  • How to read a string from file & assign the val to a variable in batch file

    Hi,
    How to read a string from a file and assign the value to a variable then return the value to the screen in windows batch file?
    Any suggestions?
    thanks.

    Unless this is a homework question then I don't see the purpose of doing this, but....
    You should be looking a the supplied package utl_file to get the string out of the file, dbms_output to display the string and then google windows batch/command files calling sqlplus to execute your program.

  • How to read the current selection in a table.

    Hello Experts,
    I've this issue with the web dynpro. I have a Adaptive Webservice Model in web dynpro. And I have three tables in the UI. When a row is selected in the first table, the second table is populated with the appropriate data (using a method in the web service.) the same applies to the third table, when the a row is selected in the second table, the third table has to be populated with the appropriate data. The methods in the web service are all working fine. However, in web dynpro, I am not able to figure out on how I read the selected row in a table. Any information on how to resolve this would be really really helpful.
    <
    wdContext.currentGetMailElement().setProfileID("-Should be read from the selected row in the table.");
    wdThis.wdGetMailControllerController().executeGetMail();
    >
    regards,
    Sam.

    Hi Samuel,
    I didnt clearly understood  your problem. When you are selecting a particular row in a table you are executing a web service named Get Mail. Are you passing any input parameter(any selected row data)  while executing a web service. And when you get the response node where you have a attribute in the node getmail. Am I right.
    If this is the case, then first check if the GetMail node is present or not by comparing it will null or checking its size. If the node is null then you will not get attribute as the element itself is null as nothing is retrieved in response. And if the node is not null then the element at 0th position is selected by default. you can retreieve the attribute by directly using the following code
    if(wdContext.nodeGetMail() !=null)
        String profileId= wdContext.currentGetMailElement().getProfileID();
    Check if this works for you.

    Hi, 
    I would recommend you to have a look at the VI attached. It makes use of a VI named 'Read from Spreadsheet' to read the row and column data from the tab delimited excel file. The read data is then searched for the Alphabet specified and finally returns you the corresponding string. The test file used to validate the operation of the VI is also attached. 
    Trust this would help you solve the issue.

  • Help me...How to read the content if "Transfer-Encoding:chunked" is used?

    I am doing a project for internet control using Java,PHP and MySql.All sites should go through the proxy server only.If the HTTP header contains Content-Length,am getting the content length as below:
    public class HTTPResponseReader extends HTTPMessageReader
        String statusCode;
        public HTTPResponseReader(InputStream istream) throws IOException,                     NoSuchElementException
      BufferedInputStream distream = new BufferedInputStream(istream);
      retrieveHeader(distream);
      StringTokenizer st =  new StringTokenizer(new String(HTTPMessageReader.toArray(header)));
      versionProtocol = st.nextToken();
      statusCode = st.nextToken();
      String s;
      while (st.hasMoreTokens())
            s = st.nextToken();
            if (s.equals("Transfer-Encoding:"))
           transferEncoding = new String(st.nextToken());
         if (s.equals("Content-Length:"))
           contentLength = Integer.parseInt(st.nextToken());
         if (s.equals("Connection:"))
          connection = new String(st.nextToken());
          if (connection.equals("keep-alive")) mustCloseConnection = false;
       retrieveBody(distream);     
    }After getting the Content-Length,i used read method to read the content upto that content length.Then i concatenated the HTTP header and body and the requested site was opened.But some sites dont have Content-Length.Instead of that,Transfer-Encoding is used.I got the HTTP Response header as "Transfer-Encoding:chunked" for some sites.If this encoding is used how to get the length of the message body and how to read the content.
    Can anybody help me.
    Thanks in advance...

    Why don't you use HttpUrlConnection class to retrieve data from HTTP server? This class already supports chunked encoding...
    If you want to do anything by yourself then you need to read HTTP RFC and find all required information. Well in two words you may reject advanced encoding by specifying HTTP 1.0 in your request or download chunked answer manually. Read RFC anyway :)

  • How to read the DB application error in JSP

    We have the PL/SQL triggers that perform validations on the insert and update. If validation fails the RAISE APPLICATION ERROR is used.
    On error the errorpage.jsp is called correctly, but my problem is that I can not read the actual error message from database.
    All I am getting from exception.getMessage() is the JBO message. The exception.printStackTrace() does not help either. How can I read text of PL/SQL exception message ?
    I have tried this test in errorpage:
    if( exception instanceof oracle.jbo.JboException ) { ...}
    but apparently the exception is not JboException, since test fails.
    I read about ApplicationModule.setExceptionHandler() and even build exception handler which does not do anything. I assumed that this would allow all exceptions to be passed to the error page. Nothing like that happens though. I still see only last JBO exception, I can not see the original DB exception.
    Thanks in advance,
    Michael

    Hi ankur,
    thanks for the quick reply,
    I have got the answer for the first question.
    Can u tell me solution for the 2nd question also. how to read the Portal user information in VC. like reading the Portal user information in webdynpro.
    In webdynpro we can read any of the portal user properties or information like using the following code.
    Itry{
    IWDClientUser user = WDClientUser.getCurrentUser();
    String fName = user.getFirstName();
    String lName = user.getLastName();
    }catch(Exception e){
    In the same way to read the portal user information in VC. BCz for every portal user we have created one custom properties, we need to read that propety value in my vc application, when the user logged in to portal and accessing integrated VC application.
    I have seen one of the thead this is possible from VC7.0 of NW2004s, current my version is also the same.
    Portal 7.0
    VC 7.0
    If u know how to do that, can u let me know.
    Regards

  • How to read the API

    I am trying to understand how to read the Java API. I have bought Oracle's Books "Java The Complete Reference" and "Java A Beginners Guide" but am still unsure how to read the API.
    Let me clarify what I'm asking to avoid confusion.
    The class java.util.ProcessBuilder http://download.oracle.com/javase/7/docs/api/
    Has a Constructor section that lists
    Constructor and Description
    ProcessBuilder(List<String> command)
    Constructs a process builder with the specified operating system program and arguments.
    ProcessBuilder(String... command)
    Constructs a process builder with the specified operating system program and arguments.
    How do I read the ProcessBuilder(List<String> command) so that I can understand it and implement its use?
    Later when it talks about methods such as List<String>      command()
    Returns this process builder's operating system program and arguments.
    How do I understand this and make use of the method?
    Is it possible for this to be explained to cover the whole API so that when a class is looked up the constructor and methods are explained that someone who does not understand can take any class and have the constructor and methods from the API and know how to implement them?
    Thank you

    As with a lot of questions like this, Google is your friend. A Google of "using ProcessBuilder" gave me a pile of useful pages on how to use the class (which the API docs aren't always wonderful at doing), including some common 'gotchas' - although many of these are related to <tt>Runtime.exec()</tt>, which Process/ProcessBuilder was created to improve.
    One of those pages was for [url http://commons.apache.org/exec/index.html]Apache Commons Exec, which you might also want to look at (although it does require a download, and that might violate the rules of your exercise too). I've never used it myself though, so I can't comment on how good it is.
    Alternatively, it might be worth talking to your instructor and explaining your problem. Most of us are reasonable chaps, and s/he might be able to provide you with some good tips.
    Remember: plagiarism is the programmer's stock-in-trade. There's nothing wrong with using something written by someone else as long as you attribute it - that is, after all, what classes are all about :-).

    hi,
    I am reading a AFP file in hexstring format.But it is out put is not perfect means it is showing output close to the real one.
    How to read the file so taht i can get exact output in hex format.
    try{

    AFP is a IBM format for printing. Somehow i will be able to read that but how to covert it back to that format and store to that file.
    by trying is just storing data in hex format only
    Writer outhex = new OutputStreamWriter(outputStreamhex,"Cp1252");
    is there anyother way to store it back to this format
