Proper error handling is a key points in any application. If you are using WSO2 Jaggery, then you might have also come up with the same requirement.
Jaggery is JavaScript, hence
try, catch and
finally blocks can be used within your code as you usual. Also, passed JavaScript
Error object can be used to get a brief information about the error. But, as we are dealing with a server side environment, we might need to know additional details about the errors, such as stacktrace, line numbers etc.
Using the additional properties/methods which can be found in the passed
Error object, error details can be accessed as below.
var log = new Log();
try {
parse(null); //code where exception is thrown
} catch (e) {
log.error(e.lineNumber); // Error occured line number
log.error(e.fileName); // Error occured script name
log.error(e.stack); // Executed JavaScript file stack
log.error(e.message); // JavaScript error message
log.error(e.rhinoException); // Rhino exception object
log.error(e.javaException); // Java excepton object
log.error(e); // Logs the stack trace
print(e); // prints the stack trace
} finally {
log.info('finally :)');
}
