Hi,

I am trying to make a callout to a Siebel Web Service to send the account created.

Here is what I did so far :
1. Generated the Classes from WSDL received from Siebel
2. Remote Site Setting Maintained with the URL ( http://192.168.XX.XX/SOME_PATH)
3. Created sample VF page for account Creation
4. Controller is implemented to perform call out with a @future Method
5. In the @future method, which is doing the callout actually, I have provided the access parameters for auth in the header like shown in the below code :

Still I am wondering why would this callout failed ?

Please suggest me what would have been missed or any workaround to get this resolved ?

Code of Controller :

public with sharing class calloutAccount {

    public Account account { get; private set; } 

    public calloutAccount(ApexPages.StandardController controller) 
    {
        Id id = ApexPages.currentPage().getParameters().get('id');
        account = (id == null)? new Account() : [SELECT Name, AccountNumber, Account_Status__c FROM Account WHERE Id = :id];
    }
    
    public PageReference saveAccount() 
    {
        try 
        {
            upsert(account);
        } 
        catch(System.DMLException e) 
        {
            ApexPages.addMessages(e);
            return null;
        }
        //  After successful Save, navigate to the default view page
        PageReference redirectSuccess = new ApexPages.StandardController(Account).view();         
                           
        DoCallout(account.Id,account.Account_Status__c);       
            
        return (redirectSuccess);
    }
    
    public PageReference cancelAccount() 
    {
        //  After Cancel, navigate to the default view page
        PageReference redirectSuccess = new ApexPages.StandardController(Account).view();
        return (redirectSuccess);
    }
    
    @future(callout=true)
        private static void DoCallout(Id actID,String actStatus)
        {   
            Account account = [SELECT Name,AccountNumber,Account_Status__c FROM Account WHERE Id =: actID];  //Query for the inserted account ABOVE
                
            System.debug(' @@@ acccount ID from FUTURE menthos() = '+ account.Id);
                                       
                string UName = 'username'; 
                string Passwd = 'password';
