oracle.jbo.domain.Number, round() method to change the type of data returned?
Hi all
When I tried to round the value to oracle.jbo.domain.Number, it returns data of type oracle.sql.Number. Please see the following code snippet:
Number unitPrice = new Number (9.95);
Number of numOfRet = new Number (5);
Total = (unitPrice.multiply (numOfRet)) .multiply (1.05) .round (2);
The third line can not compile because the round() method returns a data type of oracle.sql.Number, which generates the compile error. If I put a guy up there, it works. When I checked the javadoc, the method has a number of return type. But it says in the details of the description of the method, it returns a Java int. Can I ask is there something wrong here? You can find the javadoc here: number (Oracle ADF business components API Reference 10.1.2 areas)
Thank you
Sheet
Order to understand, the problem is that the round() method returns a number, but a NUMBER data type.
NUMBER public tour (int decimal_place)
Therefore, cast to the number.

the message is true. Oracle Jbo.domain.Number cannot be cast to the number of Java. Make sure that your cast the object to
oracle.jbo.domain.Number
(just to change the import statement at the top of your Java class)

I'm trying to implement sequences and followed the following ADF essentials to create the same. For some strange reason, I meet, it throws the error of compilation as below.

Please help me!
Thank youHello
What Type of Map you selected when creating components trade?
Make sure it is Oracle. Looks like you have selected the Type of card Java takes DepartmentId column as Integer.
It takes so you must import the oracle.jbo.domain.Number class
setDepartmentId (numeric value)
Recommendation: Create business components again with card Type Oracle.

"" Type = "java.math.BigDecimal type =" Oracle.jbo.domain.Number "VS".
Hi all! I need some explanation about types: Type = "oracle.jbo.domain.Number"VS Type = "java.math.BigDecimal"
I have variable enableEditing:
If attribute EO TaksacijasPk is with the type "oracle.jbo.domain.Number" then all work with above the line, but if this attribute is of type "Java.Math.BigDecimal" then code above line do not work. To fix it, I need to add toString() operation in the line of code:this.enableEditing = this.getSelectedTaks().getAttribute("TaksacijasPk").equals(taksId);
Maybe the question is, why in one case, I have to add toString() operation and in others not?this.enableEditing = this.getSelectedTaks().getAttribute("TaksacijasPk").toString().equals(taksId);
Best regards, Debuger!Javadoc for the BigDecimal said
Unlike compareTo, this method takes two objects BigDecimal equal only if they are equal in value and scale (so 2.0 is not equal to 2.00 compared to this method).
You try to compare a BigDecimal/number for a taskId (which we don't have no idea what class it is).
Suppose that taskId is a string.
. Equals() on a number will simply convert the string to a number and check if the values are equal.
. Equals() on a BigDecimal allows you to convert the string to a BigDecimal by applying the rules described in the BigDecimal (String) constructor, to-wit:
The scale of the BigDecimal returned will be the number of digits in the fraction, or zero if the string contains no comma, subject to adjustment for any Exhibitor; If the string contains an exponent, the exponent is subtracted from the scale. The value of the scale that results must be between Integer.MIN_VALUE and Integer.MAX_VALUE, inclusively.
My conjecture only (since you don't seem to be ready to use the debugger and check), is that you have a scale on your BigDecimal which does not match the scale on the BigDecimal which is built from the identifier.
If I had to try to understand the difference between the two, I'd read the docs. Maybe even create a few test cases. Maybe to run my code in the debugger to see what that my BigDecimals and numbers looked like

Number n = new Number(1345); Integer iVal = n.intValue(); BigInteger lBigInteger = n.bigIntegerValue();I would use BigInteger instead...

in the sample, all of the same attributes of type number are ok.
What should correct let code to run? What remains behind the scenes on the definition of SelectOneChoice like that?Hello
1. the choice of a select uses "pActivityResultId" not "ActivityResultId" as in your code
2. the liaison is not of type AttributeBinding but JUCtrlListBinding if it is a model piloted by LOV
2. by default, selectOneChoices work with values of the index of the selected value, not the value itselfSee http://www.oracle.com/technetwork/developer-tools/adf/learnmore/dec2010-otn-harvest-199274.pdf
