  • What are the cases that cause the I/O error writing to output file

    may i ask what are the cases that cause the I/O error writing to output file ??
    cause i have the write path and the input file has data
    any ideas???

    and the permission is to write first time then append to itBy "permission" is meant the operating system controlled rights that let
    particular users do specified things with specified files or directories.
    the error message is a the title of the message
    I/O error writing to output fileThe java runtime actually creates a much more useful error message than
    this but, unfortunately, your program is swallowing this error message and
    replacing it with the message you see.
    Somewhere in your code you have something like:try {
        // all sorts of stuff goes here
        // including the code that is intended to
        // write to the file
    } catch(IOException ioe) {
        System.out.println("I/O error writing to output file");
            // add this line
        //ioe.printStackTrace();
    }It might say Exception rather than IOException.
    To get a much more useful error message add the commented line.

  • How to avoid output file and error lines when condition does not match

    Hi Experts
    A customer want to send purchase order files to several vendors and each vendor has their own requirement to content and file format. I have prepared scenarios for each vendor and a template is (conditionally) called when CardCode matches. It works fine, - PO file is generated when CardCode matches, but error lines are written to SAP B1 Control Center each time CardCode does not match the one defined in a scenario (100 or more times per day). Problem is that these error lines does not get automatic deleted. Conditional processing are made in this way:
    Result Message in SAP B1 Control Center when CardCode does not match:
    I tried to avoid an error line in SAP B1 Control Center when CardCode does not match in this way:
    Then no error lines are written to SAP B1 Control Center, but an output file is generated each time (order file when CardCode matches and an empty file when CardCode does not match).
    Any suggestions on how to avoid both errors types (error lines in SAP B1 Control Center and empty output files)?
    Or - can lines in SAP B1 Control Center be automatic deleted?

    Hi Steen,
    using <b1im_skip> should be the right approach, if you're working with B1 OUTBOUND.
    Following extract form the B1i help describes the usage to skip the outbound processing:
    1.1 Skipping Outbound Processing
    If you do not want to hand over the message to the receiver system, the scenario step can create a special tag that indicates to generic processing in the integration framework to skip the message processing.
    Add the following to the final transformation atom (atom0):
    <b1im_skip xmlns= ”” info=”my info” msglog=”true” msgout="yes">
    If the integration framework skips the message, it puts the message log information to the Filtered section, if the message log is switched on. The result message contains the Message skipped by vBIU logic information.
    info
    To display an individual message, define it using the info attribute.
    msglog
    If you want to avoid an entry in the message log, introduce the msglog attribute and set it to false.
    msgout
    To display the skip information in the Success section of the message log, use the msgout attribute and set it to yes.
    In case you don't want any MsgLogEntry in case of a skipped message, please enter the following in final atom0:
    <xsl:template name="transform">
    <xsl:attribute name="pltype">xml</xsl:attribute>
    <xsl:choose>
    <xsl:when test="$msg/BOM/BO/Documents/row/CardCode=&apos;C20000&apos;">
    <xsl:call-template name="transform2"/>
    </xsl:when>
    <xsl:otherwise>
    <b1im_skip info="skipped" msglog="false"/>

    </xsl:template>

  • PDF file lines aren't vectors but rectangles.

    I have a PDF file which has been produced in Indesign (it may originally have been created in Illustrator or Photoshop).
    On opening the PDF most of the vector parts of the file are not true lines but seem to be rectangles or the outer edges of a line in this particular case 0.105mm's apart.
    I have noticed this before with PDF's and it is very frustrating.
    I am trying to create a dieline from these files and if I tried to create a cutting die from this, the laser would create an unholy mess when it tried to burn.
    Is there some kind of setting that makes sure the PDF is created with true vector lines?
    If anyone could shed some light on this I would be most grateful.
    Many Thanks in  advance,
    Dahzee

    Bob & Grant, thanks for taking the time to reply.
    Could you please just give me one more piece of information.
    I am so far down the food chain from whoever is doing the Artwork, I get very little say in how this is created.
    Is there one instruction I can pass back up the line to the Designers that could give me at least a fighting chance of having a decent single line file to make my dielines?
    I am a CAD guy so I have no concept of what the Designers are doing in Illustrtator, Indesign or Photoshop.
    Thanks again in advance.

  • Writing to an output file

    Hello all,
        I have an ABAP program in BW which reads the data from a BW ODS active table and writes the output to an external file on the server.
        The file that is generated is huge(13 MB). The file is generated with the correct results, but along with the data, the program header(filename, path, etc) is also written to the output file which is undesirable. The header is written for every few hundred pages. I want to avoid this.
    Database is Oracle.
       The syntax for the file declaration is..
    PARAMETERS: fileout(120) type c lower case default 'xxxx.csv' 
                        obligatory.
    and the open statement is as follows....
    OPEN DATASET fileout FOR OUTPUT IN TEXT MODE ENCODING DEFUALT.
    In the above statement I want to try taking out the "ENCODING DEFAULT" clause, but it says "in TEXT MODE the ENCODING must be added". I have seen other programs which are already there without that clause.
       Any suggestions will greatly appreciated. Thanks.

  • Using `n how can i add two empty line (two carriage return), between these two lines in the output file?

    hi friends
    using `n   how can i add two empty line (two carriage return), between these two lines in the output file?
    PS C:\> $env:COMPUTERNAME | add-content c:\file.txt
    PS C:\> $Env:USERDOMAIN  | add-content c:\file.txt
     i tested "$env:computername`n`n`n$env:userdomain" | add-content c:\file.txt   but it results in 
    myPCMyDomain
    but i wanted the contents of the output file be like this:
    MyPC
    #empty line here 
    #empty line here
    MyDomain
     i tested many other forms but didn't work.
    thanks

    I tried it, as well. The line breaks were respected in the PowerShell console, Programmer's Notepad, and Word; they weren't in Notepad.
    You are using a Unicode file.  Locale is what?
    If you just want notepad compatible line breaks then do this:
    del file.txt ; "$env:computername`r`n`r`n`r`n$env:userdomain" | add-content file.txt ;notepad file.txt
    Look in hex to see that `n is ^L or 0xA and is only one character.  CrLf is 0xD 0xA - two characters.
    My programmers editors and VS all understand a single ^L as a line break so does PowerShell.  Only DOS/Notepad and other utilitis don't understand this..
    ¯\_(ツ)_/¯

  • Applet writing on a output file

    I am new to JAVA and I've got jdk 1.4.1 downloaded.
    I am thinking it is possible to have a JAVA applet
    which writes on a output file.
    In order to do that, I tried to use the code below, where the Applet "write.class" should display a string on a painted area and write to file "myfile.txt".
    Now compilation is OK (no error or warning messages), and I tried to incorporate this Applet into a HTML code (by using the sintax <applet code="write.class" width=200 height=50> </applet>).
    When I open the HTML document using Internet Explorer the Applet is run, but the file "myfile.txt" is not created.
    Can somebody explain me what is going wrong?
    Any suggestion or comment is welcome and appreciated.
    import java.applet.Applet;
    import java.awt.*;
    import java.io.*;

    applets are not allowed to write to the local file system.

    Try 
    http://stackoverflow.com/questions/10340007/exporting-powershell-output-to-text-file
    You can always redirect the output an exe to a file like so (even from cmd.exe):
    powershell c:\test.ps1 > c:\test.log
    Within PowerShell, you can also redirect individual commands to file
    but in those cases you probably want to append to the log file rather
    than overwrite it e.g.:
    $logFile = 'c:\temp\test.log'
    "Executing script $($MyInvocation.MyCommand.Path)" > $logFile
    foreach ($proc in Get-Process) {
    $proc.Name >> $logFile
    "Another log message here" >> $logFile

    Sorry about the long lines.
    As you can see, all input files saved in array called files, however when OpenFile1() function is called, it take input (fileName_in) as a single file not an array. I'm assuming this causes the exception.
    When there's muptiple inputs, program should take each file from getFileName() to outputToFile() sequentially.
    Does anybody have an idea to solve this?
    Thanks a lot!!

    you naming convention is confussing. you should follows Java naming convention..you have a getXXX but decalred the return type as "void"...get usully means to return something...
    your code is doing too much..and hard to follows..
    1. get the selected files
    for each selected file
    process the file and return the result
    write out the result.
    /** close the precious resource */
    public void closeResource(Reader in){
        if (in != null){
            try{ in.close(); }
            catch (Exception e){}
    /** get the total number of line in a file */
    public int getLineCount(File file) throws IOException{
        BufferedReader in = null;
        int lineCount = 0;
        try{
            in = new BufferedReader(new FileReader(file));
            while ((in.readLine() != null)
                lineCount++;
            return lineCount;
        finally{ closeResource (in);  }

            String line = null;
            while ((in.readLine() != null){
                .. do something with the line
                result.append(....);
            writeToFile(outFile, result.toString());
        finally{ closeResource (in);  }
    public void writeToFile(File outFile, String result) throws IOException{

  • Read file line by line

    Hi
    Could somebody tell me how to read file line by line ? Namely my input file I want to read look as follow:
    AAA 1, 1
    12 222 12
    AAA 2, 2
    11 122 11
    My output file should look as follow:
    1, 1, 12
    1, 1 222
    1, 1, 12
    2, 2, 11
    2, 2, 122
    2, 2, 11
    I think the lines need to be stored in ArrayList, then I would like those lines to write to csv file, but how on read I can construct such output file? This is my code for reading file
    public ArrayList readFile(String filename)
      try
         BufferedReader in = new BufferedReader(new FileReader(filename));
         ArrayList list = new ArrayList();
         String lineS = null;
         while (in.ready())
          if ((lineS = in.readLine()).startsWith("")){
            String[] line = in.readLine().trim().split("\\s+");
            list.add(Integer.valueOf(line[0]));
            list.add(Integer.valueOf(line[1]));
            list.add(Integer.valueOf(line[2]));
         in.close();
         return list;
         catch (Exception e)
       e.printStackTrace();
    return null;
    Thanks

    The rules for the conversion from input to the desired output are:
    1. For each of the line with string take 2 integers for example 1, 1  from AAA 1, 1
    2. Then repeat 1, 1 for each next number not containing any string, so if the line after AAA, 1, 1 has 12, 222, 12 then the output will look as follow
    1, 1, 12
    1, 1 222
    1, 1, 12
    3. Repeat the process (the pattern is the same 1 line with string 1 line with numbers)
    Actually I am not sure how to perform that logic for such conversion as for now I am only able to list only the numbers but I have a problem to add numbers from the line having string in it.
    STOP!
    You should NOT be writing code if you are 'not sure how to perform that logic'.
    You are getting ahead of yourself.
    There is NOTHING to gain by trying to code a solution before you know what algorothm you need. Big mistake.
    Should I use list or maybe if the patter for lines is the same array will be more sufficient?
    NEITHER ONE!
    Those are 'solutions' used to implelment an algorothm.
    You do NOT yet know what algorithm you need to use so how can you possibly write code to implement the unknown?
    How to perform logic to get the numbers from line having string and for the next lines having only numbers in order to structure it into desired output? 
    THAT is the question your thread subject should have.
    Until you get the answer to it don't write any code,.
    Do NOT try to automate what you can't do manually.
    Write down, on paper or use an editor, the step by step 'logic' you need and walk through that logic from beginning to end until the 'logic' works and produces the correct result.
    You just now have started to do that when you listed those rules above.
    But you left some things out. Expand on that list of 'rules' and provide a little more example data. TPD has given you a good example. Reread what they said.
    Did you notice they start by talking about 'tasks': what each task does and the order the tasks need to be performed.
    That 'task list' has NOTHING to do with Java, C, or any other language: it is identifying the problem/algorithm. Until you have that coding is premature.

  • Help!! writeUTF is writing some junk chars to my file

    hi guys,
    I am breaking my head with this. please help me out
    I wrote a servlet which reads the input sent by an applet
    the applet sends a hashmap object called manifest to the servlet
    i am reading the contents of this manifest object into a file using writeUTF
    but when i open the file to check the contents
    every line has some erroneous characters at the beggining of the line
    i am not understanding why these junk characters are writted, when i am making sure that i am writing correctly
    i am appending the code also to this, please verify:
    File lmin = new File(userFile.getPath()+"/"+"Lmin.txt");
    FileOutputStream tolmin = new FileOutputStream(lmin);
    DataOutputStream dos = new DataOutputStream(tolmin);
    out.writeUTF("s&f"+(String)manifest.get("s&f")); //manifest is Hashmap object
    dos.writeUTF(manifest.get("-s").toString().trim()+"\n");
    when i am printing manifest.get("-s").toString().trim() to the outputstream it doesn't show any additional characters, but the file Lmin.txt has these junk characters.
    why is this so??
    thanks
    pre_pra

    I've simplified your code.
    import java.io.*;
    public class Test {
        public static void main(String[] args) throws Exception {
             DataOutputStream dos = new DataOutputStream (new FileOutputStream (new File ("test.bin")));
             dos.writeUTF ("123456");
             dos.close();
    }The output is written to a file named test.bin. I've printed the hex dump of the file.
    C>hd test.bin
    0000    00 06 61 62 63 64 65 66                            ..abcdefYou can see from the dump that writeUTF writes the length of the string (00 06) and then the bytes, encoded in UTF-8 (just ASCII in my case). The junk that you can see in your file is the length of the string that writeUTF wrote to the output file.
