Conversion of Packed Decimal Numbers to Java Data Types

Hi all,
I'm working with a mainframe file which contains datas in Packed Decimal Numbers.My requirement is to convert these datas to Java datatypes and also to convert the Java datatypes to Packed Decimal Numbers before storing them in the mainframe.
Can anyone help me out with any code for converting Java data types to/from other data formats such as: EBCDIC, IBM370 COMP (binary numbers up to 9 digits), and COMP-16 (packed decimal numbers)?
I would hugely appreciate any response to my query.
Thanking you all,
Kaushik.

Rather than go that route, I'd instead look into providing a "service" on your mainframe to:
1) provide a textual representation of the numbers (from native to text)
2) read text, converting to native numeric storage
And use that service to retrieve that information by your Java app (1)Similarly, instead of trying to write natively-formatted numbers from your Java app, I'd write it as text and make that same "service" read the text (2)
This is the kind of thing XML is for.

External SOAP client Accessing Webservice using built in Java Data type

We have built a webservice and deployed it on WLS. We accessed this from a swing
client it works fine.The webservice methods uses non-built in JAVA data types
as parameters.These are Value Objects and the JAVA Serializer and Deserializer
classes are generated using Ant task itself.The client coding uses Value objects
given by the Client_jar (generated using <Clientgen> ant task) to pass to the
webservice. We dont want to go by this way.Is there anyway were in we can pass
parameters to the method which expects non-built in java datatypes?
Why i am asking this is, i want to know how an external client (.Net client )
will be able to exceute my webservice (i.e., passing the required Object which
the method is expecting)?

Hi Anish,
Well first off, your web service doesn't send or receive "objects". It only sends
and recieves XML, which is in turn converted to/from Java objects at invocation
time. Second, a .NET (or Perl, or Python, or C++) client will be able to call
your web service, because the wsdl.exe tool (for .NET) will generate "programming
language specific" objects from the <types><schema> elements, in the WSDL of your
web service :-) The wsdl.exe tool will create C# objects from the WSDL, that will
convert XML to/from C# when your web service is called. That's the beauty of XML
schema - it's a "universal typing system", so it's not tied to a particular programming
language. The only issue is whether or not the web services platform vendor's
XML Schema/WSDL processor, can successfully process the WSDL. Some vendors have
more complete implementations of the WSDL and XML Schema specs than others, so
expect varying success here. The one in WLS 7.0 is pretty good, so you shouldn't
have too many problems consuming WSDL generated by .NET tools (or any other tool
for that matter).

Java data types are tightly coupled or loosely coupled ?

Is this another interview question? If so, the answer you should have given is, "You, sir, have been smoking too much crack."

New user for java (Data type conversion)

Hi all, I'm the newer from JAVA, just start to learn it few weeks before, there have some problem about me.
I want to konw how to change the data type ??For example, if I have a string call year and store the char "1", how can I change that field to int type ?
Thanks very much

You should have a link to, or download, the API docs. You can see them on line at:
http://java.sun.com/j2se/1.3/docs/api/index.html
Look up the class Integer. It has a static method, parseInt() which takes a String argument and returns an int.. Since it is static, you can do the following:
int value = Integer.parseInt(your_string);
Then, to make it robust, you can put try/catch around it and catch NumberFormatException if you need to do error checking.

Java Data Types?

Hi,
shall we say
The data types in Java 1.5 can be divided into 4 categories. They are:
i.     Primitive Data Types
ii.     Abstract Data Types
iii.     Arrays
iv.     Enumerated Data Types
...............?

Raijinsetsu wrote:
I have to agree with jverd...
Abstract is not a data type. Abstract declares a specific type of class which cannot be instantiated. Enumerations are just specialized objects. Arrays are also specialized objects.One could choose to consider arrays, enums, and abstract classes as separate categories.
>
If you wanted, the full list would be:
Object (reference is another term you could apply to objects)
int
long
short
byte
charEven if you include the primitives you forgot, this list is just as arbitrary as the original one, and does not correspond to the JLS.
In particular, Object is not a type. There are primitives, references, and the null type.

Not converting anything but get error: "Conversion failed converting varchar value 'X' to data type int"

I have created the following trigger that fires instead of an UPDATE statement and copies the altered data over to an Audit table before proceeding with the requested UPDATE. After doing so, I wrote a simple UPDATE statement for testing:
UPDATE Products
SET ProductCode = 'XYZ 2014', ProductName = 'Special Edition Tamborine', ListPrice = 74.99, DiscountPercent = .5
WHERE ProductID = 28;
When I run this, I get the following message:
Msg 245, Level 16, State 1, Procedure Products_UPDATE, Line 14
Conversion failed when converting the varchar value 'X' to data type int.
Here is my trigger:
IF OBJECT_ID('Products_UPDATE') IS NOT NULL
DROP TRIGGER Products_UPDATE; -- LINE 14
GO
CREATE TRIGGER Products_UPDATE
ON Products
INSTEAD OF UPDATE
AS
DECLARE @ProductID int, @CategoryID int, @ProductCode varchar, @ProductName varchar,
@Description varchar, @ListPrice money, @DiscountPercent money, @DateUpdated datetime
BEGIN
SELECT @ProductID = ProductID, @CategoryID = CategoryID, @ProductCode = ProductCode,
@ProductName = ProductName, @Description = Description, @ListPrice = ListPrice,
@DiscountPercent = DiscountPercent, @DateUpdated = GetDate()
FROM deleted;
INSERT INTO ProductsAudit
VALUES (@ProductCode, @CategoryID, @ProductCode, @ProductName, @ListPrice,
@DiscountPercent, @DateUpdated);
SELECT @ProductID = ProductID, @CategoryID = CategoryID, @ProductCode = ProductCode,
@ProductName = ProductName, @Description = Description, @ListPrice = ListPrice,
@DiscountPercent = DiscountPercent, @DateUpdated = GetDate()
FROM inserted;
UPDATE Products
SET CategoryID = @CategoryID, ProductCode = @ProductCode,
ProductName = @ProductName, Description = @Description,
ListPrice = @ListPrice, DiscountPercent = @DiscountPercent
WHERE ProductID = (SELECT ProductID FROM inserted)
END
I am confused a bit by (1) the location of the error and (2) the reason. I have looked over my defined data types and they all match.
Could someone offer a second set of eyes on the above and perhaps guide me towards a solution?
Thank you.

This is an issue in this trigger. It will work for single record updates alone. Also for your requirement you dont need a INSTEAD OF TRIGGER at all.
You just need this
IF OBJECT_ID('Products_UPDATE') IS NOT NULL
DROP TRIGGER Products_UPDATE;
GO
CREATE TRIGGER Products_UPDATE
ON Products
AFTER UPDATE
AS
BEGIN
INSERT INTO ProductsAudit
SELECT ProductID,
CategoryID,
ProductCode,
ProductName,
ListPrice,
DiscountPercent,
GetDate()
FROM deleted;
END
Now, in your original posted code there was a typo ie you repeated the column ProductCode twice
I think one should be ProductID which is why you got error due to data mismatch (ProductID is int and ProductName is varchar)
see below modified version of your original code
IF OBJECT_ID('Products_UPDATE') IS NOT NULL
DROP TRIGGER Products_UPDATE; -- LINE 14
GO
CREATE TRIGGER Products_UPDATE
ON Products
INSTEAD OF UPDATE
AS
DECLARE @ProductID int, @CategoryID int, @ProductCode varchar, @ProductName varchar,
@Description varchar, @ListPrice money, @DiscountPercent money, @DateUpdated datetime
BEGIN
SELECT @ProductID = ProductID, @CategoryID = CategoryID, @ProductCode = ProductCode,
@ProductName = ProductName, @Description = Description, @ListPrice = ListPrice,
@DiscountPercent = DiscountPercent, @DateUpdated = GetDate()
FROM deleted;
INSERT INTO ProductsAudit
VALUES (@ProductID, @CategoryID, @ProductCode, @ProductName, @ListPrice,
@DiscountPercent, @DateUpdated);
SELECT @ProductID = ProductID, @CategoryID = CategoryID, @ProductCode = ProductCode,
@ProductName = ProductName, @Description = Description, @ListPrice = ListPrice,
@DiscountPercent = DiscountPercent, @DateUpdated = GetDate()
FROM inserted;
UPDATE Products
SET CategoryID = @CategoryID, ProductCode = @ProductCode,
ProductName = @ProductName, Description = @Description,
ListPrice = @ListPrice, DiscountPercent = @DiscountPercent
WHERE ProductID = (SELECT ProductID FROM inserted)
END
I would prefer doing it as former way though

Using java date type

Hi,
Is possible to use one data type defined in java in one forms.? How do yo define this type in forms. We need insert data in one vector java(defined in java).
Thank all

for example:
javax.jcr.Session session = resourceResolver.adaptTo(Session.class);
String parentPath = "/content/blah"; // or whatever your parent path is
String nodetype = "nt:unstructured"; // or whatever other node type you require
Calendar calendar = Calendar.getInstance(); // or whatever date
Node node = session.getNode(parentPath).addNode("nodename", nodetype);
node.setProperty("myproperty", calendar);
session.save();

Java data type - byte

Hi;
I've a question here, hopefully some one can help me to clear my doubt.
private byte[] buf = new byte[1024];
as the declaration done above, does that mean the buf can hold until 1024 bytes data? as i know, byte data type only able to hold +2 power of 8 till -2 power of 7.
YY.

private byte[] buf = new byte[1024];
as the declaration done above, does that mean the buf can hold until
1024 bytes data? Yep, you've just defined an array of 1024 bytes, all neatly lined up next
to eachother, the first byte can be retrieved or altered by indexing it like
this: 'buf[0]', the next one as 'buf[1]' and the last one as 'buf[1023]'.
as i know, byte data type only able to hold +2 power of 8 till -2 power of 7.Erm, almost; a byte can store any integral number in the range -128 to 127
inclusive, i.e. -2**7 to 2**7-1.

SQL Developer may not recognise the date formats in your EXCEL so you need to tell it what it is. Check and note the value of the date column in the EXCEL file, then use the date format in the Map Source Data to Existing Table section in SQL Developer during the Import Data dialog.
For example. if the data in EXCEL is 22-JUN-09. Select the column in the above mentioned section and enter DD-MON-RR (or DD-MON-YY) in the Date Format before klicking Next to Verify. This should work perfectly.

Conversion of a binary data stream to decimal numbers

Hi
I am having great difficult working out how to convert my binary data stream to decimal numbers.
The data I am reading back is in the format of a binary string, starting with the Most Significant Bit (MSB) of the first word, then the corresponding Least Significant Bit (LSB), where a word is two bytes long. A carriage return indicates message termination. The return message starts with ‘bin,’ followed by the number of bytes requested. No delimiters are used to separate the data, but a carriage return is appended onto the end of the data.
bin,<first word msb><first word lsb>...<last word lsb><CR>
e.g. bin,$ro¬z1;@*...etc
Does anybody know of any examaple vi that can help me convert this data from binary to decimal numbers?
Many Thanks
Ash

Hi Ashley,
after getting the string you can strip the first 4 characters. After this try a typecasting to array of U16. If the numbers are not correct, you can add a swap bytes operation to the resulting array.

Problem with importing decimal numbers in Apex

Hi,
I have a ascii data file which I load into db tables calling a procedure in a db package.
Executing the procedure by SQL Plus everything works fine.
Calling the procedure by Apex button I get a "ORA-01722: invalid number; Error inserting subject" because of the decimal numbers in the data file. Taking the decimal numbers out of the file it works.
- I tried with different formats in the data file like: 4.40 4,40 4.4 4,4: Makes no difference.
- In Apex I tried column formatting in the report attribute: 999G999G999G999G990D00: Makes no difference, it's obviously only formatting the display.
- Debug mode just shows there is an error..
- The db column is of format NUMBER(10,2)
As I mentioned, with SQL Plus it works no matter of the number format in the data file.
Anybody has an idea where the problem might be?
Help is greatly appreciated,
Roger

Hi Joel,
Thanks for your reply. You were right, the NLS setting for the decimal separator in SQL*Plus is a , (komma) and in Application Express a . (point).
I suspected a NLS problem that's why I tested with different formats in the data file (4.40 4,40). Shouldn't that make a difference?
Now, to fix it: I didn't see in Apex any NLS settings, I checked in utilities and shared components. So, the way to do that is to directly write into SQL Workshop / Apex?
ALTER SESSION SET NLS_NUMERIC_CHARACTERS=",' "
Cheers,
Roger

Java rounding for Double data type

Hi,
Is there a way to change the default precision to 2 digits after decimal point for Double data type.

java.text.DecimalFormat:
import java.text.DecimalFormat;
DecimalFormat format = new DecimalFormat("#.00");
StringBuffer formatted = format.format(Math.PI, new StringBuffer(), new FieldPosition(0));
System.out.println(formatted); // prints out 3.14Probably as applicable today as it was 3 years ago

How do I return a java.sql.Timestamp data type in a Web service?

I'm new to workshop and java. I'm creating a mini application to simulate a real work Web Service (development environment is on an intranet). I was able to completely simulate the Web Services minus all date values.
I'm using a standard weblogic workshop database controls that are feeding the various WebServices and their methods (Web services was generated from DB control). I get a java type not support error when I attempt to return a java.sql.Timestamp. I temporarily got around the problem by omitting all dates from the sql.
However, we are at the point where we need the complete record.
My two questions
1) What java data type do I convert the java.sql.Timestamp to
2) Where and how do I do it in workshop.
Thanks in advance
Derrick
Source view from workshop looks something like this.
public interface MyData extends DatabaseControl, com.bea.control.ControlExtension
static public class dbOverallRec
public String key;
public String field1;
public int field2;
public java.sql.Timestamp create_date
public dbOverallRec () {};
*@jc:sq; rowset-name="OverallRowSet" statement::
*select key, field1, field2 ,create_date from overall where key={KEY}::
dbOverallRec getOverallByKey(String Key);
* I had to omit the create_date to get it to work

You should try changing java.sql.Timestamp to java.util.Calendar.
java.util.Calendar maps to the dateTime type in XML Schema, and TIMESTAMP as a JDBC type.

How to insert data type information to oracle database

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.

Data Type for File adapter

hi all,
we have a scenario which is idoc-xi-file
the output data type should be something like this:
[Data.1]
Promo,1000,,,,,,,
PromoD,2000,,yup
Item,1,IGRP,,,,,,FTY,3
Tier,1,,,,,,,ITEM,,
Itemy,1,IGRP,,,,,,FTY,1,A_,100,,ELST
we have to use file content conversion parameters for this as well as this needs to be converted to a CSV file format(third party system).
any help in declaring this kind of data type(structure) and handling file content conversion parameters would be highly appreciated.
for data type if any anybody can help me build the structure or give an example!!!
would be gr8!!!
thanks in advance
