If you use ''Try..catch'' clause in your application, you don't need to worry about the exception handling of it on the web, because:

1. Appeon offers built-in exception handling mechanism to avoid serious problems occurring on the end-user's side.

2.As for the debug function which is offered by "Try..Catch" clause, Appeon also offers some replacements. You can use Appeon Debug tool together with Appeon Server and Appeon Error log files to debug the application when exception or error occurs.

3. When you deploy your application, Appeon Developer will automatically comment out the Try...catch clause, therefore, you don' t need to modify your code.
