Method to test if the value is a number or a string?

Hi Everybody !!!
Do you know a method that permit to test if the value is a number or a string?
Thanks !!!

What kind of value is it? Is it a String and you want to test if it holds a number or characters? If so, use toCharArray() on the String to convert it to a char array and use Character.isDigit() and/or Character.isLetter() on each of the char array elements to test it's type.

11.1.1.4:Could not find the item selected to match the value of type Number

Hi,
I have a taskflow with an input parameter.
The input parameter value is to be assigned to a list item as the default selected value.
I have mapped the pageFlow scope parameter to set value to the list item using input page parameters defined in task flow.
but When i Run the task flow the value does not get assigned to the drop down list and jdevloper console screen shows up the following message
"Could not find the item selected to match the value 2 by type: oracle.jbo.domain.Number in LOV."
But If I click the Lov to check the values it shows that value is present in the list.
The same configurations works if the list of values is for a column with type as java.lang.String.
Is it somethng different that is to be done for a Number field to assign value from a taskflow parameter?
Edited by: user3067156 on Jun 25, 2011 3:34 PM

Hi Jobinesh,
I am assigning the default value in the task flow using input page parameters ...
<view id="VIEW1">
<page>/title.jsff</page>
<input-page-parameter>
<from-value>#{pageFlowScope.pInputTyp_Id}</from-value>
<to-value>#{bindings.pTyp_Id1.attributeValue}</to-value>
</input-page-parameter>
</view id>
It does not assign the value, if Bind variable(pTyp_Id1) NDtype and task flow input parameter(pInputTyp) class type, both are set to use type oracle.jbo.domain.Number.
If I change both to use java.lang.String and additionally also change the VO defination the accept the bind variable of type string, it assigns the value correctly.
Usecase:
I have a a task flow for which has its first page a search page.
The Search page is created using operation execute with params and dragging the query parameters on the page.
The Query parameters are to be filled using a select one choice option and the list is bound to the master values.
This task flow can be used inside a standalone page as a region to provide a search page
The same task flow can be called from within another taskflow which will provide the default values for the drop down lists ..
Since the search page is a jsff fragment i dont have a page on load handler to provide default values..
So assiging the values using input page parameters defined in task flow view tag.
For testing I am passing the taskflow input parameters by calling the task flow from a jspx page a region . When I configure this task flow a region in a page its asks for providing the values for the parameters
And the same gets configured in my testpage def as
<executables>
<variableIterator id="variables"/>
<taskFlow id="Flow1" taskFlowId="/WEB-INF/Flow1.xml#Flow1"
activation="deferred"
xmlns="http://xmlns.oracle.com/adf/controller/binding">
<parameters>
<parameter id="pTyp_Id" value="1207"/>
</parameters>
</taskFlow>
</executables>

Changing the value of the SOAPElement in the SOAP message

Now another problem I encountered was of overwriting a value in the SOAP message by my value. SOAPElement interface which extends Node interface provides me the method getValue() to get the value of the node but doesnt give me any method to set any other value instead of this.
<token xsi:type="xsd:string">token123</token>
I want to replace the value "token123" with my value.
Is there no provision for altering a value in the SOAP message? Is this due to security contraints?
If yes then can we detach the same node and add a similar node with the new value. I wanted to try the same using addChildElements() method but then the problem here is how do I create a new SOAPElement in the handler as its an interface and not a class. Why I want to add a similar node is because I am having the definition of this object in the WSDL file, so if I attach the node corresponding to the parameter of the object then I would get the object populated with this value at J2EE or .net layer.
Also I thought of adding an attribute to the same node but then since this attribute will not be defined in the WSDL, the value of this attribute will not populate the java object at the J2EE layer. Hence attribute introduction also didnt help.
This is the userData object in the soap body:
</q1:FetchDetailsInput><q2:UserData xmlns:q2="java:com.anthem.enb.common.data" xsi:type="q2:UserData" id="id2">
<password xsi:type="xsd:string">12345</password>
<token xsi:type="xsd:string">token123</token>
<userID xsi:type="xsd:string">vikas123</userID>
</q2:UserData>
This is my code to extract the values from the above message:
Iterator i = ctx.getMessage().getSOAPPart().getEnvelope().getBody().getChildElements();
System.out.println(" i.hasNext() =" + i.hasNext());
while (i.hasNext())
Object obj = i.next();
System.out.println(" obj :" + obj.getClass());
if (obj instanceof SOAPElement)
SOAPElement e = (SOAPElement) obj;
System.out.println("e :" + e);
String operationName = e.getElementName().getLocalName();
LOG.info(CLASS_NAME + "operationName :" + operationName);
if (operationName.equals("UserData"))
Iterator j = e.getChildElements();
LOG.info(CLASS_NAME + " j.hasNext() : " + j.hasNext());
while (j.hasNext())
Object obj2 = j.next();
LOG.info(CLASS_NAME + " obj2 :" + obj2);
LOG.info(CLASS_NAME + " obj2 :" + obj2.getClass());
if (obj2 instanceof SOAPElement)
SOAPElement eGrandChild = (SOAPElement) obj2;
String operationName2 =
eGrandChild.getElementName().getLocalName();
if (operationName2.equals("userID"))
String strPass = eGrandChild.getValue();
LOG.info(CLASS_NAME + " strPass:" + strPass);
else if (operationName2.equals("password"))
String strUserID = eGrandChild.getValue();
LOG.info(CLASS_NAME + " strUserID:" + strUserID);
else if (operationName2.equals("token"))
String strToken = eGrandChild.getValue();
Please help.

how do I create a new SOAPElement in the handler as its an interface and not a class?Here is an example:
<example>
MessageFactory messageFactory = MessageFactory.newInstance();
SOAPMessage m = messageFactory.createMessage();
SOAPEnvelope env = m.getSOAPPart().getEnvelope();
SOAPBody body = env.getBody();
SOAPElement fResponse =
body.addBodyElement(env.createName("fResponse"));
fResponse.addAttribute(env.createName("encodingStyle"),
"http://schemas.xmlsoap.org/soap/encoding/");
SOAPElement result =
fResponse.addChildElement(env.createName("result"));
result.addTextNode("test");
ctx.setMessage(m);
</example>

Getting the Values from a Tiled View

Hi,
I have a TiledView and I have checkbox in the tiled view. I am trying
to get the values of the checked boxes.
I have coded like this.
Object[] links = getRSystemLinks().getCbSystemUrl().getValues();
if I see the links.length i get only one. In html If I see the code
it appends the TileIndex in brackets. If I replace the TileIndex with
0 in all the fields in endCbSystemUrl method I get the correct values.
In the TiledView beginDisplay() method my code is like this.
if (getPrimaryModel() == null) throw new ModelControlException
("Primary model is null");
super.beginDisplay();
resetTileIndex();
pgCustomizeLinksViewBean parentBean = (pgCustomizeLinksViewBean)
getParent();
((DatasetModel) getDefaultModel()).setSize
(parentBean.SystemChoicesValue.size());
Any Suggestions on this.
Thanks
Namburi

Namburi--
Remember, the getValues() method does not return the values from a column in
a TiledView. It is strictly for use by fields that can have multiple
values, like multi-select list boxes.
DO NOT remove the indexing feature from the field names, especially in the
case of checkboxes, because checkboxes aren't submitted back to the server
unless they are checked. By overriding the automatic checkbox tracking
feature JATO provides, you won't be able to tell which checkboxes were
actually checked by row--you'll simply get back a list the same size as the
number of checkboxes that were checked, without any placeholders for the
ones that weren't checked.
Instead, on submit, you simply need to move through the tiledView and check
the value of checkbox on each row:
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
You can use the same construct to build up an array or list:
List checkedList=new LinkedList();
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
checkedList.add(new Boolean(true))
else
checkedList.add(new Boolean(false))

How to find out the type of the value stored in a string variable?

Hi,
How do i find out the type of the value stored in a string variable?
for example,
I have a string variable str, in which the following type of values wil be stored
1) Intger
2) Long
3) boolean
4) Char
Is there any method to find out the type of the value, anything like str.getType()?. Please kindly help me. Thanks in advance.

Hi All, i'm sorry for the double posting, by mistake it occured.
Thanks for your replies, i have a string variable str, in which the value is stored and i have another string variable type, in which the type of the value is stored.
For example,
String str = "15";
String type = "Integer";
Is there any way to verify whether the value stroed in str is of type stored in the variable 'type'. I want to write a method of type boolean, it will throw true of the value stored in str is of type 'type'. Thanks

How to monitor the values transferred to the jump query in a debug mode?

Dear experts,
There is a problem in the interface of two qeuries. In the first query, the infoobject is defined as a global filter with a constant. I added this infoobject in the interface via RSBBS.
Nevertheless, if i run the jump query, the value in this InfoObject is not taken into account by the jump query.
Does anybody know whether there is a method to debug (monitor) the values tranferred to the jump query? For example, in the transaction RSRT or others.
Thanks in advance!

in RSRT- EXECUTE+DEBUG => breakpoint in RRI transpormations
also see the note 1053310

How do you set the value of an enumeration programatically

I would like to be able to select (programatically) the value of an enumeration. I don't seem to be able to find any reference to how to do that.
Thanks.
Solved!
Go to Solution.

True, True. The original post wanted to know how to programmatically "select" the enum value. To me, that means to either force the enum to display another value, or retrieve the current value. I thought Ben was referring to the fact that you can't programmatically set or initiate new values into an enum. Which as he said, can only be done with a Ring.
"In your example you're not "getting" the value of the enum. You're converting it to a string. That's a different operation."
I showed two ways to get the value, one gets the current string value associated with the numeric value, and the other gets the current numeric value. i went further in the attached vi, by demonstrating how to change the current (displayed) value of the enum by using a string. (IFF you already know the string values in the enum.)
In my program, i use a typedef cluster with an enum in it. At runtime, i need to "select" the active enum value based on which operation i'm performing. I know from elsewhere in the program what operation i need, but it's string, and there's no easy way to change the value of an enum with a string, except with the backdoor methods i showed.
I wish my cohort woulda used a ring. ;-)

Clear the values in Drop down by key

hi all ,
i m using drop down by key (Combo box) ..
i have populated some values in that ..
then i navigate to next view ... from that view i m again navigating back to the
previous view .. now the values which was filled needs to be cleared ..
i used invalidete method also even though the values are present in the list ..
can any one help in this ...
points will be rewarded
Thanks and regards
JK

Hi,
Do you want the currently selected value to be reset, or do you want to delete the entire list of values? If you want to only reset your current selection, node->invalidate( ) should do it. Invalidate your node in the inbound plug handler.

How to caluculate the values by day

Hi,
Shortly suppose if i give the date as nov10 it should caluculate the values of 8th and 9th and place the value in 10th.
How to work on these by variables or is there any other method to caluculate.

Calculate the values of 8th and 9th? What is the calculation? If you have values of those two days and if you want to sum up the values and show it for the 10th, you can simply use the offset on the date variable in two columns restricted to respective key figure and in another column which should be a new formula, can sum up the other two columns.
If your requirement is not simple as you have mentioned I mean if there is some logic in calculating values for the two dates, depending upon the complexity, you can use an exit too. Please elobarate the requirement if it is not simple................

Copy the value from one item into another

Hi,
I have a page with 2 items on it: Field1 and Field2. When the user enters a value in Field1 and tabs out, I want to copy the value to Field2.
I have changed the setField1 method in the VORowImpl to call setField2 passing in the same value.
In the JHeadstart definition file I have set the Depends On Item property of Field2 to be Field1.
When I run the page and put a value in Field1 the page autosubmits as expected and the setField1 method runs. Unfortunately, the value does not appear in Field2.
Any ideas?
Thanks,
Gavin

Hi Steven,
Checking the box does indeed get the value from Field1 into Field2.
What I want to do, though, is to populate Field2 from Field1 only if Field2 is empty. Unfortunately, Field2 is now cleared before the setter of Field1 executes and so it always overwrites Field2.
Any ideas?
Thanks,
Gavin

Need help parsing a long and passing the value.

I'm doing Cattle Drve 4b on javaranch.com (http://www.javaranch.com/say.jsp) and I need a bit of help.
I want to pass the reference of my num value to several small methods to work out the value printed. Here's the original code I did from 4a:
public class Say{
public static void main(String[]args){
int num = Integer.parseInt(args[0]); // parse argument from command line
String array[] ={"Zero", "One", "Two", "Three", "four", "five", "six","seven","eight",
           "nine","ten","eleven","twelve","thirteen","fourteen","fifteen","sixteen",
           "seventeen","eighteen","nineteen","twenty","thirty","fourty","fifty",
           "sixty","seventy","eighty","ninety"};     //initialize the array
//start check for value
if(num<21)
System.out.println("\n" + array[num]);
                                        // \n is added before
else if(num<30)                                   // each result for a
System.out.println("\n" + array[20]+ "-" + array[(num-20)]);     // cleaner output
else if(num<40)
System.out.println("\n" + array[21]+ "-" + array[(num-30)]);
else if(num<50)
System.out.println("\n" + array[22]+ "-" + array[(num-40)]);
else if(num<60)
System.out.println("\n" + array[23]+ "-" + array[(num-50)]);
else if(num<70)
System.out.println("\n" + array[24]+ "-" + array[(num-60)]);
else if(num<80)
System.out.println("\n" + array[25]+ "-" + array[(num-70)]);
else if(num<90)
System.out.println("\n" + array[26]+ "-" + array[(num-80)]);
else if(num<100)
System.out.println("\n" + array[27]+ "-" + array[(num-90)]);
//endFor 4b I need to be able to print out values in the billions, so I was going to create a few methods to keep it clean like so:
public class billion (long (int num)
{ if( num<9 billion)
     num-= 8 billion
System.out.print("eight billion ");
else if(num<8 billion){
num-= 7 billion
System.out.print("seven billion ");
....etc
return num;
public class million...
public class thousand...
etc.And the current main section will be moved into a new "tens" class.
I'm running into two problems though.
1. How do you parse a long? I know integers are like so:
int num = Integer.parseInt(args[0]); are longs the same?
like:
long num = Long.parseLong(args[0L])if not, how can I do it?
2. how do I properly pass num to all the methods? I'm going to make num a public int and make the methods public because that seems simplest, but can I pass num to the method and then return the new value of num back to main?
BTW, I'll be removing the carriage return from the beginning of the "tens" class when all is said and done so the results don't end up printing on multiple lines.
Thanks in advance everyone.

The L suffix is used to identify a Long literal.
The index of the args[] array does not need to be specified as a Long.
Solong num = Long.parseLong(args[0]);will suffice. You might want to put that in a try/catch block to catch the NumberFormatException that will be thrown if args[0] cannot be parsed to a long value.
Various ways to update the value of num in the methods of the same class:
Simplest of all: declare num as an instance variable. The methods simply access and assign its value.
Other ways:
-- pass num as a parameter to the method.
-- return the value of num from the method (provided the method doesn't have to return any other value)
-- Have a getNum() method return the value of num
-- Have setNum() method to update the value of num
db
What's that line? public class billion (long (int num)edit Typos, typos...
Also, the set/get approach with public access is the preferred method when used in the methods of another class.
Don't forget that the other class has to know whose set/get methods to call.

How to get the values of all rows in advanced table

HI All,
I am using an advanced table to enter the values for the service contract line (its a custom page)in that advanced table i ahave column with lov called task number for that task number once i had choosed one task number and creating one more row using add anethor row button i want to restrict the user to not to choose the task number which was entered in the previus row.
Or if this is not possible i want to restrict the user by showing an error message when click on the submit button by saying you have choosed the duplicate task number please choose a uniqu task number
please give some hints
thanks
ajay

Hi
your approach will have two steps
1.) use the row refernce and get the value of task number of the row which is enterd by user .
2.) use getRows in range and compare values of task number of every row with the user selected value ,if value match then throw error.
Thanks

Hi,
Is that possible to bring that value to the define

Error trying to change the value property of a cell with decimals

This is a script question.
I’m using a system defaulting to Spanish, so the decimal delimiter is the comma.
During a script I need to change the property value of a cell multiplying it by -1. As an example, I want to change 1,25 into -1,25.
This is how try to do it:
tell application "Numbers" to tell document 1 to tell sheet 1 to tell table 1
set selection range to first cell
set mi_cell to (value of first cell of selection range) * -1
set value of first cell of selection range to mi_cell
end tell
The expected result is wrong provided that the original value of the cell has decimal value. Otherwise is correct.
See examples of what happen after running this piece of the script:
1,25 becomes -125,00 instead of -1,25
6,00 becomes -6,00 (in this case is correct)
Does anybody know how to solve this problem?
Thanks in advance.
Ratz

This was described here in several scripts.
Before setting the value of a cell to a number or a date, the value must be coerced to a string.
It's the only way available to take care of localization features.
Your script must be
tell application "Numbers" to tell document 1 to tell sheet 1 to tell table 1
set selection range to first cell
set mi_cell to (value of first cell of selection range) * -1
set value of first cell of selection range to mi_cell as text
end tell
or better
tell application "Numbers" to tell document 1 to tell sheet 1 to tell table 1
set mi_cell to (value of first cell) * -1
set value of first cell to mi_cell as text
end tell
CAUTION : don't code
tell application "Numbers" to tell document 1 to tell sheet 1 to tell table 1
set mi_cell to -(value of first cell)
set value of first cell to mi_cell as text
end tell
which is supposed to do the same but would return the opposite of *_the integer value_* of the cell.
