How to submit a form with checkboxes in a page flow?

I'm having some trouble with a form that contains several checkboxes, and
how to submit this form within a page flow...
I have a JSP page containing a form with N checkboxes. The value and
checked/unchecked status of each checkbox is generated from parsing an XML
document. Here is the (simplified) code:
<%@ taglib uri="http://java.sun.com/jstl/xml" prefix="x" %>
<netui:form action="doUpdate">
<x:forEach select="...">
<input type="checkbox" name="id"
<x:if ...>checked</x:if> value="<x:out ... />">
</x:forEach>
<netui:anchor formSubmit="true" action="doUpdate">Submit</netui:anchor>
<netui:anchor action="doCancel">Cancel</netui:anchor>
</netui:form>
When this form is submitted, the checkbox values are lost -- the following
code (in the action) produces an empty array:
String[] prefs = this.getRequest().getParameterValues("id");
I looked at the <netui:checkbox> tag, but it does not appear to give me a
way to set the state and value (unless I've missed something).
Can I submit a form without using a form bean? If I do use a form bean, can
I set the state and value from my JSP?
Any suggestions on how to do this (or insights into what I'm doing wrong)
are welcome...

I am new to this, but I think this may solve your problem:
I am not sure if this is what you are looking for, but you can create a LinkedHashMap
with the req key/value pairs in the page-calling action in the pageflow and then
pass that via a getRequest().setAttribute("myCheckboxes",myCheckboxHashMap);
You can then access it in code using the optionsDataSource portion of the netui:checkBoxGroup
- ie
<netui:checkBoxGroup dataSource="{actionForm.thisCheckbox}" optionsDataSource="{request.myCheckboxes}">
Hope this helps!

How to submit two forms once in one jsp page?

hello all,
My jsp page includes two forms: one form's action is a File Upload servlet, which process file uploading; another is a general servlet to collect user inputs, such as user name, age, etc.
Because the file upload servlet is a legacy component, and it was used in many applications. we could not meger it into our business components.
the system requires the file upload and information collection are submitted once. so we have to submit two forms in one 'Submit' action, at the same time, the information collection servlet need get the information from file upload servlet, such as the uploaded file's url.
I have tried two methods, but all failed
1. Upload form has no a 'Submit' button, when user click the 'submit' button of the information collection form, we use a javascript to submit upload form first, then submit information collection form. Failed at: the second submit dose wait for upload finishing, then the second submit interrupt the upload
2. the javascript only submit upload form, and set HTML body's onUnload event to another javascript that submit information collection form. this time, the file upload sucess, and information collection form sucess at most time. But fail when user click the 'refresh' or 'back' or any navigator buttons of the browser. these action will trigger the page 'unload' event too, but the submit if invalid!
Please tell me how to.

chain the both requests!
- build one mutlitpart request and send it to a servlet that can handle that multipart request (think of using oreilly MultiPartParser).
- check the input (all requiered fields and files there)
- if yes store the user fields and create a socket connection from your servlet to the legacy file upload servlet and post the file this way.
- like this you have full control over the users input and can make sure the file and the fields are just save if all requiered elements are availble.

How to create a form with jsp

I want to create an HTML form using jsp.
It has a couple of selection boxes. The options for the selection box needs to be read from a file.
As I understand it can create the form in HTML. And somhow uses jsp to read a file on the server get, the data and create selection box. I can have a class on the server side that does the actual read - forexample
SelData.class.
Would appreciate it if some one can outline how this is done.
- thanks

* Pass the data used to populate the select options to the JSP page in the form of a bean.
* In the JSP page, iterate through the bean, using the data to "fill in" the attributes and body of the option tag.
This tutorial should help a great deal with these concepts: http://java.sun.com/webservices/docs/1.1/tutorial/doc/JSPIntro.html#wp69778

How many ways you can invoke JSP from OBPM

Hi All,
I just wanted to know how many ways we can invoke JSP Page from BPM.
1. BPM Interactive component call
2. ?.
Thanks
Sunil.

When you are using a jsp, its for user interaction only. and in any case, you require interactive component call.
this is the only way you can use a jsp in OBPM.
However, in a bpm interactive activity - you can also choose external as implementation type.
For this, you need to have your jsp source code reference added as an external resource in the project and the external resource is to be specified at configuration while setting implementation type.

Pls tell me how to submit a form?

I want to use java class to submit a form to the web server,
but I can't find which class will be useful for it,
I find URLConnection can do it but can't set the request mothed
to "post",HttpURLConnection can do it but it is an abstract class
and I can't find the subclass,How can I do?

But the "openLConnection()" method return URLConnection instance.
Something like: new URL( "http://foo"
).openConnection() should return an instance of
HttpURLConnection.

Sending value to JSP page from Tag Handler

Is there some reason why a call to setAttribute inside a Body tag handler would not succeed in making visible a variable outside the scope of the tag? I mean a situation like this:
<% String p=request.getParameter("p"); %>
<taglib:tag count="<%= p %>">
...body which handler fills in...
</taglib:tag>
<form action="thispage.jsp?p=<% newcount %>">
<input type=submit>
</form>
Assume that "count" and "newcount" are defined in the Tag Extra Info class for this handler and that TLD allows a run time evaluation of the "count" attribute.
(The idea here is to have the handler recall the same jsp file with an incremented counter.)
Some other way to do this?
Thanks,
Alan

Never mind... I see that I forgot to set the scope of the scripting variable to AT_END in the "Handler Extra Info" class.

How to call a form on 9i from a jsp?

Hi
I have a form running on forms 9i server.
I want to call this form from a jsp page . I have developer suite 9i installed on my system. LEt me know how this can be done .
thanks
sirisha

Hi ,
I think yes...but under some circumstances....
In your formsweb.cfg file you should define a named configuration alias... such as:
[TEST]
workingDirectory=C:\TEST_DIR
form=C:\TEST_DIR\MY_NEWFORM.FMX
Then , after stopping , starting your OC4J instance..... you call that as (in a button , for example):
web.show_document('http:<your_server>:<port>/forms/frmservlet?config=[TEST]',_blank);
I have not tested it.....

Simon

How is submit a form using ahref in a JSP

I have a form inside a iframe. It has 2 buttons. On clicking one button resultant page should open in the parent window(i.e target = parent). On clicking another button resultant page should open in same window (i.e target = self).
In bith case i need to submit the details in that form. I need to do this when java script is disabled. When java script is enabled changing of target window is possible.

I have written a few applications that required this kind of function, and what I ended up with was an applet.
First, I submit to the usual ACTION-URL and after processing the data, my code would determine whether the response should capture the full screen, or appear just withing the frame.
For redirects that capture the full browser window, I would call a page (still within the frame) that would run a Java applet whose only funtion is to send the browser to the new URL, which would be sent to the applet as a param. The applet just needs to know how to send the user to the new URL.
package com.redeye.core.utils;
import java.applet.Applet;
import java.net.MalformedURLException;
import java.net.URL;
* Redirect the user agent to a new URL.
* Usage:
* <xmp>
* <applet
*   code="package.to.Deflector"
*   codebase="path/to/applet/codebase"
*   name="Deflector"
*   height="1" width="1"
*   mayscript>
*     <param
*       name="targeturl"
*       value="http://target.url.here/">
*     <param
*       name="targetframe"
*       value="_self|_top|ANYTHING_ELSE">
* </applet>
* </xmp>
* Parameters:
* <b>targeturl:</b> The target to which the user agent is redirected
* <b>targetframe:</b> name of the frame/window to be redirected
* @author http://redeye.no
public class Deflector extends Applet
     private static final long serialVersionUID = -878236489812416561L;
      * Constructs a new Deflector applet
     public Deflector()
          // Default contructor

How to submit a form in a web

Hi, it's my first post in this forum and it's for asking a very rough problem.
I want to log in a web which uses a form to authenticate. The page is: https://cv2008.uab.cat. I want that my program in java logs in and retrieves information from it (e.g. downloading a file). I've been studying the form and it uses POST method and requires to fill the username and password fields. Moreover I've found something interesting in the form:
<input type="hidden" name="lt" value="_c23CA00BA-41D7-8934-6F3E-D754BD70ECBE_kAAFD1C38-B06B-2F6E-776D-92949E17286F" />
                              <input type="hidden" name="_eventId" value="submit" />
but I don't know what to do with it.
Well, about the app, I've been trying to use common httpclient and the.net libs but I couldn't log in.
Here is my last try:
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;
public class HttpClientTutorial {
    public static void main(String[] args){
         HttpClient client = new HttpClient();
         String response = null;
         PostMethod authPost = new PostMethod("https://sac.uab.cat/login?service=https://cv2008.uab.cat/home/");
         NameValuePair[] data = {
                   new NameValuePair("username", "MY_USER"),
                   new NameValuePair("password", "MY_PASS"),
                   new NameValuePair("lt", "_c23CA00BA-41D7-8934-6F3E-D754BD70ECBE_kAAFD1C38-B06B-2F6E-776D-92949E17286F"),
                   new NameValuePair("_eventId", "submit"),
                   new NameValuePair("submit","submit")
         authPost.setRequestBody(data);
         try {
              client.executeMethod(authPost);
              response = authPost.getResponseBodyAsString();
              System.out.println(authPost.getStatusCode());
         catch(Exception e)
              System.out.println("Error");
         authPost.releaseConnection();
         System.out.println(response);
}I'd appreciate any help, thank you!

Hey malcolmmc,
you were right, that eventId field changes every time I make a client.executemethod(authPost); the problem is that I need to do it to retrieve the value of that field but after I make the authPost.setRequestBody(data); with the information to fill the form, I need to execute the method again and then the value has changed again. So, I need to retrieve the value and "without closing that session" send the form. But I don't know how to do it, I think I'm very close to achieve it 'though!
My code rightnow is:
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.NameValuePair;
import org.apache.commons.httpclient.methods.PostMethod;
public class HttpClientTutorial {
     public static String search_lt(String content) {
         String ltValue = "";
         String lt = "lt\" value=\"";
         int i = 0;
         boolean foundIt = false;
         int max = content.length() - lt.length();
         test:
             for(i = 0; i <= max; i++) {
                 int n = lt.length();
                 int j = i;
                 int k = 0;
                 while (n-- != 0) {
                     if (content.charAt(j++)
                             != lt.charAt(k++)) {
                         continue test;
                 foundIt = true;
                      break test;
          if (foundIt == true)
               i = i + lt.length();
               while (content.charAt(i) != '\"') {
                    ltValue = ltValue + content.charAt(i);
                    i++;
          else
               System.out.println("Not Found.");
          return ltValue;
    public static void main(String[] args){
         String response, ltValue;
         HttpClient client = new HttpClient();
         PostMethod authPost = new PostMethod("https://sac.uab.cat/login?service=https://cv2008.uab.cat/sessioCAS/usuari.jsp");
        try {
             response = authPost.getResponseBodyAsString();
             ltValue = search_lt(response);
              NameValuePair[] data = {
                        new NameValuePair("username", "MY_USER"),
                        new NameValuePair("password", "MY_PASS"),
                        new NameValuePair("lt", ltValue),
                        new NameValuePair("_eventId", "submit"),
                        new NameValuePair("submit","INICIAR SESSIÓ")
              authPost.setRequestBody(data);
              client.executeMethod(authPost);
              response = authPost.getResponseBodyAsString();
              ltValue = search_lt(response);
              System.out.println(authPost.getStatusCode());
              authPost.releaseConnection();
             System.out.println(response);
        catch(Exception e) {
             System.out.println("Error");
}{code}
Thank you for the help!
