GetTableName using ResultsetMetadata. Not support ???

Question

I am using JDBC driver for MS SQL Server 2000 to connect to SQL Server 2000. In this I need to know the tablename of columns in the underlying query structure of the Resultset. The resultsetmetadata method getTableName() is not supportive. It returns "".
My code :
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
conn = DriverManager.getConnection("jdbc:microsoft:sqlserver://DBTest:1433","sa","");
strSQL = "SELECT * FROM Test.dbo.tables1";
stmt = conn.createStatement();
rs = stmt.executeQuery(strSQL);
ResultSetMetaData rsmd = rs.getMetaData();
System.out.println("strTableName = " + rsmd.getTableName(1));
Can anybody help me in this regard. Any concerns are appreciated.
Thanks a lot.

Since you are selecting from a table, you already have the table name in the SQL, so I'm not sure what you are really trying to get at with your code.
That said, if you need to get the table names from the database, you have to query the database to fetch the table names.
The following code dumps all the tables by schema and type after connecting to SQL Server:

import java.sql.*;
import java.util.*;
class ConnectApp {
    public static void main(String args[]) {
        try{
            // Load the driver
            Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver");
            // Connect to the database
            Connection connection=DriverManager.getConnection("jdbc:microsoft:sqlserver://myhost:1433;databasename=pubs","myUser","myPassword");
            // Get database meta data
            DatabaseMetaData meta=connection.getMetaData();
            // Display meta data information
            System.out.println("Database: "+meta.getDatabaseProductName());
            System.out.println("Product version "+meta.getDatabaseProductVersion());
            System.out.println("User name: "+meta.getUserName());
            System.out.println("Driver: "+meta.getDriverName());
            System.out.println("Driver version: "+meta.getDriverVersion());
            System.out.println("SQL keywords: "+meta.getSQLKeywords());
            System.out.println("===================================");
            System.out.println("Schema term: "+meta.getSchemaTerm());
            System.out.println("===================================");
            System.out.println("Catalog term: "+meta.getCatalogTerm());
            System.out.println("===================================");
            ResultSet rsSchema = meta.getSchemas();
            String [] sa = { "none" };
            while (rsSchema.next()) {
                System.out.println("For " +meta.getSchemaTerm()+ " " + rsSchema.getString(1));
                ResultSet rsCatalogs = meta.getCatalogs();
                while (rsCatalogs.next()) {
                    System.out.println("\tFor " + meta.getCatalogTerm() + " " + rsCatalogs.getString(1));
                    ResultSet rsTableTypes = meta.getTableTypes();
                    while (rsTableTypes.next()) {
                        sa[0] = rsTableTypes.getString(1);
                        System.out.println("\t\tFor TableType '"+sa[0]+"'");
                        System.out.println("\t\t===================================");
                        ResultSet rsTables = meta.getTables(rsCatalogs.getString(1), null, "%", sa );
                        ResultSetMetaData mdTables = rsTables.getMetaData();
                        int columnCount = mdTables.getColumnCount();
                        for(int i=1; i<columnCount; i++) {
                            System.out.print("\t\t" + mdTables.getColumnName(i) + "\t");
                        System.out.println("");
                        while (rsTables.next()) {
                            for(int i=1; i<columnCount; i++) {
                                System.out.print("\t\t" + rsTables.getString(i) + "\t");
                            System.out.println("");
                        rsTables.close();
                    rsTableTypes.close();
                rsCatalogs.close();
            rsSchema.close();
            // Close the database
            connection.close();
        }catch(Exception ex){
            System.out.println(ex);
            System.exit(0);
