• The appeal of java by a button script

  Hello
  
  I have a form and I want to let the end user to confirm an action which was launched by pressing a button. The best way would be to call Java script, but the button is a button 'item' and not a 'region' button - I... e it is placed between the elements and not over the region, as save, cancel etc..
  
  In the case of "item" buttons, I have no "optional URL Redirect" on the ground where to place the javascript call.

  You can try this...

  Instead use the button

  Change the item that you want to associate a button.
  Go to the tab of the element
  Under message text enter element

   Click me
  

  Note: you must change the class = "t20Button", I use the 20 theme and that the appearance of the button is derived from t20Button.

• Could not find iterator of property in the oracle.adfmf.bindings.dbf.AmxCollectionModel class

  I created a RestServiceDescription to a rest Service and "Artifact generation" to create Java objects. With the generated Service, I've created a data control.

  The rest service returns an Array of JSON object. So I tried to create a list view of the DataControl. Now, the error I get is: property in the oracle.adfmf.bindings.dbf.AmxCollectionModel class iterator is not found

  
  

  I don't know what is happening. Can someone help me?

  I found the problem: The REST services had been set up to use localhost, which is not available in the Android emulator. Changing the address to 10.0.2.2 solved this problem.

  I'm a PL/SQL programmer, but not a Java programmer. I have the following java function that does what it's supposed to add a pdf at the end of another pdf document:

  import oracle.sql.BLOB;
  import org.apache.pdfbox.util.PDFMergerUtility;
  import oracle.jdbc.OracleConnection;
  import oracle.jdbc.driver.OracleDriver;
  import java.io.OutputStream;

          //create a connection object to the current instance
            OracleConnection conn = (OracleConnection)new OracleDriver().defaultConnection();
          //create the output blob using the connection
            BLOB outPDF = BLOB.createTemporary(conn, true ,BLOB.DURATION_SESSION);
          //create an output stream to the output blob
            OutputStream os = outPDF.setBinaryStream(0);               
          //instantiate the pdf merger utility
            PDFMergerUtility mergerUtility = new PDFMergerUtility();       
          //connect the merger to the output stream
            mergerUtility.setDestinationStream(os);
          //stream from each input blob into the merger utility
            mergerUtility.addSource(pdfdoc1.getBinaryStream());
            mergerUtility.addSource(pdfdoc2.getBinaryStream());
          //merge the 2 input pdfs
            mergerUtility.mergeDocuments();             
          //do not close the output stream
          //return the blob
          return outPDF;
      }
  
  }
  

  CREATE OR REPLACE package PDFTOOLS.pkg_pdf_utilities
  as
  function f_get_merged_pdf (
            pi_pdf1       blob
          , pi_pdf2    blob
    )
    return blob;
  end pkg_pdf_utilities;
  /
  
  CREATE OR REPLACE package body PDFTOOLS.pkg_pdf_utilities

    'com.mycode.pdftools.PDFUtilities.appendPDF(oracle.sql.BLOB, oracle.sql.BLOB) return oracle.sql.BLOB';
  end PDFTOOLS.pkg_pdf_utilities;
  /
  

  It's very basic, but doesn't seem to work. However, I want to my function from PL/SQL to a procedure that looks like this:

  CREATE OR REPLACE package PDFTOOLS.pkg_pdf_utilities
  as
  procedure sp_append_pdf (
            pio_pdf2append2   IN OUT NOCOPY blob
          , pio_pdf2append   IN OUT NOCOPY blob
    )
  end pkg_pdf_utilities;
  /
  

  What is important, what I'm trying to do is to NOCOPY the BLOBs. Otherwise, I have to read my PDF files into 2 BLOBs and create a 3rd blob as output. I prefer to be able to keep the pio_pdf2append2 as the final output. What I actually do call thing in a loop to gradually add a PDF file to a big. I'm not linking this in one operation because of concerns over the use of the system and because the pdfbox library java has would have been question after 850 in PDF format, which is not completely unrealistic in my approach.

  How could I achieve this?

• Get the value of the bind variable in backing bean class VO Impl

  Hello
  
  I have a VO that includes a bind "pOrgId" variable, the VO has a java VO Impl class that includes:
  
  /**
  * Returns the value of the variable to pOrgId.
  value of the variable * @return for pOrgId
  */
  public {getpOrgId() number
  return (Number) ensureVariableManager () .getVariableValue ("pOrgId");
  }
  
  So it is possible to obtain the value is concluded by the binding variable using this class in a backing bean? (I tried to import the VOImpl class in the bean to support, but getpOrgId is not available?).
  
  (JDEV 11.1.2.3.0)
  
  Concerning
  Carl

  Hello

  When you create a ViewObjectImpl class, none of these options is to generate the getter/setter for bind variable. Create a client class interface and expose the get method for the variable binding. Now, you can reference the method since a binding method in the ADF, which you then access a managed bean by calling

    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    OperationBinding oper = (OperationBinding) bindings.get("name of the method binding");
    Object returnVal = oper.execute();

• Sends the data backend Java

  What is the best way to send a flex object to a java backend and then do something about this on the server? I have a table that contains a custom class. When the user clicks on send, I want to send the picture to Java, then get the content of the table to handle the content and write it to a file.

  I have a remote Java object I want to send the data, in order to manipulate it. I don't think that I need a remote object to represent the purpose of flex, but because that would mean that whatever changes I do object in flex continually is sent to the back-end right? I want to just send it in one appointment once the user has finished editing on the front-end server.

  I found XML serializers that people did that recursively go through the object and create XML. It must then be deserialized on the coast of Java. I thought that there must be an easier way. Is there a library or something for this?

  Perhaps, I do not understand the reason for your implementation so don't take no not this personally.  But why would you send a Canvas object, which is part of the view on the server?  If you are only wanting to send the data contained in the text to the server for processing objects you want to do is create a ValueObject (TransferObject for some) and send it to the server, as well as perhaps instructions you want to send.

  On the other hand (and this is just a blind guess at what you're trying) If you are wanting to send the objects so that you can implement some sort of compilation side server, then you want to send the object to plain text for the Web as one of the settings contained in your ValueObject.  Alternatively, you can use Adobe AIR and zip all of the defined object and send the file to the server where it can be decompressed and compiled.

  Here is a blog post on data transfer between Java and Flex using RemoteClass.

  ATA-transfer-objects-from-Java-to-Flex/ http://pachamuthu.wordpress.com/2009/07/15/using-BlazeDS-to-Send-User-Defined-Data-types-d

  I hope this helps.  If this isn't the case, then perhaps a little more information on what you are trying to accomplish might help.

• the use of java 1.5 IS not permitted in JDev 11.1.1.1

  I use JDeveloper 11.1.1.1, and I created my project to use java 1.5.0_11 SE.
  When I build the project I get in the Log of the compiler: error: project is not configured to use at least JDK 6.
  Why is that? How to avoid this?
  TIA,

  Hi Aurel,

  I think you need to use the JDK 6 If you plan to use JDev 11 g. Don't think that there are other ways around that. I can't find sources that explicitly stated that JDK 5 is not well supported, but the error message you provided stated very clearly-* "project is not configured to use at least JDK 6." *
  http://download.Oracle.com/docs/CD/E12839_01/install.1111/e13666/ojdig.htm#BDCDAGAH

• Run the jar using Java 7?

  I don't have any Java installed for an exact string to show you, but each version of Java is installed in its own folder. You can call this version of Java by specifying the full path to the particular version.
