I am getting a StatusCodeException. May I am a bit more specific: I
have to check concurrency problems. In case of a concurrency the GUI
has to show a user dialog. The StatusCodeException just give me the
ErrorCode 500 (Internal Server Error) but this is to unspecific. This
error code can occour in other cases as well so that I need another
identifier.
The original exception is capsulated in the message body of the
StatusCodeException with HTML tags. A dirty solution would be to make
a String RegEx and search for a pattern which identify the concurreny
exception in the exception message. But there must be a more elegant
way of doing this?!
So how can I do this better without an RegEx or string search?
This would be the message of the StatusCodeException:
