Call an Apex class from a button

I have an Apex class that I want to call from a button.  But I can't figure out how to call it from a button.
Note: I have tested this code inside a trigger and it works fine.
 
My button code is just (obviously this is wrong):
sforce.apex.execute("MyHelloWorld","doKPI", {});
 
The class code:
global class MyHelloWorld {

  WebService static void doKPI() {

    INTEGER NUM = 10;

    KPI__c[] tblkpi;

    tblkpi = new KPI__c[NUM];

    for (integer i = 0; i < NUM; i++) {
      tblkpi[i] = new KPI__c(UserName__c='user '+i, Signed_Contracts__c = i);
    }
    insert tblkpi;
  }
}

Gerhard,

I think you might need to include the connection.js and apex.js files at the top of your button JavaScript:

Code:
{!REQUIRESCRIPT("/soap/ajax/10.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/10.0/apex.js")}

If that doesn't fix your issue, you take a look at the Force.com Cookbook -- there's a recipe called "Creating a Button with Apex" on page 141 that shows a working example of a JavaScript button executing an Apex Web Service method -- perhaps there's something else in that example that will help you.

Hope that helps!

Thanks very much Caroline - that worked!

I was working from the salesforce_apex_language_reference.pdf document yesterday and nowhere in that does it tell me the answer you just gave me.  I recommend that the document be updated to include that example so other beginners don't get stuck on such a trivial problem.

Thanks again!

I'm glad that worked, Gerhard. I'll pass on your note to the Apex writer so that document gets updated ASAP!

Cheers,
Caroline

I too faced same issue. The buttons which were working fine all of a sudden started throwing "Sforce not defined" error. Post inclusion of those require scripts it started working.

Does anyone know if this method should work in the Customer Portal?  I've had success with using this method on a normal SF user account, but keep getting the following error when executed from the CP:

 

A problem with the OnClick JavaScript for this button or link was encountered:

{faultcode:'sf:INSUFFICIENT_ACCESS', faultstring:'NOCPortalSubmitForReview: no access allowed to this class.', }

Have you enabled the apex class for the customer portal profile in question?
