HTML form validation in JEditorPane

Hi,
I'm trying to add some browser capabilities to my java application.
For example, imaging that i would like to run the google website inside my java application in a JEditorPane.
I managed to let the JEditorPane handle the links, but I don't know how it is possible to let the textfield and submitbutton work properly.
Especialy when the form-method of the site is POST.
In short I would like a small browser as a component in my application.
I can't find a way to do this.
All ideas are welcome :-)
Thanks very much

Take a look at this thread, it explains how you can get the elements of the HTML document inside the JEditorPane.

How to retrieve data from the HTML form in the JEditorPane?

I could quite easily use JEditorPane to render and display a simple HTML file.
My HTML looks like this:
<html>
<head>
<title> simple form</title>
</head>
<body bgcolor="cccccc">
<center><h1>SURVEY THING</h1>
</center>
<form id="survey">
<p>1.Type something in.</p>
<textarea cols=25 rows=8>
</textarea>
<BR>
<p>2.Pick ONLY one.</p>
<input type="radio" name="thing" value="0" Checked> NO choice <BR>
<input type="radio" name="thing" value="1"> First choice <BR>
<input type="radio" name="thing" value="2"> Second choice
<BR>
<p>3.Pick all you like.</p>
<input type="checkbox" name="stuff" value="A"> A <BR>
<input type="checkbox" name="stuff" value="B"> B <BR>
<input type="checkbox" name="stuff" value="C"> C <BR>
<input type="submit" value="give data">
<input type="reset" value="do clensing">
</form>
</body>
</html>
It gets diplayed fine and I can type in text, select radio buttons (they behave mutualy-exclusive,
as they should) and check checkboxes.
The problem I have is with retrieving the values which were entered into the form.
If I, after editing, try to write the html to the file using HTMLWriter,
it records the changes I made into the textarea, however all the radio and checkbox selections are lost.
Maybe the problem is that when I enter the values I do not use any methods like
insertBeforeStart and so on, but I believe I shouldn't need to use them to populate a form.
Especially I never change the structure of the HTML.
Also, when I try to traverse the Element tree and see the input elements attributes,
I can never see a change in the entered values. However it is probably b/c I am traversing through
the model and the changes are in the view (just a guess.)
Anyway, if anybody could direct me onto the right path: how to retrieve the values typed in the form,
or if it is possible at all in the JEditorPane, I would greatly appreciate.
thanks

PS. I have seen the answer to a similar question posted some time last year. However, I am trying
to find a soultion which allows forms/surveys to be built by people who have no java and only basic
html knwledge. And Axualize way is probably a little bit too "high-tech."

Maybe helpful for u.

Render html form & send forms's input values as params via HTTP POST

Hello,
I'm using appache commons http client to send HTTP post queries to a given url and receive HTTP response then process it.
one of the requirements of my Application is the following: one of these HTTP Post requests is supposed to return an HTML form with different html types (text filed, text area etc..) that i will need to display in my swing application. one important requirement is that i can't know in advance what the html form field types will be.. it depends on a given parameters that my application send as part of HTTP Post method (using apache http client).
I Longly searched for a simple solution to this problem . There are many solutions but each one has it's limitations :
1-i can render the html form inside a JEditorPane .but how can I collect the user entered data inside JEditorPane ? i'm not sure this swing component offers the capability to detect its html contents and more it will be difficult to know what are the values entered by user inside html form rendered by JEditorPane.
2-are there any Java Embedded browsers that offer some API to enable me detect the html form fields ,capture the data entered by user inside the html form ?
3-the solution i currently opted for is : parse html & convert html form to swing dialog. currently this solution i use works well but the cost of implementing it is high : it involves difficult parsing logic. this makes me worried .I'm not sure if i'm now using the right & easiest solution.
I need some advice on What is the simplest and clean solution to render a html form & yet be able to collect user entered inputs & send the user input values as params via java HTTP POST request ?

In my opinion, your actual solution is what you need to do. You're trying to "merge" two different kinds of view. Actually, the "easiest" way may be: if you have your data to display, you decide to show it on html or swing.Yes i believe that my current solution may be the unique one for my special requirements. when doing research about this problem i found a multitude of java libraries to convert xml to swing (ex: www.swixml.org) .However i was surprised there are no java libraries to convert HTML forms to swing dialogs -as far as i know-. this is a bit strange. The Limitation is that the developers of the server API are not Java guys and are reluctant to use an xml format that i can easily convert to swing . probably they have their own reasons as they might be using the HTML Response for some other server side work. So I was obliged to deal with an HTML stream that i need to display in my client application and process its data. in my opinion the only way to do this is by developing a HTML form to swing converter package. that's what i did now. i was only worried if i'm complicating things and if there are some easier solutions to this issue.

How can an applet retrieve the values of a HTML form shown in a JEditorPane

Hi,
I'm doing an applet that contains a JTree and a JEditorPane
among other components. Each node of the JTree represents some
information that is stored in a database, and whenever a JTree
node is selected, this information is recovered and shown in
the JEditorPane with a html form. To make the html form,
the applet calls a servlet, which retrieves the information of
the node selected from the database. This information is stored
like a XML string, and using XSLT, the servlet sends the html
form to the applet, which shows it in the JEditorPane.
My problem is that I don't know how I can recover new values
that a user of the application can introduce in the input fields
of the html form. I need to recover this new values and send them
to another servlet which store the information in the database.
If someone could help me I'd be very pleased.

URGENT: JEditorPane (a Java Browser) displaying HTML form

Hi,
I am using JEditorPane to display the wb pages but geeting problem as
I don't get any kind of event when I click on the HTML form SUBMIT button though it does work but didn't allow me to get the URL of the new page that I got after hitting this SUBMIT button..
I searched the whole net and it seems to me that lot of people got this problem...
As I need this for my project please HELP me as soon as possible.

This may be too late for you (hopefully not), but I had the same problem a little while ago and just figured out how to fix it. Basically, you need to examine the Element structure of the html yourself and manually handle the form, as far as I can tell. There are several ways to display a URL in a JEditorPane, but the most straight-forward (JEditorPane.setPage(URL url)) doesn't actually store the Element structure anywhere accessible. Here's the code to load the page:
JEditorPane contents;
HTMLEditorKit kit = new HTMLEditorKit();
HTMLDocument htmlDoc = new HTMLDocument();
contents.setEditorKit(kit);
contents.setDocument(htmlDoc);
URL url = new URL("http://blahblahblah.com");
contents.read(url.openStream(), htmlDoc);Now that you have the page loaded correctly, you can access to the Elements within. You can use htmlDoc.getDefaultRootElement() to get the root and then iterate recursively through all the child Elements, checking out the Attributes of each. This will look for the submit button and add a listener to it for you:
private void parseElements(Element elem) {
    AttributeSet atts = elem.getAttributes();
    //If this is the submit button, add a listener:
         Object model = atts.getAttribute(StyleConstants.ModelAttribute);
         Object type = atts.getAttribute(HTML.Attribute.TYPE);
         if ((type != null) && (type.equals("submit"))) {
             DefaultButtonModel btn = (DefaultButtonModel) model;
             btn.addActionListener(new ActionListener() {
                 public void actionPerformed(ActionEvent event) {
                     System.out.println("Yay!");
    //Recurse
    for (int i = 0; i < elem.getElementCount(); i++)
         parseElements(elem.getElement(i));
}Of course, printing out "Yay!" is not really very helpful. When you're parsing through the Elements, check for the attribute StyleContsants.ModelAttribute. If that exists, you can cast it to the correct type of Model (see the documentation for HTMLDocument.HTMLReader.FormAction for information about what types of models to expect from what types of HTML elements) and store it until the "submit" button is pressed. Then all you have to do is get all the data from the models, format it and submit it to the action URL in either a "get" or a "post." The action URL is stored, in Java 1.3, in the HTML.Tag.Form attribute of one of the Elements (I don't remember which one). Getting that attribute returns a SimpleAttributeSet, and you get the HTML.Attribute.Action out of that. In Java 1.4 it's easier to find, you just have to look for the HTML.Attribure.Action attribute in one of the Elements.
Why isn't this all automatically done for you? I don't know. Good luck.

JEditorPane can't handle POST from HTML form?

I posted this before but i never got an answer so i'll try again :-)
Im running a tomcat server were i have a jsp script that uploads files to the server. What i need to do to is to use a regular java application for the rest of the "project" im working on.
And i can get the JSP page to be displayed properly using JEditorPane but i cant get the html FORM POST in the JSP to execute... i dont know if theres some limits in JEditorPane or if im just using the wrong type of approach on this one.
This is the server
http://chilly-schrimp.kicks-ass.org/uploadbean/SimpleUpload.jsp
(only works if my computer is turned on)
Heres the code:
=======================================================================
import javax.swing.*;
import javax.swing.event.*;
import java.io.*;
public class JSPtest {
public static void main(String[] args) {
JEditorPane pane = null;
try {
pane = new JEditorPane("http://chilly-schrimp.kicks-ass.org/uploadbean/SimpleUpload.jsp");
catch (IOException ex) {
ex.printStackTrace(System.err);
System.exit(1);
pane.setEditable(false);
// Add a hyperlink listener.
final JEditorPane finalPane = pane;
pane.addHyperlinkListener(new HyperlinkListener() {
public void hyperlinkUpdate(HyperlinkEvent ev) {
try {
if (ev.getEventType() == HyperlinkEvent.EventType.ACTIVATED)
finalPane.setPage(ev.getURL());
} catch (IOException ex) { ex.printStackTrace(System.err); }
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(new JScrollPane(finalPane));
frame.setSize(350,400);
frame.setVisible(true);

any suggestions??

I am using request.getParameter(passed variable name)
to pass data from HTML form to JSP with no problem.
WHen I try to pass data from HTML form of
multipart/form-dta type to JSP as following:
< form enctype="multipart/form-data" name="theForm"
method="post"
ACTION="http://titan.ssd.loral.com:7778/ifs/jsp-bin/if
-cts/stringsecond.jsp">
The passed value is null. Why?because the jsp most likely does not handling of POST parameters like this.
How can I pass data successfully from this form to
JSP?jsp's are not meant to read such amounts of data. this (= uploading) is a typical task for a specialized servlet. there you have full control over input and output. if you need to, you can still forward to a jsp after processing in the servlet.
How can I pass data from JavaScript to JSP???? i'm not sure what exactly you mean. normally you put it into an url and submit it.

Validating HTML form generated by servlet

Hi, folks. I have a dynamic html form generated by a servlet class. Once user fills up the form and submits it, i have another servlet does the form validation. My question is how can i reload the generated html form with error messages when user's inputs failed validation?
I am not able to use JavaScript pop-up windows for doing validation cause the page will be displayed on PDA and cell phone as well. Any help is greatly appreciated.

Could you combine the servlets.
I'm not sure but then you may be able to have the generator servlet in the doGet method and the validator in the doPost method. (don't quote me on this)
If you combine the servlets you have access to the original data (the form), that way if any validation errors occur you can repost the form with their entered data and an error message.

Why is HTML showing in the form validation message?

Here is what is showing when I use server side form validation.
<ul><li>You must select a location </li></ul> Go <a href="javascript:history.back()">back</a> and correct the problem.
Obviously, the HTML tags are not supposed to be shown. What's going on here? I just upgraded to CF9 on Linux and this started happening. Any ideas?

It's a standard CF server-side form validation and looks like this on the form:
<input type="hidden" name="somefield_required" value="some field is a required field">
When they submit the form (and didn't enter something for somefield), the automatic message comes up. The formatting of the message is messed up on CF9. I've been using this type of server-side validation for years (probably since CF5) and have never seen this problem before.
Actually, this works fine on another server (CF 9,0,0,251028) but on CF 9,0,1,274733 it is having this issue. Both are running CF Enterprise on Linux.
Error message is supposed to look like this:
Form entries are incomplete or invalid.
some field is a required field
Go back and correct the problem.
The messed up message looks like this:
Form entries are incomplete or invalid.
<ul><li>some field is a required field</li></ul> Go <a href="javascript:history.back()">back</a> and correct the problem.

HTML 5 Contact Form "Placeholder" instead of label makes form validation not work

Hi,
I am trying to implement a HTML 5 contact form which uses a "placeholder" within the field instead of a label. But now the form validation does not work.
The site is at http://www.partnerrealestate.ch/avenuedefrance23/index.html and it is not using any workflows from BC as the person receiving it is an external person and the process does not require a workflow.
Would appreciate any input into this.
Kindest Regards,
corina

There is no label on input fields. The form does not work because you have edited the names. BC needs the ID and names to be as it is issue when you create the form so it knows what to use for the validation and what information to pass into the database.
So where you have edited these, you need to restore those.
You have some invalid html on some input's as well one has input="" inside of it when rendered so that is not right.
It is not to do with placeholder use. So fix up your HTML errors, correct the name and ID changes and it will work fine.

HTML 5 FORM VALIDATION

Hi,
I'm trying to validate forms in my website with Safari but it seems not to recognize the attribute required (<input type="text" name="name" required />)
Can anyone help me?
Thanks.

Carolyn,
I have the same question regarding safari not recognizing "required" in the html5 form validation. I checked out the link you provided, but didn't find an answer.
Can you help?

Pete:
Remove the name attributes from all input elements defined by the pl/sql process. For example
<input name="company" type="Text" size="30"/> should be replaced by <input type="Text" size="30"/> or <input name="f01" type="Text" size="30"/>
The APEX accept process recognises a predefined set of HTML form input names. Any input with a name not from this set will cause the accept process to fail. f01 through f50 are valid names for the accept procedure.

Is there a way to bypass the form Validation

I'm getting really upset with the Coldfusion built-in form validation for any HTML formfield ending by _date , _required, _time and so on...
My application proposes to the users to create some Properties for an object and later on to modify the values for all these properties.
I've got a piece of code building dynamically some form fields named just like the properties (by a simple cfloop on a DB query getting the property list).
And a registering page to records the new value in the DB.
But it crashes onto the classical "
Form entries are incomplete or invalid.
I can't control what the users set as property name (one of them was Checklist_required).
Is there any way to prevent this error by disabling this auto validation ?
(I'd like to avoid having to rename any field dynamically created and rename any forms variables before registering them on the DB : it's just NO WAY for me to rename the properties created by the users)

Fober1, that's not how it works. It's pretty much the ultimate example of the disjoint between how HTML forms work and how the naive CFML Cfform / cfinput design wished they work.
When a request is being processed by the coldfusion server, it just looks at the list of FORM (POST) variable names (whether it came from cfform or not; URL/GET params are exempt), and for those with certain suffixes (_date, _required, etc.), and it assumes their existence is intended to request validation another field without that suffix. It doesn't actually know or care whether form submission, nor the HTML rendered in the user's browser, actually came from "cfform" or "cfinput". The composition of the request that comes in (when a user clicks on "submit", or a hacker uses any tool imaginable) is out of the server's hands. The cfform code is not used during form submission processing, because the receiving template (the form action="this_one.cfm") doesn't even have to be the same template that has the cfform in it. There could be multiple conflicting cfforms directing users to request the same template on a single site, with or without the validation, even without considering what a whole other person might decide to send to your server.
The fact that it can work as intended for a typical user is irrelevant, because the purpose of validation is to deal with the atypical situation. A malicious or merely mischievous user that wanted to circumvent the validation would simply modify a copy of the page to leave out the "validation request" fields. For the developer to truly validate the input, additional code must be written, making the feature not only inadequate, but a complete waste of time. There absolutely should be a way to disable it at worst; Ideally, it would be taken out of coldfusion completely. It's not only useless, it's a security risk, wooing programmers to write code that doesn't do what they think it does.
The error message it gives isn't so great, either, and it's a pity that it can't show more than one validation message at a time, either. If more than one input is invalid, you could end up going through one round after another of submit + back button.
edit: I forgot to add the other important reason that this feature should never have existed: It is a nuisance to everyone else who doesn't want to use it at all, too! Those suffixes simply couldn't have been a worse choice, colliding with probably thousands of peoples' variable names. Why not "*_cfval_date" "*_cfval_time" etc?

Using Javascript form validation in WordPress - Firefox issues

I have been struggling for a while to get javascript to validate a WordPress based HTML form which uses radio buttons. I finally came up with a solution with was a bit long-winded but worked - at least in IE and Chrome - however, it doesn't work in Firefox (which suggests my code is a bit sloppy). I think my radio button reference is the issue. Can anyone help with what I have done wrong - apart from use an inefficient approach for validation :-)?
A simplified version of my form:
<script>
function validateForm()
var aa=document.forms["personalise"]["motivation"]["1a"];
var ab=document.forms["personalise"]["motivation"]["1b"];
var ac=document.forms["personalise"]["motivation"]["1c"];
var ad=document.forms["personalise"]["motivation"]["1d"];
var ae=document.forms["personalise"]["motivation"]["1e"];
if (!(aa.checked == true || ab.checked == true || ac.checked == true || ad.checked == true || ae.checked == true))
alert("Question 1 must be completed");
return false;
</script>
<form name="personalise" action="insertdatatest.php" onsubmit="return validateForm()" method="post">
1. Are you seriously planning to quit </b>:  
<input id="1a" type="Radio" title="" name="motivation" value="1" /> Within the next 2 weeks
<input id="1b" type="Radio" title="" name="motivation" value="2" /> Within the next 30 days
<input id="1c" type="Radio" title="" name="motivation" value="3" /> Within the next 3 months
<input id="1d" type="Radio" title="" name="motivation" value="4" /> No, I am not currently planning to quit
<input id="1e" type="Radio" title="" name="motivation" value="5" /> I have already quit
<input type="submit" value = "Submit">
</form>

Thanks for your support,
This will partly solve the issue I think. Now, the validation is indeed only done for the first form. But I need to save data twice when entering data in the second grid. When checking the error console in mozilla I see following error:
Error: grid[r] is undefined
Which is reffering to:
if ((grid[r] [1] != missing) ||(grid[r][2] != missing) || (grid[r][3] != missing))
When I save again, the data will be saved without this error.
Is there a way to exclude the second grid in the if Statement?
Regards,
Erik

Cannot view HTML form input entry in Firefox.

I have a basic html form embedded in a Wordpress footer widget to collect email addresses and I can place the cursor in the input field (there is only one input field) but I cannot see what I'm typing. If I enter an invalid email address (without being able to see what I'm typing) and hit the submit button I can see on the error page (since a valid email address is required) what I originally typed. The URL is askdrkyle.com and the form is on the left hand side of the footer.
I do not have this problem in any other browser.
Thanks!

I figured it out. I had adjusted the height of the input element to a height that did not work well with the padding. Once I removed the height style and adjusted the padding I got the size I wanted and can see the text as it should be.
Thanks for your help forgottengods!

Submiting HTML Forms with JavaFX Webview

I've long been searching for a good web robot framework. And I also need a gui for my robot.
So w/ the advent of JAVAFX Webengine it seemed my needs have been met finally. Specially because on the webview tutorial here , Alla Redko says: "+It supports user interaction such as navigating links *and submitting HTML forms*+".
But after looking at the api it doesn't seem that webengine supports submiting forms, only loading pages w/ the load() method. I guess I could populate the form fields and submit them w/ executeScript() but that's just sloppy.
Is there a way to actually submit forms w/ webengine? Are there plans to implement this feature, analogous to the load() method?
Thanks,
JC

Yea, as I mentioned in the first post, I could do all that w/ JS but it's just sloppy, since I'm using Java language, not JS.
The finding certain fields part is easy w/ the Document model and xpath, it's the populating the fields and submiting the form along w/ its hidden input fields that is the missing part.
Does anyone know if these things are planned for the future of Webview/Webengine?You can already do this in Java today using the existing APIs if you so wished.

}Personally, I think using JavaScript via engine.executeScript calls in combination with jquery might be a less messy solution (as I don't like writing against the raw dom apis), but I understand that there are valid reasons why you might prefer to use a Java only solution.
