String alphabetical checking / validation

Hi
I am wanting to check that a String is only composed of alphabetical characters or spaces. Is there a nice API in the JDK that I can use to check / validate this String?
Thanks

Regular expressions are the nice way to do it.
The code below will check to see if a String is composed of any combination of alphabetical characters or spaces.
String str = "Hello from me";
boolean result = Pattern.matches("[a-zA-Z ]+", str);result =trueNote that the ' ' (single white space) in your "[a-zA-Z ]" will not match tabs or other white space characters. If you also want them to match, you can use:
"[a-zA-Z\\s]+"
// \\s means (almost) any white space character

How to determine if string represents a valid numeric

Using Labview (6.1), what is the easiest way to determine if a string represents a valid numeric?

Try using the "Scan From String" function on the string palette. Using
a format specifier of "%f" or "%d" will try to format the string into a
number. If the string contains anything besides numbers, the function
should generate an error.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

The time string has a valid format but it corresponds to the future time

First all, I want to thank richwolf ... without his Woolamaloo.. I don't know if I can every have this to work---> for a person that is not a programmer, that application really helps a lot.
When I use the debug function in Woolamaloo, it gave me the information about that time string has a valid format but it corresponds to the future time. And, because of that only "all" access is allowed.
If we can't change the server time setting, is there any way I can modify the script to correct this? I place the modified itunesu (from the apple sample code, shell folder) file to the cgi-bin folder on the server. Any help will be really appreciated thank you all.
Trouble R.

First of all, thank you for using Woolamaloo. You are too kind.
The time token is used to create your signature token ... and you need the signature to have a valid token string. So I can't see a way for you to do what you ask.
Is there any way you can use the server that you don't control to do authentication only ... and generate the token string on a server whose time you can set?

try converting the string to an array of the letters, sort the array, and then convert the sorted array back into a string. you should be able to figure out the rest. Look at the API for String for the methods you need.

Can Check Valid From task be run on multiple JVMs in clustered env.

The configuration screen for the Check Valid From scheduler task allows it to be run oin more than one JVM in a clustered environment.
Has anyone done this?
Does this cause any problems?

Hello Timothy,
This is not recommended for any scheduler task as it potentially means that the task could be run multiple times and would most likely lead to inconsistencies in the results of the task. Have a look at SAP note 798633 which discussed this a little more.

String Language Checking

Hi,
what is the best way to check that a certain string matchs a certain language, for example i have user input name (String) where i need to validate that its Arabic, is it recommended to use the uni-code ranges checking, or is there a better way of doing so.
Thanks in advance

That question has been asked tons of times.
Mostly you are out of luck.
Using Unicode ranges you can check the script at best. And usually several languages share a script (many western languages share the Latin script, for example).
If you had more data about each language you need to identify (for example a complete dictionary of each language), then you could do a more in-depth analysis to find out which language it probably is. This can get hard (and even impossible) if the text you need to identify is short (just guess in how many languages "a" is a valid word).

Given String Date is valid/not?

Hi Friends,
I am getting date in string format e.g.
          String creationDate = "2007/02/30";
I want to check is valid or not. see in the example I have given 30 Feb 2007 which is invalid date. Is there any way to check the date is valid or not.
Any help will be appreciable for me.
Thanks in advance...
- Hiren Modi

use the java.text.SimpleDateFormat. The strategy is to instanstiate a SimpleDateFormat with the date pattern and then parse the input string with it to produce a java.util.Date. This in turn is fed back in the same SimpleDateFormat instance for formatting resulting in a String which is then compared to the input string. If they are not equal then the input string is an invalid date. something like
String input = "2007/02/30";
        String output = null;
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd");
        try {
            Date date = sdf.parse(input);
            output = sdf.format(date);
            if (!input.equals(output)) throw new IllegalArgumentException("invalid date"); // or however you want to handle it
        } catch (ParseException ex) {
            ex.printStackTrace();
        }

How to check validation for a input field?

For example, I need to check the validation of a field, if OK, then the field will be inputted, otherwise, there will rise a message, how can I implement that?
Thanks and best regards,

Hi Andres,
U can write a code in Request Processing--DO_VALIDATE_INPUT
DATA: LR_BTADMINH       TYPE REF TO   CL_CRM_BOL_ENTITY.
LR_BTADMINH ?= ME->TYPED_CONTEXT->BTADMINH->COLLECTION_WRAPPER->GET_CURRENT( ).

Checking/Validating user input in a text field

How can I validate a user's input in a text field and require them to input it in the following format:
AAA 9999-999
(where A can be letters and 9 can be numbers)
Is there any documentation on how to validate user inputs in this manner?
Thanks!
BoilerUP

Hi,
Create a validation PL/SQL process, select Function returning Error and use something similar to the example below.
I tested it but may be I missed something. I used field name P1_TEST.
DECLARE
v_number NUMBER;
v_error VARCHAR2(1000);
BEGIN
--check if you have numbers in positions 5-8 and 10-12
v_number:=SUBSTR(:P1_TEST,5,4);
v_number:=SUBSTR(:P1_TEST,10);
--check string length
IF LENGTH(:P1_TEST)!=12 THEN
RETURN 'String length must be 12 characters';
END IF;
--check if position 4 is empty
IF INSTR(SUBSTR(:P1_TEST,4,1),' ')=0 THEN
RETURN 'There should be a space between letters and numbers';
END IF;
--check if position 9 has "-"
IF INSTR(SUBSTR(:P1_TEST,9,1),'-')=0 THEN
RETURN 'There should be a dash between numbers';
END IF;
--check if positions 1-3 has letters
FOR i IN 1 .. 3 LOOP
SELECT ascii(substr(:P1_TEST, i, 1)) INTO v_number
FROM Dual;
IF v_number>=48 AND v_number<=59 THEN
RETURN 'Only letters are allowed in positions 1,2,3';
END IF;
END LOOP;
RETURN NULL;
EXCEPTION
WHEN OTHERS THEN
v_error:=SQLERRM;
IF INSTR(v_error, 'ORA-06502')>0 THEN
RETURN '...must be integers only';
ELSE
RETURN v_error;
END IF;
END;
I hope it will give you an idea on this type of validation.

How can I display an icon, instead of text string, as a validation prompt?

My validate method inside my custom validator is like this:
public void validate(FacesContext context, UIComponent component, Object value) {
Pattern datePattern = Pattern.compile("(\\d{2})/(\\d{2})/(\\d{4})");
Matcher dateMatcher = datePattern.matcher((String)value);
if(!dateMatcher.find()){
    ((UIInput)component).setValid(false);
    FacesMessage message = new FacesMessage();
    String msg = "[" + value + "] invalid date";
    message.setDetail(msg);
    context.addMessage(component.getClientId(context), message);
    FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_FATAL, "xx", "msg");
    throw new ValidatorException(facesMsg);
}My JSP has this:
<h:inputText id="test" value="#{projecthandler.test}">
<f:validator validatorId="DateValidator" />
</h:inputText>
<h:message id="testErrorMessage" for="test"/>The <h:message> tag will kick in if the user has invalid data in the <h:inputText> field and clicks submit.
When the page is regenerated, the user will see a text string reflecting what the issue is.
However, instead of this, I would like to display an icon consisting of a red circle with an exclamation point.
The user is supposed to click on the icon if they want more information. By clicking on the icon,
the user will see a message box, with a description of the error.
This is our standard for applications. I'm trying to put together a demo showing how an existing application
would work in JSF, so I won't be able to talk others into using JSF, unless I can get the validation to display an
icon instead of text.

OK, I noticed a bug in my validate method. This is updated to fix the bug, and to include the recomendation about background-image:
public void validate(FacesContext context, UIComponent component, Object value) {
    System.out.println("DateValidator.test.1");
    Pattern datePattern = Pattern.compile("(\\d{2})/(\\d{2})/(\\d{4})");
    Matcher dateMatcher = datePattern.matcher((String)value);
    System.out.println("DateValidator.test.1");
    if(!dateMatcher.find()){
      ((UIInput)component).setValid(false);
      FacesMessage message = new FacesMessage();
      String msg = "<span style='background-image: url(/error.gif)'/>";
      message.setDetail(msg);
      message.setSeverity(FacesMessage.SEVERITY_FATAL);
      context.addMessage(component.getClientId(context), message);
      throw new ValidatorException(message);
}When I run this, the litteral string of "<span style='background-image: url(/error.gif)'/>" is printed as the message. It does not interpret this as a span tag with an image url.
Can someone tell me what's going on?

How to check validity of data reference

Hello everybody,
in my application I use a help class to buffer data objects.
This class contains one attribute which is an internal table ( columns: DATAID and DATAREF )
I use this databuffer to transport data between different classes.
Now I did the following mistake:
First I call the method 'METH_CHECK'. As import parameter I pass a reference to my databuffer class.
In method 'METH_CHECK' I call a function module 'FUNC_1' passing my reference to my databuffer class.
In 'FUNC_1' I declare a local variable 'lv_value'.
Then I use the statement 'GET REFERENCE OF lv_value' and save this reference into my databuffer class.
After processing functions / methods I´m back at the point where 'METH_CHECK' was called.
When I check my databuffer class, I´ve got one entry in it.
The reference I saved while processing 'FUNC_1' . But the referenced data has already be freed ( remember, it was a local variable ).
In the debugger I see the column where I save the references to data objects.
The field value has changed from a valid reference to i.e. 'FREED ITAB: 5'...
OK, I know what is wrong... No problem in my application, but I want to clean
this entry... How can I check this...
I can not check like
LOOP AT me->buffer INTO wa_buffer.
    IF wa_buffer-data IS INITIAL.
      DELETE...
    ENDIF.
ENDLOOP.
or
LOOP AT me->buffer INTO wa_buffer.
    IF wa_buffer-data CP 'FREED'.
      DELETE....
    ENDIF.
ENDLOOP.
How can I notice an invalid reference at this point?
Thank you very much,
Oliver Seifer

Hello Oliver,
Another approach might be to avoid any dependency to the caller at all.
Regards
Klaus
data:
    buffer_Reference type ref to data.
field-symbols:
   <buffer_Data> type data.
create data buffer_Reference like i_Value.
assign buffer_Reference to <buffer_Data>.
<buffer_Data> = i_Value.

How to ReUse Existence Check Validation ?

Hi All,
I read chapter 9.6.2 of ADF Developer Guide 4GL, "9.6.2 Implementing an Efficient Existence Check". However the exists() method in the ProductDefImpl.java can only be use to check product existence when user add new product on Product entity .
But in my case, there are many entities having FK referring to Product
entity, e.g :
OrdersDetail has FK to Product
PurchaseDetail has FK to Product
ShipmentDetail has FK to Product
..and some more...
I don't want to code productExists() method to all xxxDefImpl class of all
above entities. How can I create just one productExists() method and reuse it in all entities having FK to Product entity ?
Thank you for your help,
xtanto

Hi Steve,
yes, I have check to ServiceRequestImpl in SRDemo, there is a method validator that invoke productDef.exists(getDBTransaction(),data).
But, by using method validator, I still have to copy-paste the code to ALL entities that has FK to Product.
How to make it a Reusable Validation Rule (like "DateMustComeAfterRule") so that I just need "plug" it to All entities (at attribute level) having FK to Product ?
Thank you,
xtanto

Check validation of WBS and AGENT at SC level instead of PO creation time.

Hi all,
is there any function module to check the issues with the account assignment like agents are missing for cost center or WBS for a shopping cart , this is validated during PO creation but my requirement is to validate it during the SC Cart creation .
Thanks
Aditya

Hi Adidya
You are correct. Indeed all checks happen during PO only not through SC.
You can use DOC check badi only
