Trigger failed in document samples step by step

  1. I followed the instruction, step by step, and create the class "MyHelloWorld.cls" (just copied and pasted from the help)

  2. public class MyHelloWorld {
          // This method updates the Hello field on a list
         // of accounts.
               public static void addHelloWorld(Account[] accs){
      for (Account a:accs){
                        if (a.Hello__c != 'World')
      a.Hello__c = 'World';
                                                     }
                                                                                              }
    }

  3. I am still OK up to this point.  The problem occurred when I create the trigger below:

  4. Trigger helloWorldAccountTrigger on Account
    (before insert) {
    MyHelloWorld.addHelloWorld(Trigger.new);
    }

  5. The error = "Method does not exist or Incorrect Signature"

  6. Can you please let me know what is my problem?

Problem in Calling Yahoo web Service from Apex class

Hi,

I want to call Yahoo web service through REST protocol from my apex code.

I am using following example given in apex language reference guide. I have just replaced my url in the code.

public class HttpCalloutSample {
// Pass in the endpoint to be used using the string url
public String getContent() {
// Instantiate a new http object
Http h = new Http();
// Instantiate a new HTTP request, specify the method (GET) as well as the endpoint
HttpRequest req = new HttpRequest();
String url = 'http://travel.yahooapis.com/TripService/V1.1/tripSearch?appid=YahooDemo';
req.setEndpoint(url);
req.setMethod('GET');
// Send the request, and return a response
HttpResponse res = h.send(req);
return res.getBody();
}
}

I am calling following line from my S-Control (in my javascript function)
var success = sforce.apex.execute("HttpCalloutSample", "getContent", {});

I am getting following exception.

faultcode soapenv:Client
faultstring No operation available for request {http://soap.sforce.com/schemas/package/HttpCalloutSample}getContent, please check the WSDL for the service.

So what is the problem? Is it a right way?
Does anyone have any example code or syntax show how I would make that call?

Thanks

MyHelloWorld Trigger wont fire

Hi, I'm just trying to get the MyhelloWorld trigger to work from the 'Quickstart with Force.com IDE guide' - (on my developer site), and I can't seem to get it to work. Can someone tell me what I am doing wrong?
 
Here is the code:
 
APEX Class:
public class MyHelloWorld {
public static void addHelloWorld(Account[] accs) {
   for (Account a:accs) {
     if (a.Hello__c != 'World') 
     a.Hello__c = 'World';
}
}
}
APEX Trigger under Account: 
trigger helloWorldAccountTrigger on Account (before insert) {
MyHelloWorld.addHelloWorld (Trigger.new);
}
 
API Name on Account Record is: Hello__c
