Hi,

Not sure if this is the same problem but I found that by adding the postgres JDBC driver to the classpath of all sequoia controllers the client recieves the message straight away. I traced this problem back in the sequoia 2.4 days to be related to the fact that the group software couldn't serialize the SQLException to transmit accross the cluster because it couldn't load the exeception class and thus caused a runtime error on the remote controller...
Dave is right, if you have any database specific object that gets returned through the group communication (SQLException or ResultSet), then the database driver should be in the classpath.

Thanks for your interest in Sequoia,
Emmanuel
