Null Object

My Java colleague wants to return a 'null' object reference should the
object instantiation fail when I invoke it through RPG. 

All the examples I've seen do not check for a 'null' object reference
and I was curious as to whether I could simply check for *NULL against
the field which holds the object reference? Should example code depict
the checking process?  They all seem to presume that they are going to
work!

 

The application is using an iSeries java class to access a web service
which will obtain the e-mail address of the iSeries user by accessing a
web service which interrogates the Active Directory. We are now using
single sign-on so the profiles are common. Anyone else done this? The
e-mail address will be used to e-mail  reports and Excel extracts to the
user.

 

Thanks.
