Exceptions

An exception (exceptional event) is an event that disrupts the normal flow of program instructions while that program is running. JTAPI defines nine types of exceptions. A few of these exceptions are:

• PlatformException and ProviderUnavailableException extend Java's RuntimeException. This permits them to be thrown from any method without being declared. When developing your program, be sure to include try and catch blocks to facilitate the processing of these two exceptions.
• MethodNotSupportedException (indicating that the method which was invoked is not supported by the implementation) is thrown when the function is not supported by the underlying infrastructure or when an application invokes an Action method on a dynamic Terminal or dynamic Address. These two dynamic objects, dynamic Terminal and dynamic Address, are temporarily created to represent resources that are not owned by the Provider.

For more information about these and the other six exceptions, refer to the JavaSoft JTAPI 1.2 documentation.
