Hi,

I just want to create a record in an object when i click button on the detail page.I have made the logic in an Apex class and calling the method by using javascript. Please see the following code

try
{
{!REQUIRESCRIPT("/soap/ajax/10.0/connection.js")}
{!REQUIRESCRIPT("/soap/ajax/10.0/apex.js")}
  
    var opportunityName ="{!Opportunity.Id}";
   alert("Hi");
   alert(opportunityName);
   sforce.apex.execute("QuoteToOrderConverterController","QuoteToOrderConverter", {a:opportunityName});
}
 catch(e)
{
alert("Error while converting from Quote to Order");
}

Here it 's showing Error as  {faultcode: 'soapenv:client', faultString: ' No Operation available for request {http://soap.sforce.com/schemas/package/QuoteToOrderConverterController}QuoteToOrderConverter,please checkthe WSDL for the Service.' ,}

Please assist.

Thanks in advance.
