Beginning Objective-C 2.0
I am new to software development and I would like to beginning programming in Cocoa.
I have downloaded Apple's Objective-C 2.0 Tutorial from the Developer Connection website, and I plan to read it before I begin reading a Cocoa tutorial written by Aaron Hillegass.
I currently only have knowledge of Java, and no prior experience with C. This means that I only have a background in object-oriented programming, as opposed to C, which is procedural.
Will I be able to comprehend Apple's tutorial? Should I obtain some knowledge on C before I begin reading the tutorial? Or should my knowledge of Java suffice?
Thank you!
The following links tell you about some of the improvements in ObjC 2.0 - I don't think that there is a lot to learn in addition to the "prior version" but some of the improvements are extremely nice to work with…

Varray of Objects "Bind variable not declared" error.. I don't want a bind variable.
Hello.
This program is supposed to pull values from a table using a loop, and in the loop, put the values in objects in a varray. I'm new to objects and am stumped trying to get this program to run. When I attempt to run it in SQL*Plus I get the following feedback:
Type created.
Type body created
SP2-0552: Bind variable "MY_VARRAY_EMP1" not declared.
I don't think I even need a bind variable. Any feedback would be appreciated. Here's the program:
-- Enable screen I/O

Add a user-defined constructor which takes all attributes and calls the "setter" procedures in one trip:

set VERIFY off
-- begin object spec
create or replace type employee3 as object

constructor function employee3(
self in out nocopy employee3,

aEmpNo in integer,
aSal in number
return self as result,
member function get_ename return CHAR, member procedure set_ename (SELF in out nocopy employee3, ename in char),
member function get_empno return NUMBER, member procedure set_empno (SELF in out nocopy employee3, empno in integer),
member function get_sal return NUMBER, member procedure set_sal (SELF in out nocopy employee3, sal in integer)
-- begin object body
create or replace type body employee3 as
constructor function employee3(
self in out nocopy employee3,
aEname in char,
aEmpNo in integer,
aSal in number
return self as result
is
begin
self.set_ename(aEname);
self.set_empno(aEmpNo);
self.set_sal(aSal);
return;
end;
-- gets
member function get_ename return CHAR is
begin
return self.ename;
end;
member function get_empno return NUMBER is
begin
return self.empno;
end;
member function get_sal return NUMBER is
begin

end;
-- sets
member procedure set_ename(SELF in out employee3, ename in char) is
begin
self.ename := ename;
end;
member procedure set_empno(SELF in out employee3, empno in integer) is
begin
self.empno := empno;
end;
member procedure set_sal(SELF in out employee3, sal in integer) is
begin

end;
end;
(Since I don't have EMP handy at the moment, create a simple view instead)
create or replace view emp
as
select 'EMP' || to_char(level) ename
, level + 100 empno
, DBMS_RANDOM.VALUE(25000,75000) sal
from DUAL
connect by
level <= 20
Get rid of your loop and individual SELECTs, and replace it with a single SELECT BULK COLLECT INTO...
declare
type emp_varray is varray(10) of EMPLOYEE3;
my_varray_emp1 EMP_VARRAY;
this_object EMPLOYEE3;
begin
-- No need for a loop. Use SELECT BULK COLLECT INTO, together with a user-defined constructor call (since the

aEmpNo => e.empno,
aSal => e.sal
bulk collect into
my_varray_emp1

where rownum <= 10;
-- Use another loop to display the information in the reverse order.

Hello,
I am starting to look into how to work with graphics in Java for the first time. So what I am trying to achieve is a simple circle moving across a frame.
Here is the code that I thought would do the trick.
package com.game.begin;
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Begin extends JPanel
int x_pos = 10;
int y_pos = 100;
int radius = 20;
JFrame f = new JFrame();
public static void main(String[] args){
Begin b=new Begin();
b.doRun();
public void doRun(){
f.setSize(600,600 + 20);
f.setVisible(true);
f.setTitle("Do Title");
f.setContentPane(new Begin());
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// Graphics g=f.getGraphics();
while (true){
x_pos ++;
System.out.println("x="+x_pos+" y="+y_pos);
repaint();
// paint(g);
try {
Thread.sleep (10);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
public void paint (Graphics g)
System.out.println("paint method of my thread..............");
g.setColor (Color.red);
g.fillOval (x_pos - radius, y_pos - radius, 2 * radius, 2 * radius);
}However all I get is a circle. It doesn't move across a screen. When I uncomment
// Graphics g=f.getGraphics();and
// paint(g);lines . I get a big red line moving across the screen. Basically I draw a new circle without erasing an old one. My understanding is that if I utilize repaint method Java will automatically erase old graphic and replace with the new one.
I am not sure why in my case this doesn't happen. Can you explain what's going on and/or correct the above code?
Thank you.import java.awt.*;
import javax.swing.*;
public class Begin extends JPanel
int x_pos = 10;
int y_pos = 100;
int radius = 20;
JFrame f = new JFrame();
public static void main(String[] args){
Begin b=new Begin();
b.doRun();
public void doRun(){
f.setSize(600,600 + 20);
f.setVisible(true);
f.setTitle("Do Title");
// Why create a new Begin object?
f.setContentPane(this);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
// Never do this! Have the code render only when asked to do so.
// Graphics g=f.getGraphics();
while (true){
x_pos ++;
System.out.println("x="+x_pos+" y="+y_pos);
repaint();
try {
// It is bad practice to block the EDT. Invoke this loop from a Timer instead.
Thread.sleep (10);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
// Call paint() for AWT. Call paintComponent() for Swing.
public void paintComponent (Graphics g)
// Will erase the background!
super.paintComponent(g);
System.out.println("paint method of my thread..............");
g.setColor (Color.red);
g.fillOval (x_pos - radius, y_pos - radius, 2 * radius, 2 * radius);
}The more expert GUI developers could probably point you to the exact parts of the Java Tutorial that cover custom rendering and animation. But I could not be bothered googling them. -
Updating Transient objects in Kodo 2.5.5
I have a situation where I construct a JDO object in transient state in my
code ( for batch processing of data from a file into the database) by
calling the objects contructor and setting it's values. The row
representing this object may or may not exist in the database.
How do I make the object peristant ? If the row already exists, then I
must be able to update the row with the new values ( non-primary keys ).
If not, I should insert a new row.
There are no multi table relationships involved in this case. A JDO object
represents just one table.
We want to avoid the scheme which involves retrieve the object first and
then trying to update in a transaction.
AdarshTransaction t = kpm.currentTransaction();
try {
MyObject o = new MyObject(...)
t.begin();
Object id = ((PersistenceCapable)o).jdoNewObjectIdInstance();
((PersistenceCapable)o).jdoCopyKeyFieldsToObjectId(id);
try{
System.out.println(id);
Object trio = pm.getObjectById(id,true);
pm.deletePersistent(trio);
}catch(ObjectNotFoundException oe){
System.out.println("First time!");
pm.makePersistent(o);
t.commit();
}catch(...){ -
Hi everybody,
I have the next trouble, I need to clone an Object, but the method "clone()" in the Object class is protected.
I am working with a DBMSOO that provide me the following classes: Database, Transaction. I want to have a generic command that retrieve Objects from a database Object-Oriented, and then to make a cast to a specific class.
This is the code:
public class Lookup
private Object object;
public Lookup
Database db = new Database();
db.open( "dbUrl->server", Database.OPEN_READ_ONLY );
Transaction txn = new Transaction( db );
txn.begin();
object = db.lookup( "idObject" );
txn.commit();
db.close();
public Object getObject() {
return object;
My trouble is that when the Transaction is finished with commit() method, the object reference is null. I thought to clone the Object, but is not posible.
Could anyone help me, please?
Sincerely,
Alvaro
PS: Sorry, for my english. I know it isn't very good.Hi DrClap,
I understand you, but if I don't write the sentence:
txn.commit()
that close the Transaction, the reference "object" isn't null.
What's the matter?
Thanks a lot for your interesting.

Most mpd.class.php's are old and produce a lot of errors which caused me much frustration in this thread.
I was wrapping my head around why phpmpreloaded worked and the others never and it's because it uses an updated mpd.class.php. To save others the frustration and hassle I figured I'd post the new class here.
Enjoy.

Hyperion Planning business rules migrating to Calc Manager issue
It was suggested I post this in calc manager as well, so I hope cross posting is allowed!
We are trying to migrate from Hyperion Planning 11.1.1.3 to 11.1.2.2
Our business rules were migrated to Calc Manager by our IT team. The rules run (for the most part).
Our main complaint about this migration is that it excluded our comments inside the business rules and added it's own!
When we first open the rule it is in graphical mode. But on the Script Tab I can see our orignal Business rule, but it's missing comments. Not all comments -- those at the top of the rule are intact, but after it starts getting into the meat of the rule, it loses many, but not all of the comments. When I chose to edit this rule in script mode, then calc manager adds tons if its own comments, making the code very junky to read.
So, multiple questions -- how do we get the migration of business rules to calc manager to stop losing our important comments. Is it possible to get the newly migrated rules to initially open in script mode rather than graphical mode so that it doesn't add it's own comments. Or is there a way to turn off the added commenting?
This is a snippet of our rule in 11.1.1.3:
FIX ("D0P000 Pushdown")
"Accrued Salaries and Wages Pushdown" = "BTL Accrued Sal & Wages Total"->"WBS_I19990_PLAN" * (D0P000->"Total Reg Labor" / "LMSS (LRP TEMPLATE LEVEL)"->"Total Reg Labor");
ENDFIX
/* FIX on account members that should be rolled up in the AGG statement below. */
FIX (@DESCENDANTS( "Orders"),
This is what it looks like when it comes up in graphical mode in Calc Mgr 11.1.2.2 (note that comment is already missing):
FIX ("D0P000 Pushdown")
"Accrued Salaries and Wages Pushdown" = "BTL Accrued Sal & Wages Total"->"WBS_I19990_PLAN" * (D0P000->"Total Reg Labor" / "LMSS (LRP TEMPLATE LEVEL)"->"Total Reg Labor");
ENDFIX
FIX (@DESCENDANTS( "Orders"),
This is what it looks like when it switches from graphical to script (bonus comments are added):
FIX ( /*DIM:Entities*/"D0P000 Pushdown")
/*STARTCOMPONENT:FORMULA*/
"Accrued Salaries and Wages Pushdown" = "BTL Accrued Sal & Wages Total"->"WBS_I19990_PLAN" * (D0P000->"Total Reg Labor" / "LMSS (LRP TEMPLATE LEVEL)"->"Total Reg Labor");
/*ENDCOMPONENT*/ ENDFIX
FIX ( /*DIM:Accounts*/@DESCENDANTS( "Orders"),
Thanks for any help.
BrendaYou might learn to appreciate graphical mode in Calc Manager, we do. It is not like the old Business Rules in EAS. I am an old school calc script person, and have NO love for drag-and-drop coding ... I need control. ;-)
Insert a blank script object and paste your code into the 'Script' tab for that object. Set up your prompts and use the {} notation in your code. All of the comments will stay put ... as long as you DON'T USE EDIT, SCRIPT! We make a fair number of generic, reusable pieces of code and save them as shared scripts. These can be dragged into Rules. Click on the Rule's Begin object and choose the Script tab ... you will see how the bits are assembled into complete calc script. We've even come up with a way to use LOOP ... ENDLOOP as though it were a procedural IF statement so we can control whether or not a chunk of code is active or not.
Shared scripts are especially good for currency translation components since we occasionally add new currencies and want to make a change in one object that is used in dozens of business rules.

Very confused beginner here...
Hello everyone. I'm new to the board here. I am currently a junior meteorology major with a minor in computer science at Millersville University. To incorporate both my minor and major, I decided to make a computer program that scrolls weather watches and warnings across the bottom of a computer screen (much like they do on television). I am a beginner at Java, only using it for a few months. I really feel like I have bitten off more than I can chew with this program. However, I am dedicated in working through this problem. Below is a copy of the code I am using for this. I keep getting errors, however. I had it working perfectly, besides the fact that a) it never updated and b) it would never scroll more than one watch or warning, meaning it would just loop one over and over. I have also included the errors that I receive during this. Any help would be greatly appreciated. I am sorry if the code looks a bit trashy and disorganized. These are just some things, being a rookie, that I am going to have to learn how to clean up. Thanks

at java.awt.EventDispatchThread.run(Unknown Source)I don't know. There are classes your code requires (e.g., everything in the de.nava.informa packages) that I don't have, so I can't really compile or run your code.
I will say this: it's a confused mess. There's too much code and too little abstraction. This is typical of beginning object-oriented programmers.
When you start seeing LOTS of repeated stuff like this:
if (newscroll.contains("Tornado warning".toUpperCase()))
scrollLabel.setBackground(red);
}alarm bells should start ringing in your head. It appears that a Map with a String as key and Color as value is wanted. I can make all that code collapse into something MUCH smaller. If I externalize all those awful Color declarations into a File that's read on startup (e.g., taking in the key message and the RGB values and initializing the Map), now I have something that I can change more easily. AND there's less code to manage.
I see URLs, applet, TimerTask, HTML - the kitchen sink.
I can't tell you what this class is about.
Be lazier - write less code. That's what good programmers do.
Try to think more abstractly.

I wish to know if there are any refresh issues in the following scenario.
Consider the same application running in 2 distinct VM, jvm1 and jvm2 in a
simple
configuration without L2 cache.
In jvm1 I have:
PersistenceManager pm = pmf.getPersistenceManager();
pm.currentTransaction().begin();
Object oid = xxx;
Object o = pm.getObjectById(oid)
System.err.println(o.xxxx);
pm.currentTransaction().commit();
pm.close():
Then in jvm2:
PersistenceManager pm = pmf.getPersistenceManager();
pm.currentTransaction().begin();
Object oid = xxx;
Object o = pm.getObjectById(oid)
o.setSomeAttribute(xxxx);
pm.currentTransaction().commit();
pm.close():
Now if I execute in jvm1 the first code fragment, do I see the modification
applied in
jvm2 ?
Thanks in advance,
Guido Anzuoni.
BTW, are you going to include oid (and hopefully, class) keyword in
projection in kodo3 ?Guido,
Yes, you will see the modification in the next PM. The only "stale data"
issues you might see are when you get object ID X in JVM1, modify and
commit object ID X in JVM2, and then continue to reference it in JVM1
(without any closing or refreshing): you will continue to see the cached
version of object ID X.
When this situation is intolerable, you can use pessimistic
transactions: that will guarantee up-to-date views of the object, at the
cost of keeping database locks on the rows open.
In article <[email protected]>, Guido Anzuoni wrote:
No, no, just for confirmation. I have read some posts on this topic and I
have only shown my tipical usage.
Is this behaviour somehow dependent on optimistic settings ?
What if the DB schema is a preexisting one and there is no column for
optimistic locking check ?
Thanks again,
Guido.

Yes. Are you not seeing this behavior?
As for oid and class keywords, I'm not sure if the feature has been
resolved one way or another yet.

Can stream "capture process" skip an archivelog?
DB: 10.2.0.5, on Windows 2003 SP2 32-bits
A stream capture component in our database is stuck reading one the archive log file, and status in the v$streams_capture view is 'CREATING LCR' . It is not moving at all.
I think, the archivelog is corrupted and will guess skipping from reading the log can help??
Any idea?Find the transaction identifier in the trace file; for example in this trace the transaction is '0x000a.008.00019347'
Convert it from hex to decimal; in this example '0x000a.008.00019347' will be '10.8.103239'.
Example of trace file:

Then stop the capture process and execute the following procedure:
exec dbms_capture_adm.set_parameter('your_capture_process_name','_ignore_transaction','your_transaction_id_in_decimal_notation');
Now you can restart the capture process and it will ignore the tx. -
Importing mappings using OMBPLUS
we just started using OWB, and in our environment we do not want to migrate mappings from DEV to TEST to PRODUCTION using GUI. i heard that importing and deploying can be done using OMB scripting ..
can any please give some example scripts for importing mapping and deploying mappings on to a different box.
ThanksDo you need to move the mapping definitions over to each box? Or just deploy them to different boxes?
If you want a single design repository where you deploy from to multiple runtime areas, then this is acheived through creating multiple configurations and changing your project configuration prior to each deployment.
If, on the other hand, you want to MOVE the current mapping definitions to each box where you will, in effect, be setting up a new design AND runtime repository, then there is added complexity.
For example, scripting dropping old mappings prior to importing the new version of the project to avoid legacy objects hanging around becomes a potential issue. for that, you would need to script deployemnt plans of type DELETE for objects no longer wanted. This also helps script the new deployment as you don't have to code which mappings are being CREATEd, and which are being REPLACEd.
I have an OMB+ script I am just testing right now to load a project MDL file and deploy it to a new repository. I have a partial script for unloading and old version of the project, but it is not ready yet. This one also assumes a clean install where I even have to go so far as to register my runtime user, and define and register all schemas to be used by the control center. We also do not deploy normal database objects via OWB. This script assumes that the proper database setup for tables, sequences, views, etc. has been done prior to deploying the OWB mappings and process flows. We use Designer as the repository of record for all non-OWB database objects.
I don't claim to be an experienced TCL or OMB+ developer, but it might help you out as a starting point. Note that the config file and file of library functions used by this script (such as the exec_omb you will see that I use) are also appended to this post.

I'm half way through writing a web interface for mpd. I needed a way to interact with it so I searched around and found this. It's a php class that interfaces with mpd.
I downloaded it and it comes with an example php file for using it. The only problem is that when I use the example page it just prints out anything after the arrow operator. As far as I'm aware the arrow operator is for accessing class methods and variables but I've never actually done any OOP with PHP.
Anyway here is the example file:
<?

* Copyright (C) 2003-2004 Benjamin Carlisle ([email protected])
* http://mpd.24oz.com/ | http://www.musicpd.org/
* This program illustrates the basic commands and usage of the MPD class.
* *** PLEASE NOTE *** My intention in including this file is not to provide you with an
