Keep-alive connection between app and servlet

Hi,
I have searched the forum for information about how to keep a
connection alive between a client app and a servlet, but I have not been
able to find anything.
Does someone have an example of how to do this? Please send it!
Thanks!

HTTP connections are transient, they're not meant to be kept open.
HTTP 1.1 can support this feature, check the RFC and servlet specification (and probably the appserver documentation for configuration).
Best use another protocol though, ftp for example (or something else entirely).

  • Keep losing Connection between iTunes and Express

    I have Express, used exclusively to play music through powered speakers. However, my eMac and MacBook Pro iTunes keep losing connection to the Express. I have repeatedly reset the Express, get the connection back temporarily, then lose it again. I use a Netgear NEXT Wireless-N router and I do not see a setting that might solve this problem.
    Anyone have an answer? Should I set the router to have Express use a particular Port?

    Okay guys, I've got it with the help of Michael at Apple tech support (great customer service experience today--thanks Apple): It took some time to diagnosis the problem, but the solution we found was that it was actually two problems relating to interference:
    1. Change the channel: The network (changed it in Time Capsule as the AE is connected to that network) channel was set to 6, which is a common one that many routers default to. We set it to 9 and that improved it a lot, but not all the way, and he suggested trying some other channels to find the channel with the least interference in the area.
    2. Cordless 2.4 GHz cordless phone: We unplugged it and it's seemed to solve the interference problem almost perfectly (it's just cutting out for a second here and there every few minutes--compared to before for several minutes and only playing for a few seconds). He suggested getting a 6.0 GHz phone to bypass the interference, which is likely what I'll do. I'll also try relocating the phones base station and see if that makes any difference. Either way, after several hours of trying to figure it out it's nice to be listening to my music!
    If I find out anything else I'll post it here.

  • How is it best to keep files synced between iMac and Macbook?  I work from home on my iMac and then out in meetings on my Macbook and need to have access to the same files on both.

    How is it best to keep files synced between iMac and Macbook?  I work from home on my iMac and then out in meetings on my Macbook and need to have access to the same files on both.  The folders are using Microsoft programmes as this is compatiable with 90% of my colleagues, therefore I can't use the Icloud service.

    No, the camera connection kit only supports the copying of photos and videos to the Photos app, it doesn't support copying content off the iPad. For your second camera instead of the SD reader part of the kit, does the iPad to camera cable not work with it for direct transfer to the iPad ?
    For Lightroom and Nikon software again no - you can only install apps that are available in the iTunes app store on your computer and the App Store app on the iPad, 'normal' PC and Mac (OS X) software are not compatible with the iPad (iOS). There are some apps that perform fairly basic editing functions that are available in the store, but nothing as sophisticated as, for example, Lightroom.

  • How can I get connection between VC and back end ABAP system

    Hi, I'm developing the kits in the VC platform, and I need to access the back end system designed by ABAP. For example, the system provides some public functions(not web services), and I hope when I click the "search" button, the VC front can call the remote functions and get the data from the back end system. In addition to that, the most important is I must keep the connection real-time. How can I do it?

    Thanks for your help. At present, my VC version is 7.1.4 which isn't installed in the portal server but in local machine, and I'm new in the VC. What I want is when I click the "search" button(in the properties pannel), I can get the data from the remote server. I know the VC 6 provides similar functions, but the current version doesn't. Could you explain the details of how to get and keep the connection between them? Thanks so much.

  • Handoff: No connection between iPad and iPhone

    Handoff: No connection between iPad and iPhone (IOS 8).

    Hi raydela,
    I understand your calls aren't being transferred between devices.
    Check out the troubleshooting in this article.
    Get help using Continuity with iOS 8
    If a call doesn't transfer to your other devices, or you don't see the Handoff icons
    Make sure that your devices are using iOS 8 or later by going to Settings > General > Software Update.
    Check your settings:
    Go to Settings > Wi-Fi and turn on Wi-Fi if necessary.
    Go to Settings > Bluetooth and turn on Bluetooth if necessary.
    Make sure your iOS devices are connected to the same Wi-Fi network by going to Settings > Wi-Fi and comparing the name of the network each is on.
    Go to Settings > General > Handoff & Suggested Apps and turn on Handoff.
    Go to Settings > Phone and turn off Wi-Fi Calling.

  • Heterogeneous connection between Oracle and Postgres.

    Hi All,
    I'm trying to make an heterogeneous connection between Oracle and Postgres since few days but i still having this error : "lost RPC connection".
    First of all : I'm using Windows 7, Oracle 10g and PostgreSQL 8.4.
    I have done the following operations :
    1) Create a System DNS named "PG". (Test connection is OK)
    2) Create the file "initPG.ora" in "$ORACLE_HOME/hs/admin" :
    # This is a sample agent init file that contains the HS parameters that are
    # needed for an ODBC Agent.
    # HS init parameters
    HS_FDS_CONNECT_INFO = PG
    HS_FDS_TRACE_LEVEL = ON
    # Environment variables required for the non-Oracle system
    #set <envvar>=<value>
    3) Configure the file "listener.ora" (in "$ORACLE_HOME/NETWORK/ADMIN") :
    SID_LIST_LISTENER =
    (SID_LIST =
         (SID_DESC =
    (SID_NAME = PLSExtProc)
    (ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
    (PROGRAM = extproc)
    (SID_DESC =
    (SID_NAME = CLRExtProc)
    (ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
    (PROGRAM = extproc)
         (SID_DESC =
    (SID_NAME = PG)
    (ORACLE_HOME = C:\oraclexe\app\oracle\product\10.2.0\server)
    (PROGRAM = hsodbc)
    LISTENER =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
         (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
    (ADDRESS = (PROTOCOL = TCP)(HOST = Cédric-PC)(PORT = 1521))
    DEFAULT_SERVICE_LISTENER = (XE)
    4) Configure the file "tnsnames.ora" (in "$ORACLE_HOME/NETWORK/ADMIN") :
    XE =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = Cédric-PC)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = XE)
    PG =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = tcp)(HOST = Cédric-PC)(PORT = 1521))
    (CONNECT_DATA =
    (SERVICE_NAME = PG)
    (HS = OK)
    EXTPROC_CONNECTION_DATA =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
    (CONNECT_DATA =
    (SID = PLSExtProc)
    (PRESENTATION = RO)
    ORACLR_CONNECTION_DATA =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))
    (CONNECT_DATA =
    (SID = CLRExtProc)
    (PRESENTATION = RO)
    5) Finally, i create my DB-Link and test it :
    CREATE DATABASE LINK "CENTRALE_POSTGRES" CONNECT TO "user_login" IDENTIFIED BY "user_password" USING 'PG';
    SELECT * FROM "dual"@CENTRALE_POSTGRES;
    I got this error :
    ORA-03135 : lost RPC connection.
    As you can see, i have activated the trace level (HS_FDS_TRACE_LEVEL = ON), but the directory "$ORACLE_HOME/NETWORK/trace" still empty.
    Any ideas ?
    Regards

    the tnsnames.ora alias PG is wrong - you need to have 2 closing brackets after the SERVICE_NAME so that HS=OK is outside of the CONNECT_DATA like:
    PG =
    <space>(DESCRIPTION =
    <space><space>(ADDRESS = (PROTOCOL = tcp)(HOST = Cédric-PC)(PORT = 1521))
    <space><space>(CONNECT_DATA =
    <space><space><space>(SERVICE_NAME = PG))
    <space><space>(HS = OK)
    <space>)
    Please be also aware HSODBC up to release 10.2 has been desupported since March 2008 and it was replaced by its follow up product DG4ODBC V11

  • Failed to communicate between MIDlet and Servlet

  • What is the difference between apps and applications?

    I have an application that I've been running on my older Mac. Now that I have a new MacBook Pro, I have to reinstall new software that is compatible. When I go to the vendor website I see an application I can download or a link to the Mac App Store. Is an application different than an app? When should you download them from a vendor website and when should you go to the app store? Do apps end up in the Launchpad and an application in your Applications folder? I can't seem to find information on what is the distinction. Are they actually two different things? Any help would be appreciated.

    No difference between apps and applications. If you download the app from the Apple AppsStore you have better security and a conveninet place to have all your downloads. Nothing wrong with downloading from a trusted developer though.
    EDIT: Yes they will either wind up in your Download folder as  a .dmg you will have to double-click on to install, or most app store apps will install to your Applications folder.

  • Connection between O and BP is missing

    Hi,
      When i check inconsistency for a user, i am getting " Connection between "O" and "BP" is missing. When i check the Org.unit in PPOSA_BBP, i could see no BP exists for that Org.unit where user is assigned. I have replicated the org.unit from HR system but yet the BP hasnt been generated. Can you please share your idea on this.
    Regards,
    Prasath J

    Hi Prasath,
    This might be because you need to assign the user to a Purchasing Organisation or a Purchasing Group. If the user do not have BP created then you can do this by using tcode USERS_GEN.
    Go to USERS_GEN and follow below steps :
    1. Select Create User From Existing SU01 user
    2. Enter the org id of the POrg or Pgroup under which you want to assign the user
    3. Select country and execute
    4. In next window one popup will occur, select Area Of User
    5. In next popup enter the user id
    6. Next select the user and click Ok.
    7. This will create a BP and CP for the user and assigns the BP to the Org id of the POrg or Pgroup.
    8. Now check the consistency of the user it will show all green.
    It might give you error like eMail id for BP XXXXX is missing if the SU01 profile of the user does not contain any user id but it is not critical.
    You can open the BP in BP tcode and enter the email id of the user.
    Let us know if it solves your issue.

  • Can someone please tell me a simple but effective method for burning a slideshow to DVD? Now that the connection between iPhoto and iDVD no longer exists, I can't figure out a way to get there with an acceptable quality result.

    Can someone please tell me a simple but effective method for burning a slideshow to DVD? Now that the connection between iPhoto and iDVD no longer exists, I can't figure out a way to get there with an acceptable quality result.

    Export the slideshow out of iPhoto as a QT movie file via the Export button in the lower toolbar.  Select Size = Medium or Large.
    Open iDVD, select a theme and drag the exported QT movie file into the open iDVD window being careful to avoid any drop zones.
    Follow this workflow to help assure the best qualty video DVD:
    Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image  menu option. This will separate the encoding process from the burn process. 
    To check the encoding mount the disk image, launch DVD Player and play it.  If it plays OK with DVD Player the encoding is good.
    Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality.  Always use top quality media:  Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
    If iDVD was not preinstalled on your Mac you'll have to obtain it by purchasing a copy of the iLife 09 disk from a 3rd party retailier like Amazon.com: ilife 09: Software or eBay.com.  Why, because iDVD (and iWeb) was discontinued by Apple over a year ago. 
    Why iLife 09 instead of 11?
    If you have to purchase an iLife disc in order to obtain the iDVD application remember that the iLife 11 disc only provides  themes from iDVD 5-7.  The Software Update no longer installs the earlier themes when starting from the iLIfe 11 disk nor do any of the iDVD 7 updaters available from the Apple Downloads website contain them. 
    Currently the only sure fire way to get all themes is to start with the iLife 09 disc:
    This shows the iDVD contents in the iLife 09 disc via Pacifist:
    You then can upgrade from iDVD 7.0.3 to iDVD 7.1.2 via the updaters at the Apple Downloads webpage.

    Check the relevant services are test are active on the Backend system through SICF trransaction.
    Also make sure that default icm services are running.See note 517484.
    More important the connector test in the portal system should work properly,recheck the WAS path etc are correct.
