Newbie to JSP needs help

I'm running tomcat and apache and basic servlets work fine, however when I try the usebean tag; I get an error message "CLASS not found". The class object is in the same directory as the servlet?
Any suggestions?

Re: Embedding Applet which takes dynamic input, into JSP | Need help

Hi All,
We are into a project in Oracle Portal Server where in we want to embed a result of a standalone application(Which is applet) in JSP.
This standalone application generates applet based on the input it gets from the current application's database.
If it was static we could have used jsp:plugin but, it fails in our case!
We are clueless as to how to embed an applet which will pick up the data dynamically.
Can anyone of you help me in this regard?
Thanks & Regards
Arthi

You can call an applet's public methods from JavaScript.
(And even the other way around, using JSObject).

I am a beginner in Labview and need help with multi-device synchronization.

I am using a VI I found in order to continuously acquire and write voltage. The next phase is to somehow synchronize this with a linear platform and am wondering if there are any tutorials on how to do this out there, or if anyone could give just general advice. I'm not necessarily asking for explicit details on the code but rather where I would be able to improve my skills in a way that would help with this project. Thank you in advance.

Hi riraheta,
Are you using daq? Can you tell me more about this linear platform which you want to synchronize? What operation do you plan to synchronize?
There are some examples online which has to do in synchronizing devices, depends on what you're planning to synchronize. The following are the few I have found.
Links (Presuming that you're using DAQ devices):

JSP with useBean beginner problems need help

I start to learn JSP and now I am facing a problem which cannot be solved for a whole day.
I make a simple JSP and want to use a my defined class to make some logic outside JSP file. It can be built by "ant build".
But there is always an error-message when I see through browser. Also, I have already "ant deploy" to copy all classes in WEB-INF/classes/...
Besides, my tomcat can run JSP without importing external class or javaBean.
Please help. I really have no idea. Thanks.

Works fine for me, copied and pasted exactly.
Try recompiling your java class again, to make sure it is valid.
Check that the class file is copied into the correct place by your ant build.
Should be WEB-INF/classes/Test/Beans/Converter.class

Need help w/ JSP formating a page.

Ok. I need to make the following code work. I think it needs help w/ formating is all. Below is the JSP page I would like it in as well as where I think the code should go. Not shure how to get it to display the output though.
var fullSessionName;
Function startHODSession(sessionName) {
var i = document.HODApplet.startSession(sessionName);
if (i == 0) {
fullSessionName = sessionName + document.HODApplet.getSessionID();
I need to run that part of code and display the output on a webpage. Any help would be awosme as I am lost w/ JSP more of a vb kind of guy. but learning quickly. Thanks for any help or advice.
Thanks
My JSP file:
<%--

<input type="submit" value="Push IT" name="id"/>
</body>
</html>

Great catch on the aplet and maybe that is where I am going wrong. So let me back up a little and maybe you can get me out of my bind.
Basically what I want for a test app is: a little text box w/ a button. type in an number and click the button.
the button will then send the info to a terminal emulator. (ibm host on demand)
So that is what the 3 include statements where for. I got that from the API example.
so what I really need the page to do is print the list of connections.
so I need to get the latest session ID:
var fullSessionName;
Function startHODSession(sessionName) {
var i = document.HODApplet.startSession(sessionName);
if (i == 0) {
fullSessionName = sessionName + document.HODApplet.getSessionID();
Then run:
public int sendKeys1 (String text)
The string being what was put in the box.
for right now i do not need error checking and i know the screen will be on the right spot to accpet the input.
so if there is a better way to make it work using an applet....Im all for it.
any ideas would be great.
thanks

Beginning Programmer needs help - JSP and databases?

1. I have never used JSP before, but have been given an assignment to create a webpage to query a database. The database is in Access. Does anyone have a snipet of code in JSP that will query an MS Access database. Is there a function that I can use and pass it an SQL (select statement) and have it return a list of results.
-OR-
If there is a way for JSP to transform the MS Access database into a text file that would be good also.
2. Has anyone created a search functionaly using JSP (or know of a tool) that can search documents, PDF files, HTML files, etc.
Thank you for any help!

hi , there is no big deal in JSPs, Servlets, EJBs e.t.c its olnly a matter of committing time and getting urself familar and in areas where you have problems this forum is a nice place for you to share all what u have.
to start with i will give you some sites where you can start learning jsps, servlets, ejbs and the rest.
1) http://java.sun.com/j2ee -> look for JSPs , Servlets, EJB, JavaBeans e.t.c
2) http://www.jspinsider.com
3) http://www.coreservlets.com
4) http://www.jakarta.apache.com (download tomcat for your container)
for databases u can use this code snippet but u will have to read more about databases to be able to chagne some things in this snipper such as your database username, password , url and the rest.
     <%@page import="java.sql.*" %>
     try
        Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
        Connection con = DriverManager.getConnection ("jdbc:odbc:test_dsn", "sa", "");
     Statement stat = con.createStatement ();
     ResultSet res = stat.executeQuery("select * from authors");
     while (res.next())
          //process the results of this query
     catch (Exception e)
        //process this also
%>
You will need to become farmilar with the java programming language and also database conventions so you have a proper understanding.
study those db codes and modify to suit your needs.
buzz on me in case you are stuck.

Novice Programmer Needs To Learn JSP

Hi All,
I am an experienced HTML programmer and my current employer would like me to learn JSP, JavaScript, and Java. They would prefer I learn JSP first.
I have no programming experience beyond HTML. What is the best way for me to learn JSP? Can I learn through books or will I need to take a class?
I appreciate any and all advice.
- Rob

Maybe someone else will disagree with me, but from my experience your management does not have a clue.
JSPs may look like more fancy HTML pages, but in fact the use of them by an application server (such as Tomcat) causes them to be translated into Java code and they become servlets. So, you cannot do serious JSP work without being aware of what is going on in wrinting Java Servlets.
JavaScript, although the name starts with "Java" is a distinct language, used pretty much only in browsers as a way to have smarter action implemented in the browser. JavaScript shares a tantalizing amount of Java's syntax, but they are different.
For example, if we consider a form to be used by someone to prepare information to send to a web site, with JavaScript, you can do validation before the data is sent to the server and put up a message to the user with no network traffic required. With logic only in Java code on the server, you will need to send the data to the server to do validation, and then send back a rejection notice asking for the user to recreate the information.
The ugly truth (in my opinion) is that to be a good writer of Java-ish things to be shown in a browser, you need to know HTML, JavaScript, Java, and Java Servlets. (Pretty soon you will need to deal with database stuff.)
JSPs can make some tasks easier, but you need to know what is really going on or you can make errors at a high rate of speed.
JSPs are not required. You could write code on the server to create a stream of html output that is a combination of standard blocks of html code and content from other sources (usually databases). With JSPs however, you can write blocks of html and java code and the process of compiling a JSP turns it into Java code that generates the stream of html output wiith intermixed data. It is easier to do maintenance on a JSP than on a plain servlet.
For example, if you are doing a page that is a "shopping cart" for an e-commerce site, you can have the standard html lines to create the <table> and header rows. Then, you switch into Java, get the data, and loop through the entries. For each item in the list of contents you output a row of the html table. When you are through looping through the data, you exit the java code and have a plain old html ending of the table.
Does this help?

Beginner: Need Help : Label Frame

Beginner: Need Help : Label Frame
Hi everyone,
I am trying to find a way to get my menu bar working. Little info, I am a beginner in Flash just learned the essential DVD from Adobe.
My menu bar has the following:
(About Us) (Services) (Quality) (Projects) (Contact Us)
Each page will have a motion shape tween and slide the page down.
I have type in this actions :
stop();
import flash.events.MouseEvent;
//---aboutus Button Timeline change---\\
aboutus_btn.addEventListener(MouseEvent.CLICK, aboutusClick);
function aboutusClick(event:MouseEvent):void{
gotoAndPlay("aboutus");
//---services Button Timeline change---\\
services_btn.addEventListener(MouseEvent.CLICK, servicesClick);
function servicesClick(event:MouseEvent):void{
gotoAndPlay("services");
//---quality Button Timeline change---\\
quality_btn.addEventListener(MouseEvent.CLICK, qualityClick);
function qualityClick(event:MouseEvent):void{
gotoAndPlay("quality");
//---projects Button Timeline change---\\
projects_btn.addEventListener(MouseEvent.CLICK, projectsClick);
function projectsClick(event:MouseEvent):void{
gotoAndPlay("projects");
//---contactus Button Timeline change---\\
contactus_btn.addEventListener(MouseEvent.CLICK, contactusClick);
function contactusClick(event:MouseEvent):void{
gotoAndPlay("contactus");
This actions only works when I click to the next labels but doesn't work when I want to click back to the previous labels. For example, if I click onto (About Us) to (Services) and (Services) to (Quality) and (Quality) to Projects and (Projects) to (Contact Us)... it all works. If I then click from (Contact Us) back to (Projects) or even any previous buttons... it does NOT work??
Anyone? Please help!

This is my timeline structure. The code for the action frame is in hi-lite in yellow.
Is this clear enough?
I also tried rewriting the action like below, but still have the same problem.
stop();
aboutus_btn.addEventListener(MouseEvent.CLICK, onaboutusClick, false, 0, true);
services_btn.addEventListener(MouseEvent.CLICK, onservicesClick, false, 0, true);
quality_btn.addEventListener(MouseEvent.CLICK, onqualityClick, false, 0, true);
projects_btn.addEventListener(MouseEvent.CLICK, onprojectsClick, false, 0, true);
contactus_btn.addEventListener(MouseEvent.CLICK, oncontactusClick, false, 0, true);
function onaboutusClick(evt:MouseEvent):void {
gotoAndPlay("aboutus");
function onservicesClick(evt:MouseEvent):void {
gotoAndPlay("services");
function onqualityClick(evt:MouseEvent):void {
gotoAndPlay("quality");
function onprojectsClick(evt:MouseEvent):void {
gotoAndPlay("projects");
function oncontactusClick(evt:MouseEvent):void {
gotoAndPlay("contactus");

Raw Beginner need help with Adobe Photoshop CS2

I am reading Photoshop CS2 for digital photographers by Scott Kelby. I am looking at pg 55 if any one has this book and would like to visually see what I am about to describe. I own Adobe Photoshop CS2 software. After bringing up Adobe bride RAW on my PC, I then see all the settings, Exposure, Shadows, Brightness, Contrast, and Saturation.. Located directly above all of these settings is Auto and Default which you can click on and adjust all settings at the same time. If you don't like what you see you click on Default to go back to the original, you can then make your adjustments individually. In my CS2 book there is an Auto box you can check or un-check beside each setting, Exposure, Shadows, Brightness, and Contrast. My question is how do I get the Auto box beside each setting so I can simply put a check in that box and preview changes individually instead of the Auto and Default on top which changes every setting at the same time? I hope this make since to you, if not I will try to explain again.

Thank you Ramon for your help. I will just be happy with what I have, which works fine but I thought it might be better for me to have the individual Auto check box for each setting. Thank you for the tip to double-click the sliders to reset it to default, it works in CS2 also:) Actually this gives me more control and works out great now that I think about it. I am sure there are more handy little tips I should know about but don't because I am a beginner in learning RAW. Hopefully I'll stumble across a book or some thing over the internet that will help me with my learning curve.
