Hi again,
this will be the last one for today ;-).
I figured out, that __Proxy0.class gets generated by the client. The
__Proxy0.class is always involved in this problem, regardless of where the
server or the client runs or what version of jdk or orion i use (meanwhile i
tried out 1.0.3, since it's the last "official" release), as if there was an
old copy of this class somewhere in my classpath which gets used. But on
neither of my machines i can find any instance of this class, except for the
directory where i start the client - and this one i have removed a hundred
times by now...
Can someone please explain, where, by whom and under which circumstances
this class gets generated (is it true, that the client must have write
access for the current directory to write this class? Or somewhere else?)?
Are there any other generated classes (so that i can search for old
instances of these) apart from those under "application-deployments" on the
server or clientside? Where are they placed if running the client within an
IDE (forte)?
Regards,
Jens
