How to write and read array on ObjectOutputStream............??

Hello All...........,
I have done some code for applet and servlet communication in which i writes "String " as an object and gets reply from servlet as a string as follows:
           // send data to the servlet
                        String input="hello there.....";
               URLConnection con = getServletConnection();
               OutputStream outstream = con.getOutputStream();
               ObjectOutputStream oos = new ObjectOutputStream(outstream);
               oos.writeObject(input);
               oos.flush();
               oos.close();
               // receive result from servlet
               InputStream instr = con.getInputStream();
               ObjectInputStream inputFromServlet = new ObjectInputStream(instr);
               String result =(String) inputFromServlet.readObject();
                         outputField.setText(result);
                       //outputField.setText("good morning");
               inputFromServlet.close();
               instr.close();This code is same at servlet end.
But now i want to pass an int array.How to pass int[] as an object.
It is giving me error if i pass int array as int array[]={1,2,3}; oos.writeObject(array); Why is it so?
Can anybody tell me how to write and read int array[].
Thanks.
Shraddha.

hello kaj,
I am trying to write as follows
while writting:
int array[]={1,2,3,4,5};
URLConnection con = getServletConnection();
OutputStream outstream = con.getOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(outstream);
oos.writeObject(array);
oos.flush();
oos.close();
while reading:
InputStream instr = con.getInputStream();
ObjectInputStream inputFromServlet = new ObjectInputStream(instr);
int result[] =(int []) inputFromServlet.readObject();
Thanks,
Really imp for me.

    Thanks for answering
    RodgerWith Java you cannot write to a specific memory location. Java does not have pointers. If you really want to do it, you need to use JNI, i.e write the required functions in C (or other languages that support pointers) and make those functions available to Java (through JNI). This approach is not portable. You can have a look at http://java.sun.com/docs/books/tutorial/native1.1/index.html

  • How to write and read Japanese on my Nokia E5

    I am trying to find out how I can write and read Japanese on my Nokia E5.
    I even don't knwo if it's possible...
    Does anyone have the answer???

    Hello ikokitakun,
    I believe you have to load a version of software on your phone that has the Japanese language pack in it because the version of software on the phone only has the languages for the region that you bought the phone in. for example if i bought my phone in NZ it would have English, Malaysian and maybe Philippino. There are "dodgey" places you can go to get the software changed but if you do this you void your warranty so be careful. Nokia doesn't condone the changing of regional software.
    Hope this helps

  • HOW TO WRITE AND READ FROM A TEXT FILE???

    How can I read from a text file and then display the contents in a JTextArea??????
    Also how can I write the contents of a JTextArea to a text file.
    Extra Question::::::: Is it possible to write records to a text file. If you have not idea what I am talking about then ignore it.
    Manny thanks,
    your help is much appreciated though you don't know it!

    Do 3 things.
    -- Look through the API at the java.io package.
    -- Search previous posts for "read write from text file"
    -- Search java.sun.com for information on the java.io package.
    That should clear just about everything up. If you have more specific problems, feel free to come back and post them.

  • How can i write and read the same data

    hi,
             i have attached my program to this mail. i have some problems in this program.
    problems:
    1. I want to select the threshold for the rms,varience and s.d.
    But what i used is not doing that. i want to fix the upper threshold value and lower threshold value.
     when ever the input crosses upper threshold value i want the output and it will remains uptill the value above the lower threshold value.
    Once it come down the lower threshold value the output should be stopped.
    2. I want to write this in to a  file and i want to read this file. is this possible or not. 
                please try to help me i am very new with lab view6i

    The easiest way to perform a certain action (such as file I/O) based on a certain condition (such as whether a value has passed a certain threshold) is to use a comparison VI in combination with a case structure. Then you can specify that if your rms, standard deviation and variance are above a threshold then perform a certain action.
    Also consider using shift registers to keep track of data from the last loop. If I understand you correctly, you want to start logging data when an upper threshold has been passed. Then you want to continue logging data until a lower threshold is passed. I have attached a non-functional but explanatory VI that will help explain how to implement logic to that effect. It also demonstrates that you can indeed write and read from the same file in a loop. The best way to do this is to open the file before the loop, do all the necessary writing and reading in the loop, and then close the file after the loop.
    Hope this helps!

  • How to combine both DAQ AI signal, write and read file in single VI

    Hi
     I am the new user of LabVIEW version 7.1 for testing automation application. I have to measure 33 signals ( mostly analog like temp, pressure, etc...) from NI USB 6210 DAQ system and write in master file for future verfication.From real data or from master file back up have to write  one more file if only the signal reaches steady state , which will used for analysis and same signals to be read from this file parallely & make a waveform and/or table display format.
    Pl. help me to shortout this problem 
    note: I have plan to ugrade labVIEW version 2011 shortly, so let me know doing parrel acquistion write and read file for data analysis in same VI in version 7.1...... 

    Parallel operations in LabVIEW are very simple.  Just code it in parallel and it will work.
    Try taking a look at some of the examples in the NI Example Finder (Help > Find Examples).  There you will find example for writing to and reading from files, as well as data acquistion in parallel with other operations.
    You might need a producer/consumer architecture is you are acquiring data very quickly.

  • DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file

    Hi
    DAQ vi to perform digital write and read measurements using 32 bits binary data saved in a file
    Two main
    sections:
    1)     
    Perform
    write and read operations to and fro different spread sheet files, such that
    each file have a single row of 32bits different binary data (analogous to 1D
    array) where the left most bit is the MSB. I don’t want to manually enter the
    32 bits binary data, I want the data written or read just by opening a file
    name saves with the intended data.
          2)     
    And
    by using test patterns implemented using the digital pattern generator or  build digital data functions or otherwise, I need to
    ensure that the     
                binary data written to a spreadsheet file or any supported file type
    then through the NI-USB 6509 is same as the data read.
    I’m aware I can’t use the simulated
    device to read data written to any port but if the write part of the vi works I
    ‘m sure the read part will work on the physical device which I’ll buy later.
    My Plan
    of action
    I’ve
    created a basic write/read file task and a write/read DAQ task for NI USB 6509
    and both combine in a while loop to form a progress VI which I’m confuse of how
    to proceed with the implementation.
    My
    greatest problem is to link both together with the correct functions or operators
    such that there are no syntax/execution errors and thus achieve my intended
    result.
    This
    project is one of my many assignments for my master thesis, so please i’ll
    appreciate every help as I’m not really efficient with LabVIEW programming but
    I prefer it because is fun and interesting if I get to know it.
    Currently I’m
    practicing with LabVIEW 8.6/NI DAQmx 8.8 Demo versions and NI USB 6509
    simulated device.
    Please see
    the attached file for my novice progress, thanks in
    advance for the support

    What does your file look like?  The DAQmx write is expecting a single U32 value, not an array of I64.

  • Closing a serial port after executing a for loop of write and reads.

    Hello,
    Labview is opening and then closing each write to the port. I have tried to leave the close outside of the for loop, but labview wont allow it. What do I need to change to make all the writes and reads execute on 1 open and close of the serial port.?
    Thanks.

    J_es--
         The program that you posted looks to be ok for the most part, you might consider putting an open after your configure (but that's trivial). The other thing that is a minor issue is the loop tunnel coming out of your for loop is currently being auto-indexed.  This function is used to index data for each interation of the loop.  You are using a static address (not an array) and so you don't need this.  If you right-click and remove the auto-index the broken wire will go away. Other than that it should be ok.
         I would suggest looking at one of the shipping examples that come with LabVIEW.  "Basic Serial Read and Write" is essentially the same thing that you are doing and is tested here and might save you a bit of time.  Anyway, take a look if you have a second. Best of luck with your application!

  • Options for having cFP write and read file

    I have a cFP VI that runs on a cFP 2110 controller for doing process automation on a custom piece of equipment.  It seems that each month we use the same equipment for a slightly different automated process routine.  What I have done in the past is to make a copy of my VI's and real-time project and then make the changes in the code for the new process.  Most of the changes to the code between processes are just changes to numeric controllers to change ramp and slope times or the number of times the code repeats a set of steps.  I have been playing around with writing a sort of configurations page to my VI to allow the user to change some numeric controls, save them to a file using the Read Key.VI and Write Key.VI.  In the simple tests I have done, this works If I have a target VI on the cFP 2110 and a host VI where I can have the configurations page and save the file to my computer's hard drive. 
    The configurations file I would create would probably have 15-30 numeric controls and maybe some string commands.  I have a couple of questions about doing this.  Do I need to go back and create both Target and Host VI and communicate between the two using shared variables, or can I just keep my current VI and write a subVI that would save my files to the cFP controller?  If I save the files to the cFP controller, can user set the numeric controller and save the file and/or  likewise call-up any of say one of say 10 differnet files to populate the various sub-VI and run? 
    Finally, provided that I can write and read these small configuration numeric controller files to the controller, is there any advantage to writing the files to one method or the other: writing to the controller vs, creating a target and host VI to load the data?
    Thank you for the help.

    Test read write key.vi ‏58 KB

    StepanieO,
    I finally had a change to play around with the cFP file write and read again.  I was able to write a the cFP and read the file back using write to spreadsheet and read from spreadsheet.  The one problem I can't seem to figure out is how you browse the cFP to select a file.  If I enter the file name and path into the string command it works.  But If I try to browse the cFP, the browse button only shows the computer hard drives.  Is there a way to browse the cFP controller for a specific file?
    Thank you for the help.

    Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.
