Xmltype.toObject() creates partly empty object

xmltype.toObject() creates an object of the type created when registering the XML schema but in this object all text-elements are empty.
I registered an XML Schema in XDB 9i release 2.
When I create an instance of xmltype using CreateSchemabasedXML, toObjects creates an object in which all varchar "members" are empty. members which consist of furter object-types are not null, but within these objects the varchar members again are empty.
Is toObject() only partially implemented?

Seems you encountered the bug described in
Bug 3578226 - ORA-22814 when using XMLtype.toObject with empty XML elements.
The workaround mentioned there states to »store empty elements like <TEST/>«. Try if that helps.

Empty Object Array

Hi,
How can I create an empty object array in Java?
Thanks

Object object[] = new Object[len]; //len is an
Integer-value for the length of the arrayThat's right..

Partial XMLType toObject

Hi,
I have an XML schema registered with Oracle. The schema is annotated and during registration the PL/SQL types are created. I can validate an XMLType with this schema, as well as use toObject to populate an object with data from the XMLType. The XML looks like this:
<root>
<complexObject>...... very complex object with many elements, sub-elements and sequences .......</complexObject>
<complexObject>...... very complex object with many elements, sub-elements and sequences .......</complexObject>
<complexObject>...... very complex object with many elements, sub-elements and sequences .......</complexObject>
<complexObject>...... very complex object with many elements, sub-elements and sequences .......</complexObject>
<complexObject>...... very complex object with many elements, sub-elements and sequences .......</complexObject>
</root>
There can be a lot of "complexObject" elements in the sequence and the XML can be huge.
The <root> element has the corresponding T_ROOT type, the <complexObject> elements had the corresponding T_COMPLEXOBJECT type. T_ROOT has a VARRAY of T_COMPLEXOBJECT.
So, like I said before, I can populate an object of type T_ROOT from the XML without an issue using toObject on the XMLType. However, due to the complexity and size of the XML, I want to split the big XML into multiple T_COMPLEXOBJECT objects. I can do this using XPath extract in a query, returning me one XMLType row per "complexObject". Here is where I'm stuck: I want to use a cursor on the above query and process each "complexObject" one by one. For this, I need to somehow be able to do something similar with toObject, but on the "complexObject" XMLType fragment only to populate an object of type T_COMPLEXOBJECT, not on the whole T_ROOT.
If I do:
l_xml.toObject(l_obj, 'myschema.xsd', 'complexObject');
instead of
l_xml.toObject(l_obj_root, 'myschema.xsd', 'root');
I get:
ORA-31043: Element 'complexObject' not globally defined in schema 'myschema.xsd'
ORA-06512: at "SYS.XMLTYPE", line 196
ORA-06512: at line 38
Thanks!

Best Practice question - null or empty object?

Given a collection of objects where each object in the collection is an aggregation, is it better to leave references in the object as null or to instantiate an empty object? Now I'll clarify this a bit more.....
I have an object, MyCollection, that extends Collection and implements Serializable(work requirement). MyCollection is sent as a return from an EJB search method. The search method looks up data in a database and creates MyItem objects for each row in the database. If there are 10 rows, MyCollection would contain 10 MyItem objects (references, of course).
MyItem has three attributes:
public class MyItem implements Serializable {
    String name;
    String description;
    MyItemDetail detail;
}When creating MyItem, let's say that this item didn't have any details so there is no reason to create MyitemDetail. Is it better to leave detail as a null reference or should a MyItemdetail object be created? I know this sounds like a specific app requirement, but I'm looking for a best practice - what most people do in this case. There are reasons for both approaches. Obviously, a bunch of empty objects going over RMI is a strain on resources whereas a bunch of null references is not. But on the receiving end, you have to account for the MyItemDetail reference to be null or not - is this a hassle or not?
I looked for this at [url http://www.javapractices.com]Java Practices but found nothing.

I know this sounds like a specific apprequirement,
, but I'm looking for a best practice - what most
people do in this case. It depends but in general I use null.Stupid.Thanks for that insightful comment.

I do a lot of database work though. And for that
null means something specific.Sure, return null if you have a context where null
means something. Like for example that you got no
result at all. But as I said before its's best to
keep the nulls at the perimeter of your design. Don't
let nulls slip through.As I said, I do a lot of database work. And it does mean something specific. Thus (in conclusion) that means that, in "general", I use null most of the time.
Exactly what part of that didn't you follow?
And exactly what sort of value do you use for a Date when it is undefined? What non-null value do you use such that your users do not have to write exactly the same code that they would to check for null anyways?

XMLType.ToObject()

Hi there,
I am running into a problem when (in Oracle9i Enterprise Edition Release 9.2.0.6.0) trying to map an XML document contained in an XMLType variable to a corresponding object-type variable using the XMLType.ToObject() function.
The problem occurs when the XML contains "repeating" fragments.
I do not know how to define the corresponding object-type in such a way that XMLType.ToObject() does not run into error "ORA-19031: XML element or attribute ... does not match any in type ...".
For example the following XML:
====================
<MyObject>
<ELEMENT01>VALUE01</ELEMENT01>
<ELEMENT02>VALUE02</ELEMENT02>
<MYGROUP>
<GROUPELEMENT01>VALUEG01E01</GROUPELEMENT01>
<GROUPELEMENT02>VALUEG01E02</GROUPELEMENT02>
</MYGROUP>
<MYGROUP>
<GROUPELEMENT01>VALUEG02E01</GROUPELEMENT01>
<GROUPELEMENT02>VALUEG02E02</GROUPELEMENT02>
</MYGROUP>
</MyObject>
====================
The corresponding object-type that I defined is as follows:
====================
create or replace type TP_MYGROUP_REC as object
(GROUPELEMENT01 varchar2(50)
,GROUPELEMENT02 varchar2(50)
create or replace type TP_MYGROUP_TAB as table of TP_MYGROUP_REC;
create or replace type TP_MYOBJECT as object
(ELEMENT01 varchar2(50)
,ELEMENT02 varchar2(50)
,MYGROUP TP_MYGROUP_TAB
====================
I tested with the following script:
====================
declare
l_xmltype xmltype;
l_myobject TP_MYOBJECT;
begin
l_xmltype := XMLTYPE
('<MyObject>
<ELEMENT01>VALUE01</ELEMENT01>
<ELEMENT02>VALUE02</ELEMENT02>
<MYGROUP>
<GROUPELEMENT01>VALUEG01E01</GROUPELEMENT01>
<GROUPELEMENT02>VALUEG01E02</GROUPELEMENT02>
</MYGROUP>
<MYGROUP>
<GROUPELEMENT01>VALUEG02E01</GROUPELEMENT01>
<GROUPELEMENT02>VALUEG02E02</GROUPELEMENT02>
</MYGROUP>
</MyObject>');
l_xmltype.ToObject(l_myobject);
end;
====================
This results in: ORA-19031: XML element or attribute GROUPELEMENT01 does not match any in type TP_MYGROUP_REC.
Does anyone out there know how to define the object-type(s) in such a way that I can cast this type of XML to an object using XMLType.ToObject() ?
Thanks a lot for your reaction,
Jaap Kool

In absence of an XML schema, Oracle uses a canonical mapping between SQL objects and XML.
For instance, the XML structure corresponding to the object hierarchy defined in the first post is :
<TP_MYOBJECT>
<ELEMENT01>VALUE01</ELEMENT01>
<ELEMENT02>VALUE02</ELEMENT02>
<MYGROUP>
    <TP_MYGROUP_REC>
      <GROUPELEMENT01>VALUEG01E01</GROUPELEMENT01>
      <GROUPELEMENT02>VALUEG01E02</GROUPELEMENT02>
    </TP_MYGROUP_REC>
    <TP_MYGROUP_REC>
      <GROUPELEMENT01>VALUEG02E01</GROUPELEMENT01>
      <GROUPELEMENT02>VALUEG02E02</GROUPELEMENT02>
    </TP_MYGROUP_REC>

What is the advantage of using IB to create XIBs/Class Objects over coding?

Hi all,
I hoping someone can provide me some pros and cons as to when I should use IB to create XIBs and/or class objects as opposed to directly coding them.
For example, if I choose Apple's Template for creating a Navigation Based Application (cocoa touch), the project creates two NIB files - MainMenu and RootViewController.
However looking at one of demo apps SimpleDrillDown, it does not have a RootViewController XIB and instead creates it via code.
Another example from the same two apps is that the template generates a "Navigation Controller" class object in the Mainmenu.xib. SimpleDrillDown does not bother with this in the XIB, but uses code to generate the controller:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Create the navigation and view controllers
RootViewController *rootViewController = [[RootViewController alloc] init];
UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController];
self.navigationController = aNavigationController;
[aNavigationController release];
[rootViewController release];
// Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
as opposed to the template which only needs this:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Configure and show the window
// Navigation Controller is defined in MainWindow.xib
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];
So what are the advantages of each approach. Why does apple suggest one approach and yet all its demos use another.
Any thoughts, answers gratefully received.
TIA, Michael.

You can do whatever you're comfortable with, but most of the best Cocoa programmers--the ones on the Mac, I mean--recommend putting everything you can into Interface Builder.
It's a little like the difference between writing a program to do a bunch of financial calculations and using a spreadsheet. Yeah, the program can do everything the spreadsheet can--and more besides--but you'll find it far easier to create, use and modify the spreadsheet.
Interface Builder takes away a lot of completely meaningless choices ("What order should I create the objects in? How should I name the variables? How should I create their frames? What order should I set the attributes in?"), leaving you with an interface optimized for creating and arranging objects, and allowing your code to focus on what you really do need to think about--your application's logic.
(By the way--part of the reason Apple's demos don't all use Interface Builder is that the very first SDK releases didn't have it. Back then, you had to create all your views programatically. Believe me, I have no wish to go back to setting autoresize masks manually. Now get off my lawn, whippersnapper.)

Can I create a DIMENSION object mappign without a Dimension table?

I understand how I can create a dimension object and it's associated table. However, can I map my enterprise data directly to the dimension object itself and skip the loading of the dimension table? The enterprise data for most of my reporting warehouse for the greater part is fairly simple and requires only joins to some reference data.

Matthew,
Like you stated, the dimension object in OWB will generate scripts for two object types. The first is a dimension object and the second is a table. In the dimension object the hierarchical structure(s) (meta data) is stored and the table stores the data. So you always have to load your enterprise data into the table.
Hope this helps.
With kind regards,
Bas Roelands

How to create an Empty Playlist File on Mac?

Hello everyone, I'm working on a Music Player script, I was able to play a file via the default player as when we doubleclick on a file. The problem is I have no control over the Player, so to "stop" a file I could play a "silent" mp3, one with 1 second of silence in it for example. I discarded the idea since I had to distribute this silent.mp3 file along with the script. A better option is to play a "playlist", since playlist files are text only, I could create them an empty playlist file on the fly...
so, the question is, what's the default playlist extension on a mac? and how to create one on the Mac?
in windows the default player is Windows Media Player, the default playlist file extension is *.wpl.
here's the contents of an empty playlist
<?wpl version="1.0"?>
<smil>
    <head>
        <meta name="Generator" content="Microsoft Windows Media Player -- 12.0.7601.18150"/>
        <meta name="ItemCount" content="0"/>
        <title>empyPlaylist</title>
    </head>
</smil>
here's the script, so far Windows only, at least to stop the file being played.
// script.name = musicPlayer_Windows.jsx;
// script.needs = I need to create an Empty Playlist File for the Mac, that will play on the default music player when executed
// carlos canto, 10/12/2014
var w = new Window('dialog', 'Music Player');
var btnFile = w.add('button', undefined, 'Select an *.mp3 file to play...');
var lblSong = w.add('edittext', undefined, '');
lblSong.characters = 30;
var btnPlay = w.add('button', undefined, 'Play');
var btnStop = w.add('button', undefined, 'Stop');
var btnClose = w.add('button', undefined, 'Close');
btnPlay.enabled = btnStop.enabled = false;
var emptyPlaylist = getEmptyPlaylist ();
btnFile.onClick = function () {
    var file = File.openDialog ("Select File to Play...", '*.mp3', false);
    lblSong.text = file.displayName;
    lblSong.file = file;
    btnPlay.enabled = btnStop.enabled = true;
btnPlay.onClick = function () {
    lblSong.file.execute();
    $.sleep (300);
    BridgeTalk.bringToFront('estoolkit');
btnStop.onClick = function () {
    emptyPlaylist.execute();
    $.sleep (300);
    BridgeTalk.bringToFront('estoolkit');
btnClose.onClick = function () {
    w.close();
w.show();
// this function creates an Empty Playlist file (Windows) on the fly, this file will be used to "stop" a playing file
// I need a similar function for Mac
function getEmptyPlaylist () {
    var desk = Folder.desktop;
    var f = new File(desk+'/emptyPlaylist.wpl');
    if (!f.exists) {
        var s_emptyPlaylist = (new String("<?wpl version=\"1.0\"?>\n<smil>\n    <head>\n        <meta name=\"Generator\" content=\"Microsoft Windows Media Player -- 12.0.7601.18150\"/>\n        <meta name=\"ItemCount\" content=\"0\"/>\n        <title>empyPlaylist</title>\n    </head>\n</smil>\n"));
        f.encoding = 'utf-8';
        f.open('w');
        f.write(eval(s_emptyPlaylist));
        f.close();
    return f;
thanks in advance
Carlos

hmm...I think it's going to be more complicated than I thought.
correct, this script targets the ESTK, it is part of a larger Illustrator script, which doesn't have doScript either...I would go with applescript as last resort. I think going with the playlist file is easier.
based on your comment I realized users might change their default players, so on Windows I'm going to change the playlist file from *.wpl to the more universal *.m3u, I guess whatever decent player made the default, supports this file.
so, will an *.m3u playlist file play on the default mac player (itunes) when executed?
File("~/Music/iTunes/iTunes Media/Music/emptyPlaylist.m3u").execute(); // will this play on itunes?
I noticed that the *.m3u file can be blank, it will still "play" when executed() and effectively "stops" any music file currently being played...if this happens on Mac also, that's what I'm after.
thanks for helping Dirk.

Creating Multiple Resource Objects for OOTB Connectors

All,
I am trying to create a second AD User resource object for the OOTB connector. I would like to think that the AD Connector (and all connectors, for that matter) was designed to handle the creation of multiple Resource Objects for the same Resource Types, but am I wrong? It doesn't seem like the OIM Connector can handle this easily.
Has anyone created multiple resource objects for a connector? Is this a fairly simple task, or will it require a large effort? Is it even possible? Any pointers?
Thanks!

I will provide a little help with the duplication. I found the best way to do it is to import the original connector. Go through the different pieces making each one have a unique name, that is not part of any of the other piece names. You need to have unique names for the following:
1. Resource Object
2. Process Definition - Provisioning
3. IT Resource
4. Form - Process
5. Scheduled Task
After you import the connector, rename each of the following to something unique. I would also update your process form to have a default value of your IT Resource, as well as your scheduled task values to point to the new unique names. Export the 5 items, no dependecies. The adapters will all be the same. Use find and replace for the values and then import the new XML. If it works, duplicate the XML for each of the new workflows you want to create.

How to create a new object of HttpServletRequest class manually?

Dear all,
I don't know how silly my question is, however I have no way except asking.
I know that when I send a request from the client to the server, server authomatically creates an object of
HttpServletRequest and assigns all the request information to that object, so that you can extract these information by the available methods in the HttpServletRequest class like getHeader, getMethod and so on. What I need to do in my project is doing all above process manually. My question is how I can do it?
In other words, I have the header and body part of a http request and I want to create a HttpServletRequest
object and assign the header and body data to the object so that I'll be able to extract those data by using the getHeader, getMethod and other methods available in the HttpServletRequest class.
Please Help me, I really need your help?
Your help is appreciated.
Thanks.

Hi shadgar ,
as rightly mentioned by Sudha and GrayMan, you can provide the implementation for the HttpServletRequest interface in your own way for the requirement, but it leads to a new Servlet Container development as you need to handle many things than the HttpServletRequest.
I think the current interface and the Servlet Container will be able to handle if your request is over HTTP protocol and it don't deviate from the prtocol's request/response model.
Check out the javax.servlet.http.HttpServletRequestWrapper class, which is the implementation of the javax.servlet.http.HttpServletRequest and javax.servlet.ServletRequest interfaces.
Hope it will give some idea about the actual problem and rethink about the solution proposed.
Thanks,
Sanath Kumar

Alternative to XMLTYPE.TOOBJECT to populate a UDT

Is there any alternative option that can be utilized other than the XMLTYPE.TOOBJECT to populate an oracle object via a clob or raw or XML string?

Maybe something like this?:
SQL> DECLARE
   l_xml   XMLTYPE
      := XMLTYPE
           ('<?xml version="1.0"?><root><itm>A</itm><itm>B</itm><itm>C</itm><itm>D</itm></root>'
   TYPE t_num IS TABLE OF VARCHAR2 (50)
      INDEX BY BINARY_INTEGER;
   v_val   t_num;
BEGIN
   FOR c IN (SELECT ROWNUM, EXTRACTVALUE (COLUMN_VALUE, 'itm/text()') itm
               FROM TABLE (XMLSEQUENCE (EXTRACT (l_xml, '/root/itm'))))
   LOOP
      v_val (c.ROWNUM) := c.itm;
   END LOOP;
   FOR i IN 1 .. v_val.COUNT
   LOOP

After installing iphoto 9.5 some of my projects are completely or partly empty after regenerating, how can I get them back?

After installing iphoto 9.5 some of my projects (photobooks) are completely or partly empty after regenerating, how can I get them back?

Define "everything" because if you've tried everything then your last recourse is:
1 - restore your backup copy of your iPhoto Library created just prior to your Yosemite upgrade or
2 - Starting over from scratch with new library
Start over with a new library and import the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from your original library as follows:
1. Open the library package like this.
2. Launch iPhoto with the Option key held down and, when asked, select the option to create a new library.
3. Drag the subfolders of the Originals (iPhoto 09 and earlier) or the Masters (iPhoto 11) folder from the open iPhoto Library package into the open iPhoto window a few at a time.
This will create a new library with the same Events (but not necessarily the same Event names) as the original library but will not keep the metadata, albums, books slideshows and other projects.
Note: your current library will be left untouched for further attempts at a fix if so desired.

Creating z archive objects???

Hello gurus,
in one of my assignment we need to archive z tables.. its understood that we need to create z archive objects for them..we have differenct types of tables.. input, output and masterdata tables...
1. can i create a single archive object for these tables.
2. can i create a separate objects for input , output and master data tables
<<removed>>

Hello my friend I have the same situation in my case I have a tutorial of sap which I have read and I recomend you that you need to read in order to under stand archiving.
in this tutorial there are some parts in which you can see some pages where it mentions some sample of writing, delete, reading archiving progrma that there are in SAP system.
Check this link and I think it can help you.
In my case I do not understand all the code sample.

I also can confirm the same issue as with previous posters, tried all stuff found on the net that seems related to this issue.
Nothing so far as solved it for me, I also had to downgrade to 4.2.18. Not optimal but atleasat i can work until this has been sorted out.

Create an empty midi region

Hey, from the manual:
Π Tip: If you want to insert one chord per bar into a very busy part, it’s much faster to
create an empty MIDI region, and enter the desired chords into it (the cursor moves to
the next bar when you press Tab in empty regions). Following chord entry, you can
either merge the MIDI region with the original MIDI region in the Arrange area, or copy
and paste all chords at once.
I'm trying to create a few lead sheets that will display chord symbols, and ideally the melody as well. Sounds like it's easier to write in the chord symbols manually using the chord tool from the text box, but how do I create an empty midi region as stated above? The score editor will only open if there is information in a region somewhere. I could play one note I guess...but how's this empty thing work? Also, would you recommend using lead sheet from staff styles in the layout menu? Most jazz charts use a piano staff, melody up top, chord changes in the bottom. Perhaps I need to work backwards and set up the staff styles first, then record into them?
