Hi , I have a trigger on opportunities after update, in the trigger am trying to get the Account object as follow:

for (Opportunity o : Trigger.new) {
.

.

.
acc=o.Account;
.

.

.
}

but the acc object is always null while the oportunity am updating has parent acount, whats wrong?

Hi , am writing an apex trigger in which I need to validate the account name if already exist before insertion... so this trigger event will be "before insert" on "Account" object... my question is there is a way from the trigger to stop the insertion process and rase an error or warning to the user that this account name already exist?

I have some "System.debug" statement in my apex class.. where can I see the output of these statements after executing the class?

Hi , where can i find the documentation on how to write unit test for my apex classes and triggers?

Hi, am running a future method in a pex class , I call this method in trigger after opportunity update, here is the trigger:

Trigger test on Opportunity(after update) {
  OppDateTest.updateOppDate();
  }

and here is the class and the future method am calling:

global class OppDateTest{

@future(callout=true)
  public static void updateOppDate() {
 
  Http h = new Http();

// Instantiate a new HTTP request, specify the method (GET) as well as the endpoint  
    String url='http://xxx.xxx.com/xxx/xxx.php';
    HttpRequest req = new HttpRequest();
    req.setEndpoint(url);
    req.setMethod('GET');

// Send the request, and return a response  
    
    HttpResponse res = h.send(req);
    String str=res.getBody();

  Opportunity[] opp = [SELECT id, name FROM Opportunity where name='test'];
    for (Opportunity o : opp) {
     o.description = str;
      update o;
      
      }

  }

}

but am getting this error whever the trigger fires:

I have an apex code in which am using the HTTP class to call a PHP page in external server and getting the following error all the time: "Invalid HTTP method"

when I open the page in a web broswer it opens and I can see the output so why am geting this error in the apex class , any idea?
