Subject Re: Managed Properties question

OK, another try

<bean id="containerManaged" class="ContainerManagedBean">
   <osgix:managed-properties persistent-id="labX"
   <property name="integer" value="23"/>

this is the official example :)

I think the property (named integer here) is optional. Usually all
properties which can be read through getter and setter can be set by
the configuration.

So your problem is that you try to inject properties within another property

<property name="hibernateProperties">
    <prop key="hibernate.show_sql">${myAppDbShowSql}</prop>
    <prop key="hibernate.format_sql">${myAppDbFormatSql}</prop>

All your properties you want to update need to be accessible via
getter and setter.
If you want to do this you need to make an extra bean which is
configurable (with the same pid)
and inject that one after it is initialized. you may want to make your
standard bean dependend on the "new" bean.
