wll you might have missed to get my point, lemme give you an example:
in your validator,After getting your view Iterator
for(Row row:iter1.getAllRowsInRange){   \\here iter1 is your view iterator
if(valueEnteredByuser.equalIgnoreCase(row.getAttribute("col1").toString())){   \\here col1 is your attribute that contains the value and valueEnteredByuser is the value entered by user
      throw new validatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR,"Data Exists"));
}let me know if you need some other help :)

How to search for upper/lower case using string using JAVA!!!?

-I am trying to write a program that will examine each letter in the string and count how many time the upper-case letter 'E' appears, and how many times the lower-case letter 'e' appears.
-I also have to use a JOptionPane.showMessageDialog() to tell the user how many upper and lower case e's were in the string.
-This will be repeated until the user types the word "Stop".
please help if you can
what i have so far:
[code]
public class Project0 {
public static void main(String[] args) {
String[] uppercase = {'E'};
String[] lowercase = {'e'};
String isOrIsNot, inputWord;
while (true) {
   // This line asks the user for input by popping out a single window
   // with text input
   inputWord = JOptionPane.showInputDialog(null, "Please enter a sentence");
   if ( inputWord.equals("stop") )
    System.exit(0);
   // if the inputWord is contained within uppercase or
   // lowercase return true
   if (wordIsThere(inputWord, lowercase))
    isOrIsNot = "Number of lower case e's: ";
   if (wordIsThere(inputword, uppercase))
     isOrIsNot = "number of upper case e's: ";
   // Output to a JOptionPane window whether the word is on the list or not
   JOptionPane.showMessageDialog(null, "The word " + inputWord + " " + isOrIsNot + " on the list.");
} //main
public static boolean wordIsThere(String findMe, String[] theList) {

In the User Administration section of your portal find your newly created user and below select "Assigned Roles" tab then press <Modify> button and look through available roles on portal then just simply add and save. But if you want to do it programmatically see below:
IUserAcountFactory userFactory = UMFactory.getUserAccountFactory();
// IUser - read only but with IUserAccount is possible to set up user data
IUserAccountSearchFilter userFilter = userFactory.getUserAccountSearchFilter();
userFilter.setLogonUid("superuser", ISearchAttribute.LIKE_OPERATOR, false);
ISearchResult sr = userFactory.search(userFilter);
for (final Iterator i = new PrincipalIterator(sr); i.hasNext();) {
IUserAccount user = (IUserAccount) i.next();
Execute the same search for IRole (or IGroup if needed) get the unique id of them and use newRole(...) and addUserToRole(...) methods from IRoleFactory.
Of course you don't need search for this principals if you know uniqueness of them. Use appropriate factories to get'em all by this unique id.

How to assign a value for Unit of measure (like PC, KG...) in ABAP program?

Hi,
    How to assign a value for Unit of measure (like PC, KG...) in ABAP program?
    I want to assign PC in a field to execute the program, like wa-ENTRY_UOM = 'pc'.
    But the system returen a message that "Unit of measure is not convertible to stockkeeping unit PC"
    Could anyone tell me how to assign the value??
    Thanks!

hi,
first convert the quantity in the same unit ( like in you case ST to PC ) by using FM :    MD_CONVERT_MATERIAL_UNIT
CALL FUNCTION 'MD_CONVERT_MATERIAL_UNIT'
    EXPORTING
      i_matnr                    = matnr
      i_in_me                    = entry_uom
      i_out_me                   = out_uom
      i_menge                    = quantity
   IMPORTING
     E_MENGE                     = fp_l_v_quant
   EXCEPTIONS
     ERROR_IN_APPLICATION       = 1
     ERROR                      = 2
     OTHERS                     = 3.
IF sy-subrc <> 0.
          give error message here
   ENDIF.
bcoz in ur program somewhere the quantities etc are compared and there units may be different... so that is why it is showing such error. so just convert convert the quantity in the same unit .

rahul

How to set the name for an 'unknown' file extension?

Specifics:
I have various file extensions that are recognized by my mac. I would like to know how to create a list of applications that can open it so I do not get a 'There is no Default Application to open this file' error. I would also like to be able to give these file extensions names recognized by the mac.
Just like .txt is a "Textedit Document" and .html is a "HTML Document," I'd like to be able to change the name and assosication of a file and give it its own .icns if possible.
As for the default applications, I know how to set a default application. However, if a mac does not recognize a file extension, adding a new default application to run the file wil actually erase the old one, which is a big pain, especially when your file can be opened with ANY text editor.
I understand that this may involve hacking into the operating system's databases, but if anyone can help, it would be greatly appreciated.

Hi Timo,
My jdev version is 10.1.3.3.0, this is for R12. By PR i mean to say process request and PFR process form request in the controller.
In the Process request of the controller, i am finding the checkbox bean and assigning the firepartialaction for it.
Later in the process form request for the fired event, i am trying to handle the rendered property of the messagetextinput. Is this a right approach?
my code below
public void processRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
super.processRequest(oapagecontext, oawebbean);
OAApplicationModule oaapplicationmodule = oapagecontext.getApplicationModule(oawebbean);
OAMessageCheckBoxBean oamessagecheckboxbean = (OAMessageCheckBoxBean)oawebbean.findChildRecursive("X_FLAG");
if(oamessagecheckboxbean != null)
oapagecontext.writeDiagnostics(this, "Message check box Bean found:", 1);
FirePartialAction firepartialaction = new FirePartialAction("change");
oamessagecheckboxbean.setAttributeValue(PRIMARY_CLIENT_ACTION_ATTR, firepartialaction);
oamessagecheckboxbean.setFireActionForSubmit("change", null, null, true);
oapagecontext.writeDiagnostics(this, "setting fire event", 1);
public void processFormRequest(OAPageContext oapagecontext, OAWebBean oawebbean)
super.processFormRequest(oapagecontext, oawebbean);
oapagecontext.writeDiagnostics(this, "Inside Process Form Request", 1);
if("change".equals(oapagecontext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
OAMessageTextInputBean bean = (OAMessageTextInputBean)oawebbean.findChildRecursive("X_NUMBER");
if(bean!=null){
bean.setRendered(Boolean.TRUE);}
