Declaring and using a "collections" object?

Hi,
-I want to declare a Collections object like so...
ArrayList arr = new ArrayList;
Collections colls = new Collections;
-so i can use the shuffle() command on an ArrayList
e.g. colls.shuffle(arr);
-The problem is i get a compiler error like this:
"Collections() has private access in Java.utils.Collections"
-How do i get around this???

So all i have to do is:
Collections colls;
ArrayList arr = new ArrayList;
colls.shuffle(arr);
Is this correct?
Thanks,
PJ

Best way to declare and use internal table

Hi all,
As per my knoledge there are various techeniques (Methods) to declare and use the internal tables.
Please Suggest me the Best way to declaring and using internal table ( WITH EXAMPLE ).
Please Give the reason as well how the particular method is good ?
What are benefits of particular method ?
Thanks in advance.
Regards
Raj

Hello Raj Ahir,
There are so many methods to declare an internal table.
Mainly I would like to explain 2 of them mostly used.
1. Using Work Area and
2. With header line.
This with header line concept is not suggestable, because, when we shift the code to oops concept.. it doesn't work... Because OOPS doesn't support the Headerline concept...
But it all depends on the situation.
If you are sure that your program doen't make use of the OOPs concept, you can use HEADER LINE concept. If it invols OOPs use WORK AREA concept.
Now I'l explain these two methods with an example each...
1. Using Work area.
TABLES: sflight.
DATA: it_sflight TYPE TABLE OF sflight.
DATA: wa_sflight LIKE LINE OF it_sflight.
SELECT *
FROM sflight
INTO it_sflight
WHERE <condition>.
LOOP AT it_sflight INTO wa_sflight.
    WRITE / wa_sflight.
ENDLOOP.
In this case we have to transfer data into work area wa_sflight.
We can't access the data from the internal table direclty without work
area.
*<===============================================
2. Using Header line.
DATA: BEGIN OF it_sflight OCCURS 0,
          carrid LIKE sflight-carrid,
          connid LIKE sflight-connid,
          fldate LIKE sflight-fldate,
        END OF it_sflight.
SELECT *
    FROM sflight
    INTO it_sflight
    WHERE <condition>.
    LOOP AT it_sflight INTO wa_sflight.
      WRITE / wa_sflight.
    ENDLOOP.
In this case we can directly access the data from the internal table.
Here the internal table name represents the header. for each and every
interation the header line will get filled with new data. If you want to
represnent the internal table body you can use it_sflight[].
*<======================================================
TYPES: BEGIN OF st_sflight,
         carrid LIKE sflight-carrid,
         connid LIKE sflight-connid,
         fldate LIKE sflight-fldate,
       END OF st_sflight.
DATA: it_sflight TYPE TABLE OF st_sflight,
      wa_sflight LIKE LINE OF it_sflight.
This is using with work area.
DATA: it_sflight LIKE sflight OCCURS 0 WITH HEADER LINE.
This is using header line.

Problem declaring and using a REF CURSOR

I'm having a real problem using a REF CURSOR type
Here's the DECLARE and the start of the BEGIN I've so far developed.
DECLARE
TYPE r1 IS RECORD (
szvcapc_pidm szvcapc.szvcapc_pidm%TYPE,
szvcapc_term_code szvcapc.szvcapc_term_code%TYPE,
szvcapc_request_no szvcapc.szvcapc_request_no%TYPE);
szvcapc_rec r1;
TYPE cursor_1 IS REF CURSOR RETURN r1;
szvcapc_cv cursor_1;
TYPE r2 IS RECORD (
stvests_code stvests.stvests_code%TYPE
stvests_rec r2;
TYPE cursor_2 IS REF CURSOR RETURN stvests_rec;
stvests_cv cursor_2;
BEGIN
OPEN szvcapc_cv FOR
SELECT szvcapc_pidm, szvcapc_term_code, szvcapc_request_no
FROM szvcapc
WHERE szvcapc_passed_ind = 'Y'
AND szvcapc_award_credits = 'N';
LOOP
FETCH szvcapc_cv INTO szvcapc_rec;
EXIT WHEN szvcapc_cv%NOTFOUND;
END LOOP;
OPEN stvests_cv FOR
SELECT stvests_code
FROM stvests
WHERE stvests_eff_headcount = 'Y';
LOOP
FETCH stvests_cv INTO stvests_rec;
EXIT WHEN stvests_cv%NOTFOUND;
END LOOP;
SELECT *
FROM (
<snip>
INNER JOIN stvests_rec
ON SFBETRM.SFBETRM_ESTS_CODE = stvests_rec.STVESTS_CODE
<snip>
I later try to use the stvests_rec and szvcapc_rec in the main SELECT statement it doesn't recognise stvests_rec and szvcapc_rec as a "Table or View".
I have to use a REF CURSOR as this code is ultimately for use in Oracle Reports.
What am I doing wrong?

> The reason I'm trying to use a REF CURSOR is that I was told that you
couldn't use CURSORs in Oracle Reports.
That does not change anything ito what happens on the Oracle server side. A cursor is a cursor is a cursor.
Every single SQL winds up as a cursor. Each cursor has a reference handle to access and use. HOW this handle is used in the language differs. But that is a language issue and not an Oracle RDBMS issue.
For example. An EXECUTE IMMEDIATE in PL/SQL creates a cursor handle and destroys it after use - automatically. An implicit cursor works the same. An explicit cursor you have the handle fetch from it and close from it when done.
A ref cursor is simply a handle that can be returned to an external client - allowing that application to use the handle to fetch the rows.
Do not think that a ref cursor is any different from the RDBMS side than any other cursor. The RDBMS does not know the difference. Does not care and nor should it.
> I'm trying to reduce the hits on the database from nested selects by
removing the dataset from the main SELECT statement and performing it only
once outside and then referencing this previously collected dataset inside the
main SELECT statement.
Good stuff that you are considering SQL performance. But you need to make sure that you
a) identify the performance inhibitor issue correctly
b) address this issue correctly
And you need to do that within SQL. Not PL/SQL. PL/SQL will always be slower at crunching data than SQL. For example, wanting to cache the data somehow to reduce the read overhead - that is exactly what the DB buffer cache does. It caches data. That is also exactly what the CBO will attempt - reduce the amount of data that needs to be read and processed.
Not saying that the RDBMS can do it all. It needs help from you - in the form of a SQL that instructs it to process only the minimum amount of data required to get the required results. In the form of a sound physical design that provides optimal usage of data storage and access (like indexing, partitioning, clustering, etc).
Bottom line - you cannot use a REF CURSOR to make a SQL go faster. A REF CURSOR is simply a cursor in the SQL Engine. A cursor is nothing but the "compiled-and-executable" code of a SQL "source program".

Need Ideas for creating and using Custom Business Object

Hello Guys,
I am developing an application which uses a Request->Approve->Create approach for creating Purchase documents.
Now I am a little puzzled about how to make use of the Business Object BUS2014.
The application I am developing has its own unique 'Request Number' (say REQID) which will point to the Request for Creation of a purchase order.
Whenever a Request is created (from a Z-Tcode) a workflow needs to be initiated and it has to be sent to the approver.
The Purchase Document will be created once the approver approves.
Now my confusion here is, if I use BUS2014, the object will be instantiated only during the final step of the workflow. But I need an instance during the beginning of the Requestor ->Approver negotiations as I am playing with events. These events needs an Object_key.
How should I proceed here?
Should I create a new logical Business Object like ZPOREQ where I have the above mentioned REQID as the key?
And should I have an attribute of type BUS2014 inside the custom BO?
How will I make use of the methods like BUS2014.Create etc which I may need to create the purchase document?
Any small direction will be a huge help for me to get used to this wilderness.

Hi,
You should continue with the ABAP class idea. The business objects are kind of "obsolete" already, and if there is a need to create a new "object", ABAP classes are the way to go. Business objects are still useful, but I normally use them only when an existing standard business object fulfills the requirements (possibly with slight additions) which is almost never.
From my point of view you can use the existing class. Depending on the circumstances I normally have just one class that I use for both workflow and the possible other functionality that is required, but you have to understand that I have this goal in my mind already when starting the development process. As your class most probably has many useful features already (such as you have the header and item data as attributes etc. (if I understood correctly?), these are also useful in in workflow (class attributes will be available in WF container etc.).
If you are hesitant to use the same class directly in your workflow, you could also create a new class ZCL_REQUEST_FOR_WF (with the workflow interface), and then simply add your existing class ZCL_WF_REQUEST as an attribute to this new class. Then this new workflow class could include the pure workflow stuff, and your existing class the non-workflow stuff. But this most probably will not make much sense - just implement the if_workflow interface in your existing class (this is just one possibility that you might consider.)

How to declare and use a variable in BI Publisher report

Hi Experts ,
I have to groups of serial numbers and both group are put in same table and same row one after another , and i have a condition that if no serial number is present in both group than the line of that table should not be appeared ,i used the condition region ,biut this condition region is working in single group case if i put both groups together ,the blaing line appears with its label ,I think if i will have have variable which can count the total present of serial number than I cant put a single condition ,would you please help me ,how can I declare a variable and how can i count the number of serials in both groups ,please find below the example
<grp1><?SR_NUM1?><end of grp1> <grp2><?SR_NUM2?><end of grp2>
above example is how i am printing now ,now i need a combined condition where if bot group do not contain any value then this blank line should not appear . thanks in advance.
Thanks

Hi ,
Decalring the Varible :
<?xdoxslt:set_variable($_XDOCTX, 'var', 0)?>
Do the calculation :
<?xdoxslt:set_variable($_XDOCTX,'var', xdoxslt:get_variable($_XDOCTX,'var‘)+ XML columnname)?>
Display the Variable :
<?xdoxslt:get_variable($_XDOCTX, 'var')?>
Declare the varaible before your loop starts.Do the calculation part inside the loop so for each row it will be updated.
Display the results where you want using the form field and place the display varaible syntax.
Hope this will helpful for you.
Thanks,

How to use VBA to View PDF file and use an OCR object?

As subject, I need to use VBA to open PDFs via Acrobat. Convert images to texts. And get some key words from the documents.
But I cannot find the API for VBA from SDK.

The API for VB is part of the "Interapplication Communication" section, specifically the part for "OLE". You can also use much of the JavaScript API through a VB:JavaScript linkage.
I don't know if there is an API to running OCR.

Where do I use These lock object FM's (Enqueue & D? and How do I use them?

I created lock object for user defined table (zconsist). The system automatically created 2 FM's (Enquiue & Dequeue).
I created a new TCode and accessing this with mulitple users to do some updates and inserts in that above table.
I used INSERT ZCONSIST statement in 5 places in my program (4 include programs).
Where do I use These FM's? and How do I use them?
I mean before inserting which FM I need to use? after immediately what fm used?.
every insert statemnt before i need to use the respective fm? so 5 places i need to call the respective FM is it right?
thank in advance.

Hi Sekhar,
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
check this link for example.
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
tables:vbak.
call function 'ENQUEUE_EZLOCK3'
exporting
mode_vbak = 'E'
mandt = sy-mandt
vbeln = vbak-vbeln
X_VBELN = ' '
_SCOPE = '2'
_WAIT = ' '
_COLLECT = ' '
EXCEPTIONS
FOREIGN_LOCK = 1
SYSTEM_FAILURE = 2
OTHERS = 3
if sy-subrc 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
endif.
Normally ABAPers will create the Lock objects, because we know when to lock and how to lock and where to lock the Object then after completing our updations we unlock the Objects in the Tables
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
purpose: If multiple user try to access a database object, inconsistency may occer. To avoid that inconsistency and to let multiple user give the accessibility of the database objects the locking mechanism is used.
Steps: first we create a loc object in se11 . Suppose for a table mara. It will create two functional module.:
1. enque_lockobject
1. deque_lockobject
before updating any table first we lock the table by calling enque_lockobject fm and then after updating we release the lock by deque_lockobject.
http://help.sap.com/saphelp_nw04/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
GO TO SE11
Select the radio button "Lock object"..
Give the name starts with EZ or EY..
Example: EYTEST
Press Create button..
Give the short description..
Example: Lock object for table ZTABLE..
In the tables tab..Give the table name..
Example: ZTABLE
Save and generate..
Your lock object is now created..You can see the LOCK MODULES..
In the menu ..GOTO -> LOCK MODULES..There you can see the ENQUEUE and DEQUEUE function

No object can select when collecting objects for transport

Hi.Experts:
When I use RSA1 and want to collect objects for transport,I found that no objects can be found for some object type,such as ISTD/TRFN etc, any body who know this situation?
Best Regards
Martin Xie

Hi Martin,
best way to collect objects into transport request is throught RSA1 -> Transport connection.
in Transport connection, you have different options to collect objects into transport request.
In data flow before...
here you can see objects that are already have transport request, package...

Using a script object

Hi,
I have beginner skills using LC Designer ES and am trying to insert and use a script object. I found a JavaScript function online: http://home.online.no/~pjacklam/notes/invnorm/impl/misra/normsinv.html and am trying to get it to do some math calculations in a Designer form.
I've uploaded a sample test form at: http://elearningprojects.com/TestFormula1.pdf
Can't get it to work.Trying to run the JS formula in the script object (by clicking on a button), using a few hard-coded variables, and display the results (Dprime1 and Dprime2) in 2 text fields.
I would much appreciate if someone can take a look and suggest how to get it working correctly.
Thanks for your help.
Kind Regards,
saratogacoach

Hi Paul,
Thank you for your reply and suggestions. With beginner skills in LC Designer (I'm a retired social worker), I am not sure how to do this.
Is my identifying the script object path correct?
form1.#subform[0].#variables[0].SO1.function_name(NORMSINV(p));
When you say "You are calling this function a few times in your code so you will have to modify each call." I am not sure how to change this.
I currently have (note that I added the SO1. to the function calls):
var p = totalscore5
var probit1 = SO1.NORMSINV(p)
var p = totalscore6
var probit2 = SO1.NORMSINV(p)
var Dprime1 = probit1-probit2
var p = totalscore8
var probit3 = SO1.NORMSINV(p)
var p = totalscore7
var probit4 = SO1.NORMSINV(p)
var Dprime2 = probit3-probit4
Can you specify what a modified script would look like? I'm stuck.
Also, have I set up displaying the Dprime1 variable's value in the TextField1 correctly?
Thanks very much for your help.

CAML Query to get specific item in folder based on dropdown value using Javascript client object model

Hi,
I am using the Javascript Client object model.
I have a custom list and a custom document library.
Custom list contains 2 columns - dlName , dlValue
The document library contains 2 folders - "folder1" , "folder2" and contains some images.
The image name starts with the "dlValue" available in the custom list
I am using a visual webpart and using javascript client object model.
I am trying to achieve the below functionality:
1) Load a dropdown with the custom list.
2) set the image based on the value in dropdown.
I have achieved the first option, I have set the dropdown, but not sure how to query the folder and set the image.
Below is the code i have used so far:
//In Visual webpart
<select id="ddlTest" >
</select>
<br/>
<div id="PreviewLayer">
<img id="imgPlaceHolder" runat="server" alt="Image" title="imgPlaceHolder" src=" " />
</div>
// In Javascript file
function RenderHtmlOnSuccess() {
var ddlTest = this.document.getElementById("ddlTest");
ddlTest.options.length = 0;
var enumerator = this.customListItems.getEnumerator();
while (enumerator.moveNext()) {
var currentItem = enumerator.get_current();
var dropdownValue = currentItem.get_item("dlValue");
ddlTest.options[ddlTest.options.length] = new Option(currentItem.get_item("dlName"), dropdownValue);
setImage(dropdownValue); // Not sure how to query the folder and set the image based on value.
// Also if dropdown value is changed, corresponding image should be shown
How to query the folder and based on dropdown value, show the image? Also, how to handle the dropdown value change?
Thanks

Query on using Collection object in Multithreading

All,
I have a query on multithreading, I have a collection object-eg. HashMap which needs to be shared
among threads, I my have 3 options
1st option is to synchronize the method which does some manipulation on the collection object,
2nd option is to hold a lock on that object like
synchronized(object){
//do some work
3rd option - to make use of class ConcurrentHashMap available in java.util.concurrent package; which claims to be
Thread safe but also says the following in the API - They do not throw ConcurrentModificationException. However,
iterators are designed to be used by only one thread at a time
My queston is - how do I choose between these 3?
I know the decison needs to be taken by keeping performance issue in mind and also the number of times the values in HashMap will be updated by the threads. Can some one explain to me when/under what circumstances do I use options 1 || 2 || 3

My application has actually gone live now - after doing some load/performance testing
and comming to the conclusion that performance is satisfactory [I am designing a SMS gateway
that receives/buffers/stores/sends SMS]
Initially I used Hashmap and a LinkedList to store objects in memory and I had a mixture
of places where some times I made the entire method that modifies the LinkedList & hashmap
synchronized and some places where I held a lock on the object alone (I wasnt too sure which to use where)
Then upon movin to 1.5 I rechanged the the data structure to use ConcurrentLinkedQueue & ConcurrenthashMap.
But i have places where I still hold synchronized locks over those objects (which i think is unnecessary and removing the locks may improve the performance)
So can i come to the conclusion that classes in java.util.concurrent are all threadsafe and we can stop holding locks on the objects and let java take care of itself [or should I still hold a lock when doing structural modification] [though the APi states that a oncurrentmodificationexception will not be thrown & iterators are designed to be used by only one thread at a time]

Declaring and using a "collections" object?
