JSP :: How To Send Array In JavaScript To Servlet
Aug 20, 2014
In my jsp, I have a table with some file paths with this I have to get the file and send it to server. I am able to read the file name, size and file as binary using files of javascript. But after that I need to send those files by storing in a byte array to servlet which I am not able to that. Is there any way I can send that. My requirement is I need to upload those files to server side.

I have an arraylist in my servlet which i need to pass to jsp as a response for a javascript call. This is an arraylist of DTOs. There are 24 DTO objects in the list. The DTO has an int variable and a HashMap. And i need to pass this into the javascript code in my jsp page. Do i use json? Do i send the entire list as a json object or should i iterate through the arraylist (from servlet) and serialize all the DTOs and pass that to the jsp?

I made an application and i can send the message/notification to all loggedin users immediately. But the problem is that i am unable to send notifications to a specific user; as an example facebook chat.I am using Servlets 3.0, Spring MVC 3.0, GSon and AJAX Jquery.
Here is my code:
web.xml
<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
[code]....

I'm creating a web applicaion. for that i want to create a registration page. and this registration details have to be stored in the database.
I'm getting the below error while trying to send the data ...
The requested resource (/cmd/InsertRegtodb) is not available.
Here cmd is project name and InsertRegtodb is servlet name.
Actually the servlet is present is the mentioned address. but it is not connecting to it
There is one more servlet in the same folder and which is accessible from another jsp. But this servlet is not accessible even though i have used same code as it is used for the servlet which worked for me previously...

I'm using JBoss 7.1.1.Final. I'm writing a Spring 3.1.1.RELEASE web application and have a massive amount (~5MB) of text output to send to the browser. I would like the browser to display the output as it is generated, but right now, the browser only displays everything after the servlet's doGet method completes. Here's my method …
@RequestMapping(value = "/mymethod", method = RequestMethod.GET)
public void refreshOrders(final HttpServletResponse response) throws IOException
{
execute(response, myWorker);
}
private void execute(final HttpServletResponse response,
[Code] ....
I set my buffer size to be 1K but that doesn't do anything.

I can now call the DB on the query I want and return results. What I know want to do is build an array of the data, forward it to the JSP page and display the bits individually.
So THis is the Servlet I havce:
package com.journaldev.jdbc.datasource;
import java.awt.List;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
[code]...
I think It is to do either with the way I am adding the values to User or its the forward:
getServletConfig().getServletContext().getRequestDispatcher("/test.jsp").forward(request, response);

I'm trying to pass an integer array,
int[] fibSequence;
From my Fibonacci servlet to a jsp page called "result" but when I pass the array in the redirect I get the following output:
[[I@63cf2179]
I figured out that this is because the array is being converted to string before it is passed over and then converted again on the jsp page.
How I can pass the array over and print the contents, ie an array of integers?
This is how I'm sending the array in the result page:
resp.sendRedirect(("result.jsp?fibSequence=" + fibSequence));
And this is how its being retrieved and printed on the result.jsp page:
<%String[] fibSequence = request.getParameterValues("fibSequence");%>
<input type="text" name="fibNum" value="<%=java.util.Arrays.deepToString(fibSequence)%>" size="40px" style="font-size:30pt;height:60px">

I have a java application in which when starting it a map is opened and a screen is captured. The capturing is in certain time interval. I want to enable the user to change the interval for the automatic capturing the map. I placed a text box in a JPanel. I want to pass the value which was entered in it to the html page which opens a Google map. Since I am new in java programming, I found that I can do it by using applets. I made an applet, and tried to call it in the html file. But now instead of opening the map file in a browser, it opens very quickly only black window.
Here is my applet:
package cege.ui;
import java.applet.Applet;
import java.io.IOException;
import cege.ui.GuiMain;
public class AppletTInterval extends Applet {
private int TimeInterval=0;
[Code] .....
And the code in the html file where I try to call the applet, i.e. to pass the value which is returned by the applet is:
<script src=
<!--"https://www.java.com/js/deployJava.js"></script>
<script>
var attributes = { id:'AppletTInterval',
code:'cege.ui.AppletTInterval', width:1, height:1} ;
var parameters = { jnlp_href: 'AppletTInterval.jnlp'} ;
[Code] .....
Can I use this way to pass a value from the java class file (from the JTextField into the html file?

I am taking Python this semester. Our teacher wants us to convert Python to JavaScript without really explaining how or/and expecting us to be familiar with it already.Python Program I have is pretty simple - it prompts you to enter your first and last name and end your DNA string, "CAG" repeats are counted by another function and the result is passed to function that identified weather you may have huntington's decease or not.
<body>
<p>Enter First Name: <input type="text" size="25" id="firstname" value="">
<p>Enter Last Name: <input type="text" size="25" id="lastname" value="">
<p>Enter DNA: <input type="text" size="25" id="DNA" value="" >
<p><button onclick="alertt(f,l,d,c,p)" style="background-color:pink"><b>PRESS TO FIND OUT RESULT</b></button></p>
<script>
[code]...
When I run it there is an issue with countCAG and prediction functions :( I would run each one individually in JS console and I get Undefined, or InvalidString I read that I am supposed to use var in front of each variable, unlike in Python where you just assign variable a value without any add-ons in the front. But JS console seems to recognize both ways of assigning, however var smth=0 immediately evaluates to Undefined, and smth=0, gives me 0...

I have a problem with a JavaScript application on Safari 6 and 7. The application updates a smartcard on a website, through a JAVA applet using JavaScript requests.
There is no problem with other browsers. On Safari , randomly (1 smartcard's update on 10), the javascript completely freezes in the middle of an update (on a random card).
After 5 minutes exactly, the javascript resumes, and 2 behaviors happens : the update wether continues or stops completely.
We investigated a lot about this problem , at network and memory level. We use a lot of "setTimeOut" function (approximately 1100 times), and read that setTimeOut could cause problems with memory management on Safari.
Does setTimeOut can freeze safari ?

I'm creating a SOAP Client with JS, this is my first time with webServices and I must have several mistakes in my code.
The poit is, with my code, I cant take acces to the WebService, but I don't know how to access to the methods inside. So the webservice gives me the following response:
<h1>Version</h1>
<p>Hi there, this is an AXIS service!</p>
<i>Perhaps there will be a form for invoking the service here...</i>
Instead of the correct XML for the method I'm calling.
This is the code of my SOAP client:
<html>
<script type="text/javascript">
function run(){
var objXMLHttpRequest = new XMLHttpRequest();
objXMLHttpRequest.open("GET", "http://localhost:8080/CrunchifyWS/services/Version?wdsl/", true);
objXMLHttpRequest.onreadystatechange = function () {
//alert(objXMLHttpRequest.readyState+" "+ objXMLHttpRequest.status);
[code]....
I think that te mistake should be in the XML part, but, as I said, this is my first time and I don't know what I'm doing.
When I try to do POST instead of GET I have this reposnse:
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="w3.org/2001/XMLSchema"; xmlns:xsi="w3.org/2001/XMLSchema-instance">; <soapenv:Body> <soapenv:Fault> <faultcode xmlns:ns1="xml.apache.org/axis/">ns1:Client.NoSOAPAction</…; <faultstring>no SOAPAction header!</faultstring> <detail> <ns2:hostname xmlns:ns2="xml.apache.org/axis/">WebServices-PC</…; </detail> </soapenv:Fault> </soapenv:Body> </soapenv:Envelope>

I've got a banner that displays on the web page and users can close it out by clicking an "X" button in its corner. Once it's closed, we track for that session that it remains closed, so a cookie gets set. I'd like subsequent requests to the server to be aware of this cookie so that the banner code is just not included in subsequent responses. (Sidebar: earlier I was just detecting the cookie after page load and then hiding the banner but it creates a lag where the banner is visible then suddenly pops away, making for poor user experience.)
I expect that even though Javascript set the cookie it would then show up in HttpServletRequest.getCookies() call, but there's actually a lot of cookies visible in Chrome Developer Tools on the client of my page that don't show up in .getCookies(). Does the HttpServletResponse.addCookie need called at some point first for the cookie to be passed back and forth to server?

I am trying to find a way to make a URL that is used during a background AJAX call to log a user out more flexible. Currently, I have it as a static value, as below:
var logoutURLTest = "https://test.myorg.com/cas/logout";
...AJAX stuff that uses the logoutURLTtest variable...
However, if that URL was to change for any reason, I would have to modify one or more JSPs if they were affected, instead of just changing it at a single point in the Spring environment context. It would be more desirable to expose the value using a property placeholder; however, the Spring documentation isn't exactly clear on whether this is possible.
