Date Picker Incorrect time! URGENT HELP NEEDED

Hello
We have an application. In the application when you click a date picker the time is an hour forward. Where does the date picker get its time from?
We have alot of date pickers and we are not wanting to set them by a query.
The OS the machine application server is on is the correct time.
Even if I create an item and select sysdate from dual the time is correct.
Please help.

From the SQL Reference manual:
"The difference between this function and LOCALTIMESTAMP is that CURRENT_TIMESTAMP returns a TIMESTAMP WITH TIME ZONE value while LOCALTIMESTAMP returns a TIMESTAMP value."
In your query, you're chopping off the timezone of CURRENT_TIMESTAMP (as it's of data type TIMESTAMP WITH TIME ZONE).
Perform these two queries in SQL Commands:
select current_timstamp from dual;
select localtimestamp from dual;I'll bet you a million dollars that the query against LOCALTIMESTAMP is off by one hour from what you expect.

Validation on Integer data type attribute

Hi,
Working on jdev 11.1.1.3.0
I have to do validation on integer data type like, it should not allow 13.20(only single digit numbers.).
I am doing validation on AMImpl and converting the int into string
String per=Row.getPer().toString();// here if user enter 13.20, then per containing only 13 so its not going to inside if.
if(StringUtils.contains(per,"."))
return false;
Even i have written regular expression on my field but its working
can any one help me.

Difference Between Data Type and Data Object

Difference Between Data Type and Data Object

hi magesh
Data types can be divided into
elementary,
reference, and
complex types.
Elementary Types
Elementary types are the smallest indivisible unit of types. They can be grouped as those with fixed length and those with variable length.
Fixed-Length Elementary Types
There are eight predefined types in ABAP with fixed length:
Four character types:
Character (C),
Numeric character (N),
Date (D),
and Time (T).
One hexadecimal type:
Byte field (X).
Three numeric types:
Integer (I),
Floating-point number (F)
and Packed number (P).
Variable-Length Elementary Types
There are two predefined types in ABAP with variable length:
STRING for character strings
XSTRING for byte strings
Reference Types
Reference types
describe data objects that contain references (pointers) to other objects (data objects and objects in ABAP Objects).
Data Types
1) As well as occurring as attributes of a data object, data types can also be defined independently.
2)You can then use them later on in conjunction with a data object.
3) The definition of a user-defined data type is based on a set of predefined elementary data types.
4) You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary.
5) You can use your own data types to declare data objects or to check the types of parameters in generic operations.
Data Objects
1)Data objects are the physical units with which ABAP statements work at runtime.
2) The contents of a data object occupy memory space in the program.
3) ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type..
4) For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
5) Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type).
6) You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures).
7) As well as fields in the memory area of the program, the program also treats literals like data objects.

Differences between DATA TYPE and DATA OBJECTS

I am new to ABAP,I want to know the differences between DATA TYPE and DATA OBJECTS with some examples.
please help me regarding this.

Hi Ashish,
Data Types:       Are pure descriptions.
               No memory is associated with data types.
               Describes the technical properties of data objects.
EX.
1.     C-CHARACTER
2.     D-DATE
3.     F-FLOAT
4.     I-INTEGER
5.     N-NUMERIC TEXT
6.     T-TIME
7.     P-PACKED NUMBER
8.     X-HEXADECIMAL
9.     STRING-Variable length string.
10.     XSTRING-Variable length byte string.
Data Objects: Are created during runtime.
                They cannot exist without the data Types.
                Occupies memory space.
EX:
1.     INTERNAL DATA OBJECT- Internal Data objects
     LITEERAL- A literal has a fixed value.Ex: WRITE:u201DWORK HARDu201D.
     VARIABLES: Data statement is used to create variables.
EX.DATA: NUM TYPE I.
NUM: VARIABLE defined by data statement.
EX: DATA: PRICE LIKE NUM.
     CONSTANT-It is a data object, which contains a constant value throughout the program.
Can be declared in program by using CONSTANT statement.
EX:CONSTANT: INT TYPE I VALUE 15.
2.     EXTERNAL DATA OBJECT: Are defined in tables i.e In ABAP/4 dictionary you can access this data from table.
         EX: TABLES: SFLIGHT
          DATA: SEATS LIKE SFLIGHT-SEATSMAX.
3.     SYSTEM DEFINED DATA OBJECTS:Space & system variables like SY-UNAME,SY-DATUM, SY-REPID.
4.     SPECIAL DATA OBJECTS:
     PARAMETERS: Are Variables ,which can accept value from user.
      SELECTION SCREEN : Are special internal tables to accept value ranges from user.
3 APPROACHES TO DEFINE DATA OBJECTS.
1.     ELEMENTARY TYPES
DATA: Customer _Name (25) TYPE C,
               Vendor_Name (25) TYPE C.
2.     REFRENCE TO AN EXISTING FIELD:
DATA: Customer _Name2 (25) TYPE C,
              Vendor_Name2 (25) LIKE Customer_Name2
3.     REFRENCE TO NON-ELEMENTARY TYPE:
TYPES: T_NAME (25) TYPE C
DATA: CUSTOMER_NAME TYPE T_NAME
               VENDOR_NAME TYPE T_NAME
4.     RECORD-Information in rows & columns.
DATA: BEGIN OF BOOKING,
                                ID (4) TYPE C,
                                FLIGHT_DATE TYPE D,
                                NAME LIKE CUSTOMER_NAME,
                                END OF BOOKING.
You can also look into SAP help for more information.

XI settings, change of Data Types and XI still maps old structures

Hi,
I have defined XI scenario, where synchronous WebService is being called, and XI calls RFC function module, which returns data. It was working perfectly, until
I have changed the order of few fields in Data Type and added a few new (exactly as the changes in RFC function module).
And now the WebService returns exception, on the first field added to the interface:
<Trace level="1" type="T">com.sap.aii.utilxi.misc.api.BaseRuntimeException: RuntimeException in Message-Mapping transformation: Cannot produce target element /ns1:MT_BMS_Response/CUSTOMERS_PERSON/TITLE. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd at
TITLE is added field.
I have reactivated everything one by one again, clear cache from Integration Builder and Integration Directory, but it does not help and still old structures are being used in XI.
I have tested the Interface Mapping and all fields are transformed correctly.
Please help as it comes a little urgent and I have run out of ideas what to do to refresh the customizing of data types?
Thank you in advance!

Hi Peter,
Yes, I am calling RFC function module from XI.
After I changed the interface of RFC in SAP, I have imported this RFC once more to XI in Integration Builder and new structures appeared.
And exception returned is that first new field added to the RFC and Data Type and so on, returns an exception.
And returned XML structures (in message monitoring) appears to be still old structures.

Last 6 months of data based on date feild that is an integer data type

Hi Folks
I have a date column called 'YYYYMM' that is an Integer data type in YYYYMM format (eg. 201309). I want to return records from the last 6 months.
If the column was in a date format I could use something like
[YYYYMM] >DATEADD(M, -6, CURRENT_TIMESTAMP)
Therefore I assume I need to do a CONVERSION of INT into a date format with something like
CONVERT (DATE, [YYYYMM]
But I get the message "Explicit conversion from data type int to date is not allowed"
Can someone suggested a work around?
Many thanks Steve

another way is this
SELECT *
FROM Table
WHERE DATEADD(mm,(dateintfield%100)-1,DATEADD(yy,(dateintfield/100) -1900,0)) >=DATEADD(mm,DATEDIFF(mm,0,GETDATE())-6,0)AND DATEADD(mm,(dateintfield%100)-1,DATEADD(yy,(dateintfield/100) -1900,0)) < DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0)
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

How to insert data type information to oracle database

Hi, there,
I want to insert date information to oracle database in a jsp page using JSTL. but always got wrong message:
javax.servlet.jsp.JspException:

I don't know how to convert java date type to oracle date type or vice versa. the following is the source code(all the fields of DATE_DEFAULT,DATE_SHORT,DATE_MEDIUM are oracle date type. and even I want to insert d instead d1, I got the same wrong message)

</sql:update>
</body>
</html>
thank you very much for the great help!!

I don't have time to read thru all your code, but I hope this information will help you.
It depends on how the Oracle database was set up. Usually, the date format is something like this: '27-MAY-2003 22:10:00'. A quick check will be to run this SQL script in SQLPlus:
select sysdate from dual;
You have to convert the date from textbox or whatever to this exact Oracle format. Otherwise, Oracle will not accept it. It is very picky on that. I found the best way is to do the conversion inside the SQL statement. It makes life so much easier.
Hope this helps.

Difference Between Data type and message type

Hi,
    i have doubt on data type and message type.why we are mapping the message type why not data type?wht is the difference between data type and message type?

Hi Narayanana,
Data type defines the structure of your xml message.Message type is the wrapper of data type.You will be using your message type while mapping and not the data type.Its the abstraction concept used in oops

Hi Suresh,
Data Type defines the structure of the message and it will be wrapped under Message Type.
Hope the details below will clearify your doubts.
A data type in a programming language is a set of data with values having predefined characteristics. Examples of data types are: integer, floating point unit number, character, string, and pointer.
The characteristic of columns and variables that defines what types of data values they can store.
Check out the details:
http://en.wikipedia.org/wiki/Data_type
A message type comprises a data type that describes the structure of a message. At the following points in SAP Exchange Infrastructure you can refer to the message to be exchanged at runtime by using the message type:

URGENT HELP NEEDED ... Tomcat Realm and JRE1.4 plug-in problem

I have tried the Security Realm of Tomcat. Since I do not have
an LDAP server, I decided to use the Tomcat-users.xml file in
Tomcat\conf directory.
I added the following lines of code in the web.xml file.
<security-constraint>
<web-resource-collection>
<web-resource-name>Entire Application</web-resource-name>
<url-pattern>/*</url-pattern>
</web-resource-collection>
<auth-constraint>

<role-name>webviewer</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>BASIC</auth-method>
<realm-name>Tomcat Manager Application</realm-name>
</login-config>
The <role-name> "webviewer" is added into "Tomcat-Users.xml" as the following:
<tomcat-users>
<user name="test" password="password" roles="webviewer" />
</tomcat-users>
So, now when we type the url: http://localhost:8080/adbpdbre/default.htm, TOMCAT shows a dialog box asking for UserName: and Password:Now, only when we give the username and password, it shows the page. This is exactly what we want.
But the problem now is, this default.htm page, has 5 links to 5 applets. The first time that I click on one of these links, the JRE plug of 1.4 shows a dialog again asking for the username and password. Till I dont provide the username and password the system doesnt go ahead and applet doesnt load. I do not want the JRE to ask me for the username/passwords again..How to avoid this ?
Can you give me some more information on this. Ultimately in the production usage, we will be using LDAP and not Tomcat's memory realm.
URGENT HELP NEEDED ... I need to get back to my client on this.
Help would be v. much appreciated.

In the config file, you 're essentially saying that you want Tomcat to prompt for usr/passw on every request (url-pattern = /*) made by a 'webviewer', and that's exactly what Tomcat is doing.
Consider using specific url-patterns & roles for resources to be protected. If for now, all you need is to protect the first page, use a more specific url-pattern.
Just an advice : if you'll be using LDAP in production, do not waste time with Tomcat's Security Realm and the BASIC authentication type, since the two have not much in common. Start reading doc on LDAP, and code a prototype, or even better, a vertical slice of the app (i.e a proof of concept).

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object

(Data Structures) Position (in Lists) ...simple - Urgent help needed!!!

I know that Position is the abstract data type and that it supports only one method - element() (that returns the element stored in this position).. Now when I wish to implement a List (with doubly linked list) using the Interface List...In the Interface List there are quite few methods to implement , however, few of them require Position parameter...And this is where I am getting confused..What is the Position parameter? A number? or? Here is a sample code
//Node class for implementing a Doubly linked list
Class DoublyNode implements Position
{ public DoublyNode prev, next;
public Object element
//constructor
public Dnode()
{ prev = null
next = null
element = null
public Object element(){
return element;
Class NodeList implements List{
// bunch of methods and variables
public Position before(Position p) // What is Position parameter? a position number? or what?
{ DoublyNode v = (DoublyNode)p;
DoublyNode prev = v.prev;
return prev;
Now I know since DoublyNode implements Position, we can cast a position to a node, but what is that Position parameter? Can anybody explain this minor detail to me? Or how do these Position parameters work in programing? All I know is, given a position parameter (what ?) the Doubly linked list will instantly locate the appropriate node (how) and you can cast it to a node and return the node...but how does this Position work?
I am aware of the fact that everytime you insert in the list , that inserted element gets a position (a number?) how do I refer/catch back that node ? Via position (number)?
Please Help....
I appreciate it a lot!!!

There's no standard Java class called Position, at least none that has anything to do with lists or collections. So this must be a class or interface that somebody else wrote. At any rate, a Position parameter needs a Position object, obvious as that may sound. How do you create a Position object? Somebody with documentation of the Position class or interface might be able to help here -- is this homework?
