Session storage between Java and PL/SQL

Hi all,
We have made Java servlet using session storage. The data stored is valid until session is changed. Seems that session is changed during logon or even if web page (where the servlet is located) is refreshed!
PL/SQL doesn't lost the session storage data during logon. But is it possible to find Java session storage from PL/SQL session storage?
Java session storage doesn't use domain name or subdomain which are mandatory for PL/SQL session storage.
Portal version is 3.0.9.8.5
Thanks,
Jari

  • Using session storage between Report and Frame Driver

    I have an existing report that has a link calling a frame driver with multiple forms. I would like to make the Initial Target Frame Content dynamic based on information contained in the targeted record of the report. I am able to make this work (in basic concept) on the frame driver side, but have not been able to pass session variables from the report side. I can, of course, pass bind variables via a link from the report. Does anyone know of a way to access the parameter bind varaiables in the frame driver component using session storage or something else in order to make these variables available to the PL/Sql of the Initial Target Frame?

    Seems that session is changed during logon or even if
    web page (where the servlet is located) is refreshed!In Portal 10g (and maybe even in 9.0.2.6) the Web provider session is not lost any more when the user logs in to Portal.
    PL/SQL doesn't lost the session storage data during
    logon. But is it possible to find Java session storage
    from PL/SQL session storage?No, you cannot share the session between database and Web providers. You need to find other ways to share information between portlets belonging to different providers. You can use parameter passing, or a persistent store, such as the database.
    Java session storage doesn't use domain name or
    subdomain which are mandatory for PL/SQL session
    storage.The domain, sub-domain strings are irrelevant, as long as you can uniquely identify your session variable. For example, if you want to make sure that you have a separate session variable for every portlet instance, you should include the preference path in your domain or sub-domain. In case you want to share the session store between your portlets, don't include the unique portlet ID.

    Doesn't the following link give you enough information?

    Anyway .. This error means that the given ResultSet column index which you're trying to retrieve the value from is out of the range.

    I am getting the following error message when I am trying to test the connection between JAVA and ABAP systems.
    1. The system ID is valid
    2. The system was retrieved.
    3. The system object represents an SAP system
    4. The following parameters are valid: Web AS Protocol (http) Web AS Host Name (s09f71v06.svr.bankone.net:8100)

    6. The server s09f71v06.svr.bankone.net *could not be pinged* successfully.
    I have JAVA and ABAP on the same system. I am trying to establish a connection. I have checked all the settings and they looks fine. I have also pinged from other system to this server and the Ping works fine.
    Please do let m eknow where do I need to check for the errros or logs for the above error message.
    Appreciate your quick help.
    Mahesh

    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.

  • Data conversion for communication between Java and C/C++ program

    The real problem, i guess, is about data type conversion between Java and C programs. For instance, and int is supposed to be 4 bytes in Java, and also in C/C++. But, as far as I know, the size of and int in C depends on the processors architecture, so if it were a 64 bit arch., size of and int, double, etc. in C, would change. The real scenario would be a communication between a 32 bit machine (Java) and a 64 bit machine (C/C++).
    First of all, is this assumption correct?
    If so,
    how is it possible to deal with this problem in Java?
    Is there any way to know 'type length' automatically? or
    would it be necessary to modify the Java program to work with a C program in 32-bit or 64-bit arch?
    thx in advance

    Yes you should develop the C part of the protocol first and then build from there.
    See http://forum.java.sun.com/thread.jspa?threadID=5243547 for a previous discussion of this topic.
    I understand what you mean, also the topic you referenced. I will explain the situation a bit more. The protocol is already defined: (16 bits message size, 16 message id, 32 bit time, etc.); it is also defined in C (structures and so on). So it would be easy to write my Java code using the specified protocol in bytes, and C types wouldn't be necessary to be considered. But, let's say that the C code can't be modified, and I thought (and don't know yet if its correct), that size of C types CAN changed depending on architecture. So if size changes for C types (code is specified in short, int, etc, and not in bit format), it all would be a mess, if I don't implement something in my Java code.

    I don't believe that 32 or 64 bit enters the equation here at all.Maybe 32 o 64 doesn't mind, but sparc or PC could take a point here. Communication would be between a sun solaris sparc and windows x86 PC. But if type size in C/C++ does not change, I wouldn't really have any problem then...
    The situation is not ideal, I know, but is what I have; and I think I could have problems if I run the C program in other machines; so I would have to try to solve it whithin my Java Program.
    I hope it is clear now what I need.

  • Communication between java and c++, help!

    i am c++ programmer and newly to java.
    now i am developping a client/server app. i use java transfers data (socket) between client and server, and use c++ to create user interfaces because c++ is easier for interfaces.
    my question is:
    in a single PC, java needs to tell c++ what info was read from socket and c++ needs to tell java what info will be written to socket.
    i want to use 2 files (read and write) as media between java and c++. that is: java writes data to a file and c++ reads from the file, and vice versa.
    i know it's not efficient. could you tell me better way to do?
    thanks in advance.

    thanks for reply.
    my problem is: socket is fare in java, not fare in c++
    (win/nt). could u use server in a non nt-server
    machine with c++?I'm not sure what you mean "fair". NT-Server is just a version of NT that Microsoft adds their server products to. Most of which you don't want to use because they are a security nightmare. I think what your asking is can you do the equivalent of Java's ServerSocket in C++. Sure, the socket libraries in Windows (at least last time I checked) were based off the BSD socket libraries. So you would basically do something like:
    // Open socket
    ss=socket(AF_INET, SOCK_STREAM, 0);
    if(ss==-1)
      cerr<<"Error opening socket."<<endl;
      return 0;
    // Fill in address
    struct sockaddr_in server;
    server.sin_family=AF_INET;
    server.sin_port=htons((unsigned short)port);
    server.sin_addr.s_addr=INADDR_ANY;
    // Bind to port
    if(bind(ss, (struct sockaddr *)&server, sizeof(server))==-1)
      cerr<<"Could not bind to port "<<port<<"."<<endl;
      return 0;
    // Ready to accept connections
    if(listen(ss, 5)==-1)
      cerr<<"Could not listen."<<endl;
      return 0;
    // Loop to accept connections
    while(/* some condition */)
      // Accept a connection
      int s=accept(ss, 0, 0);
    }This should work on any version of windows as long as you have winsock. The example code might need to be changed a little though since I copied it from a Linux program I had.

    Do I need Java 8 or should I disable it? What happens if i disable it? And what is the difference between Java and Java Runtime?

    There's no difference. They're both runtime plug-ins (they run when an app calls for Java functions).
    You only need Java if you either have Java apps on your Mac that won't run without having it installed, or you use trusted web sites that require Java to function (getting fewer and far between). Otherwise, you have no need for it at all.

  • What are the Basic Differences between Oracle and  MS-SQL server Database?

    Hello,
            anybody pls Guide me about the Differences between Oracle and MS-SQL server Database.and also IBM Databases also
    Regards,
    Balaram

    SQL Server only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.
    In comparison with SQL Server , OracleDatabase supports all known platforms, including Windows-based platforms, AIX-Based Systems, Compaq Tru64 UNIX, HP 9000 Series HP-UX, Linux Intel, Sun Solaris and so on.
    The SQL Server  advantages:
    SQL Server  holds the top TPC-C performance and price/performance results.
    SQL Server  is generally accepted as easier to install, use and manage.
    The Oracle  Database advantages:
    Oracle  Database supports all known platforms, not only the Windows-based platforms.
    PL/SQL is more powerful language than T-SQL.
    More fine-tuning to the configuration can be done via start-up parameters.

  • Difference in event handling between Java and Java API

    could anyone list the differences between Java and java-API in event handling??
    thanks,
    cheers,
    Hiru

    the event handling mechanisms in java language
    features and API (java Application Programming
    Features)features .no library can work without a
    language and no language has event handling built in.
    I am trying to compare and contrast the event
    handling mechanisms in the language and library
    combinations such as java/ java API.
    all contributions are welcome!
    thanks
    cheersSorry, I'm still not getting it. I know what Java is, and I know what I think of when I hear API. (Application Programming Interface.) The API is the aggregation of all the classes and methods you can call in Java. If we agree on that, then the event handling mechanisms in Java and its API are one and the same.
    So what do you want to know?

    Hi Kemal,
    Hope you are doing good.
    There should be a / in the ITS path before SAP.
    Basically the entry that you have mentioned here should be accessible via browser as well. For eg in your case:
    http://<its hist name>/sap/bc/gui/sap/its/webgui should be accessible over browser.
    I also think you have put in a extra space in "w  ebgui". It should be "webgui".
    If the connector settings are working, then we can be sure that system connection is fine. You do not need to configure ITS settings.
    Also for SSO, refer the SAP note:1083421 and configure the SS0 settings again.
    Please run the SSO2 wizard and then make the automatic connection to
    the abap server. This will solve any inconsistencies on the server
    due to manual interventions.
    Most likely reason for the error is that certificates were loaded
    manually rather than using SSO wizard.
