JDBC does not allow to collect an information for the database you are not conected to. The method getCatalogs does not return databases, instead it returns the catalogs in current database. To list down the available databases, you need to query the catalog tables. For example, on postgres you can use :
  select datname from pg_catalog.pg_database where datname not in('template0','template1')
  This will populate all the databases.

  Dear all,

I have a remote machine, which is ushing Postgres v.7.4.11.
This machine has 2 database :
Database A & Database B

I have a task to list out the available database inside that machine in a combo box. I have tried to using :

public String getDBList()
        String s = "";
            connection_this = DriverManager.getConnection(sURL, sUser, sPassword);
            dbMetaData_this = connection_this.getMetaData();
            resultSet_this = dbMetaData_this.getCatalogs();

                    s += ",";
                s += resultSet_this.getString(1);
            return s;
        catch(SQLException e)
            return "error";

This will only return the database, that I state inside the URL
(e.g. String sURL = "jdbc:postgresql://<<ip>>:5432/databaseA"  ---> will return "databaseA" only).

I try to connect without stating any database inside the URL, also cannot.
Can you guys please help me ?

Thank you.
