Types of classes

hi,
as per me in java there is two types of class
1. Super class
2. Inner class
3. Anonymous Class
if there is more then pls write me
thanks

basically, there are two types of classes : super and nested. nested classes can furthur be categerized as inner classes and static inner classes. Anonymous classes are another useful type of classes if the code for the class is too short. rest of the details can be found on websites like google

Hi Ashley,
And yet, apparently you have a cmp-field with type char in one of your CMP entity beans. This is not supported. Please refer to the <a href="http://help.sap.com/saphelp_nw04/helpdata/en/13/dbb2b66146934a9662918755038ea1/frameset.htm">Object/Relational Mapping Rules</a> and especially to the first bullet under the table.
Hope that helps!

Link ups of movement types, valuation class & g/l A/c's

hi,
please send me the information regarding what are the link ups between the movement type valuation class & G/L A/cs
Thanks
Regards
Santosh Rothe
9421542585

Hi Santosh,
Movement types are similar to posting keys
Valuation class determines the G/L accounts to be posted automatically
Based on accounts person requirement the valuation class will be created by MM people
Integration is based on three rules
Rule 1:Valuation class is specified in material master
Rule 2:For valuation class we assign G/L Account based on the nature of transactions
Rule3:At the time of Goods receipt/Issue, the stores person enters material no, quantity& movement type
Accounts will be updated automatically based on A/C assignment to valuation class, which is specified in material master

How to know if the type of class is Enum

Hello,
I have a problem in determining the type of class whether it is an enum or not
for example
i have an enum called Gender = {Male, Female}
i have a class called Person and it has a field called gender of type Gender
when i get that field type using Java Reflection APIS, it returns a class of type Gender
i want to know if it is an enum or not?
//pseudo code
if(field.getType == Enum)
Is there a solution for that problem?

Use Class.isEnum().

Requirement types & requirement class for trading goods.

Dear all,
I am working on a project in which there are only trading goods. Majority of the items are make to order & few are make to stock.
For the make to order scenario, what will be the requirements type & requirements class to be used for the trading goods. Which item category is to be used......will it be TAN or different......
For the make to stock scenario, what will be the requirements type & requirements class to be used for the trading goods. Which item category is to be used......TAN cannot be used here as it will be used in the MTO scenario so diffferent controls.
What control parameters should I take care of while defining the requirements class & requirement type.
With best regards,
Niyaz Sayyed.

Hi,
    As my understanding, You should copy a new requirement class and make the following parameters and its values.
   For Requirements,
      req.transfer is X
      Allocation ind. is 1
      Prod.allocation is X
     No MRP is blank
For assembly
                assembly type is 2,
                 order costing is X,
                 Special stock is E,
                 order type is ZXXX
You can refer to the sap standard MTO strategy 20 to complete your project. This is the most important parts defining the requirements for sales and distribution module.

Since upgrading to new Firefox i get Error messages in Firefox and Thunderbird whenever I open a new tab: Type Error: classes (cid) is undefined or Components (cid) is undefined. How can I fix this? It shows up constantly.

This "Type Error: classes (cid) is undefined" or this "Type Error: Components (cid) is undefined keeps popping up in a small pop up box every time I open a tab or switch from Thunderbird to Firefox to open a site,

This issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
* https://support.mozilla.com/kb/Safe+Mode
* [[Troubleshooting extensions and themes]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
In Firefox 4 you can use one of these to start in [[Safe mode]]:
* Help > Restart with Add-ons Disabled
* Hold down the Shift key while double clicking the Firefox desktop shortcut (Windows)

Class type 013: class SAP_KKR_CLASS is not valid today

Dear Sir,
          At the time of production order saved one error comes i.e. Class type 013: class SAP_KKR_CLASS is not valid today.
           Thanks
           Parag

Hi ,
The error message is issued because of your customizing or
class missing in your system.
You have two options to resolve the problem depending on your business
requirement in Controlling:
1) If you required classification in controlling, you need to generate
class SAP_KKR_CLASS via OKQ3.
2) If you don't require classification in controlling, you could
deactivate 'Classification' indicator for the order type via OPJH.
More infos on this issue can be found in the mentioned note 356327.
best regards

How to get this type of class?

Hi. I'm trying to make a class like Math which i can run his methods without declaring an object.
I want this:
MyClass.method();
not this:
MyClass a = new MyClass();
a.method();
How can i do it? And what's the name of this type of classes?

I have planed to use it with a class which read a text
file like a database and return an object with the
filled fields.
Do you think i should create an instance or with
static methods is right?Without more details, I can't say for sure, but it sounds like something I would do as an instance method, rather than a class (i.e., static) method. The reason to create instances is because they hold state. The satte of an instance of your class might be the file it's responsible for or how big a buffer it has or something. Even if there's no real clear-cut state associated with what you're trying to do, I'd still use instance methods, just to get you into good habits and get practice thinking in OO terms. Resist the temptation to make everything static for now unless you have pure function-like behavior, as the Math class does.

Can we type cast class into interface?

Hello all,
Can we type cast class into interface?
If it can ,pls explain me in which suituation can we do?

You don't need to explicitly typecast a class to an interface, if the class is implementing the interface.
Example: List list = new ArrayList(); // Cast not required.And search on Google first. I'm sure this question would be answered by the lamest of tutorials.

JSP keyword type and class

<jsp:useBean id="customer" type="Auction.customer" scope="session"/>sometimes instead of type , keyword class is written..... any difference ?

hi,....thats a popular tutorial site. i know about that. ......i have no confusion about the class...........but whole confusion lies on type . is that difference written over there !! where ?
type=the type of the variable you are using to refer to the used bean.Its not clear yet.
see , we use id to refer the bean .(like in the above code) You can give anything ( of course string ) as an id.....and a bean of course has got several attributes ( or properties ) . i dont understand what exactly u mean . can u be explicit a little with an small example ?

Unknown type name 'class'; did you mean 'Class'?

I have a C++ class declaration in FTracker.h file.
class FTracker // error marks are here
When I #include/#import this header in my fooUser.mm file, it compiles. When I do #include/#import it in my fooUser.h file it doesn't, and the compiler errors are.
Unknown type name 'class'; did you mean 'Class'?
Excpected ';' after top level declarator.
I'm using XCode 6.0.1 (6A317), LLVM compiler 6.0,...
Anyone give ma a suggestion..

User defined data type generated class

Hi
When defining a new data type in the local dictionary, one has to option of generating a representation class.
I have done this and indeed received the class in my app.
However, I fail to understand how I can use this class to retrieve values set in the data type.
Thank you for your assistance

Hello Y PEERY
I am not clear which context you are talking about .
Are you taking about simple type inside local dictonary ?
or
A project with data dictonary type ?
(for webdynpro only)
In both the case no need to deal with internal generated class, this is somethig which is requrired to framework itself , end developer not at all using /modifiying it.
or
Might you are dealing with EJB so in this case representation class is generated once we provide the basic(name , package etc) to it , further you can modify it according to your use.
Please clarify

++Custom Serialization with Complex Data type (Nested Classes)

Hi,
We have a scenario wherein we need to write CUSTOM SERIALIZERS for complex datatypes like INVOICE & ORDER (INVOICE inturn has ADDRESS type among others, ORDER has ADDRESS type, a COLLECTION of type ORDERITEM each of which are Java Classes in themselves)
The example of Custom Serializer given in the SOA AS Dev Guide http://download.oracle.com/docs/cd/B31017_01/web.1013/b28975/custserial.htm#CFHHIBCA)
shows only a simple java type used for serialization and deserialization.
Can anyone please help us out by sharing any example depicting the CUSTOM SERIALIZERs for COMPLEX DATA TYPES?
Thanks in advance,
Pavan.

Hello,
Could you please post the code of your classes in the forum (at least the interfaces) ?

Message Mapping of type ABAP Class not being shown

Hi all,
I have been trying to follow the given blog:
/people/ravikumar.allampallam/blog/2005/02/10/different-types-of-mapping-in-xi
Even after doing the changes mentioned in the blog, i do not see the ABAP Class in the list of Message Mapping types.
Do i need to do anyother configuration. Pls guide.
Regards
Neetu

Hi Neetu,
You will have to enable your ABAP mapping first.
Do the following steps, pay carefull attention to the values you enter,
In
IntegrationBuilder ->IntegrationBuilder.Repository -> com.sap.aii.repository.mapping.additionaltypes
enter the value of
R3_ABAP|Abapclass;R3_XSLT|XSL (ABAP Engine)
If the above doesnt work, try Abap-class instead of Abapclass in the above line.
And then follow the remaining steps, make sure that the above value is correct. Your ABAP mapping should appear in your Integration Repository.'
I suggest you go through these links:
https://websmp101.sap-ag.de/~sapdownload/011000358700003082332004E/HowToABAPMapping.pdf
/people/ravikumar.allampallam/blog/2005/02/10/different-types-of-mapping-in-xi
ABAP Mapping Vs Java Mapping.
Refer to following SDN Demo which explains the need and how to do the ABAP mapping.
