Changes in CORBA Features Between J2SE 1.4.x and 5.0 (original) (raw)
When the J2SE 5.0 ORB marshals an org.omg.CORBA.SystemException
response, it adds an ExceptionDetailMessage
(i.e., a ServiceContext with ServiceId 14
) as defined in:
/**
* CORBA formal/02-06-01: 13.7.1:
* ExceptionDetailMessage identifies a CDR encapsulation of a wstring,
* encoded using GIOP 1.2 with a TCS-W of UTF-16. This service context
* may be sent on Reply messages with a reply_status of SYSTEM_EXCEPTION
* or USER_EXCEPTION. The usage of this service context is defined
* by language mappings.
*
* IDL/Java: ptc/02-01-22: 1.15.2:
* When a System Exception is marshaled, its GIOP Reply message shall
* include an associated ExceptionDetailMessage service context. The
* callee's stack trace is often very valuable debugging information but
* may contain sensitive or unwanted information. The wstring within the
* service context will therefore contain additional information relating
* to the exception, for example the result of calling either
* printStackTrace(PrintWriter) or getMessage() on the exception. When
* unmarshaling a System Exception on the client side, the wstring from
* any ExceptionDetailMessage service context shall become the Java error
* message in the unmarshaled exception object.
*/
When the J2SE 5.0 ORB unmarshals an org.omg.CORBA.SystemException
response it constructs the SystemException
with the contents of theExceptionDetailMessage
as the message
argument to theSystemException
constructor.
NOTE: The content of the message may change. In J2SE 5.0, the message contains the server side stack trace. The following code example (note: all details may change) of a stack trace on the client side for an exception generated on the server-side (note the server-side stack trace in the exception's message):
