How can I embed an DOCTYPE HTML Form from Adobe Forms central into a responsive html5 page?
-Luis

Hi,
You can embed the form on your website, but you need to make sure that javascript has been enabled in the browser. You need to copy the embed code and add it into your HTML code. If you would like FormsCentral to generate embeded HTML form without using javascript, you may post a feature request and vote it. Hope it helps! Thanks!

Create HTML Form from PDF Form

Does anyone know of a quick way to create an HTML Form from an existing PDF Form?
Thanks everyone!

From ID you can export to XHTML which is indeed consumed by DW but not via Acrobat...
So, can I import a PDF form into ID?
When I meant was - InDesign can export to XHTML
Acrobat cannot
Indeed, it would be great if forms could be created as ID objects and then exported to a PDF form but not yet (all fingers and toes crossed for CS5/CS6)

Html form - java applet

Hi friends
I have an html form with an editable textfield on it. Next to it is an Java Applet with an Button on it. If you klick the button, a Popup aperars where the textfield can be modified. There is also an OK Button on this Popup. If you klick the Button, I want that the value of my string will be plased into the html form.
If anyone knows how that works. Please help me.
thanks kendiman

Sweet, I was wondering how to do that.
So if one was to design a menu using java, the external Java Script can access the public variables within the applets?
So if we had
public class applet extends Applet {
   public int test;
   public applet() {
      test = 6;
}then the javascript command
document.applet.test
would return a 6?
Do I have this correctly?

Problems calling a html form from a different page

Hi,
I'm working on a logon for a website. I have a html page and a jsp page that contains the login function. I want to call the login form after the user presses submit. But I'm having problems calling the form from the html page.
Any help appreciated.
Here is my html page:
<form method="POST" action="login.jsp">
<table>
<tr>
<td>
<div align="center">
<b>UserName:</b>
<input name="user_name" type="text" class="input" id="username" maxlength="18">
<b>Password:</b></font>
<input type="password" name="password" class="input" maxlength="18">
</input>
<input type="button" border="0" value="Login" width="30" height="20">
</input>
My jsp page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
<body bgcolor = "#E5E8EF">
<script language="javascript">
function login(form) {
alert("hello");
if (form.username.value=="joe") {
if (form.password.value=="bloggs") {
location="success.html"
} else {
alert("Invalid Password")
} else { alert("Invalid UserID")
//-->
</script>
</body>
</html>

So your intention is that the JS function would be invoked somehow?
Are you aware that Javascript is a completely different language from Java/JSP/JSTL?

How to fill out POST HTML forms from my Java Application?

Hi -
I am writing a little Java GUI program that will allow a user to fill out data from the GUI and then submit that data. When they submit the data (two text fields) I want to take the two text fields and submit them via the POST form method of a HTML document over the web.
Here is what I got so far:
host = new URL("http", "<my_address>", web port, "/query.html");
            InputStream in = host.openStream();
            BufferedInputStream bufIn = new BufferedInputStream(in);
            for (;;)
                int data = bufIn.read();
                // Check for end of file
                if (data == -1)
                    break;
                else
                    System.out.print ( (char) data);
            }What that code does is makes a URL, opens a stream, and reads the HTML source of the file at the specified URL. There is a form that submits data via the POST method, and I would like to know how to write data to specific forms and specific input types of that form.
Then, I'd like to be able to read the response I get after submitting the form.
Is this possible?
Thanks,

Here is how one of my e-books go about Posting
I tryied in one of my projects and it works ok
(Tricks of the Java Programming Gurus)
There's another reason you may want to manipulate a URLConnection object directly: You may want to post data to a URL, rather than just fetching a document. Web browsers do this with data from online forms, and your applets might use the same mechanism to return data to the server after giving the user a chance to supply information.
As of this writing, posting is only supported to HTTP URLs. This interface will likely be enhanced in the future-the HTTP protocol supports two ways of sending data to a URL ("post" and "put"), while FTP, for example, supports only one. Currently, the Java library sidesteps the issue, supporting just one method ("post"). Eventually, some mechanism will be needed to enable applets to exert more control over how URLConnection objects are used for output.
To prepare a URL for output, you first create the URL object just as you would if you were retrieving a document. Then, after gaining access to the URLConnection object, you indicate that you intend to use the connection for output using the setDoOutput method:
URL gather = new URL("http://www.foo.com/cgi-bin/gather.cgi");
URLConnection c = gather.openConnection();
c.setDoOutput(true); Once you finish the preparation, you can get the output stream for the connection, write your data to it, and you're done:
DataOutputStream out = new DataOutputStream(c.getOutputStream());
out.writeBytes("name=Bloggs%2C+Joe+David&favoritecolor=blue");
out.close();
//MY COMMENT
//This part can be improved using the URLEncoder
//******************************************************You might be wondering why the data in the example looks so ugly. That's a good question, and the answer has to do with the limitation mentioned previously: Using URL objects for output is only supported for the HTTP protocol. To be more accurate, version 1.0 of the Java library really only supports output-mode URL objects for posting forms data using HTTP.
For mostly historical reasons, HTTP forms data is returned to the server in an encoded format, where spaces are changed to plus signs (+), line delimiters to ampersands (&), and various other "special" characters are changed to three-letter escape sequences. The original data for the previous example, before encoding, was the following:
name=Bloggs, Joe David
favoritecolor=blue If you know enough about HTTP that you are curious about the details of what actually gets sent to the HTTP server, here's a transcript of what might be sent to www.foo.com if the example code listed previously were compiled into an application and executed:
POST /cgi-bin/gather.cgi HTTP/1.0
User-Agent: Java1.0
Referer: http://www.foo.com/cgi-bin/gather.cgi
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Content-type: application/x-www-form-urlencoded
Content-length: 43name=Bloggs%2C+Joe+David&favoritecolor=blue
Java takes care of building and sending all those protocol headers for you, including the Content-length header, which it calculates automatically. The reason you currently can send only forms data is that the Java library assumes that's all you will want to send. When you use an HTTP URL object for output, the Java library always labels the data you send as encoded form data.
Once you send the forms data, how do you read the resulting output from the server? The URLConnection class is designed so that you can use an instance for both output and input. It defaults to input-only, and if you turn on output mode without explicitly setting input mode as well, input mode is turned off. If you do both explicitly, however, you can both read and write using a URLConnection:
c.setDoOutput(true);
c.setDoInput(true); The only unfortunate thing is that, although URLConnection was designed to make such things possible, version 1.0 of the Java library doesn't support them properly. As of this writing, a bug in the library prevents you from using a single HTTP URLConnection for both input and output.
//MY COMMENTS
When you doing URL encoding
you should not encode it as one string becouse then it will encode the '=' signes and '&' signes also
you should encode all the field names and values seperatly and then join them using '&'s and '='s
Ex:-
public static void addField(StringBuffer sb,String name, String value){
   if (sb.length()>0){
      sb.append("&");
   sb.append(URLEncoder.encode(name,"UTF-8"));
   sb.append("=");
   sb.append(URLEncoder.encode(value,"UTF-8"));
}

Creating dynamic HTML form from XML data in session

I'm a bit new to servlets, please bear with me if I don't make myself clear.
currently i have a HttpServlet that extracts a XML document into a jdom Document.
this is done within the doGet() method as the XML document is in the session object.
i would like to create a popup window (a JSP or servlet) that can access the same session, convert some of the data in the XML to a submit form that users can put input into, and have the JSP(or maybe servlet) send the form data and the XML back to the original HttpServlet (through the session object).
i have a few questions on how to make this happen:
1.how to create a popup window (JSP or servlet) in a servlet, and forward the session data as well?
2.if the popup window has a submit form that submits some extra data back to the original httpservlet, will the XML document still be retained in the session?
and any advise on how to go about this problem is highly appreciated!

Hi,
This is my first time posting a reply. Hope this helps.
I am assuming that you are hitting the servlet from a link. This is one way of doing it. You can create a new window using Javascript. like this.
<script language="javascript">
var popupWin
function openWindow(page){
popupWin=window.open(page,"","width=800,height=600,resizable,scrollbars");
</script>
link
The response of your servlet will be in the new pop-up window.
2.if the popup window has a submit form that submits
some extra data back to the original httpservlet,
will the XML document still be retained in the
session?The session should be retained as long as you are hitting the same servlet container . You should be able to access the seesion variable in the original servlet if the form in the pop-up window calls the original servlet.

J2ME: Send alert (html form) from an aplication to mobile phone using SIP

Hi all,
I am new in J2ME and would like to ask for an idea on how to implement the above. I have installed both the application and WTK on my localhost.
The development would consists of three parts, the 1st two done in isolation:
1) WTK to visualize an HTML page on the mobile screen
2) The application (PHP, apache, mysql) to send out an HTML page
3) Lastly, an integration will need to be done to connect the application and the mobile device via the SIP protocol
Any ideas on how to solve the above is highly appreciated.Thanks!

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.

How to retrieve input data from a HTML form in the UTF-8 cha

I encountered the following problem with a JWeb Application:
I tried to write a JWeb-Application for OAS 4.0, that retrieves
input data from a HTML form and writes it into an Oracle
database.
All processing should be done in the UTF-8 character set.
The problem is, that the form data retrieved by getURLParameter
are always encoded in a non-unicode character set and I found no
way to change this.
Can anybody tell me what I should do to get the form data in the
UTF-8 character set?
null

Hi
Try set in the JWEB application's Java environment such
SYSTEM_PROPERTY: file.encoding=UTF8.

Open a html page from an applet

Hi,
I would like to open, from an applet, an HTML page in a new window with a specific width an eight.
Who can help me ?

Here is an example of applet to javascript with liveconnect:
http://www.narhari.com/java/applet2javascript/
You can use the send(String) method from the sample applet to send something like:
window.open('xyz.html','myPopup','width=200,height=200');in order to open a window with specific dimensions
of course you can also build HTML in your applet and use send() + some javascript to render it.

Creation of fillable forms from existing HTML documents

Hi All,
I know this is doable, but I was wondering if someone could point me in the right direction or perhaps to an existing HowTo.
I recently started working for a company in which part of my job duties includes the creation of new users and deauthinication of terminated user accounts. The company uses specific forms for accomplishing this that are filled out from templates in Outlook 2010, i.e. New Items-->More Items-->Choose Forms. This provides the users with a list of forms. By clicking on one of these forms it opens an e-mail that the requester populates.
The issue we are having with this is that sometimes they use the form, and/or don't provide the right information. They will modify the form and delete certain row or columns etc. They also have a tendency to not provide all the mandatory information.
I can take these forms and save them as HTML document from Outlook. What I would like to do is create them as fillable PDF forms with some fields as drop downs, other as mandatory and once they have completed the form correctly, (at least to the extent I can make it fool proof), then they can click on a button that will allow them to e-mail the completed form to the desired recipient admin group via outlook.
The current method is the requester fills out the form then e-mails it to say their manager, who then types approved and sends it back, the requester then sends it to the next person until all the needed "approves" are received then it gets forwarded to a group who is basically the clearinghouse for all access requests who then send it to the appropriate systems admin group emails for completion. Once complete the admins do a reply all with users created or deauthinicated etc for systems xxx and xxx as requested at the top of the e-mail.
I want to make this process more standardized to prevent users from not completing the form correctly or modifying the Outlook form to their own interpretation of how the form should be or leaving out mandatory information.
I would also like the form to automatically name itself with the employee number of the requestor with the date and time appended, i.e RM74651_10202014_0917 when they go to send it and place a copy of the completed form in a pre-specified network folder.
Any information, suggestions or HowTo would be greatly appreciated.
Thanks
Gordon

Hi Surabh,
Use HTML codes in notepad. Use the notepad to upload the file and create mail form. You should follow W3C standard. Refer note 1131645.
