Servlets :: HTML Body Onload Not Working In Chrome
Mar 12, 2015
I 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.
I am trying to use three cookies in a servlet to store the background and foreground color and text size but my code is not working for some reason. When I run the servlet I get an IndexOutOfBounds exception and in my code is says my cookies are not ever used, when they should be to store the variables?
I am making a n-body simulation. For some reason, when I have two bodies orbiting each other and I add a third body, the two initial bodies stop orbiting each other.
EXAMPLE:
[URL]- earth is orbiting the sun, when I add mars,[URL] earth AND mars does not orbit the sun and both travel in a straight line. Almost as the forces are not being computed at all on the body. How can this be?
Here is the relevant code:
public void update(float deltaTime){ for(int i=0; i<bodies.size();i++){ resetForces(); bodies.get(i).update((float)(deltaTime / Math.pow(10,9))*timeScale); lastTime = System.nanoTime(); //sets the forces for all bodies for(int n=0; n<bodies.size();n++){
1. Does a GET HTTP request contain a request body? If yes what is contained in it? Are the request headers also part of the request body? 2. Is it possible to send a byte array as part of the GET request in its body? 3. Is there a size limitation on the data that can be sent via a GET request?
My problem is my teacher told me that i have to add a radiobutton on html. According to radiobutton servlet has to choose write parameters on DB or File. And he wants me to add a method to do this work.
1)Get Parameters 2)Choose to write DB or File according to parameters 3)if it is DB create connection and do writing process 4)if it is file create file and do writing process.
Second piece of code should be removed. İnstead of this i have to use a single method. But i don't know how to do this(not writing code). Should i use another servlet or a class...
I have a very simple HTML form with a textField for a name, and add button to add the name to a MySQL database, and a sort button to sort the names in the database and display them. I almost have it working, however when I hit the "sort" button; I get the message that appears after a user clicks the add button along with the sorted list of names. It looks like this:
Please go back and add a name or sort. Bill Jones David G Debbie Downer Jane Doe Joe Smith John Doe Mike Jones Paul Smith Susan Jones
What I have to change on my code to make just the list show up by itself when the user clicks sort?
Is it possible to get the list/ values in html/jsp from servlet?
I have a table inside an html/jsp page and when the user clicks a button I need to refresh the whole page with some additional text message.
Currently what I am doing is that I am using a java bean for the jsp page that contains a list of values inside the table then store it in session but I think there is a better way without storing it in session.
I tried using request.getParameter() but it only returns string.
I am having an issue with retrieving "grouped" data from HTML form to servlet. I will describe the scenario below.
In companies, they record the salary of the employees once a month.When they record it, they do not do it by visiting each an every employees personal "profile" (or whatever according to the system). Instead what they do is apply the salaries of all of them in one page.
To do the above thing they prefer excel like tabular sheets. Now, I have a html form, where the form content is a table. One row is dedicated to a one employee.
As you can see, I have wrapped every row with a `<tbody>`. The `value` attribute of the `<tbody>` will contain the employee id. Once the form is submitted, the below servlet will capture it.
What I was trying is get the `value` attribute of `<tbody>` (so I can identify the id of the employee) and get the data inside that `<tbody>`. However this didn't work, because I ended up with `NullpointerException` because it failed to read the `<tbody>` value.
So, how can I pass the data from table to servlet where it can clearly understand that one row is representing data belong to a one employee? If this is not the way to do it, I am also open for other methods.
In one jsp page, I submit a form with a message body with following html code (which is store in "MsgBody" in my request)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
[code]....
But when I submit my form, I received in my servlet a parameter "MsgBody" without several tag like <html>/<body> ... do you know this behavior, by default tag are delete ?
I need to get the html in string when i hit the hit the jsp in servlets basically i need to put the output of jsp in pdf file when i hit one link i need to download that data in pdf file. I am using itextpdf.
//Get the output stream for writing PDF object OutputStream outStream=pResponse.getOutputStream(); ByteArrayOutputStream baosPDF = new ByteArrayOutputStream();

I need to convert the sample download.jsp to html so that i can parse
i have one html page ,inside html radio button and 3 textboxes and one submit button ->action->SampleServlet.java-> from here again come back to html page with checked radio buttton value and text box value. I dont want to click back button in this case, html page to servlet->here i have to call back to my html page with checked radio button and text box value .
I tried response.redirect(original.html)-->i cant able to display checked radio button and textbox value also tried requestdispatcher forward/include,html page comes newly from starting but i dont want it,i want to view in html page with checked radio button and text box value.
I 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?
I use Chrome rather than IE. Recently I got an error message when I tried to deposit a check online.
It said that I needed up get a newer version of Java than 6.10, so I downloaded 7u51.
When I tried to deposit the check again, Chrome asked if I wanted to run the app, and I said yes, but that took me back to the download link again.
I spent almost an hour with my bank experts, but they were unable to solve the problem.
When we tried it on Internet Explorer, it worked fine.
Later, I discovered that on the Java Control Panel under the Default Browser for Java, it has only IE and Mozilla, with the IE being checked and greyed out.
I'm assuming that's why the problems on Chrome, even though up until a few days ago, I was able to deposit checks using Chrome-Java.

in my web.xml my session time out is working but not fully working in my ui i use tiles , i have 5 clickable side panels i try to set timeout for 1 minute or 10 minutes for testing after the time is timeout this what happen working refresh the page after time out = working ,directed me into log in page which is correct.i have 5 clickable side panel in my page after timeout when i click the first 2 in side panel tabs it directed me into log in page which is also correct not working after the timeout when i navigate the page i click the other 3 side panels i can still navigate into the page but when i click the first 2 side panel it directed to log in page w/c is correct but can still navigate the page the other 3 side panels

I 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?
I have a jsf form which has a drop down. When I select any value in drop down it shows related details. When I use chrome browser, and I press back space key it comes back to the page, it keeps the value selected which was selected earlier, but in the firefox, IE it keeps the zero index selected. The same code is not working for chrome browser.
I would like the zero index to be selected in the drop down in previous page in chrome browser also when back space key is pressed...
I have a requirement. I got a JSF page(parent page). When a button(say SEND EMAIL) is pressed, an email window (OUTLOOK) will be displayed as a popup. I have to populate whatever the text data of parent page as the body of the mail.
I am using mailto method : eg :
Here is my code: ============== FacesContext context = FacesContext.getCurrentInstance(); HttpServletRequest origRequest = (HttpServletRequest) context.getExternalContext().getRequest(); context.getExternalContext().redirect(String.format("mailto:"+mailTo+"?subject=" + subject +"&body=" + body + "&cc="+mailCc+""));
till here it is fine..
My problem is body part is not getting breaks. I have tried , , , <br>, <br></br> etc.. what ever stuff i found in google..
E.g. my email body looks like below.. it consists of url link also.
My current URL is URL....The context rootpath is URL....In my current URL page, I upload a CSV file. This page has two buttons-- ok and Cancel and these buttons are what I'm having trouble with ( I will come to that part in a short while). The relevant JSP part is as follows.
<html:form action="importEmployee?method=save" method="POST" styleId="importEmployee" enctype="multipart/form-data"> ....... some headers and title bar and stuff... and then as follows. <div class="contentSection"> <table border="0" class="formTable"> <html:hidden property = "selectedSet" /> <tr>
[code]...
So, if I click on cancel in the second URLpage (URL...), I go back to the first URLpage, i.e to URL...But this part behaves differently in Firefox and in Chrome browsers.In Chrome, if I click on cancel in the second page, I can still see the uploaded file name( the hidden property in the first JSP is the file name ) in the first page. And if I click on ok, I can do the processing again as was done by clicking ok the first time on the first page.However when I run my application in a Firefox browser, if I click on cancel in the second page, the uploaded file name says 'no file selected' in the first page. Hence to import Employees again, I need to upload a new/same CSV file again.
I don't want the file to be present in the first page when I click on cancel in the second page even when I run my application in Chrome. Yes, I require the file name to be a hidden property. This is because depending on the data in the file, different kind of processings are done and some of them require to take additional inputs from user on another page and a third page does the processing. So the file name should be passed on to the form but I don't want the user to upload the file again.
However in the event the user clicks on cancel, I don't want the file name to be retained in the first page. But this isn't happening.So I have two questions. Why is the behaviour different in Chrome and in Firefox and is there a way I can correct the way it behaves in chrome?
i am calling a method of my applet from within the javascript. My code works fine with all browsers except CHROME.i get this exception in browser = "Uncaught TypeError: Object #<HTMLObjectElement> has no method 'loadComplete' mainControl.js:6". i called this method on the "onload" of <body> tag.
I have to write a program that calculates and displays a person's body mass index (BMI). The BMI is often used to determine whether a person with sedentary lifestyle is overweight or underweight for his or her height. A person's BMI is calaculated with the following formula:
BMI = Weight X 703/Height^2
where weight is measured in pounds and height is measured in inches. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person's weight is considered optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered underweight. If the BMI value is greater than 25, the person is considered overweight.However I can't seem to get rid of these errors:
----jGRASP exec: javac BMI.java BMI.java:28: error: cannot find symbol Scanner keyboard = new Scanner(System.in); ^ symbol: class Scanner location: class BMI BMI.java:28: error: cannot find symbol
