Html- jsp- servlet to retrieve data from DB

hi there, i'm a newbie of jsp programming and I'm trying to develop a simple application in order to retrieve some data from a database table. Then I want to display it.
I read lots of examples but all of them used sql queries or java code into the jsp file. Actually I would like to respect the MVC structure as much as I can.
The final thing shoul be like this:
-type in a name into the search box implemented in the html file
-the html file then calls the jsp wich get the typed in value and pass it to the servlet
-the servlet which connects to DB and makes an SQL query using the typed in value, then send the result to the jsp
-finally the jsp displays the result (in this case I'm trying to use displaytag (displaytag.sourceforge.net)).
The code must still have to be checked for unuseful stuff but it compiles and this is enough by now.
Here it is:
cerca_agenzie.html
<html>
<head>
    <title>Cerca un'Agenzia</title>
</head>
<body bgcolor="white">
<i>     Inserisci il nome dell'agenzia di cui si richiedono le informazioni o parte di esso e poi clicca sul pulsante "Cerca"</i>
    <form action="info_agenzie.jsp" method="get">
      <table>
          <td>Nome Agenzia:</td>
          <td><input type="text" name="cerca">
          </td>
        <tr>
          <td colspan=2><input type="submit" value="cerca"></td>

These values are from a form MStatus1.jsp which are
retrieved by a javabean named fileuploadbean:And you are sure those values are actually set? Besides, accessing fields by name strings strikes me as a little bit odd and un-OOish. But oh well..
The name strings are the names of the controls on the MStatus1.jsp file.
The controls are having their values from database which are no doubt visible on the MStatus1.jsp page.
on MStatus1.jsp page i have a button on whose click the servlet is called which uses fileuploadbean to retrieve the values from MStatus1.jsp page.

How to retrieve data from a jsp page

I have created a page with some text boxes, file, submit button. In my Ist jsp, i am dynamically add Text boxes and File (for Uploading).
In the 2nd jsp, i am used Jakarata FileUpload API. I am able to retrieve all data and files except that value of dynamicall added text boxes. That is, I cannot retrieve data from dynamically added text boxes.
Using Jakarata FileUpload API, i can retrieve values of form data using
getString() method.
I want to know that there is any way or method for retrieving form data values into String Array.

Use parseRequest(request) to get the file information as you already are doing. However, I dont know how you can use request.getParameter("textField1") to get the other fields from the page. My work-around is as follows:
Change your submit button to an ordinary button and add an onClick event to it. Then in the javascript function that supports the onClick, add the textField1 as follows:
<form name="fileUploadForm" method="post" action="someAction" (((more code code here)))))
function submitButtonClick(){
document.fileUploadForm.action=
document.fileUploadForm.action+
"?textField1="+document.fileUploadForm.textField1.value"+
"&textField2="+document.fileUploadForm.textField2.value"+
"&textField3="+document.fileUploadForm.textField3.value";
document.fileUploadForm.submit();
As you can see in the above code, I append the textField1 name/value pair to the end of the action. Now in the server, you can use getParameter("textField1");

How to increase speed while retrieving data from tableand showing it in pop

Hi,
In one form ,I have used f9 key to retrieve data from table in oracle database . i.e. in any input field in my form, once I press f9 key, it execute JavaScript windows. Open command.
In that command, I called the servlet which retrieves nearly 7000 rows data from table and then it dispatch request to another jsp page which shows the related data in tabular form. The data may contain nearly 7000-8000 rows.
So when I press the f9 keys it takes around 10-12 second to open the page.
Is there any ways to open this pop up windows within 2-3 second once I hit the f9 keys.
Here with I am attaching hole code for servlet and jsp page.
Any suggestion is highly appreciated.
Thanks and Regards

First of all you will have to apply paging to show data in tables. and retrieve only those sets of data which are required. You will defnitely need to do lot of code for that. but i am hopeful, you will get some thing on net.
Second thing you can do is use AJAX. It will show your popup and will keep on loading data simultaneously. You can use JQuery and many others for that.

How to Retrieve data from database into another form ?

Good Day!
Am currently new at JSP. I've been studying it for awhile and still getting the hang of it. We are working on a project.
Editing a given data. We have to retrieve the given data and post it to another form "Editing form".
Since we can retrieve data using JSP but how are we going to post it to another form? I mean how are we going to transfer data from one form to another?
Can anyone help me with codes please..

The client is a web browser.
The client submits a request (click a link, visit a form)
The server gets to respond to this
- look at request parameters from the client
- access database
- produce resulting html page
- send page back to client.
The standard pattern is to retrieve data from the database in java code, and then load that data into a bean.
You then make that bean available as an attribute
It is then available for use in your JSP - either <jsp:useBean> tag or using ${ELexpressions}
All you can pass from the client to the server is request parameters - which are always strings.
Draw a picture of where the information is, and the information flows. Very rarely does it go directly from one "form" to another.

Hi,
To retrieve data from list in your provider-hosted app using SharePoint Client Object Model(CSOM), you can follow the links below for a quick start:

Retrieve data from a dynamic page via loadURL

Hello.
I would like to ask you how it is possible to retrieve data
from a dynamic page (asp classic in my case) using the loadURL
method.
I would like to create an html authentication form (with
username and password fields). The loadURL method should call an
asp page and then pass to the usual function 'DoIfSucceded' the
results of the elaboration.
Of course I'm going to have a switch in the function in order
to make different actions depending from the results of the asp
page (authentication succeded or failed).
I had a look to the examples at this page:
Adobe
samples
Is there anyone who can explain clearly how the results data
must be written by the asp page and how the success function can
retrieve them ?
I thank you in advance for your help.

loadURL() uses the the XMLHttpRequest Object so if the
content you return is XML, you have 2 choices for accessing your
data. You can either access it as a text string via the
XMLHttpRequest object's responseText property, or as a DOM document
via the XMLHttpRequest object's responseXML property:
function MySuccessCallback(req)
// If my data is XML, I can access the data that was sent
from the server
// as DOM elements via the XMLHttpRequest's responseXML
property.
var xmlDOM = req.xhRequest.responseXML;
// OR, you can access the data sent back from the server as
text via
// the XMLHttpRequest object's responseText property.
var xmlAsAString = req.xhRequest.responseText;
var req = Spry.Utils.loadURL("GET",
"/app/book.php?id=1&code=54321", true, MySuccessCallback);
If your serverside script wants to use some other format as a
response like JSON or plain text, then you can only access the data
as text via the responseText property.

What are the different ways of retrieving data from Oracle8i

What are the different ways of retrieving data from Oracle8i
into my HTML page ?
Is it JDBC and ODBC ?
Is there any other way ?
null

Methods I tried,
Applet using SQLJ/JDBC with JDBC drivers thin or Oci8,
Oracle Web Publishing Assistant,
HTP/HTF PL/SQL packages (if you have OAS 4.0)
Webserver Generator of Designer 2000 (if you have OAS 4.0)

Failed to retrieve data from the database when adding jdbc datasource

I'm having problems adding some tables to the selected tables list using the database expert.
I get the error messages "Failed to retrieve data from the database" followed by "Unknown Database Connection Error".
I thought it may be a permissions issue as it only affects some tables, but I can access the same tables fine using the same user through Oracle SQL Developer.
The database is Oracle 10g Express Editions
Crystal version is 12.0.0.683
Running on Windows XP
Any suggestions would be much appreciated.
