• 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)

  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.

• How can I get the contents of an object of Document (XMLDOM) in a string variable?

  Hello

  I created an XML document by using the Document and XMLElement classes and now I need to get the XML object and a string variable, so I can send by e-mail.

  I'm on 4.5 JDE

  Help!

  Hello

  Unlike some other posts, there is a solution.

  Document myDocument = pdocXMLDocument;  / * This is the document that you created that you want to convert to a string

  ByteArrayOutputStream OS = new ByteArrayOutputStream(); / * where you want the XML to go * /;
  XMLWriter writer = new XMLWriter (os);

  configure as you want using one or more of:
  writer.setPrettyPrint (); or setPrintCompressedOutput();
  writer.setPrintCompressedOutput ();
  writer.setPreserveSpacing ();
  writer.setExpandingEntities (boolean);
  writer.setEntityResolver (EntityResolver);
  try {}
  DOMInternalRepresentation.parse (pdocXMLDocument, writer);
  String myXML = os.toString ();        THIS IS THE STRING
  }
  catch (Exception ex) {}
  }

• Get the UID of an object created from a script

  Hi all

  In my script, I create an object in a script (say PersonHasRessource) using the. Save() method.

  Is there a way I can get the UID of the object created in the same script to move to the next step in the process?

  Thank you

  Hello

  PersonHasRessource does not have a UID of its own.  There the UID of the person and the UID of the resource.  So in this case you should already have these values if you have created an entry in this table.

  Here's an example of another table:

  UIDValue = Connection.GetSingleProperty ("AccProductGroup", "UID_AccProductGroup", f.Comparison ("Ident_AccProductGroup", Ident_AccProductGroup, ValType.String, CompareOperator.Equal, FormatterOptions.None))

  So here, I get the UID_AccProductGroup of the AccProductGroup has just created using the Ident_AccProductGroup in the where clause.

• Get the values and elements of object property

  If I have an object,

  MyObject = ({a: 3, b:5, c:8})})

  How can I get a list of items and their values according to their position

  Let's say I want to know what the name of the second element, how can I get the answer "b"?

  In addition, without knowing the name of the element how can I get the value of the second item "5"?

  Thank you

  Trevor

  It is, of course, a matter of Javascript, and the answer is not specific to InDesign, but I think you knew that already.

  The short answer is: you do not have. JavaScript does not have something on the positioning of the members of an object.

  There is no guarantee that b will remain the second element, and there is no way to get the members of an object by a sort of index rather than by their name.

  BTW, you write:

  MyObject = ({a: 3, b:5, c:8})})

  Which is too complex (extra parens) and missing a semicolon from the finish line. It is better written as:

  MyObject = {a: 3, b:5, c:8};

  You can iterate through the names of the keys of myObject, with i in myObject {...}, but still there is no guarantee of order. In ExtendScript, you could use myObject.reflect.properties to return the keys in a table, but you will get some extra junk and it's not really consider good practices to use the objects of reflection in non debug code.

  If you are wanting to do this, you are probably not using objects correctly.

  Can you tell us more about the problem you are trying to solve, please?

• 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

• Unable to get the Session of UserSessionService string in VCenter 6.0?

  Hi all

  I recently moved to VCenter VCenter 5.5 6.0. In my plugin VCenter 5.5 code, I used to get the "SessionString" of UserSessionService object.

  ServiceInstance serviceInstance is new ServiceInstance (new URL (serviceUrl), sessionString, true);.

• 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
  , PB$ Raise IN DEFAULT BOOLEAN FALSE
  )
  -- -------------------------------------------
  -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 (')"
  || PC$ Directory | ') ' || PC$ file_name;
  If PB$ increase THEN
  RAISE_APPLICATION_ERROR (-20100, LC$ Msg);
  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.

• Get the name and the data type into an object?

  Hello

  I would like to know if there is a way to get the names and the types of data encapsulated in an object of labview?

  For example, let's say I make a simple object, called myObject to be commonplace, with private data: myObjectName (string), myObjectValue (int 32) (etc.)

  So, how to build a method to return the type of the data of myObjectValue, or infact back the names and types of all data in the object field, which could be a lot?

  Thank you

  Paul.
