exception in getting the blob into byte]

HY guys,.
I have a problem with my java application.
I use hibernate to interact with a derby database.
I've stored an image into the blob field (and not a problem).
When I try to get the blob into byte array that I have this exception:
java.sql.SQLException: You cannot invoke other java.sql.Clob/java.sql.Blob methods after calling the free() method or after the Blob/Clob's transaction has been committed or rolled back.
To get the BLOB I made
Blob cThumnb = ((Allegato) cAllegati.get(i)).getThumb();
byte[] cPrev = toByteArray(cThumnb);
where
private byte[] toByteArray(Blob fromBlob) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        try {
            return toByteArrayImpl(fromBlob, baos);
        }
        catch (SQLException e)
        {
            throw new RuntimeException(e);
        }
        catch (IOException e)
        {
            throw new RuntimeException(e);
        }
        finally
        {
            if (baos != null)
            {
                try
                {
                    baos.close();
                }
                catch (IOException ex)
                {
                }
            }
        }
    }

    private byte[] toByteArrayImpl(Blob fromBlob, ByteArrayOutputStream baos)  throws SQLException, IOException
    {
        byte[] buf = new byte[4000];
        
        InputStream is = fromBlob.getBinaryStream();
        try
        {
            for (;;)
            {
                int dataSize = is.read(buf);
                if (dataSize == -1)     break;
                baos.write(buf, 0, dataSize);
            }
        }
        catch(IOException ex)
        {
                throw ex;
        }
        
       finally
        {
            if (is != null)
            {
                try
                {
                    is.close();
                }
                catch (IOException ex)
                {
                }
            }
        }
                return  buf;// baos.toByteArray();
    }
Could you help me?
I define also autocommit to false.
Thank you
Concerning

java.sql.SQLException: you can't call other methods of java.sql.Clob/java.sql.Blob after the free() method is called or after the transaction of the Blob/Clob object has been committed or rolled back.

So invoke it before calling the free() method or until the transaction has been committed or canceled?

And why the blob in an array of bytes to all? The idea of blobs is you don't know what size they are and how you treat the content as a stream.

    You call a LiveCycle orchestration? If Yes, then you would define a string as an input parameter (make sure you so there is no time limit). Then when you call the function, the string contains the content encoded in base64 in your PDF. You must enter this in a document variable so in a setValue operation you can assign it to a VAR of document using this function:

    getDocFromBase64

  • Trying to get ending entry into force for the groups of lines

    Hello world

    I searched the forums, but I can't find a post that is a problem quite like that.

    I have some data that looks like this:
            ID_NUM     EFFECTIVE ALLOC_PERCENT   ACCT
---------- --------- -------------   ----
       101 01-JUL-11            21   A1
       101 01-JUL-11            72   A2
       101 01-JUL-11             7   A3

       101 01-JUL-12            20   B1
       101 01-JUL-12            80   B2

       101 01-JAN-13            20   A1
       101 01-JAN-13            20   A2
       101 01-JAN-13            50   A3
       101 01-JAN-13            10   B1

       101 01-JUN-13            50   A1
       101 01-JUN-13            50   A2
    (note: I inserted manually empty lines for clarity)

    Here's the logic: the lines represent an assignment of percentage on the account for the identification number specified for this entry into force. A new date to cancel the previous, and if any line in the conceptual group is replaced, so they are all.

    I'll try to find the date when the effective period of each group ended and which includes in the game so that I can calculate then the number of days in a given line has been effective; something like that;
      ID_NUM     EFFECTIVE END_DATE   ALLOC_PERCENT ACCT
---------- --------- ---------- ------------- ----
       101 01-JUL-11 01-JUL-12             21 A1
       101 01-JUL-11 01-JUL-12             72 A2
       101 01-JUL-11 01-JUL-12              7 A3

       101 01-JUL-12 01-JAN-13             20 B1
       101 01-JUL-12 01-JAN-13             80 B2

       101 01-JAN-13 01-JUN-13             20 A1
       101 01-JAN-13 01-JUN-13             20 A2
       101 01-JAN-13 01-JUN-13             50 A3
       101 01-JAN-13 01-JUN-13             10 B1

       101 01-JUN-13 <null>                50 A1
       101 01-JUN-13 <null>                50 A2
    The end_date of the group is the EFFECTIVE_DATE of the next group (ordered by ID_NUM, EFFECTIVE_DATE).

    End_date of two rows is zero because there is no group of lines with an effective date the later - in my process, I'll NVL which sysdate so that my calculations of days will be valid.

    I tried some analytical queries with LEAD, but I couldn't figure out how to get the next date of the efficient group. I could get the entry into force of the next row, but not the next group. I couldn't specify how many lead lines to look forward, because there is not a number of rows in each group.

    How to fill the end_date column?

    Here's the code to create the above.
    create table t
(id_num number,
 effective_date date,
 alloc_percent number,
 acct_code varchar2(4)
 );

insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jul-2011',21.0,'A1');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jul-2011',72.0,'A2'); 
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jul-2011',7.0,'A3');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jul-2012',20.0,'B1');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jul-2012',80.0,'B2');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jan-2013',20.0,'A1');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jan-2013',20.0,'A2');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jan-2013',50.0,'A3');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jan-2013',10.0,'B1');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jun-2013',50.0,'A1');
insert into t (id_num,Effective_date,alloc_percent,acct_code) values(101,'01-jun-2013',50.0,'A2');

  • Get the network traffic in bytes

    I try to get the number of bytes to pass by the network interface.

    The code I use is:

    String [] interfaceList = this.proxy.getNetInterfaceList ();
    a long time in = 0L;
    long out = 0L;

    for (String inteface: interfaceList) {}
    log. Debug (inteface);
    NetInterfaceStat netsstat = this.proxy.getNetInterfaceStat (inteface);
    in += netsstat.getRxBytes ();
    on += netsstat.getTxBytes ();
    }

    I'm not sure that I do it well, because the figures are not updated often. For example, I download a movie from youTube and the number does not change. I have to wait 30 seconds before it changes. Is the resolution of a minimum amount of time (on Windows 2000 Pro) is 30 seconds?

    Hi James,

    I saw this.proxy in your code, guess that is an instance of SigarProxyCache?  This class is a wrapper for caching the values returned by the underlying class of Sigar, 30 seconds by default.  You can change this value by default, but it seems you'd be better of just using the new Sigar() straight-up instead of the ProxyCache.

  • Another problem in the BLOB view

    Hi all

    I have a problem in the image display on the screen. Here's my situation: I have an Oracle table, consists of string, CLOB and BLOB. I also have a web application using JSP and Servlet. My Blackberry application will access the servlet to get the data in my table. Returns an XML file, not a file JSP, servlet, then my Blackberry application will read this file, it displays on the screen. I use not BrowserField.

    My problem is... How can I display the image?

    I have tried to convert byteArray BLOB, and then again to convert to a string, inserting it into my XML. In my Blackberry app, get the string and convert it to byteArray and then use

    Bitmap.createBitmapFromBytes to get the Bitmap image. But it gives me nothing.

    Can someone help me?

    Thank you much in advance.

    Kind regards

    Novan Ananda

    I offer two General options:

    1 generate and send an image url to the XML format. Request per second to get the bytes of the images to the server. Server can presave the image in a temp folder or get the blob of the DB directly.

    2 send the image data as xml encoded in base64. Decode the device and view EncodedImage.

    I prefer the method if you send pictures not only in response. Can see the context for your asynchronous image download information.

    Thank you

  • Write the blob value in a file

    Hi all


    I'm looking on the correct method of writing a blob value to a file. I know the best way to use an external language. For example, Java or C. But also, I met a number of solutions to do within pl/SQL block. All of them look like this:


    CREATE OR REPLACE PROCEDURE Write_Binary_file
    (
    PC$ Directory IN VARCHAR2
    , PC$ file_name IN VARCHAR2
    , PC$ SQL_Order IN VARCHAR2

    )
    -- -------------------------------------------
    -Procedure to empty a BLOB column in a file
    -- -------------------------------------------
    -settings:
    -PC$ Directory: name of an existing directory of Oracle
    -PC$ file_name: name of the file output expected
    -PC$ SQL_Order: SQL command to select the BLOB column
    -PB$ Raise: boolean to indicate if the process
    -would be stopped after an error
    --
    IS
    src_lob BLOB;
    RAW buffer (16384).
    AMT directory: = 16384;
    INTEGER POS: = 1;
    LF$ FicOUT UTL_FILE. TYPE_DE_FICHIER;
    LC$ Msg VARCHAR2 (2000);
    BEGIN

    -get the BLOB column-
    BEGIN
    EXECUTE IMMEDIATE PC$ SQL_Order IN src_lob;
    EXCEPTION
    WHEN NO_DATA_FOUND THEN
    LC$ Msg: = ' Write_Binary_File(): NO_DATA_FOUND';
    If PB$ increase THEN
    RAISE_APPLICATION_ERROR (-20100, LC$ Msg);
    END IF;
    Dbms_Output.put_line(LC$MSG);
    RETURN;
    END;

    -Open the output file-
    LF$ FicOUT: = UTL_FILE. FOPEN (Directory$ PC, PC$ filename, 'W', 32764);

    -write the file-
    LOOP
    -play songs-
    Dbms_Lob.read (src_lob, amt, pos, buffer);
    -write the songs-
    Utl_File.Put_Raw (LF$ FicOut, buffer);
    POS: = pos + amt;
    END LOOP;
    -Close the file-
    Utl_File.fclose(LF$FicOut);

    EXCEPTION
    WHEN NO_DATA_FOUND THEN
    UTL_FILE.fclose(LF$FicOut);
    WHILE OTHERS THEN
    LC$ Msg: = ' error Write_Binary_File(): ' | TO_CHAR (SQLCODE) | "everything by managing the file (')"

    END IF;
    Dbms_Output.put_line(LC$MSG);
    END Write_Binary_file;
    /


    But this code doesn't seem to work. The problem is that it always creates a slightly bigger than an initial file. So copy jpg will never be opened with any viewer.

    Can someone explain this problem and give no work around?

    Thank you

    Hello

    If I look at this procedure, I think that you forget to check if the last part, it takes to read is less than 32000. Now you put the always full buffer to the desired quantity. The last part, you only need to read from the BLOB what remains, nothing more. By reading more, get your blob of larger than expected.
