(DECLARE_DYNCREATE and IMPLEMENT_DYNCREATE). .NET gives you this ability for any type without writing any extra lines of code. The static method Activator::CreateInstance(Type^) acts as the late-bound alternative to the operator gcnew. To instantiate a type, given its assembly-qualified type name, the following helper function can be used: Object^ CreateInstanceFromTypename(String^ type) { if (!type) throw gcnew ArgumentNullException("type"); Type^ t = Type::GetType(type); if (!t) throw gcnew ArgumentException("Invalid type name"); Object^ obj = Activator::CreateInstance(t); return obj; } For simplicity, this function expects the passed type to have a default constructor. Many types, including System::Uri, do not have a default constructor. To instantiate a type via a constructor with parameters, an overload for Activator::CreateInstance exists. This overload allows you to pass constructor arguments as an array of System::Object handles. The next line of code shows you how you can use it: Object^ CreateInstanceFromTypename(String^ type, ...array<Object^>^ args) { if (!type) throw gcnew ArgumentNullException("type"); Type^ t = Type::GetType(type); if (!t) throw gcnew ArgumentException("Invalid type name"); Object^ obj = Activator::CreateInstance(t, args); return obj; } In order to instantiate System::Uri with this helper function, you can use the following code: Object^ o = CreateInstanceFromTypename( "System.Uri, System, Version=2.0.0.0, " "Culture=neutral, PublicKeyToken=b77a5c561934e089", "http://www.heege.net" ); If you don t pass the correct argument types, a System::MissingMethodException will be thrown in Activator::CreateInstance.

Scheduled tasks are a reality for most nontrivial applications. For example, your business application may have to run a daily report to determine inventory levels and automatically send out restocking requests. For most legacy applications, it is typical to have a batch job to clean up temporary tables at the start or end of each day. If fact, it is fair to say schedulers are an essential holdover from the mainframe days of batch computing. As a result, scheduling tools, utilities, and frameworks have been a development mainstay for a long time. The Unix cron utility is probably the most popular and well-loved scheduling utility. The System Task Scheduler, generally lesser known, is the Microsoft Windows counterpart of cron. In the Java EE world, you have a few options for scheduling tasks and activities. Most Java EE application servers come with a scheduling utility that is sufficiently useful. There are also a number of feature-rich, full-scale scheduling packages available for enterprise applications. Flux is an excellent commercial scheduling package, while Quartz is a good-quality open source implementation. EJB timer services are the standard Java EE answer to scheduling. As you ll soon learn, while it does not try to compete with full-scale scheduling products, the EJB 3 timer service is probably sufficient for most day-to-day application development requirements. Because it is so lightweight, the service is also extremely easy to use. In the next few sections, we ll build a scheduling service using EJB 3 timers and show you how to use the @Timeout annotation.

In a sense, the EJB 3 timer service is based on the idea of time-delayed callbacks. In other words, the service allows you to specify a method (appropriately called the timeout method) that is automatically invoked after a specified interval of time. The container invokes the timeout method on your behalf when the time interval you specify elapses. As you ll see, you can use the timer service to register for callbacks triggered once at a specific time or at regular intervals. We can only use timers in stateless session beans and MDBs because of their asynchronous, stateless nature. However, unlike stateless session beans and MDBs, timers are persistent and can survive a container crash or restart. Timers are also transactional, that is, a transaction failure in a timeout method rolls back the actions taken by the timer. Figure 5.5 illustrates how timers work.
