Calling commands through CORBA

Hi Falks,

I am investigating simple CORBA features for Orocos. The best way to
easily reproduce my problem is using an HelloWorld example.

On machine A, I launch
$ cdeployer-gnulinux -s hello.xml
in the helloworld folder with hello.xml being:
<properties>
<simple name="Import" type="string"><value>.<value><simple>
<struct name="Hello" type="OCL::HelloWorld">
<simple name="Server" type="boolean"><value>1<value><simple>
<struct>
<properties>

Then from machine B, I launch
$ ctaskbrowser-gnulinux Hello

CORBA connection seems OK (I can 'ls').

the_method gives me good results:
In Task Hello[R]. (Status of last Command : none )
(type 'ls' for context info) :the_method
Got :the_method
= Hello World

But I am not able to remotely call the command:
In Task Hello[R]. (Status of last Command : none )
(type 'ls' for context info) :the_command("Toto")
Got :the_command("Toto")
Fatal Semantic error: Something weird went wrong in calling method
"the_command" on object "this".

On machine A console, I have:
360.209 [ ERROR ][cdeployer-gnulinux::main()] CORBA exception raised
when creating ExpressionProxy!
360.209 [ ERROR ][cdeployer-gnulinux::main()] system exception, ID
'IDL:omg.org/CORBA/TRANSIENT:1.0'
OMG minor code (2), described as 'No usable profile in IOR.', completed = NO

Can anybody explain me this failure? and how to solve it?

Thanks,

Charles.

After a bit of Googling, I found this:

<http://www.qsyssoft.com/machaxor/?p=7>

.... If you get errors like "No usable profile in IOR" Then you will need to
check your /etc/hosts file. Make sure the line "127.0.0.1 localhost" also has
the name of your machine on the line.
ie. 127.0.0.1 localhost <mymachinename>

Good Luck!

That's ok, thanks !!



Effectively, this solve the problem. What looks strange is that I can
use methods, ls remote components, start them, without any error!



I am using RTT v1.6.



Thanks again.



Charles.

Before I dig into this further, which RTT version and did you patch/modify it
?
