Netbean Oracle : Problem with connection refused

Question

Hi, Im currently using Netbean to develop a system in JSP. I already succeed to connect to Oracle 11g. However, I'm facing problem connection refused. It always happen.
For the server, I using GlassFish Server 3.1
Any one have idea to solve this problem? Thanks in advances.

I already run the sql that you ask, this is the result
RESOURCE_NAME     CURRENT_UTILIZATION     MAX_UTILIZATION     INITIAL_ALLOCATION     LIMIT_VALUE
processes     26     150     150     150

This my function I use to connect to database
public class dbConnection {
public Connection conn=null;
public String id="Se";
public String password="See";
public dbConnection(){
public dbConnection (String id, String password){
this.id=id;
this.password=password;
public void connect(){
try{
//load driver
String driverName="oracle.jdbc.driver.OracleDriver";
Class.forName(driverName);
//Create connection
String serverName = "localhost";
Is it the same server on which db is running. Better put servername or IP for serverName above.
String portNumber = "1521";
String sid = "DEGREE";
String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber + ":" + sid;
System.out.println("url: " + url);
conn = DriverManager.getConnection(url,id,password);
}Can you try id/password@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = DEGREE))) from sql prompt and post the result.
catch(ClassNotFoundException e){
System.out.println("ClassNotFoundException: " + e.getMessage());
catch(SQLException e){
System.out.println("SQLException: " + e.getMessage());
while((e = e.getNextException()) != null)
System.out.println(e.getMessage());
}Everything goes OK, then download latest driver from oracle corporation and try again. A code sample can be found at http://www.orafaq.com/wiki/JDBC.
