Resultset doesn't return anything

Question

Hi, all
I'm using oracle9i Jdeveloper 9.0.3 preview version. When I ran a sql statement, it didn't return anything to my resultset. I wonder if you guys have any idea what's going on here. I tried the same sql statement in SQL Plus, it was working and returned 4 rows of record. I copy some source code from my severlet here. hope you can help me to resolve the issue.
package RCVCP;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.Vector;
import java.sql.*;
import java.text.SimpleDateFormat;
public class EnableDisableRules extends HttpServlet
private static String UrlE2;
* Initialize global variables
public void init(ServletConfig config) throws ServletException {
super.init(config);
UrlE2 = "jdbc:oracle:thin:@ASDE2DEVDB01:1521:EPID";
try {
               Class.forName("oracle.jdbc.driver.OracleDriver");
     } catch(java.lang.ClassNotFoundException e) {
          System.err.print("ClassNotFoundException: ");
               System.err.println(e.getMessage());
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
* Process the HTTP Post request
public void doPost (HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
Vector APPLYVct = new Vector(5);
Vector FILETER_NAMEVct = new Vector(5);
Vector DESCRIPTIONVct = new Vector(5);
String query;
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
int Rowindex=0;
try {
//checking the connection
con = DriverManager.getConnection(...) // I skipped here:)
if (con != null) {
stmt = con.createStatement();
rs = stmt.executeQuery("select APPLY, FILTER_NAME, DESCRIPTION from RCVCP_FILTER_RULES");
The program went wrong from rs statement right above.
Thanks.

Answer 1

the only thing I can think of is that
the account you logged on with is different fro
the account you tested with in sql*plus.
to eliminate that possiblilty prefix
the table name with the schema name
"select * from SCOTT.DEPT"
