问题 This question already has answers here : Failed to catch syntax error python [duplicate] (2 answers) Closed 2 years ago . from __future__ import print_function try: print "a" except SyntaxError: print('error') Why is the SyntaxError exception not being caught?

问题 I recently started using a custom ServiceHostFactory because I want to use dependency injection with WCF. Both my client and service are being run from VS2010 on my local machine and the service is using the ASP.NET Development Server. Why am I having this problem now? I've had success with wsHttpSecurity in the past, having both the client and service on my local machine. I really think the only difference here is the use of a ServiceHostFactory.

问题 When our application throws errors that we catch, we put the message and stacktrace in a log file created specifically for our application (myapp.log). For example: public class SomeClass { OurLogger log = OurLogger.getLogger ("myapp", SomeClass.class); public void someMethod { try { //code } catch (DataAccessException e) { log.error(e.getMessage(), e); } } } We do this because since we are in a environment where multiple apps reside on an application server...ours and every other
