Generating Data Object Classes

Is JDeveloper able to generate object classes from a database table? Example I have a table called car that has color and brand for columns. Can JDeveloper generate the class called CarDO that has the getters and setters for the table called car? If so please help I have several large tables to convert to objects.
Thanks!

I recommend you take a look at the JOB extension: http://otn.oracle.com/products/jdev/htdocs/partners/addins/exchange/job/content.html

Error while generating Data Objects in sdoe_wb SAP for Basis component

Dear all,
While generating SAP BASIS Components getting error
After installations of SAP Netweaver Mobile 7.1 SP11 and all the Notes applied for SP11 i have done the Generation for all the SAP BASIS Data Objects
All the Data objects are generated except AGENT_CONFIG, ARCHIVE
When i check the same in smq2 it shows the error in Function module SDOE_GENERATE_MBO for the user FUNC001,in status text it shows "connection closed (no data)"
kindly help on this issue.
Regards
Revanth

Hi,
well, I guess if you mean you did reset the queue - you deleted all emtries with error. Try to avoid this in the future - you will get unwanted side effects by that. There are only a few errors that make this behaviour necessary.
Usually you should select the entry on the first screen - so you see the status of the queue on the second one. On there you can select the queue and while pressing the green tick, you can restart it. If it is a timeout - this restart usually helps.
Wondering why you have an issue with basis objects - did you run through the complete setup guide up to this point?
Regard,
Oliver

Using predefined data objects classes.

I am always trying to be a better, more efficient Flex developer and I was looking at a project by Christophe Coenraets where he created collaberative forms using Flex/BlazeDS. I saw in his application that he was using multidirectional binding to a Class Object for each form in the application. For example, this is the MortgageApplication.as
package
    import mx.collections.ArrayCollection;
    [Bindable]
    public class MortgageApplication
        public var firstName:String;
        public var lastName:String;
        public var ssn:String;
        public var phone:String;
        public var mobilePhone:String;
        public var email:String;
        public var notify:Boolean;
        public var usCitizen:Boolean;
        public var address:String
        public var city:String
        public var state:String
        public var zip:String
        public var singleFamily:Boolean;
        public var salePrice:Number = 500000;
        public var downPayment:Number = 100000;
        public var closingDate:Date;
        public var jobList:ArrayCollection = new ArrayCollection();
I have an application that I use multiple forms to input information into the database and then I use Objects (actually ObjectProxys) and ArrayCollections to store information to display. I use the Mate Framework and have manager classes that store predefined bindable variables (empty) that are injected into the view as needed or requested. In the manager class I just create a new ObjectProxy (or ArrayCollection) and use the information passed in (an ArrayCollection from ColdFusion) and create/modify the ObjectProxy/ArrayCollection before having it injected.
Is it better practice or more efficent to predefine object classes (such as above from the example) then just populate them in the manager class before the injection or just create an new blank Object or ArrayCollection on the fly. Is there any difference?
Set up a seperate Class:
package
    [Bindable]
    public class Person
        public var firstName:String;
        public var lastName:String;
        public var phone:String;
and do this in the Manager:
public function setPerson():void {
     var person = new Person();
     person.firstName = "Steve";
     person.lastName = "Smith";
     person.phone = "555.555.1212";
OR just have this declaired in the Manager as
[Bindable] public var person:ObjectProxy;
public function setPerson():void {
     person = new ObjectProxy();
     person.firstName = "Steve";
     person.lastName = "Smith";
     person.phone = "555.555.1212";
Thanks to anyone who wants to help me become a better developer!

ObjectProxy access is significantly slower that data class access. ObjectProxy will not tell you if you mistype the name of a property and you can spend hours trying to find some place were you typed ssm insead of ssn.

Unfortunate Drawback in Flash Date Object

I dont understand for what particular reason there is no way
to create a Date Object that represents particular TimeZone other
then I am in.(it seems that it is done intentionally)
for example I would like to create a date Object that says 3
pm EST
and assuming that this code is run from 7 different
timezones,
so if user from PST timezone runs the code, new Date line
will generate date object with UTC offset set to PST, and its
readonly so cant be changed ... hhhmmm why ???
this is (hate to say) insane, how can you construct date and
give a different UTC offset other than timezone user executing the
code is in.

the silence is deafening on this issue.
1. flex doesn't allow the user to set the timezone, it is hard-coded to read the system setting
2. all flex date related controls (formatter, date picker, etc) are hard-code to use the non-UTC values
3. the Date class is marked final, preventing any type of work-around
4. The Date does not contain contain timezone/offset as was originally entered - it only has the relative offset based on the system timezone of the user who is currently looking at the date.
if any one of these four things was changed it would instantly allow us to deal with dates across timezones. it seems hard to believe that every one of these possible work-arounds was intentionally blocked by the flex team. is there some other solution, or is this just covering up some deficiency of the flex framework?
it's a a total buzz-kill if you have an app where people travel across timezones, or there are people in multiple timezones syncing. it's is pretty much impossible to show the correct dates easily - flex assumes you always want to display all dates in the local users's timezone.
what is the "correct" way to handle this - always store dates as two fields, one for the date, another for the timezone? then use UTC for everything..? and override all Flex date controls..? i don't get it, am i missing something?

Message class as result data object

hello brf+ users,
is it possible to use as Result data object in a Case expression a message from a custom message class?
thanks
danilo

thanks Carsten,
my requirement can be simplified in
IF FISCAL CODE
equals to " " then "001" ENTRY MISSING is returned
otherwise "000" check ok is returned.
where 000,001 are domain values of an element (MESSAGE RESULT).
can i use the message class as result? is there a way to anchor the result to the message class?
thanks
danilo

The creation of device local data objects - Unable to find generated object

Hi all,
I get an error when I try to generate an ESDMA containing a "Device Local" data object.
I have created a "Device Local" data object containing a very simple node structure. The object is "active" and everything seems to work fine, until I generate the ESDMA. The following error is shown : Unable to find generated objects in repository.
The esdma is generated without problems, when I remove the device local data object.
I hope you have some ideas of what the issue might be.
Best regards,
Nima

Hi Siva
Actually i am working on this problem together with Nima and the problem is not related to SAP Basis objects.
The problem is in SDOE_WB, with the SWCV. Creating a Data object of type LOCAL DEVICE and a NODE. If you add a field/s and then activate, and look in Generated objects The Table object is not generated (only the structure and the table type). At this point there are no syntax/error messages.
If we try to generate an esdma using the ESDMA design time, using this SWCV, it fails, with the message, Unable to find generated objects, in the repository. That is it is looking for the Table object that was not generated in sdoe_wb. This is only a problem with creating a data object of type DEVICE LOCAL, every other type of DO is fine.. I assume it is an SAP error.

EqualsBuilder for Class containing Date object

Hi,
Does EqualsBuilder work fine if my Class has a Date object? For example, my CreditCard class has creditCardExpDate of type Date.
My Junit failed even though the values for expected and actual look same
Expected
CreditCard@1394894[creditCardTypeCode=A,creditCardNumber=1234567891234567,creditCardExpDate=Sat Feb 28 00:00:00 EST 2009]

CreditCard@1b8f864[creditCardTypeCode=A,creditCardNumber=1234567891234567,creditCardExpDate=Sat Feb 28 00:00:00 EST 2009]
Any help is appreciated.

EqualsBuilder from commons-lang? Wow that method is special.
It's just impl equals yourself.

Generate Data model from Class model

I am using JDeveloper uml features for a first time, so I am interested if there is a option that I can generate class model to the data model.
If I have class model and than when right-click select Generate , there is a option to generate data model from it.
But it is dimmed. Is there any precondition to achieve before this option become possible.
Thanks in advance .

The link you mentioned has the Prerequisites,
Do include all the jar in you path.

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object

Object Class Invalid when downloading the pricing procedure from ECC to CRM

Hi,
I want to download the pricing procedure for that I have created the ZDNL_CUST_CND which contains only the following tablesT683, T683S, T683T and T683U.
When I check in R3AM1 status is Red.
The following Error have been found in SLG1
     Object class invalid
     Error in inbound data check
Message no. CND_MAP120
Diagnosis
During the receiving inspection, serious errors were found in the consistency of the exchange object.
System Response
Data exchange is terminated
     Data exchange terminated
Message no. CND_MAP122
Diagnosis
Data exchange has been terminated due to serious errors. No exchanged data has been posted in the system.
The following Error has been found in SMQ1
     R3AD_CONDITIONS     STOP
Details of STOP
Set by Host name: litldq; Transaction: ; Report: SAPMSSY1
I have checked the connection, everything is perfect.
What may be the problem?
Thanks

Hi,
Please try to re-generate the adapter object (ZDNL_CUST_CND) services using trx.
SMOGGEN
. After this, try re-running the load.
I assume that your CRM inbound mapping module are correctly coded. If the problem persists, try de-registering the R3AD_CONDITIONS inbound queue using trx.
SMQR
and then debugging the inbound queue from the same trx. after re-starting the load.
Reward if this helps!

Data Types
Data types are templates for creating data objects. Data types can be defined independently in the ABAP program or in the ABAP Dictionary. As attributes of a data object, data types can also exist in a non-independent state. Data types do not use any memory space for work data, but may require memory for administration information.
As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types.

Data Objects
A data object is an instance of a data type and occupies as much memory space as its type specifies. An ABAP program only works with data that is available as content of data objects. Data objects are either created implicitly as named data objects, or exanonymous data objects using CREATEDATA.
Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.

EventListener function specific to generated display object container

This has to be simple, if only I knew how. I'm an AS3 newbie,
and am having difficulty setting up multiple specific
EventListeners within a code generated display object container.
I am generating a 'page' (Sprite) with a heap of 'cards'
(Sprites) on it. Each of those cards, in turn, contains a selection
of text boxes and other objects generated from database output
using a 'for' loop.
My hope is to attach an EventListener to each 'card' so that
a MouseEvent will let me manipulate the data that lead to the
content of that actual card (the i-th iteration of my for loop).
I've been playing with everything I can think of (limited
repertoire of thoughts though) and the best I've managed is for my
EventListener to access the final set of data, whichever 'card' I
click on.
I've summarised and attached my code for the function, and
would appreciate any advice (however basic) on how to get back to
the i-set of data from the EventListener attached to the i-th card.
I can handle the PHP and MySQL side of things but am fumbling my
way into the OOP of AS3.
Cheers
Dougal

Another way would be to extend Sprite and add an id value.
Something like:
package{
import flash.display.Sprite;
public class MySprite extends Sprite {
private var _id:int;
public function MySprite(id:int){ _id = id; }
public function get id():int { return _id; }
And then in your code you'd just make instance of MySprite,
passing it i:
// build the cards and text boxes and add them to the
reviewPage
for (var i:int = 1; i < (cardsRequired+1); i++) {
// setup the locations for all the objects
var displayCard:Sprite = new MySprite(i);
You can then get i in the event listener function by using
the id getter:
function accessThisData(e:MouseEvent):void{
trace(e.target.parent.id);

Are there any shortcuts for creating Value Object Classes?

Hi,
I'm using a Remote Object to connect to my server
(pyAMF/Django). I'm getting stuck with the creation of Value Object
Classes. It doesn't seem very DRY to have a class on my server
representing the data model and then have to recreate that class
and all its properties in my Flex app.
Are there any shortcuts for creating client side VOs from
server side data?
I was thinking about declaring an empty VO class in Flex, and
then dynamically assigning/casting my Proxy object to that class.
It seems like that approach may cause problems for the Flex
compiler though.
Any hints?
Thanks!

One thing that has helped me in that area is a free tool from
Farata Systems called
DTO2Fx. If you're using Java and Eclipse, it's a great time saver.
You simply install a (very lightweight) Eclipse plugin, add a
single annotation to your Java VO classes, and it automatically
generates your Flex VOs. It even creates a base and extended
version of each VO on the AS3 side so you can add code to the
extended VO without fear of having your changes overwritten when it
regenerates your Flex VOs.
