[ace-users] Naming Service problem

[Douglas C. Schmidt]

Hi Vishnu,

   Thanks for using the PRF!

>    ACE VERSION: 5.5.8

Please upgrade to ACE+TAO+CIAO x.6 (i.e., ACE 5.6, TAO 1.6, and CIAO
0.6), which you can download from

http://download.dre.vanderbilt.edu

under the heading: "Latest Release."

The DOC groups at Washington University, UC Irvine, and Vanderbilt
University only provide "best effort" support for non-sponsors for the
latest release, as described in

http://www.dre.vanderbilt.edu/~schmidt/DOC_ROOT/ACE/docs/ACE-bug-process.html

Thus, if you need more "predictable" help for earlier versions of
ACE+TAO, I recommend that you check out

http://www.dre.vanderbilt.edu/support.html

for a list of companies that will provide you with ACE+TAO commercial
support.

Sure, but I think you need to do this

   CosNaming::Name name (2);
   
rather than

   CosNaming::Name name;

Please take a look at the Henning and Vinoski book on "Advanced CORBA
Programming with C++" or McHale's "CORBA Explained Simply"
<http://www.ciaranmchale.com/download/corba-explained-simply.pdf> for
more info.

Thanks,
   
   Doug
