Predefined methods
What are predefined methods in web dynpro ?
Thanks,
sowmya
Hi Sowmya,
There are the standard hook methods:
The method wdDoInit() is called immediately after the controller has been instantiated. Preparatory work should be performed in this method.
The method wdDoExit() is called immediately before the controller is garbage collected. You should write code to perform clean up tasks in this method.
The method wdDoPostProcessing() is a hook for error handling during context validation.
The method wdDoBeforeNavigation() is a hook that allows you to implement your own navigation processing if you want to override the standard navigation.
The method wdDoModifyView() is called immediately before a view is rendered. This is the only place where you can to modify the viewu2019s UI elements.
Thanks,
Tulasi

Hi,
I was going through a tutorial. There they have used row.approve() for a row of a View object. I want to know what is the use of approve() method
Is it a predefined or user defined method
ThanksIt's not a predefined method.

hi, i simply want to know what is a setter method() ? is it a predefined method from javadocs ? or any body can define for setting up variable ?
It's the nickname for what is also called a "mutator", and is a method that conforms to the Java Bean specification for modifying the state of a private instance variable and is also one way to promote encapsulation.
Example:
class Foo
private String bar;
public setBar(String aBar) // setter
bar = aBar;
public getBar() // getter
return bar;

Hi,
I am new to BPM. I am trying the display("Hello!"); function to display the result of my variable. But i do not know where the method would dump the output.
Where do i see the output of this method. Is there some console where this value gets printed.
Please help.
Thanks
SumitHi Sumit,
To display the result of variable, you can make use of logMessage predefined method provided by ALBPM/OBPM.
logMessage("My value of variable: " + variable);
To view the result of the variable you can go to the logviewer tab.
There you can find the message as well as the value of your variable.
display function can also be used for this purpose but it will pop up the message at the run time. you can able to see it in your logviewer also.
If you are using ALBPM 6.0/OBPM 10gr3 then right click on the editor and select option Run this to view the message pop up.

assume variable a is 4.647 and i want to convert this to 4.5 . how can i round numbers like this. Is there is a predefined method in java to achive this.
I don't think java.lang.Math.round() will do what the original post asked for, since it rounds to the nearest long number. So you still would have to write your own method to round 4.647 down to 4.5.

How to extract an integer or a float value from a String of characters
Hi i have a problem getting to a float value within a string of characters..
for instance the string is
"numberItem xxxxxxxxx 700.0" (each x is a space..the forum wouldnt let me put normal spaces for some reason)
how do i store 700.0 in a float variable
remember the string is obtained from an inputfile
so far i got the program to store the inputfile data line by line in a String array..i tried tokenizing the string to get to the the float value but since i have mulitple spaces within my string, the token method only gets "numberItem" from the above String
This is all i have so far:
String c;
String Array[] =new String[g]; (i used a while loop to obtain g(the nubmer of lines in the file))
while((c=(cr.readLine()))!=null)
Array[coun]=c;
it would be reallllllllllllllllllllllllllllllllllllllly easy if there was a predefined method to extract numeric values from a string in java..

Not true.
Anyway why not use string split, split on spaces and grab the last element (which by the format you posted would be your 700.0)
Then there is the Float.parseFloat method.
It is easy.
And another thing why not use a List of Strings if you want to store each line? (And why did you post that code which doesn't really have anything to do with your problem?) Also in future please use the code formatting tags when posting code. Select the code you are posting in the message box and click the CODE button. -
How to find size of ResultSet in JAVA
hi ,
I have one problem... went for sun API but i did not get any solution....please any body help me... my problem is ......
I got the data from DataBase by executing a query . so my Resultset having some records.Now my problem is how to find the size of ResultSet.without converting into list or without wile loop I want to find out size of my ResultSet
..... Is there any predefined method for that;

hay.... again you are diverting from topic. my problem is how to find resultset size.... not for how to write query for counting records.Of cousre he is. Because the answer to your question is: it can't be done. So he's kindly moved on, and offered you an alternative way to achieve what you want. If that offends you, I suggest you have your head in an uncomfortable and unsuitable orifice
Why are you so desperate to know the size of the ResultSet anyway? If you've got limits on the size of ResultSet that's acceptable, you can adjust your query to limit the number of rows returned. if you simply need to know how many rows there are, pulling the entire content of the table(s) back and counting them afterwards is horrifically inefficient. If you need to know to so you can prepare a datastructure to put the results in, maybe you've chosen the wrong structure (I'm thinking 'array' here). You might have a legitimate reason to find out the size of a ResultSet, I don't know. But the ResultSet interface doesn't give you that option, so you're on a hiding to nothing, and might as well use the suggested alternative, or reconsider your requirement -
Need Ways to implement Badis in ECC 6.0 (Enhancement Points)
Hi experts,
I am new to BADIs. I've a requirement to find a BADI for changing Customer number while posting customer invoice in SAP (the data is coming from XI system in IDOC format). I want to know any BADIs or userexits are there for my requirement. At the same time I want to know how to implement a BADI in ECC 6.0 .Any docs releated to this topic will be of great help.
points will be awarded for sure..........hi Poorna Chandras... ,
These steps should enable you to find any BADI related to any transaction in a matter of minutes.
Procedure 1:
1) Go to the transaction SE37 to find your function module.
2) Locate the function SXV_GET_CLIF_BY_NAME.
3) Put a breakpoint there.
4) Now open a new session.
5) Go to your transaction. 6) At that time, it will stop this function.
7) Double click on the function field EXIT_NAME.
8) That will give you name of the BADI that is provided in your transaction.
Business Add-Ins
Procedure 2:
1) Goto se24 (Display class cl_exithandler)
2) Double click on the method GET_INSTANCE.
3) Put a break point at Line no.25 (CASE sy-subrc).
4) Now Execute SAP standard transaction
5) Press the required button for which you need to write an exit logic, the execution will stop at the break point.
6) Check the values of variable 'exit_name', it will give you the BADI name called at that time.
7) This way you will find all the BADIs called on click of any button in any transaction
SAP Business Add-Ins (BAdIs) are one of the most important technologies used to adapt SAP software to specific requirements. BAdIs were introduced with Release 4.6 and replace function module exits. This technology is not limited to SAP applications. BAdI calls can be integrated in customer applications. These can then be enhanced by other customer applications. In the various SAP applications, BAdI calls are implemented at places where enhancements are appropriate.Business add-ins are enhancements to the standard version of the system. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery. Since specific industries often require special functions, SAP allows you to predefine these points in your software.
In contrast to customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, country-specific versions, industry solutions, partner, customer, and so on). You can create definitions and implementations of Business Add-Ins at any level of the system landscape.SAP guarantees the upward compatibility of all Business Add-In interfaces. Release upgrades do not affect enhancement calls from within the standard software nor do they affect the validity of call interfaces. You do not have to register Business Add-Ins in SSCR.
The Business Add-In enhancement technique differentiates between enhancements that can only be implemented once and enhancements that can be used actively by any number of customers at the same time. In addition, Business Add-Ins can be defined according to filter values. This allows you to differentiate between Add-In implementations using the filter Country or other criteria.
The enhancement technique is set up in such a way that it is possible to define interfaces for ABAP soure code, screens, GUI interfaces, and tables. These allow customers to include their own enhancements in the standard. A single Business Add-In contains all of the interfaces necessary to implement a specific task.
BADI is just an object-oriented version of user-exit. Instead of entering program code into some function module (as in customer-exit), you define some class which has to implement predefined methods and those methods are fired at predefined points just like an old user-exit. Some BADI can have multiple independent implementations which is much better for software deployment as several developers can implement the same BADI independently. BADI/UserExists are used to enhance R/3 For customer Needs.
Actually there is no transaction to find when and where the BADI
is called.
1. You can see the BADI description to find why it is called.
2. Once you implemented and activated the BADI, put some break points
in the BADI and see "where else used" option to check in what all
programs this BADI is called. In the ITS debug, when you are doing
the operation what exactly the BADI description tells, it will take
to the break points and you have to do manually debug the whole thing.
I know its bit difficult to do manual debug the whole thing, it
takes lot of time, but you have to be very patience when you are
dealing with BADI's.

What is command design pattern? what is the problem that it solves?
Hi i have been reading few articles on command design pattern but was unable to understand what it is and what problem does it solve. As far as my understanding goes if there is a pre specified method in an object that could execute and perform the necessary activities then it is called as command design pattern. Why is it named as command design pattern, it is because in a shell we use commands to retrieve output. For example when we type "dir" in dos command prompt it returns the list of files. so here we have to remember a preexisting exe file named "dir" which does something when used. So here like we call it command because when "dir" is passed to the computers it returns something that is expected. may be the computer obeys the command issued and return something back. So like wise if there is a method that is defined as as the command, for example in struts framework the action class must have a method "execute()" which is called by the framework to execute the necessary action mapped to it. So if there is a predefined method like "execute" in struts then the object is said to be followed command design pattern. So what actually does it solve?
What ever i have written is my understanding from the articles i have read about the design pattern. So kindly correct me if i am wrong. Help me understanding what actual problem does this pattern solves. Thanking you in advance.This is really off-topic for these forums. You might do better on StackOverflow.com. I'll just say that although the first Design Patterns book came as a revelation to me, it was more for (a) the nomenclature (decorator, factory, facade, etc) which is still with us and (b) about five of the original patterns, which told me things I didn't already know. I've never used any of the others, including Command, and the whole design patterns thing quickly degenerated into farce with what seemed like a sustained attempt to reduce the whole of computer science to design patterns, which really isn't the point. As an example, there is one in another book called Type Object, which is nothing but 3rd normal form, which can be defined roughly in a couple of sentences. This pattern went on for dozens of pages with a very artificial example. I wrote to the mailing list about it: 'Type Object considered hilarious'. I got a rude reply from the original author, which I guess I expected, but also an incredible response from the list owner, saying I should recast my objections in the form of a design pattern. That lost it for me. True story. Moral: don't take this religion, or any IT religion, too seriously. They come around every 18 months or so with the regularity of the next bit of Moore's Law. I've seen dozens of them come and go since 1971, all with something to say, all 90% nonsense.

ABAP String code for String.IndexOf("str")
Hi,
I'm totally new to abap. How can I determine iif one string is in another?
Thanks,
DougHi Doug,
we have the comparison operator CS (contains string).
IF 'My brother loves it' CS 'other'.
evaluates TRUE.
System variable SY-FDPOS will carry the offset where the string starts, here 5.
Although we have ABAP objects now for some time, we are far away from languages like JAVA where all data objects are classes with predefined methods.
But you are welcome to implement something comparable.

What is business add-ins and business transaction events
Dear All,
Would you mind tell me what it sht business add-ins and business transaction events ?
i still not understand about this after i read the training material

As with customer exits, two different views are available:
· In the definition view, an application programmer defines exit points in a source that allow specific industry sectors, partners, and customers to attach additional coding to standard SAP source code, without having to modify the original object.
· In the implementation view, the users of Business Add-Ins can customize the logic they need or use a standard solution, if one is available.
In contrast to customer exits, Business Add-Ins no longer assume a two-level infrastructure (SAP and customer solutions), but instead allow for a multi-level system landscape (SAP, country-specific versions, industry solutions, partner, customer, and so on).

To find the BADI to be implemented and then implement this via SE19.
These steps should enable you to find any BADI related to any transaction in a matter of minutes.
Procedure 1:
1) Go to the transaction SE37 to find your function module.
2) Locate the function SXV_GET_CLIF_BY_NAME.
3) Put a breakpoint there.
4) Now open a new session.
5) Go to your transaction. 6) At that time, it will stop this function.
7) Double click on the function field EXIT_NAME.
8) That will give you name of the BADI that is provided in your transaction.

Procedure 2:
1) Goto se24 (Display class cl_exithandler)
2) Double click on the method GET_INSTANCE.
3) Put a break point at Line no.25 (CASE sy-subrc).
4) Now Execute SAP standard transaction
5) Press the required button for which you need to write an exit logic, the execution will stop at the break point.
6) Check the values of variable 'exit_name', it will give you the BADI name called at that time.
7) This way you will find all the BADIs called on click of any button in any transaction

Business Transaction Events
Business Transaction Events (Open FI) The Open FI enhancement technique was developed in the Financial Accounting component. Open FI is based upon the following principles: Application developers must define their interface in a function module, an assignment table is read in the accompanying (generated) code, and the customer modules assigned are called dynamically. This technique differentiates between enhancements that are only allowed to have one implementation and enhancements that can call multiple implementations in any sequence desired. Both industry-specific and country-specific enhancements may be defined.
SAP business transaction events are one type of customer enhancements provided by SAP! We can access the business transaction events using FIBF.Next we have to find the process interface for duplicate invoice check!

hi all ,,
can any one tell me how to create a exception class in ABAP OOPS concept ??
if possible can give link also for documentHI Jayakumar,
Please go thru this document
Exceptions are represented by objects that are instances of exception classes. Defining an exception is, therefore, the same as creating an exception class.
All exception classes must inherit from the common superclass CX_ROOT and one of its subordinate classes:
CX_STATIC_CHECK
CX_DYNAMIC_CHECK
CX_NO_CHECK
. The assignment of exception classes to one of these three paths of the inheritance hierarchy determines the way in which the associated exceptions are propagated. There is a record of predefined exception classes CX_SY_... whose exceptions are raised in error situations in the runtime environment. These classes all inherit from CX_DYNAMIC_CHECK or CX_NO_CHECK but not from CX_STATIC_CHECK (see hierarchy in the ABAP keyword documentation).
All exception classes must begin with the prefix CX_. They are usually defined globally with the Class Builder of the ABAP Workbench. Local exception classes can, however, also be defined.
Individual (abstract) exception classes that are used as the superclass of further exception classes can be defined. The exceptions of the subordinate classes can be handled together using a superclass.
Exception classes have the following features:
Constructor
The constructor must have a predefined structure and a specific interface. With global classes, the Class Builder generates the correct constructor and sets it to an unchangeable status. The constructor has two IMPORTING parameters:
TEXTID of the SOTR_CONC type
This parameter can be used to determine which of your exception texts the exception will use.
PREVIOUS of the CX_ROOT type
This parameter can be used to assign the PREVIOUS attribute a previous exception.
Methods
In exception classes, you can define your own methods. The following two predefined methods are inherited from the root class CX_ROOT:
GET_TEXT
Sends back the exception texts of a class (controlled by the TEXTID attribute) as a string.
GET_SOURCE_POSITION
Returns the program name, the name of a possible include program, and the line number of the statement that raised the exception.
Attributes
The attributes of exception classes are used to transport additional information on an error situation to the handler. The main piece of information is, however, always the fact that an exception of a particular class has occurred. The following attributes are inherited from CX_ROOT:
TEXTID
Used to specify the exception of a class more precisely by using several exception texts. Is evaluated in the GET_TEXT method.
PREVIOUS
If an exception is mapped to another exception, a reference to the original exception can be defined in this attribute via the EXPORTING addition of the RAISE EXCEPTION statement and by means of the constructor IMPORTING PARAMETER with the same name. This can result in a chain of exception objects. In the event of a runtime error, the exception texts of all the exceptions in the chain are output. Mapping an exception to another exception is only beneficial if the context in which the original exception occurred is important for characterizing the error situation.
KERNEL_ERRID
The name of the associated runtime error is stored in this attribute if the exception was raised by the runtime environment, for example, COMPUTE_INT_ZERODIVIDE with a division by zero. If the exception is not handled, precisely this runtime error occurs.
Parameters cannot be transferred to the constructor for this attribute. If the exception is raised with RAISE EXCEPTION, the attribute is set to initial.
Global Exception Classes
Global exception classes are defined and managed in the Class Builder. If the correct naming convention (prefix CX_) and the class type Exception Class is chosen when a new class is created, the Class Builder automatically becomes the Exception Builder.
The Exception Builder offers precisely the functionality required to define exception classes and generates independently-defined components that must not be changed. When classes are created, the category of the exception must be specified, in other words, whether it is to inherit from CX_STATIC_CHECK, CX_DYNAMIC_CHECK, or CX_NOCHECK.
Tab Pages of the Exception Builder
The Exception Builder has the tab pages Properties, Attributes, Methods, and Texts.
The properties do not normally need to be changed.
Except for the four inherited attributes mentioned above, further public attributes can be generated by the Exception Builder. The contents of these attributes specify the exception more clearly and manage the exception texts.
All of the methods are inherited from CX_ROOT. New methods cannot be added. The instance constructor is generated automatically. It ensures that, when an exception is raised, the attributes have the right values. It also transfers the text of the superclass for an exception class whose exception text is not specified explicitly.
The instance constructor is generated on the basis of the attributes, which are set up on the basis of the exception texts. Changing the attributes in superclasses can, therefore, invalidate the constructors of subordinate classes. The constructors of subordinate classes can be regenerated under Utilities ® CleanUp ® Constructor.
Texts are a special feature of exception classes and the Exception Builder. For further information, refer to Exception Texts.
Local Exception Classes
Local exception classes can be defined for specific exceptions that only occur within one single ABAP program. The condition for a local exception class is that it inherits from one of the three classes CX_STATIC_CHECK, CX_DYNAMIC_CHECK, or CX_NO_CHECK, or from their subordinate classes. An individual constructor and individual attributes can be created. Individual methods should not be created, however, and the methods of superclasses should not be redefined.
Examples of Local Exception Classes
report DEMO_LOCAL_EXCEPTION_1.
class CX_LOCAL_EXCEPTION definition
inheriting from CX_STATIC_CHECK.
endclass.
start-of-selection.
try.
raise exception type CX_LOCAL_EXCEPTION.
catch CX_LOCAL_EXCEPTION.
message 'Local Exception!' type 'I'.
endtry.
This example shows a minimal local exception class, which is simply the local representation of one of the three direct subordinate classes of CX_ROOT. It can be used in the program.
report DEMO_LOCAL_EXCEPTION_2.
class CX_LOCAL_EXCEPTION definition
inheriting from CX_STATIC_CHECK.
public section.
data LOCAL_TEXT type STRING.
methods CONSTRUCTOR importing TEXT type STRING.
endclass.
class CX_LOCAL_EXCEPTION implementation.
method CONSTRUCTOR.
SUPER->CONSTRUCTOR( ).
LOCAL_TEXT = TEXT.
endmethod.
endclass.
data OREF type ref to CX_LOCAL_EXCEPTION.
start-of-selection.
try.
raise exception type CX_LOCAL_EXCEPTION
exporting TEXT = `Local Exception`.
catch CX_LOCAL_EXCEPTION into OREF.
message OREF->LOCAL_TEXT type 'I'.
endtry.
In this example, the exception class from the previous example is extended to include an individual attribute and constructor. The IMPORTING parameter of the constructor must be supplied when the exception is raised (it is required here). The attribute can be evaluated in the handler of the exception.
report DEMO_LOCAL_EXCEPTION_3.
class CX_LOCAL_EXCEPTION definition
inheriting from CX_SY_ARITHMETIC_ERROR.
public section.
methods CONSTRUCTOR importing SITUATION type STRING.
endclass.
class CX_LOCAL_EXCEPTION implementation.
method CONSTRUCTOR.
SUPER->CONSTRUCTOR( OPERATION = SITUATION ).
endmethod.
endclass.
data OREF type ref to CX_LOCAL_EXCEPTION.
data TEXT type STRING.
start-of-selection.
try.
raise exception type CX_LOCAL_EXCEPTION
exporting SITUATION = `START-OF-SELECTION`.
catch CX_LOCAL_EXCEPTION into OREF.
TEXT = OREF->GET_TEXT( ).
message TEXT type 'I'.
endtry.
In this example, an exception class is derived from one of the predefined exception classes for error situations in the runtime environment. An individual constructor is defined with an individual IMPORTING parameter that supplies the superclass constructor with this parameter. When the exception is handled, the exception text, as defined in the superclass, is read with GET_TEXT. -
I want to draw cordinate axes(X and Y) along the edges of my drawing area. I want that the cordinate axes are scaled. I mean number should appear at regular interval( user defined). Is there any predefined method to do that. Or I have to draw axes as line2D and manually write numbers over it. Or is there any other solution.
I will be very thankful for the help provided.Take a look at the Java 2 Tutorial under >UISwing>Components>Example-Swing, there is some sample code on ScrollDemo.java that might do the job.
