Small query on methods of classes

Hi,
I have a small query abt calling methods in oops...How will we get the exporting,importing and exception parameters when we r calling the methods manually without the patterns options ????

Well, the best way is of course to use the pattern, but you could also view the signature through SE24.
Transaction SE24
Enter class name, click display/change.
Click on methods tab.
Click your method.
Click the parameters button.
This will show you the signature of the method, including the importing, exporting, changing, and returning parameters.
Regards,
Rich Heilman

JVM crash when adding method to class

Hello,
I am getting some kind of problem with the virtual machine. The JVM crashes when making a class (with new). It happened when I was adding some functionality to the class, I worked my way backwards and discovered it crashes when I add any new methods, if I comment them out again everything works, adding a method by any name causes to crash.
I went in debug to find out where it was happening, and it happens on this line:
public PerspectiveActionToolBarHeader createPerspectiveActionToolBarHeader() {
     PerspectiveActionToolBarHeader ret = null;
     ret = new PerspectiveActionToolBarHeader(this); // << here
     return ret;
}The PerspectiveActionToolBarHeader is the class where adding methods causes it to fail. For example, it has the method
public Container getContainer() {
     return this;
}and works, but if I add:
public void anything(){} it causes a crash on the new PerspectiveActionToolBarHeader(this);
When stepped into with the debugger it goes to the (source not found) ClassNotFoundException and eventually before the crash the (stack?) looks like this:
Launcher$AppClassLoader(ClassLoader).loadClass(String) line: not available
MaldiSoftwareOptionsUIEnsemble(PerspectiveUIEnsemble).createPerspectiveActionToolBarHeader() line: 72
and the debugger describes the class just before the crash:
Launcher$AppClassLoader (id=44)
arg0     "saiman.uiobjnew.PerspectiveToolBarButton" (id=51) << has just changed
and the log file (not sure how much to copy here!):

I think I may have stumbled across the answer, It seems that the abstract class PerspectiveToolBar implements
the interface with the method public Container getContainer() but does not declare it, this should be fine because the method is abstract but it crashes. When I add the method public abstract Container getContainer(); to the abstract sub-class there is no error. I'm going to try make a small compilable example to see if I can reproduce it.
edit its actually only one of the two interface methods, and not getContainer(), but another one. If anyone is interested here is the interface:
public interface IMassSpectrometerPassableControlContainer
     Container getContainer();
     void reloadWidgetsOnVisible(boolean visible);
}and it works only if there is "public abstract void reloadWidgetsOnVisible(boolean visible);" in the abstract class PerspectiveToolBar implementing IMassSpectrometerPassableControlContainer.
I tried to reproduce it, but I can't get another class to repeat the behaviour, so I don't think I can post a bug report on it. Here is my attempt anyway:
import javax.swing.JToolBar;
* Class     Test.java
* Date:     7 Jun 2011
* @author     tofuser
public class Test extends Subclass
     public static void main(String args[])
          System.out.println("in main method");
          Test t = new Test();
          t.interfaceMethod();
     @Override
     public void interfaceMethod()
          System.out.println("interface method");
abstract class Subclass extends JToolBar implements Interface
     private static final long serialVersionUID = 1L;
     //this line is where it breaks in my code, including it works
     //public abstract void interfaceMethod();
interface Interface
     public abstract void interfaceMethod();

Sql Query in Custom Java Class in OIM 9x

Hi All,
I m having requirement where I need to execute SQL Select Query in custom java class.
The class is a action class ,in a method I m trying to execute SQL Query as below
     sdkDataSet = new tcDataSet();
          dataprovider =sdkDataSet.getDataBase();
               //sdkDataSet = new tcDataSet();
               sdkDataSet.setQuery(dataprovider, sdkQuery);
               sdkDataSet.executeQuery();
               logger.debug(CLASSNAME + methodName + "Query Executed");
               if (sdkDataSet.getRowCount() > 0)
                    sdkName = sdkDataSet.getString(0);
                    logger.debug(CLASSNAME + methodName+ "The sdkName is " + sdkName);
Error is returned in logs
tcDataSetException    Must set a query before executing
I hope issue is coming due to dataprovider dbrefence.
Kindly let me know how to execute sql query in a action class.

Creation of Material using BDC Session method & global class

Hi
Creation of Material using BDC Session method & global class by using oops.
can anyone plz help me out

Hi,
it looks like it's not possible to call this BAPI wihtout material number. Here is a quote from BAPI documentation.
When creating material master data, you must transfer the material
number, the material type, and the industry sector to the method. You
must also enter a material description and its language.

Internal table in method of class (BADI)

Hello people !!
I need to use an internal table into method of class. I don´t know very well how to use it. I know that it hasn´t a header; but I don´t know how to defined and use it.
I need to use in a method of badi.-
I will be grateful by the help that your could offer to me.-
Thank you so much,
Esther.-

Thank you for your answer.
But, I had defined as de fist item, but I had defined with a structure of dictinary.
Now, in my code, I need to deposit information to the above mentioned table. Then, when I try to accede to the fields of the estructure, when I compile it gives me the following mistake:
"ACC_DATA" is a table without a header line and therefore has no
component called "CUENTA".
I attach departs from the code:
types: es_accdata type standard table of Z_ES_ACCDATA.
data: acc_data type es_accdata.
      loop at it_mseg into r_mseg.
      si es Entrada de Mercancía
        if r_mseg-bwart = '101'.
          at first.
            acc_data-cuenta = r_mseg-sakto.
            if not r_mseg-kostl is initial.
              acc_data-centro_coste = r_mseg-kostl.
            else.
              acc_data-orden_inversion = r_mseg-aufnr.
            endif.
          endat.
          monto = monto + r_mseg-dmbtr.
        endif.
      endloop.
Thank you againg, for a new answer !!!!

Select query in method    endmethod

Hi all,
      I am writing code in a method which is not accepting into table in select query, How to pass data into internal table using select query in method. As per my knowlegde we have to write code using field-symbols. can anybody please help me.
Thanks in advance.
Ranjith

it is possible to do a select into table. in your case the exporting parameter may be defined normal structure. if you want to define the internal table you have to use table types to behave the parameter as Internal table.
exporting
e_flight    type sflight_1ab1
select * from sflight
into table e_flight
up to 30 rows.

(view hint or Query writing method) using views in Select Query

Need Assistance,
Hi all,
My database having many views. while i am joining the views in a select query increase the cost of the querys due to the complex joins in the conditions.
While checking the select query with views individualy taking less cost.
Does any hint or query writing method is availabe to avoid the merging of the execution plan of the views?
I have browsed many related to the mentioned issues,couldn't found any thing that helps me.
Please help me on this issue,it will be very much helpfull for me.
Thanks,

Please read the two threads linked to in the FAQ: {message:id=9360003} and post the relevant details they request, so that people can help you better with your issue.
We cannot help if you just say "my query is slow what do I do to fix it" as we cannot see your queries, your data, or any other information we would need to help. If the answer was that simple, it would be built into oracle so that the optimiser would fix it for you.

Class-data versus data and methods versus class-methods in OO ABAP

Hi
I was going thorugh following OO ABAP code.
CLASS vessel DEFINITION.
PUBLIC SECTION.
    METHODS: constructor,
             drive IMPORTING speed_up TYPE i,
             get_id RETURNING value(id) TYPE i.
    CLASS-METHODS: start,

                   inheritance,

ENDCLASS.
Whats is difference between methods and class-methods ?
What is the difference between data and class-data ?

Hi Rajesh,
There are two types of componenets in a class
1)Static components
2) Instance components
Instance components exist for every instance of the class, while static exist only once for any number of instances of the class.
Components of the class are methods, attributes, events etc.
static attributes are represented by CLASS-DATA and instance attributes are represented by DATA.
static methods hence are done by CLASS-METHODS and can access only static attributes.
Instance methods are done by METHODS and can access any attribute.
For eg: supposing that in a class, there is a static attribute. Suppose after one instance is created, we are setting this static attribute value as 10. Now we are creating another instance of the same class. Now when you try to display the value of this attribute, it will be 10.ie. it needs to be initialized once and can be shared between instances.
Just go through this document..You will get nice info from this.

Can we query more than one class in a call to .tmib

Hi,
i am creating a utility to monitor the applications at run time using mib.any
body have an idea if we can query more than one class in one call to .tmib.
thanks
roopesh

That would be an interesting enhancement, perhaps using Embedded FML to
pack multiple MIB requests into one buffer.
Product Management makes all decisions about major enhancements, and it
is based on customer need, so that's where the requests should go.

Abstract method and class

I'm a beginner in Java and just learn about abstract method and class.
However, i am wondering what is the point of using abstract method/class?
Because when I delete the abstract method and change the class name to public class XXXX( changed from "abstract class XXXX), my program still runs well, nothing goes different.
Is it because I haven't encountered any situation that abstract method is necessary or ?
Thanks!

Yes - you probably haven't encountered a situation where you need an abstract.
Abstract classes are not designed to do anything on their own. They are designed to provide a template for other classes to extend by inheritance. What you have build sounds like a concrete class - one which you are creating instances of. Abstract classes are not designed to be ever instantiated in their pure form - they act like a partial building block, which you will complete in a class which extends the abstract.
An example might be a button class, which provides some core functionality (like rollover, rollout etc) but has an empty action method which has to be overwritten by a relevant subclass like 'StartButton'. In general, abstract classes may not be the right answer, and many people would argue that it is better to use an interface, which can be implemented instead of extended, meaning that you can ADD instead of REPLACING.
Not sure if that helps.. there are whole chapters in books on this kind of thing, so it's hard to explain in a couple of paragraphs. Do some google searches to find out more about how they work.

Method addTextUrlColumn (Class oracle.jbo.html.databeans)

The method addTextUrlColumn (Class oracle.jbo.html.RowSetBrowser) adds an additional column to the View's RowSet. This column will be appended after all of the colummns that represent attributes belonging to the RowSet. How can I insert a additoinal column before all of the columns of the RowSet instead?
Thanks
Yoo

The RowsetBrowser doesn't support this by default, you have source code to this control. You can extend it's features by adding this capability. Look at the source code in bc4jhtmlsrc.zip

Quick tutorial of using methods of class

Hi,
I have never use methods of class before. Is there anyone can give me a quick tutorial how to do it?
To be more specific I need convert field 'DAUER' into the required format using one of the following methods of class 'CL_HR_T510_PSRCL':
     CONVERT_DURATION_TO_MMMM: Duration Conversion to Format 'MMMM'
     CONVERT_DURATION_TO_MMMM: Duration Conversion to Format 'YYMM'
Please be more detailed in describing it.
Your help will greatly appreciate.
Thanks,
Veb

Hello Veb,
You will find at this sdn page at section ABAP Objects , documentations and links about ABAP OO :
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/webcontent/uuid/35eaef9c-0b01-0010-dd8b-e3b0f9ed7ccb#section7 [original link is broken]
For your example :
1) You can use like this :
CALL METHOD CL_HR_T510_PSRCL=>CONVERT_DURATION_TO_MMMM
EXPORTING
    DURATION = old_duration
RECEIVING
    MMMM     = new_duration.
1) Like this :
l_dauer = convert_duration_to_mmmm(
                             duration = l_dauer).
Best regards
