ColdFusion provides two statements for exception handling in CFScript: try and catch. These statements are equivalent to the CFML cftry and cfcatch tags.
Exception-handling code in CFScript has the following format:
try {Code where exceptions will be caught
} catch(exceptionType exceptionVariable) {Code to handle exceptions of type exceptionType
that occur in the try block
} ... catch(exceptionTypeN exceptionVariableN) {Code to handle exceptions of type
exceptionTypeN that occur in the try block
}
When you have a try statement, you must have a catch statement. In the catch block, the exceptionVariable variable contains the exception type. This variable is the equivalent of the cfcatch tag cfcatch.Type built-in variable.
The following code shows exception handling in CFScript. It uses a CreateObject function to create a Java object. The catch statement executes only if the CreateObject function generates an exception. The displayed information includes the exception message; the except.Message variable is the equivalent of calling the Java getMessage method on the returned Java exception object.
<cfscript> try { emp = CreateObject("Java", "Employees"); } catch(Any excpt) { WriteOutput("The application was unable to perform a required operation.<br> Please try again later.<br>If this problem persists, contact Customer Service and include the following information:<br> #excpt.Message#<br>"); } </cfscript>
