Ola pessoal,

estou tento um pequeno problema com o ResutSet:

con = new DBConnection();				 
System.out.println("yes");
st = con.createStatement();
System.out.println("yes");
			 
 rs = st.executeQuery("SELECT * FROM user");

o erro:

yes
yes

seria isso:

private ActionListener setUser = new ActionListener()
	 {	
		 DBConnection con = null;
		 Statement st;
		 ResultSet rs = null;
		 private String password, user = null;
		 
		 public void actionPerformed(ActionEvent setUser)
		 {			 
			 try
			 {
				 con = new DBConnection();				 
				 System.out.println("yes");
				 
				 st = con.createStatement();
				 System.out.println("yes");				 
				
				 rs = st.executeQuery("SELECT * FROM time.user");
				 System.out.println("yes");				 			 
			 }
			 catch(SQLException sqle)
			 {
				 sqle.printStackTrace();
			 } 
			 catch (SecurityException e)
			 {
				
			 } 
			 catch (IOException e)
			 {
				
			 }
		 }
	 };

um actionlistener para uma botao!
