Michalis, Loukik,

1. Names of properties to configure database are internal part of 
service, they don't need to be common. If I am alone in this statement, 
read next points:

2. There is nothing in the requirements for pS 3.0, the properties must 
be common for all services

3. LS does not use component for accessing DB, it even does not use 
pS-base (for performance reason) to do that, so the property name is 
different (internal)

4. Anyway, the "component.ma.xmldb...." is not so appropriate for:
     a) not using component
     b) not MA service

5. Michalis did his changes for my request. They were very good, exist 
servlet started to work for me.

6. The solution is easy -- servlet should try to get "new" properties 
from servlet.properties (if names are different) and if they're not 
there, it should try default. We use such schema for most of 
configuration code in LS (but I believe Roman does the same for MA - 
first use property, if there is no such property, use default value).
