How do i meet a client?

am new here and i need a pal

Why do you need to identify the client? Do you need to hold some conversational state between calls? If so then just use stateful session beans. However if you just need the identity for auditing purposes then having multiple clients with the same credentials seems like bad design to me. If several clients use the same user, your system shouldn't have to care how to distinguish them. They are the same. However if you want several users with their own identities and the same rights, add them to the same role, but create separate credentials for them.
The only object holding data about the logged in user will be the Principal which I guess you already found in the SessionContext. (SessionContext#getCallerPrincipal()) Since some ejbs are stateless I don't understand why you would expect them to have some sort of session mechanism going on during the calls.

    Though you can initiate the binary from your client side but for the file creation, there is no other way but to store it on the server side. So your best bet would be to get some space free on the server side of yours.

  • How to send meeting invites using Exchange Email Account

    Does anybody know how to send meeting invitations using the 3.0 software update?
    My corporate email is set up with an Exchange ActiveSync account, but I can't figure out how to send meeting invites?
    Is it a function solely of the iPhone 3.0 OS, or is it dependent on the Exchange setup.
    Any insight would be appreciated.

    That is what I was afraid of...the good thing is that is the only feature (besides battery life) that I miss from my Blackberry. Thanks.

  • How can I know which clients are connected to my network through express and which are connected through extreme?

    I have an airport express extending, through wireless, a network provided by an airport extreme. How can I know which clients are connected to my network through express and which are connected through extreme?
    Here you can see both routers:
    I would expect to some clients connected to the express, other than the extreme. And that's all I see: only the airport extreme appears as client of the airport express.
    Below, one can see the summary of the config for both routers.
    Would somebody explain it?

  • How to upgrade the Oracle Client silently ?

    Hi all,
    I have to upgrade the Oracle Client from 8.1.6.0.0 to 9.2.0.1.0.
    I use the -record option for creating the destination file or edit the response file manually for being able to install the new client. But I have no idea, how to remove the old client.
    The following command doesn't work:
    C:\Program Files\Oracle\oui\install\setup.exe" -deinstall DEINSTALL_LIST={"oracle.client","8.1.6.0.0"}
    What am I doing wrong? How to remove the Oracle Client silently?
    Thanks for the help and best wishes from Frankfurt.
    Dimitri

    I created a instant client silent DE-INSTALL for version 10.1.0.2 on XP.
    setup.exe -silent -deinstall -responseFile Z:\yyyyyy\xxxxxx.rsp
    These are parameters are in my response file...
    ORACLE_HOME="C:\oracle\InstantClient\10.1.0"
    ORACLE_HOME_NAME="OraInstantClient10g_home1"
    TOPLEVEL_COMPONENT={"oracle.client","10.1.0.2.0"}
    DEINSTALL_LIST={"oracle.client","10.1.0.2.0"}
    SHOW_SPLASH_SCREEN=false
    SHOW_WELCOME_PAGE=false
    SHOW_END_SESSION_PAGE=false
    SHOW_EXIT_CONFIRMATION=false
    SHOW_DEINSTALL_CONFIRMATION=false
    SHOW_DEINSTALL_PROGRESS=true
    REMOVE_HOMES={"c:\oracle\ora81","c:\oracle\InstantClient\10.1.0"}
    You still have to manually update/remove the PATH & TNS_ADMIN environment variables and the file system directories.

  • How to get the loaded client sequence file path/name?

    I added a step in Process model, and wanted to get currently loaded client sequence file name/path. I used the variable of "SequenceFile.Path" but then I realized what I would get is the process model file path, not loaded client sequence file path/name. How can I get loaded client sequence file path/name?
    Thanks!
    Jacky

    I dont understand what you are trying to achieve.  Can you provide more information.
    If you are trying to dynamically load and run a client sequence file at run time you need to make a couple of calls to the TS API from inside the process model, Engine.GetSequenceFileEx to get a reference to your sequence identified by its pathname, and then Execution.ClientFile to tell the process model which sequence you want to run.

  • How to use remote desktop client in mountain lion

    How to use remote desktop client in mountain lion.
    I want to connect my other system(ubuntu) using mac remote desktop client, But i could not locate remote desktop client in moutain lion.

    In Ubuntu 12.xx use Dash to find "Desktop Sharing" and set the preferences, including requiring a password.
    Then in Ubu use System Settings > Network to determine your Ubu machine's IP address, such as 192.168.1.13.
    On the Mountain Lion Mac do Finder > Go > Connect to Server   and enter:  vnc://192.168.1.13  or whatever your IP is.  Enter the password that you used in the Ubu Desktop Sharing setup, when asked.
    On the Ubu machine answer the question that pops up asking for permission to connect.  Your Ubu screen will now show up on the Mac, and you can remote control it.   Here I am running "Octave" (a math program) on the Ubu machine, remotely.
    Works great!  BTW, you can do this from an iPad too, using a VNC client such as Mocha VNC Lite.  You can even run both remotes simultaneously.
    Good luck.

  • Changed IP address, how do I update the clients

    I've poked around but all I can find is info about how to change the IP address of a TC without additional information about what to do with existing clients.
    I'm not using a TC in this case (NAS frontended by a Mini providing AFP accesss), but I figured this would be the best place to ask.
    I set up TimeMachine on most of our Macs (all 10.7 and 10.8) a few weeks ago, but just had to reconfigure my network which neccesitated changing the IP address of the host that provides the TM remote disks.
    How do I tell the clients to start using the new address of the server? Will just adding a new disk do the right thing (I haven't tried as I don't want it to clobber what already exists).
    Thanks.

    Yes, you have to change the setup in each computer to redirect it to the new location of the backup disk..
    You can do a TM reset.. but that should not actually be necessary.
    See A4 here. http://pondini.org/TM/Troubleshooting.html
    But TM is smart enough that when it finds the disk.. it will then find its previous backups and continue the backup .. after suitable verification. You can change the computer name. Change the disk name. Change the backup sparsebundle name.. TM will still find it and continue to use it. And even if there are multiple sparsebundles or disks with the same name or even computers with the same name.. which would break network rules,, but TM still won't get confused.
    Again read up a bit of how TM works its magic.
    http://pondini.org/TM/Works.html
    The UUID is picked up from source hard disk I guess.. and that is what is used. This ensures everything is kept separate from names or even IP address.

  • How to startup DB in client?

    Hi there,
    How to startup DB in client?
    SQL> conn scott/tiger@mytestdb  as sysdba
    Connected.
    SQL> shutdown immediate
    Database closed.
    Database dismounted.
    ORACLE instance shut down.
    SQL> startup
    ORACLE instance started.
    ORA-12528: Message 12528 not found;  product=RDBMS; facility=ORAI used all default setting when creating DB.
    What other setting is needed?

    You have 2 problems:
    1) ORACLE_HOME not set as environment variable (you don't see a real error message)
    2) dynamic service registration with the listener
    Error is:
    Error:     ORA-12528 (TNS-12528)
    Text:     TNS:listener: all appropriate instances are blocking new
         connections
    That means , listener does not know the service, because there's no one defined statically in your listener.ora . Dynamic registration requires an open database.
    By the way in my opinion it's not a good idea to grant user scott the sysdba privilege.

  • How to debug a Mobile client application

    Hi,
    How to debug a mobile client application on the laptop, where we dont have any .NET 2003 application installed. (not an MDW)
    If we get any error on the application, which could be a UI error on laptop, and if everything is working fine on the MDW, is there any way to debug the application on Mobile client?
    Also, please provide me links or tips on how to debug the mobile application, on MDW as well.
    Regards,
    Praveen.

    Hi,
    to be able to debug on a local machine you would need at least to install the UI/BOL class files and the project files and make some local settings.
    But anyway on all clients there should be the same MSA installation like it is on the MDW so in case of an issue it is normally caused by local (inconsistent) data.
    I would suggest to access the laptop IDES database by changing your MDW odbc settings and perform the debug session on the MDW.
    Debugging in VB .net is similar to VB6 but you have to notice that changing of the code is NOT possible when being in debug mode.
    Regards,

  • How can I add a client wireless usig Airport Utility 6.0?

    In menu airport of firmware 6.0 there is not window "Add a wireless client". I'm using Mac Os lion with Airport Utility6.0, how can I add a client wireless with this firmware)?

    If you have a dual band AirPort Extreme, you can add another to "extend" both bands of your network to provide more  wireless coverage.
    The "best" way to do this is to connect the "remote" access point back to your main AirPort Extreme using an Ethernet connection. This preserves bandwidth on the network better than any other method...and...you can locate the "remote" Extreme exactly in the area where more coverage is needed. Instructions for thhis are here:
    http://support.apple.com/kb/HT4260
    You might be able to connect using wireless only, but this is always "Iffy".
    In general, the Extreme would need to be located approximately half the distance from your main router to the general area that needs more coverage. But, walls, ceilings and other obstructions usually come into play, requiring some experimentation. Instructions are here:
    http://support.apple.com/kb/HT4259
    If you elect to try wireless, you really won't know if things will work until you try. Recommend that you have a "Plan B" if wireless does not work for your purpose.
