Question

public HashMap getAllColumnsNameInTable(String tableName){
     HashMap tableColumnMap = new HashMap();
     ArrayList columnNameList = new ArrayList();
     ArrayList columnTypeList =new ArrayList();     try{

         Connection con = getConnection(ds);
         Statement statmt = con.createStatement();
         ResultSet rs;         String queryString = "Select * from " + tableName;
         //System.out.println(systemQueryString);
         try{

            ResultSetMetaData rsMeta = rs.getMetaData();
            for(int i =1; i<=rsMeta.getColumnCount(); i++){
               columnNameList.add(rsMeta.getColumnName(i));

             }
