• Create the object type with a member function that returns an array of the object type

  Hello

  Is possible to compile code like this in Oracle SQL?

  CREATE OR REPLACE TYPE type_obj IS OBJECT (
    MEMBER FUNCTION f RETURN table_obj
  );
  
  CREATE OR REPLACE TYPE table_obj AS TABLE OF type_obj;
  
  

  In Java, it would be possible.

  Thanks in advance

  Circular dependencies must be resolved by means of REF pointers and incomplete type definition.

  See: Oracle objects management

  CREATE or REPLACE TYPE type_obj;

  /

  CREATE or REPLACE TYPE table_obj AS TABLE OF ref type_obj;

  /

  CREATE or REPLACE TYPE type_obj () IS OBJECT

  fake number

  Table_obj RETURN of the FUNCTION MEMBER f

  );

  /

  Now, it must implement the body of type.

  Note that a table of the REFs is not very useful in the plain of PL/SQL, the underlying data must be stored in a nested table if you want to use.

  http://wiki.answers.com/Q/Can_you_call_a_java_function_from_an_oracle_stored_procedure

• Call the JavaScript file java class in the native blackberry development.

  
  

  What you are looking for is the ScriptableFunction class.

  You can extend the script engine of a JavaScript object name to a ScriptableFunction Java class mapping.  In this example, if you called foo. JavaScript bar(), the BrowserField would facilitate a call to the invoke() method defined in the MyScriptableFunction() class:

  protected BrowserField _browserField   = null;
  _browserField = new BrowserField();
  _browserField.extendScriptEngine("foo.Bar", new MyScriptableFunction());
  

  Then you set your ScriptableFunction class like this and fill it with some Java code, you need.  Note: it only accepts strings as input parameters.

  import net.rim.device.api.script.ScriptableFunction;
  
  /**
   * @description Demonstration of using the ScriptableFunction class added to version 5.0 of the BlackBerry Device
   *              Software

   */
  
  /**

   */
  public class MyScriptableFunction extends ScriptableFunction
  {
  
      /**
       * User has invoked this ScriptableFunction from the JavaScript engine This example shows how to open the Messages

       */
      public Object invoke(Object obj, Object[] args) throws Exception
      {
          if (args.length == 3)
          {
  
              String param1 = args[0].toString();
              String param2 = args[1].toString();
              String param3 = args[2].toString();
  
              //Do something

• Java class to connect to Oracle Database Express Edition11g and URL

  Can I use Oracle SQL Developer to do or use it as the value of the URL for the host name?

  I'm just starting to learn Java and with it, learn how to use the Oracle Database Express Edition11g and with it the Oracle SQL Developer...

  At this point, I have the Express Edition is installed and the SQL Developer installed and were able to establish a connection and to run a query and get a result.

  I use Eclipse for JAVA.  I have a work of class that performs a query on a database/table in MySQL.

  So now I'm eager to make the same use as the database Oracle Database Express Edition11g engine.

  And this means that two different versions of JAVA that I need to get the right to be able to do.

  The first is the value of the url variable.

  I now like

  String url = "jdbc:oracle:thin:@localhost";

  then

  Class.forName ("oracle.jdbc.OracleDriver");

  and then

  Connection connection = DriverManager.getConnection (url);

  The thing I'm puzzled on is in the URL where I 'localhost' was supposed to be the term generic and not so much as the text, you should use.

  I see in Web sites like 3 connection to Oracle Database XE

  and decrease example 3-2 by specifying the URL of database using the XE Client Setup

  There I see

  JDBC:driver_type: [username/password] @[//]host_name[: port] [XE]]

  And just what is and what is not is explained here.  So what I ended up with was

  String url = "jdbc:oracle:thin:@localhost";

  So if it was just a text to rest for a name I wonder just such a value or name might really where.

  I noticed that view that an app called "Oracle JDeveloper" has been used to create the values.   I don't have such a thing, or at least I don't think I do.

  Do I need?

  I have Oracle SQL DEVELOPER, where I used the following to connect to the database of the XE.

  My choice for Oracle's SQL Developer Help

  Name of connection: Connection1

  User name: Rod

  Password: myOracle11

  Host name: localhost

  Port: 1521, which is the default value

  SID: xe

  Above so I have to host name set to localhost

  Can I use Oracle SQL Developer to do or use it as the value of the URL for the host name?

  1. I do nothing

  2. While wouldn't you say it

  3. no results from the earlier assignment.

  I asked "'can I use Oracle SQL Developer to do or use it as the value of the URL for the host name?" "

  I showed the choice that I used in SQL Developer to connect to the schema.  And I was wondering, now that I had done this case those are the values that I could use in the Java class that I wrote.  The web site in the first post of this thread showed connection but he was using JDeveloper and SQL Developer.

  So I was wondering if the connection that I made using SQL Developer would do the same trick, and if I could use the values I did there.

  I'm happy to announce that YES, The values used to connect using SQL Developer work exactly like JDeveloper.

  So, given that in SQL Developer for Hostname I chose the value "localhost" "Rod" Username and password "myOracle11".

  I did the following JAVA CLASS that worked:

  package VC_2_9;

  Java for COBOL - copyright 1999 Doke & Hardgrave programmer

  import java.sql. *;

  / * String sqlQuery = "SELECT Name, SSNo, address, telephone OF THE customer;    */

  String sqlQuery = "SELECT CUST_LAST_NAME FROM DEMO_CUSTOMERS";

  //                                               |||||||||||||||

  Try

  {

  Class.forName ("oracle.jdbc.OracleDriver");

  Connection connection = DriverManager.getConnection (url, "Rod","myOracle11" ");

  Statement statement = aConnection.createStatement ();

  ResultSet rs = aStatement.executeQuery (sqlQuery);

  Boolean more = rs.next ();

  (more)

  {

  CUST_LAST_NAME = rs.getString (1);

  /* */

  System.out.println ("name:" + CUST_LAST_NAME);

  more = rs.next ();

  }

  RS. Close();

  aStatement.close ();

  aConnection.close ();

  }

  catch (ClassNotFoundException e)

  {System.out.println ("Exception caught" + e) ;}}

  catch (SQLException e)

  {If (e! = null)}

  {System.out.println ("SQLException taking" + e);}

  e = e.getNextException ();

  } / / end of while loop

  The correct syntax for PORCEDURE4 is:

  No it's not. I already gave the correct syntax, which apparently ignored you.

  I don't know how can pass these parameters to this method.

  My question is clear?

  It is clear that you are interested in reading the documentation. All the answers are there.

  You're mixing two things:

  (1) creating the procedure (once), and I already told you how to do it

  (2) the procedure call

  For 1)-do you only once :

  CREATE OR REPLACE PROCEDURE REPORT4)

  LEVELS IN NUMBERS

  NODEID NUMBER

  CHILDBED_OLD NUMBER

  CHILDBES_OLD NUMBER

  CHILDMANDE_OLD NUMBER

  )

  AS

  JAVA LANGUAGE

  NAME of ' oracletree1. TREEUPDATER.updating (int, int, int, int, int)';

  For 2)-procedure call:

  ...

  BEGIN

  ... of the code

  -you call proc with your real settings:

  procedure4 (v_levels, v_nodeid, v_childbed_old, v_childbes_old, v_childmande_old);

  ... rest of your code

  END;

  each of the components of UI forms made. Magic
  lies in the fact that, since each component of the interface user is, indeed,
  a Java class, it can be subclassed. This means that you can
  create your own component that does all the
  component base, but with your own code to change
  the functionality or appearance.
  
  Really a piece of gold, in this regard, it will give you the key can change the forms look & feel.
  
  But, now, come the questions, how can I do this? How do I know what forms of using classes to display a button for example, what I need to do for subclasses?
  is there an example or documentation that can help me? If yes ¿where? One of the gurus can give me some links to explore this?
  
  Thank you & considers everyone.

  Look at this.

  It is not supported by Oracle, but is widely used. All support for its use will come from its web page.

• When the external program C and Java Class loaded in a schema

  Hi all
  I understand that both an external C program and a Java class are loaded after two of them are called in the PL/SQL environment, once they are published and loaded into shared libraries. Is this correct?
  
  Best regards
  Val

  An external procedure is never loaded into a schema. Oracle calls the external program.

  A Java class that is part of a Java stored procedure, however, is charged as a PL/SQL procedure is created - at compile time.

• How to pass values from a Java class to a class of JavaFX?

  Hi Forum,
  I get nuts on this problem:
  I designed a program with Java and JavaFX classes. JavaFX classes handle the GUI and Java classes mix program logic. I think that's the way it is supposed to be. My program calculates something, so in my JavaFX GUI, I have a button to run this calculation. It's not a problem to call the start function calculation (which is in my Java class) on click of a button. But now I want to display the result of this calculation in my GUI. I can't just simply pass the result to my class of JavaFX GUI. I tried to import the JavaFX class in my Java class to call a set function, but I can't import them with the import statement. So my question is, how do I make the results to my GUI? What is the right way to do it?
  I hope someone can help, thanks in advance :)

  Two ways, either:

  -your JavaFX class asks the Java class for the result once the task completed in exactly the same way he instantiated to start the task. Of course, you should regularly check the completion of the task (a mere PauseTransition).

  - or your JavaFX class implements a Java INTERFACE and your Java class accepts (whether through the method or constructor) a variable of type of this interface. For example, you can set a reference to the subject of JavaFX itself in the Java object using the interface.
  When the task is completed, your Java class calls a method defined in the INTERFACE to set the result in the object of JavaFX.

  In addition, JavaFX 1.3.x provides an API to start asynchronous and be notified when a task is completed in the javafx.async package that allows you to run the task of basic Java (you mind that the class is named...) JavaTaskBase, see also the RunnableFutre interface) in a separate thread.
