Friedhelm,

Could you please make sure that you didn't use any wonrg/obsolete IORs 
generated by CIAO, since you mentioned it tries to connect to the wrong 
component? Before investigating this problem further, I would suggest 
delete all the IOR files generated by CIAO in the directory of your file 
system and try again.

Thanks,
Gan
