Re: [one-users] Java OCA: poor choiche of Exception class

2011-04-28 Thread Carlos Martín Sánchez 
Hi there,

The RuntimeException looks better to me.

The only thing I'm not sure about is why you deleted the 'throws'
declaration from Client.java.
Doing that, a client application is not forced to catch the connection
problem.
I think it's better to force the coder to be aware of this kind of problems,
and prepare a nice error dialog, or a re-try mechanism.

What do you think about using the RuntimeException and
'public Client() throws OpenNebulaConfigurationError' ?


Best regards,
Carlos.

According to the last update in  issue #572

> "r" == redmine   writes:

r> Issue #572 has been updated by Ruben S. Montero.

r> Target version changed from Release 2.2 to Release 2.4

r> This is initially scheduled for 2.4

does the OpenNebula team plan to  include my contribution in the code,
and  if  yes, which  kind  of  exception  (the  Error or  the  Runtime
Exception) ?

I ask  this because I  am working on  a OVF aware  OCCI implementation
that relies on the OCA API (for Venus-C)  and I wonder if I can use my
modified code now or this spells trouble.

Zeeshan, your opinion is welcome, too!

Ticket #572  has been created.  There are two  version of the  Error I
add. The  firs one uses  java.lang.Error that is more  appropriate but
breaks the  legacy code. A  second version  does not change  the class
name (is  an Error after  all) but extends RuntimeException  since you
should  not write  a  catch  code for  it,  you  should provide  valid
resources for the program to run correctly.

One thing I forgot in the previous message:

I  know people  in Apache  Software Foundation  do such  raw Exception
throwing as  natinal sport, but in  my (again not so)  humble opinion,
ASF  java  coders  are  next  in  line  after  the  Sirius  Cybernetic
