How to check an existence of a table or column?
I've loaded jdbc deriver and call (driverName).getConnection().getMetaData().getColumns(..,String tableName, String columnName)- it allways returs false - what's wrong?

Try
Connection con = DriverManager.getConnection(url,properties);
DatabaseMetaData dbmd = con.getMetaData();
ResultSet rs=dbmd.getColumns(null, "%", "aTableName", "%");
