Problem when change DBF connection

I use jdbc dbf driver to connect to DBF.
String databaseDriverName ="com.hxtt.sql.dbf.DBFDriver";
Class.forName(databaseDriverName).newInstance();
String databaseDirectory=dbase;/
String url = "jdbc:DBF:///"+databaseDirectory;
java.sql.Connection con = DriverManager.getConnection(url,"","");
databaseDirectory is the path to DBF file
I transfer data from DBF to oracle database. When transfer is complete I close the frame, copy new file with same name on same location.
Frame is open again and i read the data from old file.
Where is the problem?

Even I have the same question... where is the problem? Looks like you have missed out the real part.

    dovdov2,
    are you saying that when you connect your MacBook Pro to a monitor, your Internet connection slows down, but when you disconnect the monitor, it speeds up again, and that this is reproducible from one day to another?
    Does this happen both under OS X and under Windows 7, or only under one of them?
    How are you currently connecting your MacBook Pro to your monitor?

  • Problem when changing connection to SQL Anywhere during runtime

    I designed a report in the Crystal Reports 2008 designer using a JDBC connection
    to a SQL Anywhere 11.0.1 database.
    Everything works fine, I´m able to preview the report in the designer.
    But when loading and running the same report in a Eclipse-based java-application I receive
    an error.
    When I set the db connection parameters I receive an "unexpected database-connector-error".
    When starting the report without changing the connection parameters set in the CR2008-designer
    the same error appears.
    When using a report based on a MySQL-database everything works fine.
    I´m able to preview the report in the designer and I´m able to load the report
    and change the datasource to another MySQL-database at runtime.
    What do I have to do to change a SQL Anywhere connection at runtime?

    Your workflow and the specific method being invoked where you're getting the exception is unclear.
    Sincerely,
    Ted Ueda

  • Error when changing database connection

    I changed my connections.properties file to a database other than the one I used to develop my application. I was able to connect to the new database successfully from the application but when I tried to insert a new row I received the following error:
    JBO-26041: Failed to post data to database during "Insert". SQL Statement "BEGIN INSERT INTO ITEMS (ITEM_ID, ITEM_STATUS, CATEGORY, SOURCE_TYPE, IMAGE_TYPE) VALUES (:1,:2,:3,:4,:5) RETURNING ITEM_ID INTO :6; END;".
    ORA-06550: line 1, column 102: PLS-00103: Encountered the symbol "RETURNING" when expecting one of the following...
    Does anyone know what is causing this problem?
    Thanks,

    Your new database connection must be pointing to an older database which doesn't support the returning clause. I believe this was added in the 8.x series.

  • Problem when changing the target quantity for a contract

    Hello,
    I have a problem when i try to change the target quantity for a contract through the BAPI 'BAPI_CONTRACT_CHANGE'.
    I filled the tables 'item' and 'itemx' with new values. the BAPI 'BAPI_CONTRACT_CHANGE' returns no error, but after using the BAPI 'BAPI_TRANSACTION_COMMIT' I get an info message from SAP and the modification does not pass.
    In debugger I could locate the error. In fact, the appeal of FM 'ME_UPDATE_DOCUMENT is done with a table XEKKN with the new values of the quantity and a KZ code equal to ' I ' to insert, then it must have the value ' U 'for update .
    Is someone can help me to solve this problem?
    Thank you in advance.

    Have you tried selecting the page, and then changing the theme directly on that page?

  • Problems when trying to connect BW to R/3

    hello all,
    i am new to SAP and am trying to connect my BW3.0 with R/3 4.6c which are on two different laptops. have created a logical source system on R/3 side and assigned it there successfully. have also created a logical system on BW side but when trying to assign it, i am getting an error 'be careful when trying to change the source systems'. have accepted it and after that i cannot go into RSA1- comes up with a message saying 'logical system has been changed'.
    when i go into details of this error message, it will ask me to delete all the transfer structures/rules created earlier and shouldnt be using ALE or work-flow.
    how can i assign the newly created logical system in BW???
    thanks in advance...
    sujan

    hello naveen,
    i will try to explain it again....
    i have already got a source system by name BWINST in my BW system and i have created another logical source system just for the purpose of communicating with my R/3 system. when i tried to assign this new logical system, i get a warning message saying "Be careful when changing your logical system". i have OK'd it and was trying to get into RSA1. I now get an error message saying "Your logical system has been changed and your request will be terminated" and will close the application. It also says that if i need to change my source system to my new one i will have to delete all my transfer structures, and shouldnt be using any ALE or workflow and ....etc. I cannot even get into AWB now but when i change my source system back to BWINST everything works fine.
    so can i use my first source system for communicating with my R/3 system...
    hope this is clear...
    thanks for trying to help me...

  • Problem when specifying LDAP connection

    This LDAP server is probably taken from local configuration, which works well with SQLPLUS.

  • ITSMobile - Problems when changing screen layout with CSS

    Good afternoon,
    I have a service ZLM00(SICF) with some public screens in the stile MOBILE4(Service of  internet-se80), and I am trying change your layouts with CSS.
    Steps taken:
        1 u2013 I activated the repository MIMES (/default_host/sap/public/bc/its/mimes);
        2 u2013 I copied the mobile.css from internet service standard ITSMOBILE for my service ZLM00(se80) with the name ZRF01.CSS;
        3 u2013 I added the parameter ~ITSMOBILECSSINCLUDE = ZRF01 in my service ZLM00(SICF);
        4 u2013 I published all screens and file ZRF1.CSS;
    The problem:
          When I test the service in the browser, I see in the source code that the file CSS was added u201C<link rel="stylesheet" href="/sap/public/bc/its/mimes/zlm00/99/ZRF01.css" type="text/css" />u201D
          And the screens received some changes, however when I added a new line in file CSS for exemple
    /* --- Basic Row -
          .MobileRow {
            white-space:pre;
            vertical-align:middle;
            background-color:#F3F3F3;  "new lineu201D
            Is not ok. Just the command standard works.
            I am doing something wrong ? Is missing some step ?
            My configurations:
             - Version SAP ECC 6.0/SAP_APPL 604 SP8;
             - Device mobile Symbol/motorola MC3190;
             - Operating system Windows CE 6.0 with Internet Explorer 6.0;
             SICF:
             ~THEME                          99
             ~TRANSACTION                          LM01
             ~ITSMOBILE                          1
             ~SOURCES                          ZLM00,ITSMOBILE
             ~POPUPS                           1
             ~ITSMOBILECSSINCLUDE     ZRF01
             ~ITSMOBILEELEMUNITS       px
             ~DYNPRO_COMPRESSION     1
             ~ITSMOBILECUAINCLUDE     ZCUAAREA
             ~ITSMOBILEELEMFACTOR      6
          PS: I am trying change the layout of the screens only to remove blank spaces placed on the screen MOBILE4, the objects do not fit the device screen.        
          Best regards,  
          Gerson S. Livio

    No.
    If you want to see how the screen will look; look in the iPhone/ iOS 7 section of this site.

  • CS5 Device Central Stage.width/Stage.height update problem when change the device profile.

    When creating FL 3.0/3.1 app   and testing it at the CS5 Device Central if you change the profile of the active device(select different phone with different screen size) Stage.width/Stage.height could't change. Always stays the same as the first device's Stage.width and height. Even if you add addListener with Delegate nothing happends. Also it effects to Screen Oriantation. It looks like a problem or is this a bug?

    Having the same problem, though I can't get it to connect even once. I just started researching the problem tonight - no solution yet...
    I'm on Windows 7 Pro 64-bit, Production Premium CS 5.5.
    I've got no other internet issues, Adobe update works fine.
    Please - Anybody have an idea how to troubleshoot this problem?
    Thank you.

  • SERVER.XML re-write problem when changing HTTP to HTTPS

    Hello,
    I am using SUN ONE App server and had a problem with turning SSL on in order to use HTTPS.
    What I did was that in GUI I selected a http listener under my instance and checked SSL/TLS Settings. I clicked Apply Changes button and I got a message saying that there wa a problem with XML-DOM. I checked my server.xml and found that its size was 0. It seems that it stopped re-writing it when it met the problem.
    An interesting thing is that when I created an additional http listener with SSL at a different port, there was no problem.
    It seems that the problem occurs only when I tried to change HTTP to HTTPS.
    Is there anyone who can tell me why this happens?
    I will appreciate any answers or comments.
    Thanks

    Hi,
    Is your Implementation Class is still the same (as the old one), when you changed the pre-fix.
    Just double click on the Implementation class and check whether the methods are still implemented or not.
    Thanks, Advay

  • Problem when change bank clearing account for payment posting.

    We recently changed the bank clearing account for payment posting (program PC00_M99_PPM). But I found out because the config can only be changed but not delimited on payroll side, the program errored out when it retro back for an employee to the old clearing account.  So what am I supposed to do to fix this problem?
    Have anyone ever handled this problem before and could please throw some light on it?
    Thanks in advance.

    check following
    1. Check in OMWD, whether Valuation grouping code "0001" ia ssigned to Ur plant
    2. OBYC - If you have assigned GR/IR Clearing A/c to WRX then check whether you have maintained it with combination of valuation class and GL A/c
    If yes then maintain only GL A/c w/o valuation class OR maintain one entry with valuation class empty and GL A/c

  • Jdeveloper 9.0.3.1 problems to change DB connection

    Inside the BC4JModule, at the configuration manager, it has the possibility to define the connection type. One JDBC URL and the other JDBC Datasource.
    At the first time I had defined my BC4J to use the JDBC URL connection an it worked. At the second deployment I chose the JDBC Datasource and had problems.
    To continue the development I decided to define my BC4J module again with the JDBC URL connection but with the JDeveloper 9.0.3.1 it is not more possible to change and "SAVE" the configuration again. It remains always to JDBC datasource connection.
    I started than the "OLD" 9.0.3 JDeveloper and it works. What is wrong?

    You should post this question to the Jdeveloper discussion forum for an appropriate answer: JDeveloper and ADF

  • Me22 Problem when change price for Conditions

    Hi,
    I have a strange problem about ME22. I explain the problem step by step:
    1) Enter ME22 with PO
    2) Select one PO Item (ex. the first item) and click on Services
    3) Select First Position.
    4) Click on Conditions and Change the Price.
    5) Back to Services, and repeat step 3 and 4 for second position
    When i change the price at first time work fine but, when i try to change prize the second time the dynpro Conditions appear empty and with row locked.
    This problem don't happen if i don't change the price in Condition Dynpro.
    In ME22N work fine. This is a problem because some batch-input on ME22 stop with error "input not possible" after step 5.
    There is a solution or OSS Note for this problem ?
    Regards,
    Angelo.

    Did you already had an answer on your problem? I am facing the same problem.

    You can use the HR Report RHINFT00 to make changes to the CS Descriptions.
    In the report Selection Parameters choose the CS Objects and enter the Infotype 1000. You will get a list of the CS Objects after the report is executed. Select the CS Object and choose the "Change" Icon to amend the description.
