Apex Class to export data to local system path

Hi,

i have a trigger for account object (after insert), which will invoke a apex class from which the newly inserted (trigger.new/) data must be exported to my local machine. 
Please guide me

thanks,
Karthik S

That isn't really possible. The problem is you are trying to get the backend of Salesforce to talk directly to your machine, which it can't do. You have a few options to get the data though.
  1. Send it to a web service. If your machine is open to the internet, you could send the data from the trigger to a web service running on your machine. You will have to call an @future method to make the web service call.
  2. Email it. You can have the results emailed to yourself or another account.
  3. You can use a HTTP Callout as well to send the data to specific endpoint.

Hi Chris Byrom,

thanks you for your response i was able to achieve the email method for exporting the data, but can you please guide me through the first method i.e. to invoke a Web Service from salesforce trigger.
Chris ByromChris Byrom
You can call a Web Service either REST, SOAP, or HTTP Callout from a trigger. You have to put the call in a seperate class and invoke it asynchronously. This means the method has to be annotated with the @Future method. This protects the platform from having long-running external operations during triggers.
