Re: Re: Re: Re: Re: Re: Re: How to change remote JNDI-name in Jonas

Guillaume,

OK but if 2 Beans normally have the same package-name & ClassName in 2
different applications (different jar-components), there can be only 1
JNDI-entry for the remote interface. So there is the danger that 1
application is going to the wrong JNDI-entry.


For example we have 2 applications with each an account-component
(with Account-bean that is used for logon information). Last time when
I deployed the 2 applications, the one application was using the
account-data from the other application.

I hope it's a bit clear for you??

Greetings,

Stefaan Somers
