Could not connect through rmi standalone client Oracle9iASR2 (Win2k)  !!

I have a standalone client which uses rmi to authenticate and call the EJBs. The client was able to use rmi under R1, however, after we migrat to R2, the rmi authenticate hangs forever.
What's the reason for this? Is there any configuration in order to call EJBs throught ormi?
Thanks for your help.

Hi Debu:
Thanks a lot for your information. I actually resolved this by change my ports to another range. So I even don't need specify a ormi port number there.
Now I have a new question. Do you know if we could authenticate inside an SessionBean using com.evermind.server.rmi.RMIInitialContextFactory ? I got an error when I tried to do that. The reason I want to do that is I deploy a session bean adaptor as WebService, but in Oracle9iASR2, to deploy as a secure web service, the authentication have to be done on a Java standalone client (Is this true?). Now my consumers of the WebService is a VB client. We don't know how to authenticate from a VB client. Therefore, I'm thinking, if I can authenticate inside the SessionBean Adaptor, that would resolve this problem.
Any idea on this? Thanks in advance.

    I am not sure what is your URL parameter in the getConnection Method !
    Check if the it is
    jdbc:oracle:thin:@<ip-Add of server>:<port no>:<SID>
    e.g.

    Hi Kanchan,
    So on each computer, you create a local user account that is a member of the Administrators group, and use the same account and password on each machine(controller and Agent), am I right?
    Could you enable the detailed log message?

  • Could not connect to remote service [rmi://localhost:1099/

    I have a large deployment with two filr appliances and one database and one search index.
    I am running zen load balancer in front of the appliance which works great.
    There are no config changes to the filr appliances in terms of port redirection.
    I had an issue upgrading from 1.0.1 to 1.1 so I blew it away and started fresh.
    After I installed and configured the appliances there were no issues . Now the :9443 configuration section will not work I get
    (this is just the top lines)
    HTTP ERROR 500
    Problem accessing /. Reason:
    Could not connect to remote service [rmi://localhost:1099/GangliaService]; nested exception is java.rmi.NoSuchObjectException: no such object in table

    at org.springframework.remoting.rmi.RmiClientIntercep tor.doInvoke(RmiClientInterceptor.java:347)
    This is on all appliances (search,data,filr1,filr2)
    I restarted filr2 and the admin section 9443 comes back for a short time. Maybe 10 minutes then I get the same error. But now after the restart I get and authentication box asking for credentials on 8443. when I put in the admin or other creds it directs me to a page that says
    HTTP Status 500 - Filter execution threw an exception
    type Exception report
    message Filter execution threw an exception

    I have rebooted to no avail. If I restart the jetty service I do get the appliance login for 9443 but if I try to login I get the same message about [rmi://localhost:1099/
    again if I reboot then 9443 works for 10 mins but 8443 gets hosed. Everything worked fine until I rebooted the appliance.
    I am afraid to even reboot these appliances now in fear that the will cease to work.
    I should also note that this was part of the upgrade issue I had after I rebooted all of the appliances.
    Thanks in advance.

  • Server 2008 TS - some client could not connect to the server

    Hi guys,
    I have a Server 2008 x64 Terminal Server with license server (some machine) and installed device CALs.
    I can connect with Windows 7 client to Terminal Server by RDP (TS assign device CAL to every connected machine automatically) without problem, but I get this error message if I try connection with Motorola (Symbol) MC8080 mobile scanners:
    "Because of a security error, the client could not connect to the remote computer.
    Very that you are logged on the network, and then try connecting again."
    I tried different settings by KB2477176 and activate/deactivate server, but it didn't solve the problem.
    http://support.microsoft.com/kb/2477176/hu
    (These scanners can connecto to another Terminal Server.)
    Is it client or server-side issue?
    Have you another idee?
    Regards,
    Gabor

    Hi,
    Thank you for posting in Windows Server Forum.
    Please again cross check whether you have properly configured certificate attached with the server. Because the error which you are facing is generally due to corrupted certificate on server side. As you have already tried, I again want you to back up the registry
    setting and then remove the X509 certificate registry key under below mention path, restart the computer and reactivate the RD Licensing Server. 
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM

    We have successfully configured network policy server on windows server 2012 and all wireless clients could connect to our network except windows 7 and xp non domain clients.The clients that are successfully authenticated includes windows 8,mobile users
    (andriod + iOS) domain as well as non domain clients.If we join windows 7 pc to the domain it  successfully connects but non domain clients could not connect.We have large number of windows 7 users that have their own laptop machines and we dont want

    On server event 6273 generated with reason code 265 "The certificate chain was issued by an authority that is not trusted".Plz help how to resolve this issue.I have searched on the internet but no proper solution found.

    Hi,
    According to the error message, it seems that you used certificate-based authentication methods and the non-domain computers has no Trusted Root Certificate for the CA that enrolled the certificate for the NPS.

  • After restarting i get a message saying that Windows could not connect to the Group policy client service

    The message i get is the following: 
    Windows could not connect to the Group policy client service. This problem prevents limited users from logging on to the system As and administrative user you can review the system event log for details why the service didn't respond.
    This happens after restarting my laptop. It takes longer than usual and once it has booted up and loaded Windows Vista, I get the message on the right bottom corner as a window popping up.
    I can still use my computer but a lot of my user account settings are not there.
    I fixed it temporarily by rebooting using the option: boot up using my last successful configuration. Bu once I restart again the same thing happens.
    How can i fix it?

    we have a client who has site hosted with us. They are using Contribute CS5 to connect to our web server and make changes to their site. They've been using Contribute for a month when all of a sudden they started receiving the error:
