How can use ' Vector ' in JSP

I use rs.getString(1); can get three strings like "12:00-13:00", "01:00-02:00", "02:00-03:00" from sql 2000. I would like these time one by one, if it equals user select. System will show the message...then I use following code...but doesn't work because jsp said Vector not a type.(cannot resolve).... I would like to know any other methods can do the same things. hope sb help... thank you
Vector stringVector = new Vector();
while(rs.next()){
stringVector.addElement(rs.getString(1));
Iterator sv = stringVector.iterator();
while (sv.hasNext()){
if(time.equals((String)sv.next())
out.println("wrong");
else{
......

I personally would use an ArrayList. From what I hear, it's better than a vector. You want to make sure that you include the line at the top
<%@ page import = "java.util.ArrayList" %>
ArrayList stringVector = new ArrayList ();
while(rs.next()){
stringVector.add(rs.getString(1));
for (int i =0; i < stringVector.size(); i++){
if(time.equals((String)stringVector.get(i))
out.println("wrong");
else{No need to bother with any of that iterator stuff. My guess is that you're not including the Vector below, or a required jar file is missing (but Vector is part of the core java package, so the file can't be missing)

Help me!! How to use JavaScript with JSP ??

I am using JDeveloper and I created a screen in JSP which uses a bean for database connectivity and retriving info onto the page.
The page has a ListBox where list items are populated from the database.My requirement is
whenever the list is changed the page shuold be refreshed with the selected item info.
I tried to use 'JavaScript' for triggering the event with 'onChange' event of the ListBox.But the event is not getting invoked. I think JavaScript is not working with JSP.
Please help me with how to Use javaScript with JSP or any other alternative where I can meet my requirement.
I have one more question...I have gone through the JSP samples in OTN and I am trying do download the sample 'Travel servlet' which show list of countries...etc
I have also gone through the 'readme' but I don't know how to extract .jar file.
I would be great if you could help me in this.
Thanks!!

We have a similar need. We have used Cold Fusion to display data from Our Oracle Database. We have a simple SElect Box in HTML populated with the oracle data. When someone selects say the State of Pennsylvania. then we have an On change event that runs a Javascript to go get all the cities in Pennsylvania.
Proble we are having is that inorder for the Javascript to work , we currently have to send all the valid data.
Do you know of any way to dynamically query the the Oracle database in Javascript

How to use threads in JSP???

i want to write a jsp page which will
start 2 different threads. the 1st thread should just display a message and the second page should redirect this page to another jsp page.
till the redirection is goin on, the message should be displayed in the browser from the 1st thread.
i dont know actually how to use threads in JSP by implementing the Runnable insterface, if not m then how do i do it ??

Why do you want to use threads to do this ??
If you write a message and do a redirection, the message will be displayed until the other page will be loaded into the browser...
I already launched a thread from a JSP but it was for a four hour process where the user can close his browser windows.

There's a sample in the FABridge.zip download (called

There's nothing in the bridge that requires the framework.

How can use linux in my macbook?

how can use linux in my macbook?

You can use various distributions of Linux either by running them under Boot Camp, or in a virtualized environment such as Parallels or VMWare's Fusion. Note that you may have to try several different distros until you find one that works. I settled on Ubuntu running under Parallels.
Best of luck.

How can use my Wireless Location Appliance to work with RF ID's?

How can use my Wireless Location Appliance to work with RF ID's for Asset Tagging.
It seems Smartcard used for ID cards have a small RF ID, can I use this for Asset Tagging?
Thanks in Advance

There are two kinds of RFID tags: Active tags, which have a battery or other internal power source, and passive tags, which have no power source and work by reflecting the energy from an RFID scanner (basically). At the energy levels and distances used for WiFi location detection, passive tags will not return a detectable signal.
Take a look at http://www.aeroscout.com/ for more info on WiFi RFID tagging.
