Better error reporting from CryptoFactory.loadClass() [patch]
-------------------------------------------------------------
Key: WSS-20
URL: http://issues.apache.org/jira/browse/WSS-20
Project: WSS4J
Type: Improvement
Reporter: Thomas Leonard
Assigned to: Davanum Srinivas
loadClass() first tries to construct an instance of cryptogenClass with a
single properties parameter to the constructor. If this fails, it tries again
with no arguments. If this second attempt fails, it reports a generic message
saying "cannot create instance". This is not very helpful, as it does not pass
on any error reported by the code.
Perhaps it would be better to check which constructor exists, use that, and
report any error back to the user? I have a patch to do this, which I will
attach.
Note: This causes a change in behaviour if the class has *both* constructors,
since it will only try the one which takes the parameter. However, I think this
is more likely to be the correct behaviour.
