How to find the OWNER of a table with JDBC metaData?

Question

Hi,
i write a dynamique dataBase gui for multiple dataBase (oracle, postgre..)
I want to use JDBC meta data to configure the gui
I can't find methode to optain a specifique table list for a owner...
with getTablePrivileges I see the Grantor but not the owner (the grantor isn't always the owner)
and I can't use schema because schema isn't supported by postgre
some one can help me ?
thanks a lot

Yes of course but it is DataBase dependent...
and I want to use different DataBase...And what sort of owner would you expect in a MS Access
database?
if they are only one user we work only whith one "schema owner" the data base is structured in this way
but when multi user is possible we want to work with specifique relation beetwen different user ...
we want to use users because more dataBase suppport multiple owner than multiple schema
and generaly our information are divide in
genereral and referential information ( explain of data and list of values etc ...)
and the specifique data.
And our GUI distingue the "META DATA" and the pure "DATA" and propose specifique properties to interact with those data
i hope that my problem is better explain now .
example we use
resultSet = connection.getMetaData().getTables("","%","%",new String[]{"TABLE","VIEW"});
to optain all the table and view
resultSet = connection.getMetaData().getTablePrivileges(null,null,"tableName");
to optain privileges for a table
the trouble is that in specifique catatalog table like oracle we find a colomn whith the owner properites and when we use getTablePrivileges we can't see it idem for posgree
Each privilige description has the following columns:
TABLE_CAT String => table catalog (may be null)
TABLE_SCHEM String => table schema (may be null)
TABLE_NAME String => table name
GRANTOR => grantor of access (may be null)
GRANTEE String => grantee of access
PRIVILEGE String => name of access
IS_GRANTABLE String => "YES" if grantee is permitted to grant to others; "NO" if not; null if unknown
has you see we have GRANTOR information but not OWNER information
and the GRANTOR isn't allways the OWNER ...
