  • How to get data from a file?

    Hello everyone, i'm new to this forum and to java too. Ok, so here is what i want to do:
    I want to get data from a file containing words and numbers and store them into variables that i will use them after to insert into a database table. For example i have a file called employees.txt in this form:
    eid ename zipcode Hire_date
    1000 "Jones" 67226 "12-DEC-95"
    In C++ i declare variables for each data and store them, for example in this case:
    ifstream in("somefile");
    string name, hdate;
    int eid, zip;
    in >> eid >> ename >> zip >> hdate;
    So i want to do the same thing in JAVA but i can't make it work. So, i would appreciate if someone could give me a simple example how to do it. Thank you.

  • How to read data from txt file respectively

    Hi,
    I am triying to form an equation between two known points. I want to do this with the attached VI, the most critical point is that I will read the x1, y1, x2 and y2 coordinates from the same .txt file. They will be written in a .txt file and I will send them to the appropriate channel (x1, y1, x2 and y2) respectively. How can I get data in a rule from a .txt file?

  • How to get text from column  labels in pivot using javascript?

    Hi, is it possible to get text from column labels in pivot using javascript? How?

    You don't get a response from a URLRequest, you get the response from a URLLoader:
    View this sample page for URLRequest and URLLoader and I think it'll make more sense to you.

  • Help: how  to get text from IFRAME

    <!-- The box where we type-->

    someone can tell me how i get text in my servlet from
    <IFRAME>
    thankx in advance...Hmm. I think you are mixing something up here. Why would you use an IFrame for entering text? IFrame is used for including content from different HTML-pages inside your page.
    If you want to have a textbox for an user to enter text into and submit it to a server, you need a form and a textarea inside that. Like this:
    <form action="myServlet" method="post">
    <textarea name="myArea">
    </textarea>
    <input type="Submit" value="Ok">
    </form>Change the action in the form to reflect the mapping to your servlet.
    Then you can just do a String enteredText = request.getParameter( "myArea" ); inside your servlet.
    If you insist that you need to use an IFrame, I guess the only way to do it would be to write a Javascript function, that copies the contents from the IFrame to a hidden field before the page is submitted to your servlet. In your servlet you would read the value from the hidden field.

  • How to get data from COSP table, field HRKFT as the key to data from PM?

    Dear ladies and gentlemen!
    I need to get data from COSP table, field HRKFT as the key to data from PM tables (AFKO and AUFK).
    The problem is that it is a key field to the COSP, and all non-key fields as an alternative to HRKFT are not suitable for this task.
    All this is necessary for the extractor, which loads the data from the R \ 3 systems in the BW-system. I need to perform SELECT from a table COSP and maybe also JOIN, most likely between tables COSP and AUFK.
    What should I do in this case?
    Thank you very much in advance!

    From information on help.sap.com I've made a conclusion that one of possible solutions in theory is to modify standard extractor PM_OM_OPA_1 in order to make HRKFT field available for work, because by default it is hidden by SAP and not available for use as a key field.
    Of course, it's not a very good solution, but for now I know no other way to solve this problem.
    Maybe someone knows better ways? In this case I will be very grateful for any help!

    please suggest me, how to retrive EUC-KR text from the XML file

    Standard Java does not support this Charset. You have to find a charset provider that implements "EUC-KR". But you should also consider using Unicode, which is implemented in standard Java.

  • How to get resources from jar-files

    Hi
    in my app I load an image via the Toolkit.getImage() method.
    Works fine if the app and the image are in folders on disk.
    It fails to load the image, if the app (and the image) is packed in a jar file.
    How can I get the image from there?
    I try to get the image as follows:
    String s = getClass().getResource("MyApp.class").getFile();
    AppPath = s.substring(0,s.lastIndexOf("/"));
    String PathToImages = "/images";
    MyImage = (Image)Toolkit.getDefaultToolkit().getImage(AppPath+PathToImages+"/logo32.gif");The App starts and works, it just fails to load the images.
    Any solutions??
    thanx in advance
    Herby

    This is actually pretty easy. First a little background.
    A Jar file is just a Zip file, with a few constructs for Java.
    The getResource() method is used to create a mapping to data within the Jar file, but is actually not necessary after you know how the mapping works.
    Just to give you an example of getResource:
    // returned is a url to the resource you want from your Jar file.
    URL myURL = MyClass.class.getResource("images/myimgage.gif");
    // then you can use this URL to load the resource
    Image img = getImage(myURL);If you were you look at the value of myURL you would see something similar to the followiing.
    jar:http://www.mywebsite.com/mydir/myjarfile.jar!/images/myimage.gifJust to break it down for you.
    The line always starts with the word jar:
    Followed by the path to your jar file.
    A sepearator !/
    Then the file you are loading from the Jar file.
    jar:     path_to_jar_file     !/     path_to_resource_in_jar_fileSo if you'd like, you could just create a URL object, and define the path to the object using the above method rather than using getResource.
    Anyway, back to your code. What I would do is print out what you get for:AppPath+PathToImages+"/logo32.gif"I'm thinking you might be getting 2 "/" in your path because I think:AppPath = s.substring(0,s.lastIndexOf("/"));will leave the "/" at the end and the next line you add the "/" in front of the image directory name. So you my have the following for your image path.mypath//images
