web application question

[kalyen kumar]

Hi,

I am developing a web application which sells books online.
Once an user buys a books from this site then 2 things should happen,

1) An Email confirming the order details, amount and shipping details should be sent to the user.
2) Also an SMS confirming the same order details, amount and shipping details should be sent to the user.

If i do it like first email and next sms then any problem in sending email is not allowing the sms sending to trigger.

Question: What is the better approach (apart from thread based approach) to make sure, the sending email and sending sms are independent of each other ?
Failure in one should not obstruct the other.

Thanks in advance
Kalyan

Hi Kalyen,

You can surround the code for sending email and sms with 2 different try-catch blocks.
Ex:

try{
    sendEmail();
}catch(EmailException){
    // log exception and notify user
}

try{
    sendSMS();
}catch(SMSException){
    // log exception and notify user
}
