Exception
handling for Java clients for the IOM server is not significantly
different from exception handling for any other Java program. Many
methods in the stubs declare that they throw checked exceptions. When
calling those methods, you must do so in a
try block, and you must be sure to provide a
catch block that handles each possible exception.
The stub documentation
at
support.sas.com/rnd/gendoc/bi/api/iom/automj.html provides information about why each exception is thrown and what
to do when one is thrown.
Methods in the stubs
can also throw unchecked exceptions when there is an error related
to the distributed nature of your application. For example, an unchecked
exception might be thrown when the communications subsystem fails
or when the stubs are out of date relative to the IOM objects. All
of these exceptions are subclasses of
org.omg.CORBA.SystemException. A complete list of all subclasses is available in the CORBA specification.
Because they are unchecked exceptions, the Java compiler does not
require you to place your method calls inside a
try block.
