. Re: OSB File polling working twice with the same file
    2.File is getting moved to error directory with prefixed file names which we are not able to retrieve and use in the notification email.I am not sure wehther you have any option here. You can check with support. Alternatively can raise notification mail with the timestamp and some file/business identifier from the file. The support person can then open the file from error directory to verify the file/business id in the file or educate the support user that the files will have a prefix

  • GUI event handling problems appear in 1.4.1 vs. 1.3.1?

    Hi,
    Has anyone else experienced strange event handling problems when migrating from 1.3.1 to 1.4.1? My GUI applications that make use of Swing's AbstractTableModel suddenly don't track mouse and selection events quickly anymore. Formerly zippy tables are now very unresponsive to user interactions.
    I've run the code through JProbe under both 1.3 and 1.4 and see no differences in the profiles, yet the 1.4.1 version is virtually unusable. I had hoped that JProbe would show me that some low-level event-handling related or drawing method was getting wailed on in 1.4, but that was not the case.
    My only guess is that the existing installation of 1.3.1 is interfering with the 1.4.1 installation is some way. Any thoughts on that before I trash the 1.3.1 installation (which I'm slightly reluctant to do)?
    My platform is Windows XP Pro on a 2GHz P4 with 1GB RAM.
    Here's my test case:
    import javax.swing.table.AbstractTableModel;
    import javax.swing.*;
    import java.awt.*;
    public class VerySimpleTableModel extends AbstractTableModel
    private int d_rows = 0;
    private int d_cols = 0;
    private String[][] d_data = null;
    public VerySimpleTableModel(int rows,int cols)
    System.err.println("Creating table of size [" + rows + "," + cols +
    d_rows = rows;
    d_cols = cols;
    d_data = new String[d_rows][d_cols];
    int r = 0;
    while (r < d_rows){
    int c = 0;
    while (c < d_cols){
    d_data[r][c] = new String("[" + r + "," + c + "]");
    c++;
    r++;
    System.err.println("Done.");
    public int getRowCount()
    return d_rows;
    public int getColumnCount()
    return d_cols;
    public Object getValueAt(int rowIndex, int columnIndex)
    return d_data[rowIndex][columnIndex];
    public static void main(String[] args)
    System.err.println( "1.4..." );
    JFrame window = new JFrame();
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel panel = new JPanel();
    Dimension size = new Dimension(500,500);
    panel.setMinimumSize(size);
    panel.setMaximumSize(size);
    JTable table = new JTable(new VerySimpleTableModel(40,5));
    panel.add(table);
    window.getContentPane().add(panel);
    window.setSize(new Dimension(600,800));
    window.validate();
    window.setVisible(true);
    Thanks in advance!!

    Hi,
    I've fixed the problem by upgrading to 1.4.1_02. I was on 1.4.1_01.
    I did further narrow down the symptoms more. It seemed the further the distance from the previous mouse click, the longer it would take for the table row to highlight. So, clicking on row 1, then 2, was much faster than clicking on row 1, then row 40.
    If no one else has seen this problem -- good! I wouldn't wish the tremendous waste of time I've had on anyone!

  • Urgent web service problem. can not find url of WSDL

    Hi all,
    I met a web service problem recently.
    1 I have set up a web service and reside it on Java System Application server9.0. But there's a bug of this web server, which will stop after the user log off the server. I have installed the Application server as a windows service. It suppose to run all the time. I don't know why the server stop after I log off.
    2 For that reason, I tried to migrant my web service from the java application server to Tomcat5.5. I deployed my web service to folder webApps. But I don't know the WSDL url of the web service, which is the web reference for my frent-end c#.net application.
    Anybody can give me some idea?
    Many thanks

    Nobody knows?
    Please help me
