Java Database Connectivity (JDBC)

Dear all,

I want my client application to connect informix database by using JDBC. The JDBC driver has been installed successfully in the client computer (Win2000). The informix 5.0 resides the a Unix server named "dbserver". The following is my java program.

========================
import java.sql.*;
import java.awt.event.*;

public class Application1 {

public static void main(String[] args) {
Connection conn;
try
{
Class.forName("com.informix.jdbc.IfxDriver");
}
catch (Exception e)
{
System.out.println("Error "+e.getmessage());
e.printStackTrace();
return;
}
System.out.println("It is ok");
try
{
conn = DriverManager.getConnection("jdbc:informix-sqli://dbserver:1526:INFORMIXSERVER=dbserver;username=test;password=******");
}
catch (SQLException e)
{
System.out.println("ERROR ."+e.getMessage());
e.printStackTrace();
return;
}
System.out.println("All is fine");
}
}
===========================

However, the error appears mentioning "Attempt to connect to database server (dbserver) failed." I don't know what the problem is because my informix database server is exactly "dbserver".

Kindly need help from you guys. Thanks in advance.
