IceGrid NullPermissionsVerifier not registered

Dear Ice experts,

I'm trying to play with the source code coming with the "Custom sessions and IceGrid" article that was published in issue 19 of Connections. I'm using Ice version 3.2.1 and after minor modifications to the code I was able to compile it. After modifying the config files as explained in the README file and deploying the services I tried to start the Glacier2 service but I see a strange error messages:
[ 01/08/08 13:42:48.297 Server: changed server `Mp3Ripper.Glacier2' state to `Loading' ]

[ 01/08/08 13:44:07.071 Activator: detected termination of server `localhost-manager'
signal = SIGABRT ]

First the Glacier2 service is not able to contact the NullPermissionsVerifier.
Then the session manager crashes.

I did not investigate further the cause of the crash. I thought that maybe sombody did try to make this example work and already solved the problem.

Thanks for your help.

    Hi,

    This is most likely because the Glacier2 configuration was written for Glacier2 from Ice 3.1.1. Could you try changing the value of the "Glacier2.PermissionsVerifier" property in the "ripperapp.xml" deployment descriptor to "${application}.Glacier2/NullPermissionsVerifier"? This should fix the problem -- the Glacier2 router will use its own permissions verifier rather than trying to use the IceGrid one which isn't accessible anymore.

    Cheers,
    Benoit.

    Hi Benoit,

    thanks for your prompt reply.
    Your suggestion solved the problem of Glacier2 not able to contact the NullPermissionsVerifier but the application is still not working.

    I'll continue to investigate but I would welcome any additional suggestion to solve the problem.

    Thank you for your help.

    Hi,

    IceBox services don't automatically inherit anymore from the IceBox server properties. That's what is causing indirectly this assert. Adding the following property in the "<icebox>" element of the "SessionManager" template definition in ripperapp.xml should fix the problem:
       <property name="IceBox.InheritProperties" value="1"/>

    Cheers,
    Benoit.

    Thanks for your Help Benoit.

    the problem is solved but the application still doesn't work. I'll have to investigate further.

    I just tested the demo with Ice 3.2.1. I had to make the following changes to get it work:

    Client.cpp
    Change #include <IceUtil/UUID.h> to #include <IceUtil/IceUtil.h>
    Add #include <set>

    SessionManagerI.cpp
    Change virtual const string ice_name to virtual string ice_name

    config
    Change the references to 192.168.1.5 in config to my hosts IP address.

    config.icegrid
    Uncomment the lines that say required for Ice 3.2.
    Comment out the IceGrid.Registry.Admin.Endpoints=default line.

    ripperapp.xml
    Change the references to 192.168.1.5 to my hosts IP address.
    In the SessionManager template <property name="IceBox.InheritProperties" value="1"/> under the icebox tag.
    Change <property name="Glacier2.PermissionsVerifier" value="EncoderIceGrid/NullPermissionsVerifier"/>
    to <property name="Glacier2.PermissionsVerifier" value="${application}.Glacier2/NullPermissionsVerifier"/>

    Once I did this everything worked as expected. I'm not sure why you get some other error.
