Reading one file at a time using File Adapter

I am using a File Adapter which polls every minute to read files from a Folder. This process picks up all the files in that folder. What I want to achieve is that the File Adapter should read one file at a time. Is it possible to force it to wait for a few seconds before reading the Next file in the Folder. Or is there a solution to what I am trying to achieve? Any help would be appreciated.

public static char readChar() {
int ch;
char r = '\0';
boolean done = false;
while (!done) {
try {
ch = System.in.read();
r = (char) ch;
if (r == '\r') {
System.out.println("Not a character. Please try again!");
System.in.skip(1);
done = false;
} else {
System.in.skip(2);
done = true;
} catch (java.io.IOException e) {
done = true;
return r;
Try this as an method and then use it..
This code will read will be in response untill you hit the return key but will take only the first character....

  • Read one word at a time from a text file

    I want to read one word at a time from a text file as it is done by "scanf &s" function in text based programme. It is not possible by " read from text"  function. Suggest me  function or method to solve this.

    The simplest way is to use the spreadsheet string to array function with the space character as the delimiter.
    Note that this won't work unless there is a space character between the words - it won't work with line feeds / carriage returns between the words but you could always split the string into lines first. You may also want to trim whitespace to remove any other non-visible characters (e.g. tab, line feeds) from around the word.
    If you need something more sophisticated that splits based on whitespace (e.g. tab, new line) then you'll probably need to do something with searching the string for these characters (e.g. using a regular expression) and then splitting them yourself into an array.
    Of course...if you actually want to just read one word at a time from the file rather than just split the file into words (I assumed you meant this), you will need to read the file byte by byte using the low level file IO functions, build a buffer of the bytes and check the character you've read to see if it a space.

  • Read one record at a time

    Hi !
    One of our Java folks here need at function where he reads one record at at time in id order;
    create table url_recs (id number, url varchar2(4000));
    insert into url_recs values(1,'www.fona.dk');
    insert into url_recs values(2,'www.dr.dk');
    insert into url-recs values(17,'www.ihk.dk');
    select read_rec() from dual; - get id 1
    select read_rec() from dual; - get id 2
    select read_rec() from dual; - get id 17
    select read_rec() from dual; - get id 1 - "no more rows - start all over again)
    select read_rec(45) from dual; - get NULL (no rows with that id)
    select read_rec(1) from dual; - get id 1
    The purpose id for some "round robin" trying to get to some internal URL's.
    Can you give me a hint for creating the function(s)
    best regards
    Mette

    Will successive calls come on the same Oracle session? Or across different Oracle sessions?
    If you're going to call the function multiple times within the same Oracle session, you could store the last value returned in a package variable and select the record whose ID is greater than that value every time the function is called. That's unlikely to do exactly what the Java developer is hoping, though, because the Java calls are likely to bounce between multiple Oracle sessions due to connection pooling. And it'll likely require that the Java developer (or app server admin) adds some code when they get a connection from the pool where they reset the package state. Or it'll require that someone develop a method to keep the Java and Oracle session state in sync.

  • Apps to mix sound files in real time, using two soundcards?

    Can someone recommend some applications for linux to mix audio files (mp3, ogg) between two soundcards?
    in realtime... you know, like DJs do, etc...
    TIA, and sorry for the bad english
    luciano

    I think if you use more than one card at a time you're going to run into latency issues, since there is no guarantee that the output from two or more cards will be synchronized. If you really need more than two channels out, a better solution is to purchase a professional card with as many outputs as you need. Also, I don't think Jack (the standard for audio work in Linux) supports the use of more than one card at a time.
    I can't think of a reason you would need more than two channels (one left, one right) unless you're trying to DJ in surround sound. Don't DJs using traditional gear just run a pair of turntables through a crossfader?
    I haven't used the program, but Mixxx looks like the best Linux software for DJing. You might take a look at it first.

  • Appending in file and supplying file name at run time using File Adapter

    Hi,
    Can we use File Adapter to write in a file in append mode. i.e. a BPEL process opening a file appending some text and closing the file each time it called.
    Another query is can we create the file at run time with the supplied file name?

    In order to append to a file, we can use Append="true" in the interaction spec for the File/Ftp adapter.
    <jca:operation

  • Posting a File with Date Time using FTP in a BPM scenario

    Hi All,
      I have got a following requirement within the BPM ::-
    Step 1: We receive a file from an external system using FTPS with File Content Conversion Mode. The file is a comma separated file.
    Step 2 : We need to write the same file without any changes in data elements to another File System. The file to be written will be comma separated.
    Step 3 : The data will be mapped to an RFC and there will be a RFC Call to the ECC system.
    Step 4 : On successful call to RFC, the file will be dumped into the SAP File system also.
    The issue here is in Step 2. The additional requirement for Step 2 is to name the file with the following convention -
    ABCDEF_<Date in MMDDYYYY>_<Time in HHMMSS>_<Time in ms>_data.txt
    Can you help me on how to configure this from within the BPM ? I have seen blogs and replies in forum on using UDF's for the same. I am not sure on how to do this in BPM.
    Please help !!!
    Thanks,
    Amit

    Hi,
    I dont think you required BPM in this case,you can achieve this requirement using Multi mapping.
    3 Receive comunication channels
    1)to send file to receive File directory9Content conversion required)
    2)RFC Receiver Communication channel to make a cal to SAP ECC to send RFC..
    3)One more File communication channel to send data to SAP File System.
    refer below blog.
    /people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible
    Regarding r file name use dynam ic configuration UDF or ASMA to chnage file name format to your desired format,if you decided to use UDF then map root nod of receiver file structure in multimapping.

  • Why cant poll a file more than once using File Adapter..

    Hi All,
    When we run webservice, as I am using File Adapter to read/write the file information.
    Usually, File Adapter reads once every file and it wont read again the same file whcih already red.
    Where and How this status maintained by File Adapter/BPEL in the system.
    Where this will be avvailable and why cant File Adapter read/poll the same file.
    Pls can any one of you share your ideas on the same.
    Thanks.

    Hi,
    Tried to get some information around where ftp adapter stores the timestamp but couldnt find anything useful.
    But we have a table for File adapter which captures the processing information (FILEADAPTER_IN )
    I dont have the setup for FTP adapter to run an example. If you could try the below we can clarify that the timestamp is not stored in memory.
    Configure as usual for a folder with a file pattern for FTP adapter.
    Drop a file to process it and then restart the SOA Suite and try to drop the same file with same timestamp to see wheather FTP adapter picks up or not.
    Ideally i feel once you restart the SOA Suite it should pick up the file, if still not picks up the file for second time then we need to dig indepth to see where this information is stored.
    btw what is your usecase ?
    Thanks,
    Vijay

  • How to get file from FTP Server using File Control

    Hi,
    Any one did getting file from FTP Server?
    Please let me know any one help me.
    I would need to get file from FTP Server.
    Thanks,
    Madhu

    Yes I have done that. But In FTP Server I cannt read file, because no previliges. Only I need to copy file from FTP Server to local server then only I can read that file.
    I tried all options using FileConrol(getFiles(),read()).
    getFiles() - It wont copy the file, it give information about file.
    read() - I dont have previliges to read the file.
    Please tell me any other procedure would be there for getting file from FTPServer.
    Thanks,

  • File type/quick time movie file

    My iTunes library used to have a preponderance of mp3 files. Now these seem to have been converted to Quick Time movie files. This might have occurred during an update. What happened and what does it mean.
    Many thanks,
    Wells

    Wells,
    Unfortunately the page you mention (http://www.cminow.org/itunesapplescriptfixer.html) will not load.
    Give it a couple more hours or try:
    http://www.cminow.com/itunesapplescriptfixer.html
    That's my site, and I switched the IP address about four hours ago, and the DNS is probably still pointing to the wrong address. For some reason, the ".com" address changed over really fast (at Comcast anyway), but the ".org" one didn't.
    Here's the AppleScript:on open badfiles
    repeat with i in badfiles
    set the item_info to info for i
    --Change "mp3" to "mp2" in the following line for MP2 files:
    if (name extension of item_info is "mp3") and (folder of item_info is false) then
    tell application "Finder"
    --Change "MPG3" to "MPG2" in the following line for MP2 files:
    set file type of i to "MPG3"
    set creator type of i to "hook"
    end tell
    end if
    end repeat
    end open
    Just copy and paste that into the Script Editor in your AppleScript folder in Applications. Save it as an application. Then find one of the files that's giving you problems and drag it onto the application. It should change the type and creator and iTunes should be happy.
    In order to avoid this in the future, just download the MP3s directly onto your hard drive by control-clicking or right-clicking on the link to the MP3. Choose the menu item that downloads to disk. In Safair, it's "Download Linked File". That avoids the QuickTime Browser plugin, which is what gives it a type of "MPEG" and creator of "TVOD" instead of "MPG3" and creator of "hook", which is what iTunes is happiest with.
    Let me know if any of this wasn't clear, and I'll try to explain it better...

  • How to add header line in a file from XI system using file adapters

    Hi All,
    I need to add header line (Column names) in a file coming from XI system.
    I am using file adapters.
    Thanks & Regards,
    Gaurav Mittal

    The Receiver File Adapter is configured, using the following settings:
    1) Choose File Content Conversion as the Message Protocol.
    2) You give the ‘addHeaderLine’ parameter as 1
    3) For the ‘fieldSeparator’ parameter you need to give field separator for both list and substructure (referring to the data type above). For eg: it may be a ‘,’ (comma) for substructure in a comma separated file.
    4) The ‘endSeparator’ parameter needs to given for substructure only. For eg: it may be a ‘nl’ (new line)
    5) Give the file name, the directory and the Construction mode. Activate all the settings. Receiver File Adapter with F.C.C. is configured.

    Hi Friend,
    I reading the serial port  one character at a time ,  i specified it in the "serial bytes to read" option in serial port read examples.
    The problem is ----------i can able to read  the data.
    but only the first character is reading again and again...and "reading string indicator" in the serial port example shows only the first character sent ..only for a single time.since i am reading continously ----aleast the first character should display as many times i running the program
    (i am running the vi by run continous option..........)..
    please help me ....how to read the character one by one.....
    regards
    rajasekar

    Hi jason...
    I can able to read the serial port by 1 byte or 2 byte or 4 byte as i can specify it in the serial port read bytes option..(in visa serial read)..
    I need to acquire 4 bytes of data and pass it to the Math-script node..and save these 4bytes of data in array (1 row and 4 column)..
    And split this array(just like array-indexing.vi) and processing it each each column separately....
    or suggest some method to achieve my task.....please.
    one more thing the math-script node is placed in a while loop.....in order to read sequence of bytes continously.......
