Throwing a standard exception with a particular message

I use a try/catch block with code similar to the following to display a variety of exceptions including validation errors. Shown below is the catch poriton:

 

        catch(Exception e)
        {
        	ApexPages.addMessages(e);
        }

 Now I would like to THROW a standard exception. i.e.

 

Try {

(Validate some condition)

}

catch (DMLException DMLe){

[How do I place code here that will provide a specific static message that i want to show as the particular exception message]

}

I don't think you can construct instances of standard Apex exceptions.  You will have to wrap your message in a custom exception created by extending standard exception.

If you are trying to push back a very specific / static message, you could have the different CATCH statements for different exceptions and do something like this:

 

try {
// Logic
} catch(exception e) {
ApexPages.addMessage(New ApexPages.Message(ApexPages.Severity.FATAL, 'whatever message you want'));
}

 

Is that what you're looking for?  Or are you looking to throw your own custom rolled exception?

Custom extension was the way to go.

 

I created a custom exception class similar to this article which is the easiest I have read on the topic: http://th3silverlining.com/2009/06/11/throwing-custom-apex-exceptions/

 

Then after creating a custom extension I simply inserted a bunch of IF statements and inside used the code below

throw new customException('My Text Here');

 

Worked well. Thanks to everyone for helping out.
