Creating object of subclass.

Hello All,
I have a query. In ServletFilter's doFilter method I got the object of ServletRequest. Now I have to get the header. How do I get the header since getHeader method is in HttpServletRequest class which is the subclass of ServletRequest. Any one having any idea ?.
Thanks and regards,
Sachin

In a webapp, the ServletRequest passed in will be an HttpServletRequest. Cast it to HttpServletRequest and you will be able to get the header.

ABAP OO: Duplication of selected data in created objects?

I am new to ABAP OO and I have a conceptual question/concern that I cannot resolve. Can someone explain what I am missing?
I would think that selecting and storing (in internal tables) a large amount of data from many related database tables and, at the same time, creating and storing objects from this same data would unnecessarily consume a huge amount of memory. To avoid this problem, it seems that the selected data and created objects should not be stored in internal tables simultaneously.
Does this concern make sense? If so, how is this problem best handled?
Does it make sense to delete the corresponding data once the objects are created (to free memory)?
Or does it make sense to keep the data and only temporarily create objects as needed?
Thanks.

Hello Matt
The approach you describe is to select data first and the feed the object instances with them. Why not let the object instances do the data selection themselves?
I will give you an example what I mean.
(1) Lets assume I want to write an application that allows to deal with cost center hierarchies. On the selection screen you can choose one or many cost center hierarchies.
(2) Using the selection criteria I would select all cost center hierarchies but without any details (just the key values).
(3) Next I would loop over the cost center hierarchies and create a cost center hierarchy instance (a class you have to define yourself) for each key value. The CONSTRUCTOR of this class will have an IMPORTING parameter like id_kostl_hier.
(4) In the CONSTRUCTOR method I first check if the cost center hierarchy exists (if not raise an exception-class based exception) and then do the selection of the hierarchy details (e.g. the cost centers).
(5) The instances are collected in an itab of the "frame" application.
Using this approach you will have little duplication of data within your application. Furthermore, if you really have to deal with huge amounts of data then you could read them only on demand (like in tree controls where the sub-nodes usually are read when the parent node is expanded).
Hope I could give you some fresh insights into this exciting topic.

Uwe

ABAP OBJECTS: Dynamic Create object

Hi folks!
I have a problem... I need to create a dynamic type object with:
DATA: my_instance TYPE REF TO class1.
CREATE OBJECT my_instance TYPE (class2).
* where class1 is a superclass of class2.
When I do:
my_instance ?= m_parent.
* where m_parent is an instance of class1
My problem is when I want to access to an attribute of the class2, the compiler says that it cannot find the attribute (this is OK, because the attribute is only in the class2).
My question:
Is there anyway to access to an atribute of second class when is not in the first class? (i don't want to create the attribute as an attribute of the first class).
Thanx!!!!

Hi David,
When you do the debugging, you are dealing with run-time - i.e., the program is now running and you are just interrupting it at each statement to examine the program state. You will reach the point where the object is already created. That is why you can see all those attributes. But when you comiple, the program is not yet running, so the attributes will be unknown because of the dynamic type specification.
I think you will have to redesign the program logic. As i had already said in my earlier post, it is not proper to have the attributes specified statically while the class itself is specified dynamically.
Your situation is somewhat similar to -
DATA ITAB TYPE TABLE OF SPFLI.
PERFORM TEST TABLES ITAB.
FORM TEST TABLES ITAB.
LOOP AT ITAB.
WRITE: / ITAB-CARRID.
ENDLOOP.
ENDFORM.
Hope the point is clear.

Anand Mandalika.

Creating objects when count is greater than 1

Hi
I'm trying to create a runbook that checks service manager for incidents that have been created in the last 10 minutes of the same category. When the result of this check brings back more than 5 objects I want a problem to be created with the incidents linked
to the problem.
I know a junction will be required somewhere in order to stop the create object running multiple times but when this occurs I cannot address the scobject guids in the create relationship step. I have attached a screenshot of the runbook below.
Thanks

Hi,
Flatten the "Get Object Count" Activity so it triggers only once.

Yes, I want to create object-relational schema from DTD.

Thank you for reply~~
I want to create object-relational schema from DTD using object type or collections as mentioned.
In reply, it is impossible.
But, I read Oracle supports storing an XML document with object-relation. I executed storing sample, but I had to create schema manually.
Is it really impossible to create OR schema from DTD automatically?

Yes. You need to create your database schema before insert XML data to it.

Use Granfeldts Create Object to create dynamic groups

Trying to use Sorens Granfeldts, Create Object WF activity to create dynamic groups.
In a standard function evaluator activity I generate the Filter as [//WorkflowData/Filter]
The "string" I set it to is:
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Dialect="http://schemas.microsoft.com/2006/11/XPathFilterDialect" xmlns="http://schemas.xmlsoap.org/ws/2004/09/enumeration">/Person[ObjectID
= /*[ObjectID = '8dfcb5e8-ff01-400c-8ca7-2a0002d2d2d4']/ComputedMember]</Filter>
In the CreateObject activity I then just have [//WorkflowData/Filter],Filter among the initial values.
The creation works if I remove this attribute so the rest of the attributes seems to be working.
The creation fails however end I get the error below in the Forefront Identity Manager event log.
System.NullReferenceException: Object reference not set to an instance of an object.

Have anyone used this WF activity to create dynamic groups and can tell how to set the Filter?

Hey Kent!
I did the same thing, with Søren`s Create Object WF. I did it like this on the filter part:
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Dialect="http://schemas.microsoft.com/2006/11/XPathFilterDialect" xmlns="http://schemas.xmlsoap.org/ws/2004/09/enumeration">/Person[(Department = '[//Target/ObjectID]')]</Filter>,Filter
The whole thing looks like this:
(I use Function evaluator to generate a AccountName for groups based on a clean version of DisplayName).
[//Target/DisplayName],DisplayName
SEC_[//WorkFlowData/CleanAccountName],AccountName
[//Target/Manager],Owner
Security,Type
DOMAIN_STRING,Domain
Universal,Scope
[//Target/DisplayName]_SecGroup,Description
[//Target/Manager],DisplayedOwner
None,MembershipAddWorkflow
True,MembershipLocked
[//Target/CleanAccountName],MailNickname
<Filter xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Dialect="http://schemas.microsoft.com/2006/11/XPathFilterDialect" xmlns="http://schemas.xmlsoap.org/ws/2004/09/enumeration">/Person[(Department = '[//Target/ObjectID]')]</Filter>,Filter

ABAP OO, Creating object dynamically

Hi everybody,
 Im currently working on some Abap OO examples. Everything is working ok except for the following: Creating objects dynamically.
This is what Id like to do:
Lets say we obtain a bunch of sales orders using a simple select statement and place them in an internal table. For each entry in our internal table, Id like to generate a new sales order object. This salesorder object is a simple class with a constructor with an Id and some other attributes.
When this is done, Id like to append every object to a new object, say basket, so that this basket contains something like an internal table within each record a reference to the salesorder. Is this easy to do? Im using the example that is described in the sap guide (create object pointer type (class_name) but it looks to me that you still have to declare the reference variables before you can create the object.
Hmm, I think Java is better suited for a job like this.
Hope you can help,
Cheers and Best wishes
Laurens Steffers

Hi,
Its not all that difficult in ABAP as well. The following code is based on Chapter 5, Listing 5.20 from book ABAP Objects.
What you need is an internal table of type <your sales object> e.g.
DATA: BEGIN OF obj_sales_order
 sales_order_no LIKE <sales_order_no_type>,
 <...>,
 objref TYPE REF TO <SALES_ORDER_CLASS>
 END OF obj_sales_order,
 reftab LIKE SORTED TABLES OF obj_sales_order
 WITH UNIQUE KEY sales_order_no
 <other key attributes>.
Now all you need to do is to do a SELECT...ENDSELECT loop, and:
SELECT ...
obj_sales_order-sales_order_no = <selection result>
obj_sales_order-<other key attr> = <selection result>
READ TABLE reftab INTO obj_sales_order
 FROM obj_sales_order.
IF sy-subrc <> 0.
CREATE OBJECT obj_sales_order-objref
 EXPORTING ...
 EXCEPTIONS ...
IF sy-subrc <> 0.
 MESSAGE ...
 CONTINUE.
ELSE.
 INSERT obj_sales_order INTO TABLE reftab.
ENDIF.
ENDIF.
CALL METHOD obj_sales_order-objref-><method>.
ENDSELECT.
Hope this help.

How can I create Object Tag which supports Sun and MS JVM both.

Hi,
I have created object tag as shown below
<object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
name = "TestApplet" height="0" width="0" >
<param name="code" value="com.apps.TestApplet.class" />
<param name="codebase" value="codes" />
<param name="archive" value="TestApplet.jar" />
</object>
The above tag is working fine with the below JVM combinations in Windows XP.
1) Only Sun JVM
2) Only MS JVM
3) Sun JVM & MS JVM
But these conditions are not working with Windows 2000.
How we can create object tag which will support for these two opertating systems?

I am not able to understand the problem. From my understanding, you have an applet which you are trying to display in a browser using <object> tag. If that is the correct then all it matters is the browser and the JRE�
For example the below code when put in a JSP or a HTML, will use JRE 1.6.0_01 that is available on the client machine. If that is not available on the client machine then it will try and download automatically in IE.
This below code is for IE� if you are using Mozilla Firefox then you need to change the �classid� attribute to �java: com.foo.bar.ui.MyClass�
<OBJECT ID="Gantt" classid = "clsid:CAFEEFAC-0016-0000-0001-ABCDEFFEDCBA"
 codebase = "http://java.sun.com/update/1.6.0/jinstall-6u1-windows-i586.cab"
 WIDTH = "980" HEIGHT = "495" ALIGN = "baseline">
 <PARAM NAME="cache_option" VALUE="Plugin">
 <PARAM NAME ="CODE" VALUE = "com.foo.bar.ui.MyClass" >
 <PARAM NAME="MAYSCRIPT" VALUE="true">
 <PARAM NAME ="cache_archive" VALUE = "Myjar.jar /" >
 <PARAM NAME = "type" VALUE = "application/x-java-applet;jpi-version=1.6.0">
 <PARAM NAME = "scriptable" VALUE = "false">

Create object for a class in jar file

Hi
I am using Oracle JDeveloper 10g. I have created a main application using Swing/JClient technologies. I am facing a problem for the past one week. I let u all people know my problem and I kindly request you to send a solution if known possibly confirmed.
Problem: I have created a main application using swing that class extends JFrame. This main application consists of two parts. One left side panel and one right side panel. Left side panel contains JTree component. Each item in that tree refers to a class file located in a separate jar file.i.e that acts as a separate application. If we are executing separately that jar file class, I am able to see that small application running. If I am selecting an item in JTree during runtime, I should place that small application from the respective jar file in the right side panel of the main application. I can locate the jar file and even I can create object to that particular class file. But I cannot execute the application even separately and also not able to place in the right side panel of the main application.
Note: The small application from the jar file contains one class file containing main method. That class file extends JPanel and implements JUPanel. i.e., with data binding. I am trying to create an object for this class file with data binding from my main application. Navigation bar is used in the main class file.
If possible can any provide me solution at the earliest. Waiting eagerly for the positive reply.

How can the servlet engine create objects of interfaces?help

hello,
I have this basic fundamental query...when using servlets i noticed that so many methods in the HttpServlet class take as arguments objects of the type "Interface"..where as basic principle in java is u cant instantiate interfaces...interfaces r mere templates which u implement by ur own custom classes.
For example the doGet method recieves from the servlet engine(servlet container) two arguments which r HttpServletResponse object and HttpServletRequest object..and u use these further to make use of the methods of the inmterfaces..which again is a mystery to me...why?
here is why:-
since HttpServletResponse and HttpServletRequest r interfaces..they cant be instantiated...and now that the sevlet engine provides objects of these interfaces...how come u r able to to use the methods of these interfaces...for r they not empty methods?..
example how r u able to make the sendRedirect() method of HttpServletResponse interface work...is this method not an empty method?
there r several interfaces...whose objects r being used and passed in this similar fashion....(for example there r many methods that return an enumeration...which is used as if it were an ordinary class that can be instantiated..and whose methods r non empty emthods)
please help me resolve this mystery

Don't call me "u". The word is "you". Likewise "are" and not "r".
The servlet engine creates objects of concrete classes that implement those interfaces. If you want to find the names of those classes in your particular server, you could use for examplereq.getClass().getName()

Creating object of subclass.
