>             Project: Karaf
>          Issue Type: Bug
>          Components: karaf-jdbc
>    Affects Versions: 4.0.1
>            Reporter: Sergey 
>
> 1st of all, current documentaion is wrong, because command names was changed 
> to jdbc:ds-info, for example, but 
> http://karaf.apache.org/manual/latest/users-guide/jdbc.html still contains 
> jdbc:info command names.
> Most important compatibility breaking change was another one: in karaf 3.x I 
> was able to deploy DataSource using spring-dm xml or blueprint, and it was 
> registered as a service and in jndi, and was listed using jdbc:datasources 
> command. Right now no datasources are listed.
