Regarding OBJECT class. A question please.

A question regarding the Object class.
Please correct me in case I am wrong.
If I create a class called Foo :
class Foo{
Foo(){
}The constructor of class Foo automatically invokes the constructor
of its super class.ie it is like saying :
class Foo{
Foo(){
super();
}Am I Right?
Even if the Foo class constructor does not include a call to 'super',
it is implicitly invoked.
That is the reason the Foo class can invoke/send messages toe methods defined by 'Object',
as 'super' defined on Foo's constructor constructs/instantiates 'Object'
Am I Right again ?
Now,I have just noticed that the Object class does not contain any constructor
So how can the constructor of Foo call super implicitly if the Object class
does not contain any constructor.

So how can the constructor of Foo call superimplicitly if the Object class
does not contain any constructor.Even if you don't specify one, there will alwaysbe
at least a no-args c'tor.But if you do specify a ctor with args, the
compiler will not insert a no-arg ctor for you.That why I said there is "at least" a no-args (or more args) c'tor [in any class].

Issue regarding object class RKAUFTRAG,

Hi friends,
My issue is regarding object class RKAUFTRAG,
while passing this object class to function module 'CHANGEDOCUMENT_READ' it is extracting records only for changes, but i want both for creation and deletion too. this function module is working fine for other object classes like for ANLA and ALLOCATION.
My requirement is whatever created(KO01) or changes(KO02) made for internal order master data. sh. come throgh object class RKAUFTRAG, but except changes i am not getting for creation and deletion.
creation is reflecting in object class ANLA.
in SWEC and SWED, this object class is configured for all.

ToString() of the Object class. Guide please

Hiya,
I need to ask a question please.
I havent understood the exact meaning of the toString() defined
in the Object class?
When and where do we need to override this?
How can I use this inherited method and see the output
How can I use this method,now overidden and see the output.
Can some please send in a small code...

Object Class -Thread

Hai Respected Friend ,
I have one doubt regarding Object Class. for what purpose the Object class has some methods like Notify(),Notify All(),wait() though we are not using those methods except with Thread class.
why they are defined these methods in the Object Class ,why not in the Thread Class even though it is only useful with Thread Class.
Please give clear ans.
Thanks

Actually, though these methods are useful only in a multi-threaded environment, no Thread objects are directly involved. What you need to specify isn't a thread object (the current thread is always the one affected) but the monitor, which can be any kind of Object.I would have been happy if they had defined a Lock class with wait and notify methods, because I prefer doing:
public class C {
private final Object lock = new Lock();
public void method() {
synchronized(lock) {...}
}to
public class C {
public synchronized void method() {
}In the second case, you have to contend with other code incorrectly calling wait/notify on an instance of C.
So I don't see the win in these being java.lang.Object methods, other than allowing you to create one less object -- what an efficiency win ;-)However, there are times when it makes sense to expose the lock. For instance Collections.synchronizedXxx.

Where is the getString() implementation for RS and Object class question

Dear all,
I had these two questions ringing since a long time.
1)ResultSet is an interface.
In my jdbc code I have generally written rs.getString() and rs.getInt etc.. without giving a second thought as to where exactly is this getter implemented !
I have RTF API .. without too much help.
Could some one kindly explain Where is the implementation of the getString method ?
2) Could you please tell why the Wait() Notify() and NotifyAll methods have been implemented in the Object class ? What was the need to define em in the Object class ?
Thanks in advance for your time spent on this.

A desire to not have to couple your code to a particular database and JDBC driver. It's a classic example of the abstract factory pattern

Object class deployment - Basic form question

OK, I subclass calendar object from Oracle provided standard
object class. What do I need to deploy to use this form now
apart from calendar.pll and my fmx. What about the object class
from which I sub-class. Do I need to compile and deploy that
also? How will form resolve this on run time the parent object
class as I really did not copy, just sub class and we do not
deploy original class? Basic form question. Thanks.

You can set the "help" property on the field (which gives you the little "information" icon link beside the field).
You could also try adding another field of another class above or below:
<Display class='InlineAlert'/>
<Display class='ErrorMessage'/>
<Display class='HtmlPage'/>
..etc

LDAP BC QUESTION ABOUT OBJECT CLASSES

Hi
i am working with a bpel and its ldap-bc, when i create an entry in my ldap through the bpel it has all the object classes from the attributes i set. for example if i set cn and sn attributes then my entry has the object class person; i want to know if there is any way of setting object classes to my entry on the ldap, even if i am not setting any attributes; for example if i only set the cn and sn attributes using the bpel, i still can tell the entry that it can has another objectclass like iplanet-am-user-service with out setting any of its attributes.
thanks for your help

Actually, I'm not getting duplicate objects, but I like to get rid of
doubles in one particular column.
For example if I had a table as follows:
Table DESC
int pkid
String description
description can contain duplicate entries, I want to query as follows:
select distinct description from DESC
How could I write a query which retrieves all tuples in a table, but removes
duplicate from a specific column?
Thanks.

How does the engine use DISTINCT automatically?It detects whether joins are made such that duplicate rows might be

What I basically want to do is to remove any doubles I get from the

SELECT without the DISTINCT keyword.You shouldn't be getting doubles. If you are, could you please post the
offending JDOQL filter and give some description of the schema and/or

been resolved for our upcoming 2.5 release.
Is there also a way I can specify GROUP BY?No, JDOQL does not have an equivalent to GROUP BY.

A question about Object Class

I got a question about Object class in AS3 recently.
I typed some testing codes as following:
var cls:Class = Object;
var cst:* = Object.prototype.constructor;
trace( cls === cst); // true
so cls & cst are the same thing ( the Object ).
var obj:Object = new Object();
var cst2:* = obj.constructor.constructor;
var cst3:* = obj.constructor.constructor.c.constructor;
var cst5:* = Object.prototype.constructoronstructor;
var cst4:* = Object.prototype.constructor.constructor.constructor;
var cst6:* = cls.constructor;
trace(cst2 === cst3 && cst3 === cst4 && cst4 === cst5 && cst5 === cst6); //true
trace( cst == cst2) // false
I debugged into these codes and found that cst & cst2 had the same content but not the same object,
so why cst & cst2 don't point to the same object?
Also, I can create an object by
" var obj:Object = new cst();"
but
" var obj:Object = new cst2();"
throws an exception said that cst2 is not a constructor.
Anyone can help? many thanks!

I used "describeType" and found that "cst2" is actually "Class" class.
So,
trace(cst2 === Class); // true
That's what I want to know, Thank you.

Iterator Interface.A question please.

I am unable to grasp the meaning of the following below :
As we all know,Interfaces have abstract methods,(ie methods that
have no body) and any class that implements the Interface has to
implement the methods defined in the interface.That is,write the body for those methods.
So far so good.
Now coming to Collections called Vector.
We have the 'Iterator' interface implemented by the vector class.
The Iterator interface has the methods hasNext(),next().
and we have the following code in the our class which iterates thru'
the vector:
MyClass item;
while(iter.hasNext())
item = (MyClass)iter.next();
// Do something here.....
Now we are using the methods hasNext() and next() above.
But as they belong to the Iterator interface,(which means they
are basically methods with no implementations) then how is iteration
possible? We havent defined anything in the hasNext() method or the next()
so how does Java automatically start iteration
Has any one understood my question?Arent hasNext() and next() supposed
to be methods with no body???
If I am saying iter.hasNext(),that means hasNext() has been defined
somewhere to iterate thru the vector?
I am just confused regarding this issue as to how is hasNext() and next()
being implemented as I as the programmer have not implemented them
in my code
Please can some one answer my question?
Regards
Ajay

Thanks Will.
Regarding the question,then why define an Iterator interface when
the collection class implements the functionality?
Why not define the methods hasNext() and next() in the Object
class?
So by default,all classes extends the Object class ,we
cud use the hasNext() and next() method?
No??? Or am I wrong?

Thanks for yr reply.
So you mean to say the the Iterator methods hasNext()
and next()
are being implemented by the Vector class.right?Not exactly. The Vector class defines an inner class, and it is this class that implements the Iterator interface, and so these two methods. When you write code like
Vector myVector = new Vector();
// code to fill myVector...
Iterator it = myVector.iterator();the call to the iterator() method tells myVector to give you an instance of this inner class. The Vector class itself doesn't implement next() or hasNext().
Then why define an interface with these methods at
all?
Why not give concrete bodies to these methods and put
them in
the Object Class.If you did that, then all classes would inherit them - all classes would be iterators. That wouldn't make sense, though, as clearly not all classes are meant to be used to iterate over collections of objects.
Iterator is an interface so that a consistent API can be defined for iteration. As iterators are used in lots of different places, it is very helpful to have all of them guaranteed to have next() and hasNext() methods (amongst others). It is also very helpful to be able to call the iterator() method on any Collection class and know that the object that is returned, regardless of its implementation, will be of type Iterator.
Then we can call them polymorphically.???But that's what you're doing - Vector and ArrayList (for example) have different implementations of Iterator, but code that iterates over them doesn't need to know that. As both return objects that implement the Iterator interface, they are interchangeable; that's polymorphism at work.

What is ticket? Process flow ticket
Handling tickets is called Issue Tracking system. The errors or bugs forwarded by the end user to the support team are prioritized under three seviority High, Medium and Low. Each and every seviority as got its time limits before that we have to fix the error.
The main job of the supporting consultant is to provide assistance on line to the customer or the organisation where SAP is already implemented for which the person should be very strong in the subject and the process which are implemented in SAP at the client side to understand,to analyse,to actuate and to give the right solution in right time.This is the job of the support consultant.
The issues or the tickets(problems) which are arised is taken care of on priority basis by the support team consultants.
The work process in support projects are given below for your reference.
1. The customer or the end user logs a call through any tool or by mail (RADIX).
2. Each one of the support team is a part of support group.
3. Whenever a customer logs a call he /she has to mention to which work group (by name).
4. Once the calls came to the work group the support consultant or the team need to send an IR (Initial Response) to the user depending upon the priority of the calls. (Top,High,Med,Low,None)
5. Then the error is fixed, debugged by the support consultant or the team. Then after testing properly by generating TR(Transport Request through the basis admin)
6. Then it is informed to the end user/customer/super user about the changes which have moved to the production server by CTS process.
These are the process. In summary, what I understand is that if any configuration or customization is required to solve the issue, then the consultant have to work on DEV Client, then the end user will test it in the QA client and after approval the BASIS consultant has to transport it to the PRODUCTION client.
An example:
Tickets in SD can be considered as the problems which the end user or the employee in the company face while working on R/3. Tickets usually occur during the implementation or after theimplementation of the project. There can be numerous problem which can occur in the production support and a person who is working in the support has to resolve those tickets in the limited duration, every ticket has the particular deadline alert so your responsibility is to finish it before that deadline.
To begin with , we should give "TICKET" to you for not knowing it.
Here is an eg of a ticket raise:
End user is not able to
1. Create Sales order for a customer from a New plant , since shipping point determination is not happened . ( Without Shipping point the document becomes INCOMPLETE and he will not be able to proceed further like DELIVERY, BILLING).
He raises a ticket and the priority is set in one of the below:
1. Low 2. Medium 3. High.
Now you need to solve this ticket. You would analyze the problem and identify that the SP configuration has to be done for the new plant.
You would request a transport for DEV CLIENT to BASIS. You do the change and Request one more Transport to BASIS for QA client. The End user will test the same by creating a sales order for the new plant and approve it.
Finally, you request a transport to move the changes to PRODUCTION. Once the change is deployed in production the TICKET is closed. What I have given is a small example. You would get some real issues with severity HIGH in your day-day support.

Object class name does not exist in IDM

Hi Team
We are process of Integrating GRC 10.1 to Enterprise Portal.Followed accordingly as per the SAP Note No. 1977781.
While running the Schema Job, we get a message Schema Imported Suxcessfully. While running the Job : GRAC_REPOSITORY_SYNC_JOB, the job
shows successful, but a Warning Message : User Adaptor Empty in SLG1 T.code.
I have checked the Path suffix,connectors,data source and all are maintained but no sure about this warning message.
Secondly,I tried for test creation of user on Portal via GRC 10.1.I am getting below error
"Object class name does not exist in IDM" Please see log below
Request gets closed stating Auto Provisioning failed.Please advice if someone has faced same issue and the steps taken to rectify it.
Thanks
Nitesh

Hi Nitesh,
We worked on this issue for quiet sometime with SAP to get this finally fixed You can check all below mentioned notes.
First Check:
Please check the Note: 1915763 - Error Provisioning from GRC 10 to SAP Portal while adding or removing a role in Change Account request type.
This Note says that if your LDAP set as data source is read-only in Portal, then you need to change it to Modifiable in order to allow create or change user belonging to LDAP.
We have set the UME correctly and no longer read-only. But our access requests still used to fail with the following messages.
"Object class name does not exist in IDM".
Second Check:
Kindly ensure the field mapping for portal is done in IMG settings properly.
If it is fine please check below note 2033714 - AC10.0: error in SGL1 "Object class name does not exist in IDM".
This note is only to check if you have made any mistake with your portal mapping and doesn't address the correct issue.
Third Check:
Finally after implementing SAP note 1941250 - UAM: Truncated parameters provisioned on changing users from Access Request
our issue got fixed.

Madhu.

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!
