visibroker and bind

#1 04-07-2004, 12:27 PM

Hi,

Does anybody out there know if its possible for an old visi client
(java based) and implemented on visi 3.2.2 to bind to a new POA based
visi server. The server is implemented in C++ and uses the latest
version of the visi ORB.

I have upgraded the server to a POA based setup and would like to
leave the clients unchanged. I can call the server POA's anything I
like and likewise the OID's for the servant in question can be called
anything I like. So is it possible for this to happen? Or am I obliged
to upgrade the client and use some flavour of the new bind( ) method?

thanks a million

If the BindSupportPolicy of the POA is BY_INSTANCE, the old style
bind() should still work. If this policy is BY_POA (default), you need
use the new by_poa bind().

Your client/server should interoperable, regardless the proprietary
bind(). You can use IOR/URL or naming service etc..

Ke,

you are a jedi wudan warrior of legendary proportions. May you drink
deeply from the cup of nice warm fuzzy shiney happy things.

You just saved me from having to totally upgrade and port a production
client while fixing the build system in parallel !

Eh, thanks.
