How to implement a findbyid method in my aplicationmodule?

i have a VO named favoriteVo base on a EO favoriteEO.the key attribute is favid.
how can i get a row by id in a effecint way?
because i hava a list which include all the row's id i want to search,if there is a method can find those row by this lis,it will be better

Check out chapter '6.4.1.1 The Role of the Key Object in a View Row or Entity Row' in the Developer's Guide. FindByKey() is the method of choice.

How to implement classes and methods in badi's ?

how to implement classes and methods in badi's? and where i have to write the code based on the requirement?can anyone explain me briefly?

Hi
Every BADI by default Implements an INTERFACE which already contains some methods with parameters.
So you have to find the relavenet method based on the related paramters (by checking the fields in that paramters) you have to double click on the method and to write the code.
see the doc
DEFINING THE BADI
1) execute Tcode SE18.
2) Specify a definition Name : ZBADI_SPFLI
3) Press create
4) Choose the attribute tab. Specify short desc for badi.. and specify the type :
multiple use.
5) Choose the interface tab
6) Specify interface name: ZIF_EX_BADI_SPFLI and save.
7) Dbl clk on interface name to start class builder . specify a method name (name,
level, desc).
Method level desc
Linese;ection instance methos some desc
8) place the cursor on the method name desc its parameters to define the interface.
Parameter type refe field desc
I_carrid import spfli-carrid some
I_connid import spefi-connid some
9) save , check and activateadapter class proposed by system is
ZCL_IM_IM_LINESEL is genereated.
IMPLEMENTATION OF BADI DEFINITION
1) EXECUTE tcode se18.choose menuitem create from the implementation menubar.
2) Specify aname for implementation ZIM_LINESEL
3) Specify short desc.
4) Choose interface tab. System proposes a name fo the implementation class.
ZCL_IM_IMLINESEL which is already generarted.
5) Specify short desc for method
6) Dbl clk on method to insert code..(check the code in AAA).
7) Save , check and activate the code.

wa_spfli-cityfrom,
wa_spfli-deptime,
wa_spfli-arrtime.
hide: wa_spfli-carrid, wa_spfli-connid.
endloop.
at line-selection.
check not wa_spfli-carrid is initial.
create object exit_ref.
exit_ref1 = exit_ref.
call method exit_ref1->lineselection
EXPORTING
i_carrid = wa_spfli-carrid
i_connid = wa_spfli-connid.
clear wa_spfli.

How to implement code to method in SPROXY

HI
Version is ERP 6.0 EHP4... I have generated an webservice proxy class using Transaction SPROXY.
Now i want to implement some business logic in one of the methods of the class. But i get the message:
"You cannot edit proxy objects"
How do i add my code then?
Regards
Jakob

Hi Jakob,
Thanks for the very detailed info, this is why imperative that as much detail as possible is provided in posts. That will result in much more definitive suggestions from forum users.
You still haven't mentioned whether you've generated a consumer/client or provider service.
If it's a consumer/client service, then you won't be able to edit it. You will need to call the method of this proxy (as defined in PI)from a custom program, see guide:
[http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/c00ca32e-f991-2b10-f5be-97114bd2b08f?quicklink=index&overridelayout=true]
See the section, Abap Program to Test The Consumer Proxy specifically.
If it's a provider proxy, then the answer would change, hence I thought it could be authorization/s related.

javascript are run on the client side.. but i think what you actually mean is getting some validation to your database without submitting the form?. yes it doesn't consumes time and memory of server.. why not use ajax so you can only submit a little request.. rather than submitting the whole page..

How to implement createInstanceFromResultSet

Hi All,
I need some example to implement createInstanceFromResultSet
my requirement is to Pull a another column in query reult from another table linked using xref.
currently its doing using POST-QUERY of forms 6i.
I tried created a VO based on two EO or SQL - Query but but are taking long time as sql query itself take a long time to show result.
POST-Query
select video_seller_id into temp_video from cm_sub_seller_xref where subscriber_id = :cm_subscribers.subscriber_id and video_seller_id is not null;
if temp_video is not null then
select ext_sys_seller_reference, name into :cm_subscribers.video_seller, :cm_subscribers.video_seller_description from cm_sellers where seller_id = temp_video;
VO Query that takes time
select cm_sub_seller_xref.VIDEO_SELLER_ID, cm_sellers.EXT_SYS_SELLER_REFERENCE, cm_sellers.NAME,cm_subscribers.subscriber_id
from cm_subscribers INNER JOIN cm_sub_seller_xref on cm_sub_seller_xref.SUBSCRIBER_ID=cm_subscribers.SUBSCRIBER_ID

How can I implement a get method that lets me divide two values, Help plz

I need to implement a method that divides the values return by two other methods but I keep getting an error message, I think its divide by zero error ( I am not too sure on the exact error msg as I do not have java installed on this pc as yet), here is my example,
I have two get methods that take an int value so say
getValueOne() as method one
getValueTwo() as method two
Now I have a third method that does the following,
Public int getValueThree() {
int value =0;
value = (getValueOne() / getValueTwo())
return value;
I am not two sure on the exact code but it does something like this and I get an error. Could someone please guide me how I can successfully implement a get method that divides two values that are returned by two methods.
Thanks,
Zub

Hi, thanks for your reply. Right, how can I go about to throw an exception? I can definitely give the exact code and error message tomorrow when I can access my home pc.
And you are right there are some values that are zero! I am not very sure what throwing an exception means to be honest. Could you please give an example?
Thanks...

How to implement find methods in CMP?

As OC4J does not support EJB-QL, we need to implement the find methods by ourselves. But how? Here is my thought.
1) Still declare the find methods in EJB home, such as
public Collection findBySponsor(String sponsorGuid);
2) Do not add query part to ejb-jar.xml file;
3) In the bean class, implement the find method using JDBC code.
Does CMP allows explicit-implementation of finder methds?
Does CMP allows explicit-call to JDBC code?
Thanks,

Henry -- Why go to that trouble? For the near term I would suggest that you just modify the generated
orion-ejb-jar.xml descriptors which will include tags to allow you to either 1) enter a partial criteria or
2) enter a complete SQL statement. This is much less work and when EJB-QL is available with the product,
then you have to only add the EJB-QL to the ejb-jar.xml.
Thanks -- Jeff

How to implement Method output converion in BADI HRPAD00INFTYUI

Hi All,
I have to implement Output conversion method in HRPAD00INFTYUI for the requirement of adding custom field in the structure HRWPC_S_EP_COMMUNICATION. Usage is, In MSS general data service the manager should see his subordinates telephone extn number and his mobile number.
While trying to add, system is asking for access key and one possible solution is append structure. I am confused after seeing the parameters in that BADI. Anyone please give solution for the above requirement. Please share code as well if you have.
Thanks in Advance.
S.Vikgnesh

I am curious: can you explain WHY you want method level security? It seems woefully overkill and paranoid to me - server level security should be enough to keep out rogue code.
Anyway for that level of security, the security measures built into the JVM should be used.
[Java Security documentation|http://java.sun.com/javase/technologies/security/]
You can also look into a security API like Spring security - be warned though, it has a steep learning curve.

Can't Figure Out How To Implement IEnumerable T

I have no problem implementing IEnumerable but can't figure out how to implement IEnumerable<T>. Using the non-generic ArrayList, I have this code:
class PeopleCollection : IEnumerable
ArrayList people = new ArrayList();
public PeopleCollection() { }
public IEnumerator GetEnumerator()
return people.GetEnumerator();
class Program
static void Main(string[] args)
PeopleCollection collection = new PeopleCollection();
foreach (Person p in collection)
Console.WriteLine(p);
I'm trying to do the same thing (using a List<Person> as the member variable instead of ArrayList) but get compile errors involving improper return types on my GetEnumerator() method. I start out with this:
class PeopleCollection : IEnumerable<Person>
List<Person> myPeople = new List<Person>();
public PeopleCollection() { }
public IEnumerator<Person> GetEnumerator()
throw new NotImplementedException();
IEnumerator IEnumerable.GetEnumerator()
throw new NotImplementedException();
class Program
static void Main(string[] args)
// Create a PeopleCollection object.
PeopleCollection peopleCollection = new PeopleCollection();
// Iterate over the collection.
foreach (Person p in peopleCollection)
Console.WriteLine(p);
Console.ReadLine();
That code compiles (basically because I haven't really done anything yet), but I get compile errors when I try to implement the GetEnumerator() methods.

The List<T> class implements the IEnumerable<T> interface, so your enumerator can return the GetEnumerator call from the list.
class PeopleCollection : IEnumerable<Person>
List<Person> myPeople = new List<Person>();
public PeopleCollection() { }
public IEnumerator<Person> GetEnumerator()
return myPeople.GetEnumerator();
IEnumerator IEnumerable.GetEnumerator()
return myPeople.GetEnumerator();
class Program
static void Main(string[] args)
// Create a PeopleCollection object.
PeopleCollection peopleCollection = new PeopleCollection();
// Iterate over the collection.
foreach (Person p in peopleCollection)
Console.WriteLine(p);
Console.ReadLine();

How to implement secure Licencing for Java Apps?

Hi
I'm already thinking some months about this topic. I serached the web, some books and magazines, i asked quite a lot of people - but in the end, there seems to be no really satisfying answer.
My main question is: what can i do to protect the software i wrote? The problem is, where ever i start, i end with open questions.....
I may start delivering a custom licence key with my software that contains information i.e. about who may run it and for how long. To check integrity i sign the licences key (with a digest) and ckeck the integrity in the application. Like this, i could make sure, that the software runs only with a valid licence.
But two new problem araise - if the licence key is given to the web, everyone will be able to run the software. Second, i have to implement a methode to check the digest, so i have to deliver the key with the software and like this, the key could just be used to generate new licence files. Third, i hav to protect my code, since anyone could recompile it, he could check the algorithms i use to check the digest and even worse, he just could disable the codeblock that checks the licence.
So i use an obfuscator to scramble my code, and to get the most out of this technique, i use a controlflow obfuscator. This adds some security, but still the code can be decompiled but wouldn't be too easy to understand. For making it even a little bit harder to read, i will "distribute" the licence digest check over some different classes.
But still the first two problems remain. So i think about encrypting the licence file. To make that secure, i would use a public/private key encryption since if i use a secret key encryption i would have to deliver the key with the software and anyone could use it to generate new encrypted licene files. The problem with the public/private key is, that i should deliver a public key with the software that is only capable of decrypting, but not of encrypting. Like this, i can implement a decryption methode in the software that can decrypt the licence file and read all requiered licence data but the user is not able to generate a new licence file because he has the read-only key. Obvisouly there is no such private/public key technique that allows one key to be decrypt only and the other to be encrypt and decrypt (or at least encrypt only). Algorithms like PGP have a public key that allows encryption only and a private key that allows decryption only.
I could go on presenting some more ideas i found to "protect" software/licence but the all come to the same point where they leave a lot of other open questions.
I wonder what you all out there do to protect your software, what kind of technique you use for licencing implementation. I would be very glad to read what problem you face reagarding this topics and maybe how you solved it or what your conclusion was.
Greetings
josh

>
yes, absolutely. That's the point. Try to make it hard
to get the software some other way. So it's easer to
get the software by buying it.
Nope.
- There are those who steal it just to steal it. They don't use it.
- There are those who steal it because the price is too extreme. If your income for the year is measured as only several thousand dollars you are not going to be able to buy a package that costs a thousand dollars or more.
- There are those who steal it because the preceived benifit is less than the cost. For instance, at least in the past, MS software cost at least three times as much in some european companies compared to the exchange rate.
- Finally there are those who steal simply because they don't want to pay for it.
As far as I am concerned the last category is the only relevant one. And that is far smaller than any software theft estimates that the software industry regularly claims.

Here is an example of someone who thinks that their
work is good enough and valuable enough to stand on
its own...http://www.fileviewer.com/.
And I liked it enough that at one company I hadthem
purchase a site license. And I like it enough thatI
still remember the company five years after thelast
time I needed the product.that's fine and it would be very nice if everybody
would be like you. But that's not the case and you
even may not be sure if not someone in that company
took a copy of the software and the licence and now is
using it for free are even gave it in the "public
domain". Woulnd't that be sad if the company would
have to close down someday because just a few people
are paying for it. Even if it is such a smart
product?There was a clothing chain that closed down because they claimed that, even after installing anti-theft devices, they were still losing too much money from shop lifters.
If that is the case why do all of the other companies still exist?
If your product is good then people will buy it. The successes for that are abundant. The only success stories for copy protection schemes are for the copies that sell those schemes.

i wonder if you close your door when you leava your
appartment. I mean, what's wrong with protecting a
code? It's just the same as protecting the money you
earn, the furnish in your appartment, ...
Sorry, when I buy a product then I expect to be able to use it.
With your analogy I would have to use a code that you provided everytime I wanted to get into and out of my apartment.
So for any comments, ideas, ... on how to addsome
more protection i'm very thankfull.You search for "obfuscator".yes, as i wrote in the first posting, i know about
obfuscator, i'm using it, but it's just very poor
protection. That's why I'm looking for a smart concept
to gain a little bit more protection.And if you search for that term in these forums, and read the lengthy posts, you might find some ideas. Which is why I suggested it. (And you might understand why the alternatives are not used.)

How to implement multiple Value Helps within the same Application ??

Hi
Hint is : A row with the same key already exists it means , It is assigning the same value/Key to row and you are calling it at WDDOINIT so it giving error at the time of initialization .
Better way to do the coding at some event in view OR if not possible than just execute the first value help in wddoinit later clear all the value before gettig the other Value help. Code it at WdDoModify View to get its run time behaviour.
