Encoding, get ASCII as default encoding

Hi,
I'm using Linux (Red Hat 8), where I have installed Java .1.4. Now when I try to parse xml feed from request.inputStream im getting wrong encoding values.
Im storing all the xmlfeeds when i receive on seperate files, but when I get the encoding for the files I get ASCII. Doesn't java have UTF-8 as default encoding? Even thought I have explicitly told that the input is utf-8 (request.setEncoding ("utf-8")) it does not work.
Therefore im getting wrong values stored on the database (utf-8 tables).
Where is the default encoding ASCII come from ?
Can anyone please answer..

thank you for the replay,
After your advise im now being more strict about encoding to utf-8. Im doing following:
1. setting request to utf-8 explicitly. request.setCaracterEncoding("utf"))2. opening bufferedStreamReader with encoding parm.
with request.getInputStreamreader
String xmlString = null
String line;
BufferedReader reader = new BufferedReader(new InputStreamReader(
                         request.getInputStream(),"UTF-8"));
     while ((line = reader.readLine()) != null) {
               xmlString += line + "\r\n";
     }3. Then dump the string to a file to verify that i got the right encoding:
File f = new File ("out.xml");
            FileOutputStream fos = null;
            OutputStreamWriter out = null;
     fos = new FileOutputStream(f);
     out = new OutputStreamWriter(fos, "UTF-8");
           Writer w =  new BufferedWriter(out);
     w.write(xmlString);           4. when i finally take upload on the out.xml file from Linux server to windows os, open the file i get non-ascii character to be ??. The copyright character get ??. Do i do anything wrong, or can it bee that im missing some lib for the redhad distribution?

  • Opening Build Specificat​ion - Error 7 occurred at Get LV Class Default Value.vi

    I recently ported my project to a new PC. Everything seems to run fine uncompiled, and I am able to build an executable without issue. However, my build specification shows up in the project explorer with question mark next to it. When I try to build again or edit the properties I get a popup with the information below:

    I've seen messages from people getting the same error when trying to run a compiled executable, but mine actually runs fine. I am just unable to open the build specification to rebuild or edit its properties.

    This application is for a Windows machine, and I am not using the Report Generation Toolkit. However, I shut down my computer last night and when I booted it up this morning my Build Specification now opens fine and I am able to edit it. My only thought as to why it occured in the first place is that I had added several files to user.lib and instr.lib and restarted LabVIEW, but it appears that it required my computer to be restarted as well.

  • Error 7 occurred at Get LV Class Default Value.vi only in my executable for Print Report - LV 2010 SP1

    I have a program written which uses the print report function. Everything works fine in the uncompiled code, my report prints just fine. I can compile my project all the way to a full installer. When I run the executable I get the error:

I get no warning when I compile this to an executable. I already tried repairing both LV SP1 and the report generator toolkit. No change after I compile to an exe.
    Any help would be appreciated. Thanks.

  • How to get or set default fiscal year value in billing doc

    Hi All, my question is simple, how to get or set default fiscal year value (VBRK_GJAHR) in billing document.. is it possible.
    Thanks.
    Regards,
    Michael

    Hi Michel
    If you feel that the fiscal year value should come  in the billing document then you have to use a user exit USEREXIT_NUMBER_RANGE .
    As this is a related to ABAP , you should give the inputs and ABAP'ers will give the number range as per our requirement .

  • Manual item category gets overridden by default item category

    When I enter a manual item category for a material  in a sales order, it gets overwritten by the default item category maintained in VOV4 (maintained for the order type and item category group. This is in ECC6. It is working in 4.7 though. How do we permit the manuaul item category to be entered and not get overwritten by default item category?

    Hi,
    You have not mentioned in VOV4, manual item category has been maintained or not. Can you check the values are maintained in those column?
    Also in the debug mode, you can check whether any user exit is restricting this.

  • Why can't I use Get LV Class Default Value in a dynamic VI?

    I am attempting to override a VI that uses "Get LV Class Default Value" and getting an error that I don't understand.  My parent class, "ANT Message Class", has two children - "ANT Command Class" and "ANT Response Class".  The children share a lot of data and functionality, including the factory pattern that the parent class' "Load Message Class" VI implements (see image).  I would like to override this VI with a Command version and a Response version, which would simply call the Message version with their respective classes overriding the dynamic input and output terminals.  However, I am getting the error "Front Panel Terminal 'ANT Message Class Out': Run-time type not propagated from dynamic input to dynamic output."
    Not sure how to get around this one.  Any ideas?
    Thanks,

    The To More Specific node is dealing with compile-type inference. In this case, you are loading a default instance from disk and then attempting to cast to the base Message class. However the type you are casting to is going to a dynamic output - this gives the compiler no assurances that the input class at run-time on the dynamic input will be the same as the output type; only that it will be a type at the top of the hierarchy. Dyanmic dispatch inputs/outputs must be the same type to guarantee some form of type safety.
    You need the Preserve node there so that you can guarantee the class at both dynamic dispatch terminals will be the same type.
    However this is probably not the best mechanism for a factory method. Factory methods should ideally be static; their job is to provide an instance of the right type (e.g loaded by path as per your example) and you don't need an instance of a class to do that. The only reason I can think of to over-ride said functionailty in a dynamic dispatch method is to provide some form of custom construction for the creation of the type. If all you are creating is an instance with nothing but the default private data then there is no reason to over-ride in the child classes.

    running 10.4.11 finder window too large need to get lbak to default.

    Hi again BDA...
    I'm not certain if it will work on other windows. I am more concerned with it working with the Firefox interface and did not try it on an alternate window.
    On Sep 4, 2012 2:47 PM    (in response to Alexander_Apple) you said:
    "Firefox uses it own settings & Method for that"
    That does make sense which is why I asked if any of the Mac gurus know where in Firefox I go to change the setting. I wasn't really keen on adding another 3rd-party app to my machine. There must be a simpler route to take. Maybe change a preference in Firefox 3.6.28 or in the Displays Preferences? My display is a Samsung LED monitor Model NO. SMBX2235. My Displays Preferences are: "1920 x 1080 @ 60 HZ (NTSC) Millions" but, having not changed them since first setting up the monitor, I'm fairly certain it's not the Displays Preferences. Is there a chance I hit a Function key plus a letter or number one day when typing? I don't recall doing so.
    Thanks for all  your suggestions BDA. I find  it's a bit confusing when you type the word "Windows" with an uppercase "W". Windows to me is something used on an IBM compatible computer. I, personally, do not consider one computer to be better than another. They each have their own advantages and disadvantages and  each type of machine can handle certain apps better than the other machine.
    Thanks again BDA. I hope you have a great day!

  • Please can someone help me to get back the default colours on my mac book pro

    Help can anyone out there please help me get back the default colour settings on my mac book pro!

    Hi, thank you very much for your reply. I finally found out how to solve the problem. In System Preferences you go into Accesibilities and then you have to uncheck the box for Invert colour, somehow this got checked (no idea how!) anyway if checked all the colours go weird and photos & pics look like negatives. So I hope this will help other people too if they ever get this problem.
