Help with jsp (timer)

Greetings,
I'd like to know whether following possible or not - perform a task that will make something when time goes out (like an auction system) with visual preview of ticking counter (24:00, 23:59 ... etc. when the page refreshed)?..
Or I should use Javascript fot it? But how it will work if user will disable Javascript on it's pc?..
Thanks...

Greetings,
I'd like to know whether following possible
possible or not - perform a task that will make
something when time goes out (like an auction system)
with visual preview of ticking counter (24:00, 23:59
... etc. when the page refreshed)?..Yes, you can use a Meta-Refresh to refresh the page every x seconds. The client will send a new request to the server and redisplay the page with updated content (as long as you provide the updated content).
<meta http-equiv="refresh" content="2;url=thePageToSendTo">Where content has two parts - the first a number representing how long to wait until a refresh occurs. The second (after a ;) being the url to send the browser to after the period of time expires.
Note - users can block meta-refreshes as well.
Or I should use Javascript fot it? But how it
how it will work if user will disable Javascript on
it's pc?..You can use Javascript, or use a combination of Javascript and Pushlets to do the task. If the user turns JS off, the page is broken. Give them a message saying that, in order for this page to work correctly, Javascript needs to be enabled. Giving a simple message like that is easy:
<html>
<head>
    <script type="text/javascript">
      function hideJSWarning() {
        var JSWarning = document.getElementById("JSWarning");
        JSWarning.style.display = "none";
    </script>
</head>
<body>
    <div id="JSWarning">
      You currently have Javascript disabled. In order for this page to function
       correctly, you need to enable JavaScript.
    </div>
    <script type="text/javascript">hideJSWarning();</script>
    <br />The rest of your page
</body>
</html>See, when the user has JS enable, the hideJSWarning function gets called, and the user doesn't see the warning. When the user does not have JS enabled, then the <div> holding the warning is not hidden, and the user sees the warning stating that they need JS enabled.

Need help with new Time Capsule/Airport express setup!

I just hooked up a 500g time capsule to replace an airport extreme, and now my airport utility on my MacbookPro Retina no longer recognizes the airport expresses I had on my network for airplay purposes. Can anyone help with this issue?

Instead of a switch you need a wireless router, because your modem will only assign one public ip address to the switch and that ip address will be forwarded to any one computer at a given time...You should replace the switch with a wireless router and it should resolve your concern...

I don't see anywhere in your code where you conditionally output a tuple from your database. You seem to be outputting everything.
Maybe you need:
<% if (sSSN==input_value){ %>
<TD><input TYPE="checkbox" name="<%=rowID %>" ></TD>
<% } %>

Help with JSP and logic:iterate

I have some queries hope someone can help me.

And I have the RequestData.java file:

private int requestID = 1234;
public int getRequestID() { return requestID; }
The jsp page display:

0 RequestData@5b6d00
0 RequestData@514f7f
0 RequestData@3a5a9c
0 RequestData@12d7ae
0 RequestData@e1666
Seems like the requestID is not returned. Does anybody know this?
I have done the exact one using JSP and servlets, trying to learn using JSP and custom tags. The one with JSP and servlet looks like:
============================================
<%@ page import="RequestData" %>
<%Iterator data = (Iterator)request.getAttribute("Data");
while (data.hasNext()) {
   RequestData RD = (RequestData)data.next();
   out.println(RD.getRequestID() );
}%>

Oh think I got it...
but one thing I'm not sure is...
If I use "<jsp:useBean id="RD" class="RequestData" />", do I still need "<%@ page import="RequestData" %>"?
I tried without and it gives me error...

Please help me.....

Actually you're probably off on a false trail with jsp:useBean. The more up to date methods use tag libraries (typically JSTL) and access bean attributes using EL, bean expression language. E.g. you put your initial form data into a request attribute called "data" and you put:
<input type="text" name="property1" value="${data.property1}" ....useBean is no use for binding returned fields from a form. Always remember that your JSP generates HTML and once that HTML is sent to the browser that's it, the JSP has done it's job and finished. Only with JSF, at present, does what you write in your JSP affect the processing of received form data. When you get the form data back you need to "bind" the values from the request back to the bean. A framework like Spring will do this stuff for you, but in a raw Servlet/JSP environment it's up to you.

Help with JSP/Weblogic/Tomcat Discrepencies

Hi,
          I have something very strange happening. I recently did some JSP stuff on
          WLS60SP1 and all went quite well. I then took those same JSP pages and tried
          them out on the latest release of TOMCAT. I was really impressed that
          everything seemed to be completely transparent and working just fine until
          the following situation:
          When I reference, within a JSP page, an object that has previously been
          added to the request scope that has just been created, but not messed with
          in anyway...meaning all the attributes in this bean have their default
          values set...and they are all Strings with the exception of one Integer
          using this format:
          <%= custVal.getCustomerNumber() %>
          - In WLS, what shows in the text field on the form is nothing, because
          customer number in the custVal object is null (default for a String)..this
          is what I want.
          - In Tomcat, what shows it the word "null".
          ...here is the weird part, by changing from scriptlet references to the
          <jsp:getProperty....> format such as....
          <jsp:getProperty name="custVal" property="customerNumber"/>
          -In WLS, he is still a happy camper and works just fine regardless of how I
          reference the bean
          -In Tomcat, I also get the correct results that I want.
          So, unlike most postings, I found out how to fix it but I would like to know
          why...any ideas?
          Thanks in advance,

Help with JSP Forward !!!

I have 3 pages ...1) index.jsp 2) Forward.jsp 3) welcome.jsp
I have 2 fields in the index.jsp once upon filling & hit submit it has to to go Forward.jsp page...in the Forward.jsp..i have coded only one tag with
<jsp:forward page="welcome.jsp" />
I have one question...once the page comes to Forward page...will it display the contents of the Welcome .jsp in the same page itself...or it will go to Welcome.jsp page..
As i saw it will display the contents of Welcome.jsp page in itself...
Please let me know...
Regards
Gnanesh

I understand your question only because I have a set up totally identical to yours. The thread Matt suggested does explain the situation (i.e. the server passed control to another page but the client doesn't know that), but doesn't necessarily give a good solution a problem that you may have, and that I do have:
If the user sees the welcome page, and for some reason decides to "reload", the forward page is re-executed, even though it has done its job. This could be a problem for session management if you specifically don't want that job being done twice in a session. Now you could hack around that, but I'd really rather see a neat solution. Is there one?

Help with jsp and javaBean in eclipse/Tomcat

Hi,
I am new to JSP and JavaBean. I am going through tutorial for a jsp page that uses a javaBean. I am using eclipse to create jsp page and the java bean.
My eclipse project "Date" has five package as under:-
1. Deployment Descriptor
2. Java Resources: src
3. build
4. WebContent
I have my data.jsp page in WebContent/WEB-INF/ folder. When I just run date.jsp in a browser as: http://localhost:8080/Date/date.jsp, it gets launched into the browser correctly. But when I add a JavaBean "TimeFormatterBean.java" in the Java Resources:src folder and use it in date.jsp page, I get errors as under:-
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 5 in the jsp file: /date.jsp

     <jsp:getProperty name="formatter" property="name"/>
     </p>
</body>
</html>I can see "TimeFormatterBean.class" in build/classes folder.
If anyone could please help me out with this, it would be very helpful
Thanks a lot!

You probably should place TimeFormatterBean inside a package, or maybe you could try importing it , even if it�s in the default package, with something like this <%@ page import="TimeFormatterBean" %> at the top

Help with JSP and LUCENE -

I downloaded Lucene (apache product) and put the jar files in the /webapps/lucene/WEB-INF/lib directory. I created a simple jsp file:
test.jsp
<%@ page import = "org.apache.lucene.*" %>
<%@ page import = "java.io.*" %>
<%@ page import = "java.util.Date" %>
Test
<%
Date start = new Date();
IndexWriter writer = new IndexWriter("index", new StandardAnalyzer(), true);

I don't know what is wrong. The classpath I thought was set correctly to my jar files, but that doesn't seem to work. There isn't much documention on how to use JSP with Lucene. I got the basic examples they have working, but can't seem to get it working when I create my own stuff.
PLEASE HELP!!!!!!!!!!!!!!!!!

Apparently I have to set the classpath EACH TIME.
How can I program this into the jsp so I don't have to do that? I thought that it would automatically find it if it was in the correct directory.
Also I am following the directions of lucene but it won't search correctly. Nothing gets returned in the example search. What gives???

Making a Quiz in Flash. Need help with input time

Hi Flash Community,
I'm making currently a quiz using Flash Pro CS5. What I want to implent is a time bar which will load once the bar is loaded it will go to the next frame.
So what I need is first a timer which will start immediately when the user sees the question and I need a time bar which will indicate how far the timing is. So let's say you have 30 seconds to answer the quiz. When the timer is at 15 seconds the bar will be at half.
Something like this http://www.google.nl/imgres?imgurl=http://theportablegamer.com/wp-content/uploads/2009/10/ question.jpg&imgrefurl=http://theportablegamer.com/tag/quizquizquiz/&usg=__xsykgRnehmB9P97 gg3W9tAx2Dfg=&h=320&w=480&sz=57&hl=nl&start=0&sig2=tdKlW2Iv6zHo3THsHwdVpQ&zoom=1&tbnid=ToM bL22o-D7BOM:&tbnh=107&tbnw=160&ei=aiz7TcGONI2gOpic0b4E&prev=/search%3Fq%3Dquiz%2Binterface %26um%3D1%26hl%3Dnl%26sa%3DN%26biw%3D1902%26bih%3D909%26tbm%3Disch&um=1&itbs=1&iact=rc&dur =317&page=1&ndsp=68&ved=1t:429,r:13,s:0&tx=100&ty=47
Could anyone help me with this? How do I need to do this?
Thanks!

Help with jsp session validation

i've build up a page that only users wil 'administrator' as the session is variable can access. if they don't they will be directed to the login page.
However, I'm getting a null pointer exception.
my code is as follows:
<%@ page import="java.io.*"%>
<%
     if (session.getAttribute("id").equals(null) || !(session.getAttribute("id").equals("administrator")))
          response.sendRedirect("adminlogin.htm");
%>

any pros please help? i know it's something to do with my jsp session validation. thanks in advance.

one more thing, with regrads to the solution evnafets provided. I tried it out on all my pages that requires administrator rights and found that the code only redirects when it's not expecting any parameters. Else, it just display an error message there. Is there a way around this? Or I should let let my end user suffer?

Help with a timer?

Here's what I want to do:
When the mouse is pressed (on mouseDown), set sprite.BlendLevel to a value (I know how to do this).
When the mouse is lifted, begin a timer. If the mouse has not been pressed after 30 seconds, the sprite.BlendLevel value changes.
(I want this timer to reset every time the mouse enters a mouseUp state. HOWEVER, it should not reset every frame update - ONLY when the mouse is first lifted.)
Basically, I'm making it so a touch screen app fades if it hasn't been touched for 30 seconds (with just one big sprite overlaying it at varying blend levels). That's all.
I can't wrap my mind around timers, so that's why I'm having problems with figuring this out.
Thanks for any help you can offer. I truly appreciate it. I feel like there aren't enough people out there working with Director anymore, so finding help like this is valuable.

Type this in your Message window, and then press Enter:
go movie "http://nonlinear.openspark.com/tips/sprites/TimerFade.dir"
Is that the sort of thing that you are looking for? It's currently set to trigger after 5 seconds, but you could use...
the timeOutLength = 1800
... in line 13 of the Fade Behavior, to make it wait 30 seconds (1800 = 30 seconds * 60 ticks/second) before it triggers.

Need serious help with JSP + JDBC/Database connection

Hey all,
I have to build an assignment using JSP pages. I am still pretty new and only learning through trial and error. I understand a bit now, and I have managed to get a bit done for it.
I am having the most trouble with a Login Screen. The requirements are that the a form in a webpage has Username/Number and Password, the user clicks Login, and thats about it. The values for the username/number and password NEED to come from the database and I cannot manage to do this. The thing I have done is basically hardcode the values into the SQL statement in the .jsp file. This works, but only for that one user.
I need it so it checks the username/number and password entered by the user, checks the database to see if they are in it, and if so, give access. I seriously am stuck and have no idea on what to do.
I dont even know if I have made these JSP pages correct for starters, I can send them out if someone is willing to look/help.
I have setup 3 other forms required for the assignment and they are reading data from the db and displaying within tables, I need to do this with non-hardcoded values aswell. Im pretty sure I need to use for example 'SELECT .... FROM .... WHERE username= +usrnm' (a variable instead of username="john" , this is hardcoded), I just CANNOT figure out how to go about it.
Its hard to explain through here so I hope I gave enough info. A friend of mine gave some psuedocode i should use to make it, it seems ok to follow, its just I do not know enough to do it. He suggested:
get the username and pass from the env vars
open the db
make an sql (eg SELECT user, pass FROM users WHERE user = envuser)
index.jsp points to login.jsp
login.jsp get the vars you put into index.jsp
opened the db
is the query returns nothing - then the user is wrong
OR if the passwords dont match
- redirect back to index.jsp
if it does match
- set up a session
- redirect to mainmenu.jsp
Anyway, thanks for any help you can give.
-Aaron

Hi,
Try this... it may help you...
mainMenu.jsp
<html>
<body>
<form method="POST" action="login.jsp">
Username: <input type="text" name="cust_no">
<p>
Password: <input type="password" name="password">
<p>
<input type="submit" value="LOGIN">
</form>
</body>
</html>
login.jsp
<%@ page import="java.io.*, java.sql.*"%>
<html>
<body>
<%
try {
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection connection = DriverManager.getConnection("jdbc:odbc:rocky");
Statement statement = connection.createStatement();
String query = "SELECT cust_no, password FROM customers WHERE cust_no='";
query += request.getParameter("cust_no") + "' AND password='";
query += request.getParameter("password") + "';";
ResultSet resSum = statement.executeQuery(query);
if (request.getParameter("cust_no").equalsIgnoreCase(resSum.getString("cust_no") && request.getParameter("password").equalsIgnoreCase(resSum.getString("password"))
%>
<h2>You are logged in!</h2>
<%
else
%>
<h2>You better check your username and password!</h2>
<%
}catch (ClassNotFoundException cnfe){
System.err.println(cnfe);
}catch (SQLException ex ){
System.err.println( ex);
}catch (Exception er){
er.printStackTrace();
%>
</body>
</html>
I didn't check the code that I wrote. So you may have to fix some part of it. Also this may not be the best solution, but it will help you to understand the process easily.
The more efficient method is to check whether the result set returned from the database is null or not.... I hope you got the idea... Good luck!
