Sending Email Hangs Program
Jun 17, 2013At first, oracle change this site a lot. I logged into this site after a long time and I was amazed to see the new changes. Moving onto the the question.
I am developing a spring mvc web application. The problem is when I send email, let say to more than 4 person, the program hangs for a while. Some friend told me to use thread pool to solve this. What is the general practice for handling this kind of situation?

View Replies View RelatedServlets :: Sending A Form Using JavaScript
Oct 8, 2014I just want to to ask how can I send a form to a servlet using javascript?
Here's my form:
<form id="movieForm" class="form-signin" action="addnewmovie" method="POST"
enctype="multipart/form-data">
<h1 class="text-center movie-title">Add New Movie</h1>
<div class="row">
<div class="col-md-12">
<input id="movieId" type="text" class="input-hide form-control"

[Code] ....
This button will responsible for sending:
<button id="add-new-movie"
class="button-position btn btn-primary btn-block"
type="submit" onClick="submitForm();">Add Movie</button>
Note that I include file uploading in the form.
Servlets :: Sending A List Fetch From Database To JSP
Oct 6, 2014I am trying to display a list fetched from DB in a JSP.
My servlet mapping is:
<servlet>
<description></description>
<display-name>DocumentsServlet</display-name>
<servlet-name>DocumentsServlet</servlet-name>
<servlet-class>com.xyz.servlet.DocumentsServlet</servlet-class>
[Code] ...
The code in the servlet is:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
List<Doc> docs = null;
Connection con = null;
[Code] ....
The code in JSP is:
<%
List<WWDoc> completedDocsList = (List)request.getAttribute("completedDocs");
System.out.println("In JSP == "+completedDocsList.size());
%>
The request is not coming back to the JSP page.
If I change the servlet and have "request.getRequestDispatcher("/pages/ViewCompletedWWDocs.jsp").forward(request, response);" un commented, I get exception "java.lang.IllegalStateException: Cannot forward a response that is already committed".
Sending To All Vs Sending To One Person In Server / Client Program
Apr 17, 2014I have two programs that I'll post below, one is a Server and the other is a Client. The ChatServer runs once and many clients can run ChatClient from separate computers and talk together in their GUI's. The the client program comes with two buttons, one that's simulates the sending of a message to a single user ; "Send Message To User", and one that just generally sends a message ; "Send Message To All". Although now the Clients on the server seem to be able to selectively send messages to an individual by giving the recipient name, all the clients can see that message, which is not exact what I am aiming for. What I am going for is having the "Send Message To User" button click to send a message to the named user without all other users seeing the message.
The Server Program Code
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;
import java.util.ArrayList;
[Code] ....
Now I have tried thing like having various input output streams and trying to connect those, but no luck. Tried fiddling with having the names arraylist directing the messages to one client versus all but that did not work out either. How I what I would need to do to go about doing this?
Servlets :: Multipart Form Data - Sending Additional Data?
Feb 21, 2014I am using apache-commons-fileupload to get file from client to the server.(using JSP and Servlet).
JSP/HTML
<form method="POST" action="GetFile" enctype="multipart/form-data">
<input type="file" name="datafile">
<input type="text" name="text1">
<input type="submit" value="Next">
</form>
Servlet: GetFile
System.out.println(request.getParameter("text1"));
I am able to upload the file to the server, but I am not able to get the value of text1 in the servlet (I am getting null value of text1 in the servlet), I need this textfield in the form to submit some additional information while uploading it to the server.
--> Is enctype="multipart/form-data" option of form doesn't allow other form data to be submited? if it doesn't allow it then what are the other options I have to send this additional textfield to the server.
--> Or is there any other problem in my code?
Servlets :: Checkbox Not Working Right
Jan 22, 2014I am trying to finish this servlet that adds a new course to my courses display. im using a check box so the user can pick what the prerequisite are for the new course they want to add. so if they check cs201 , it will add cs201 as a prerequisite for that new course.
for some reason my checkbox will only add the first checkbox that is clicked. like if i add a subject , and click the check boxs for cs203 , cs202, and cs201. it will only grab cs201 and add it to my course display. it wont grab all 3. how can i grab the other info thats checked?
package cs320Homework1.servlet;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;

Code For OCR Scanner Not Working As Applet
May 18, 2014I need to make a scanner (that has a built in ocr) output some content to a browser. I haven't gotten to the browser yet, but the code works when I run it as an application. With the scanner, I received Java code that makes the scanner take a picture, then read from it and output it back to the console. I added a few lines to make it an applet:
Java Code:
import gx.*;
import pr.*;
import java.applet.*;
public class DocScan extends Applet {
/**
*
*/
private static final long serialVersionUID = 1L;
[Code] .....
I am using Eclipse as an IDE. Right now my goal is to simply make the scanner "flash". I know that the output is to the console and I will not see anything from it in an applet, but it should still flash.
When I run this code as an application, it works. The scanner takes a picture and then it outputs what it has read to the console.
When I run this code as an Applet, the applet starts and does nothing. It just stays there with no errors of any kind (at least that's what Eclipse is showing me).
I read that I should allow the applet access, so I edited:
Java Code:
c:program filesjavajre8libsecurityjava.policy mh_sh_highlight_all('java');
And added this at the end:
Java Code:
grant {
permission java.security.AllPermission;
}; mh_sh_highlight_all('java');
Which should allow applets full access. However, there is no change - the applet still launches and does nothing. Why is the code not working when I run it as an applet?

Pythagorean Theorem Program - Code Isn't Working When Written In OOP Style
Feb 11, 2014I'm attempting to make a simple Pythagorean Theorem program (A squared + B squared = C squared) but am running into problems when I write it as object oriented. The darn thing works when written as a simple process, but that isn't Java now is it? Here's the simple:
public class PythagoreanTheorem extends ConsoleProgram {
public void run() {
println ("Finding C from A and B.");
double a1 = readDouble("Input A: ");
double b1 = readDouble("Input B: ");
double aSq = (a1*a1);
double bSq = (b1*b1);
double cSq = (aSq + bSq);
double c = Math.sqrt(cSq);
println ("C = " + c);

Servlets :: Shopping Cart Session Is Not Working Properly
Jan 4, 2015I am adding my shopping cart in session like bellow in servlet
HttpSession session = request.getSession();
session.setMaxInactiveInterval(60*30); // 30 minutes
if (session.getAttribute("cart") == null){
session.setAttribute("cart", new ShoppingCart());
}
cart = session.getAttribute("cart");
I seems if more than one person accesses it from server, if they items in the shopping cart, all the product is added to a single session. I mean if i added 4 items first and other person adds 2 items, second person sees 6 products in his cart. Where am I going wrong?
Servlets :: HTML Body Onload Not Working In Chrome
Mar 12, 2015I have written sample web application with servlets and jsp. As per the below code the action url should be executed automatically according to the "onload". I have written this below code in one of my servlet, The below "onload" form hits the path in action only in Firefox and IE but not in Chrome(41.0.2272.74 beta-m (64-bit)).I have seen the link [Chrome - <body onload=“”> is not working ][1] , I have my below code in the end of servelt. there is nothing to execute after this code in the servlet.
out.write("<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
");
out.write("<html><body onload="alert('alert has been fired');document.forms[0].submit()">
");
out.write("<form method="POST" action="" + actionUrl + "">
[Code] ....
Is there any reserved key words of chrome in the above action url? If I execute this code in the html format, it is working in chrome. but if it is from servlet, alert() is not running.
Servlets :: Dojo Progressbar Not Working Properly With Commons FileUpload
Sep 22, 2014I have been trying different examples on showing progress bar for file upload progress for couple of days.
Some of the different example were using libraries like Dojo,jQuery and just using plain AJAX with iframe method.
But unfortunately, however i try i'm not able to show the progressbar thingy at all although the upload part is working good.
Following is the example with Dojo[dojo-release-1.0.3]
I'm using Servlet 2.5,commons fileupload libs, TomEE-plus-1.7. 0 & ant for building tool in ubuntu 12.04 as the platform with firefox 32.
Here is the code (as it was in the site)
build.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="upldEx6" basedir="." default="clean">
<!-- Properties start-->
[Code]....
If i choose a file of size 68MB, on page load the progressbar is seen but stays at 0% all the time even after submttting the form.
On debugging, cant find error/bug here.
P.S This code can be seen CodeGuru: FileUpload Example

email.append("It is my great pleasure to");

Scanning Text File For Email Addresses
Mar 2, 2014Write a program that scans a text file for possible e-mail addresses. Addresses look like this:
someone@somewhere.net
Read tokens from the input file one by one using hasNext() and next(). With the default delimiters of Scanner, an entire e-mail address will be returned as one token. Examine each token using the indexOf() method of String. If a token contains an at sign @ followed some characters later by a period, regard it as a possible e-mail address and write it to the output file.
Programs such as this scan through web pages looking for e-mail addresses that become the targets of spam. Because of this, many web pages contain disguised e-mail addresses that can't easily be automatically extracted and above that is says to modify a program from our chapter which is this:
import java.util.Scanner;
import java.io.*;
class NamedFileInOut {
public static void main (String[] args) throws IOException {
int num, square;
[Code] ....
This is the first time hasnext() and next() have been introduced to me, so whereas scan.nextInt() looks for integers, does hasNext() looks for strings or characters? the wording in the exercise text is confusing to me. so basically i should create a text file with a ton of strings and within that jumble of text, stick a few email addresses; then when the program asks the user for the input file name, use that text file's name correct? pretty sure i have it up to that point, but using the indexOf() is what i'm having trouble wrapping my head around. do i look for the index of "@" and "."? i could conceptually see how i could say if the indexOf(".") is three spaces before the end then i know it's a .com or .net or .org or whatever. but how would i use indexOf("@") when the "user name" AND the "provider" (i.e. @yahoo or @google or @whatever) have an infinite number of lengths? we haven't had literally any discussion on input/output in classes so i am totally green to this.
