Html:checkbox

I have a checkbox in my JSP which is checkd a the beginning.
My getters and setters inside the ActionForm is lik
private String chkFlag;
public void reset(ActionMapping mapping, HttpServletRequest request) {
          ChkFlg = false;
public boolean isChkFlg() {
          return ChkFlg;
     public void setChkFlg(boolean ChkFlg) {
                            this.ChkFlg = ChkFlg
     }In my logic i have
//actionForm is the name of the ActionForm
if(actionForm.isChkFlg() == true){
//do sth here
}else{
//do sth here
}However, no matter whether the checkbox is selected or not it always gives me false
What am i doing wrong? how can i use checkbox?

Please post Struts questions on a Struts forum or in the JSP forum [ http://forum.java.sun.com/forum.jspa?forumID=45 ]

Is There a Bug in pdk-html:checkbox .... ?

I am attempting to use the <pdk-html:checkbox ....> tag and cannot get it to work.
When the user presses the Submit button and my code processes the checkbox the checkbox does not reflect that the user checked it.
The code I wrote in the .jsp is:
<pdk-html:checkbox value="yes" name="facListBean" property="check_box"></pdk-html:checkbox>
When the page gets rendered the code gets translated to :
<input type="checkbox" name="check_box" value="yes">
Notice the name is not qualified in any way. In the other pdk-html tags I have used the name gets prepended with qualifying data.
Is this a bug in the pdk-html:checkbox tag? Has anyone else use the pdk-html:checkbox successfully?

Thanks Don,
I was unaware of the multibox tag so I looked into it after reading your response. I tried to implement the following example code I found on the Husted web site:
JSP:
<logic:iterate id="item" property="items">
<html:multibox value="val" property="selectedItems">
<bean:write name="item"/>
</html:multibox>
<bean:write name="item"/>
</logic:iterate>
Action Form
private String[] selectedItems = {};
private String[] items = {"UPS","FedEx","Airborne"};
public String[] getSelectedItems() {
return this.selectedItems;
public void setSelectedItems(String[] selectedItems) {
this.selectedItems = selectedItems;
I get the error:
"You must specify the value attribute or nested tag content"
I added a value attribute to the multibox tag but that didn't change the error. Any idea what what I need to do here? What am I missing?
Thanks,

Doubt in using html:checkbox in struts

Hi all,
In my jsp page i have 2 checkboxes name mandatory and active.
<html:checkbox property="mandatory" value="true"/>
<html:checkbox property="active" value="true"/>
Insertion of data works fine,and now my doubt is about the edit mode.
In edit mode,depending on th value of thethese fields wheteher 0 or 1,checkbox should be checked.how can it be done?
In th corresponding for,the properties I declared as boolean values.Also reset method is provided .
Anyone pls help.
thanks

It's rather nasty, but you could wrap all your strings in <html></html>. Even so you still have to use entities, but the
following displays what you want:JLabel lbl = new JLabel("<html><html></html></html>");

Html:checkbox - which box is selected and on in what tr

I have a jsp in which I iterate over a LinkedList of people. Each person gets there own row in a table on the jsp page. In each row is the name of a person in the first <td> and then a checkbox in each of the next three <td>'s.
A user may order one of three reports on any or each of the names coming from my LinkedList by clicking on a checkbox.
Right now I am able to determine which report to order by which checkbox is selected in a row, but am unable to determine which row/person to order the report for.
I've seached this forum and went through the first couple pages of results with no luck. And spent a bit of time on google but can't seem to get the exact keywords to retrieve the results I need.
Here is a small sample of how I am setting up the table. Just a snippet, names have been changed, you won't be able to compile this.
<logic:iterate id="person" name="someLogical" property="personsList" type="someDataObjectType">
     <tr>
          <td valign="top" nowrap>
               <bean:write name="person" property="name"/> �
          </td>
          <td align="center" valign="top">
               //someForm is my actionForm, and orderReportOne is a boolean being set in the form
               <html:checkbox name="someForm" property="orderReportOne"/>
          </td>
          <td align="center" valign="top">
               <html:checkbox name="someForm" property="orderReportTwo"/>
          </td>
          <td align="center" valign="top">
               <html:checkbox name="someForm" property="orderReportThree"/>
          </td>
     </tr>
</logic:iterate>The booleans in my form are being set correctly but don't relate to a specific person. They would just order reportOne for each person in the list.
Edit: I will be leaving soon for the rest of the day and may or may not be able to reply again until monday, but appreciate any responses. Thanks

It depends on how you're utilising your XML, but ComboBox has selectedIndex property so that you can trace the index number of the item selected.

Read/set HTML checkbox in JSP

Hello,
I need to directly read and set the state of an HTML checkbox from a JSP page that contains it. It is not sufficient to submit the form and then get the value from the next page; I need to be able to set the value when the page loads, and then on cue, store the (possibly changed) state of the checkbox within the same page.
How can this be done? Thanks in advance.

you write the checkbox tag dynamically...
<input type="checkbox" ... <%= checked ? "checked" : "" %>>
or use a tag library that does it for you.
But you can't do it within the page without Javascript. Once it loads in the browser, the Java part of the page is done and gone. So either you use Javascript to alter things in the browser before submitting the form, or you submit the page and recreate it based on what's submitted so far.

html:checkbox disabling based on a condition

does anyone know how to disable the <html:checkbox ?? it should be disabled based on some condition
thanks

It is very unclear what you want. There is a disabled flag available to html:checkbox. You could do something like:
<html:checkbox disabled="<%= somebooleanVar %>" ...and so on. What are you trying to do?

html:checkbox driving me crazy

Hey frnds
Can u plz provide me some code for managing a group of checkboxes in struts.
I m using DynActionForms

i m having a dyna form like this........\
<form-bean name="addQuestionForm"
type="org.apache.struts.validator.DynaValidatorForm">

Problem using pdk-html:multibox and pdk-html:checkbox

Hi all,
I am developing a PDK struts application using OC4J 10.1.2. I have to create some form pages which are going to have some checkboxes. I have tried to follow the following code in order to use the pdk version of the checkbox in my form:
in jsp file
<logic:iterate id="item" property="items">
<pdk-html:multibox property="selectedItems">
<bean:write name="item"/>
</pdk-html:multibox>
<bean:write name="item"/>
</logic:iterate>
Given an ActionForm setup like this
private String[] selectedItems = {};
private String[] items = {"UPS","FedEx","Airborne"};
public String[] getSelectedItems() {
return this.selectedItems;
public void setSelectedItems(String[] selectedItems) {
this.selectedItems = selectedItems;
....... //getters and setters of items//
In the reset method I also reinitialize the selectedItems array like :
selectedItems=new String[]{};
But the value of the multibox is not reflected in the action class. To my surprise, the html code generated by the server is similar to ordinary checkbox which ideally should carry some portlet specific information like pdk-html:text
Same is the case with single checkbox. I have created a boolean variable for the single checkbox in the actionForm class. But same problem frustrates me again. The value is not passed simply.
Can anybody comment. Is this some kind of a bug or may be there is no support for checkbox and multibox in pdkstruts.jar (10.1.2.0.2).
Best regards,
Omer

Html:checkbox tag problem

I need to use multiple checkbox(i.e One checkbox in each rows).I am using Struts1 and need to capture the list of values which the users selects the checkboxes.Need information to capture the selected values in action class.sample code could be more helpful..

In Struts i think there are some variables in formbean which will store the value of forms parameters so you can access these values by form object passed in action class.

How to get the checked attribute of a checkbox item from a PL/SQL process?

Hello,
I have a simple static form with one checkbox linked to a LOV containing one single value. I use this checkbox just to enable/disable other fields via Javascript. I am interested to fetch the "checked" attribute of this checkbox (and not the value of the checkbox) from an After Submit PL/Sql page process, so that I can process only the enabled fields.
I can already imagine a workaround where we may store via Javascript the checked attribute of this checkbox in an hidden page item and then getting it from there, but I would really like to avoid it, as it would add unnecessary complexity and I would have to add more code to keep the hidden item always in synch with the checkbox status.
Is there something like the V('page_item') PL/Sql function that can get a different attribute from a page item (like the checked one from a checkbox) and not only its value?
I searched the forum for an answer to my question, but I couldn't find anything related.
Thanks a lot,
Paolo

Paolo,
HTML checkboxes are POSTed only if they are checked. So if your "checked" value is 'Y', for example, then your after-submit process can check if the item's value is 'Y' or not. Of course, you must be careful to set that item to null (or some non-checked value) in session state during page rendering so that previous values are not retained.

Checkbox derived column in report

I added an HTML checkbox that has the same name for every row and a value of the pk for that row to a report. I also added a submit button.
The submit button branches back to the same page.
If I don't check ANY checkbox buttons the submit button just takes me back to the same report. If I even click one checkbox, I get a 404 "Page cannot be found" with the url saying: pls/htmldb/wwv_flow.accept
why is this procedure doing this? How can I add a derived column containing a checkbox to a report for selection of report rows for further processing or adding of these rows to a "shopping cart/basket".

Enough with this ..... link
http://www.oracle.com/technology/products/database/htmldb/howtos/checkbox.html
How many times do we have to see it in the forum....Enough.....
Its so frustrating giving the same link time and time again...And the funny
part is that most people's questions has nothing to do with that. But
still some geniuses give the same link....I just feel so sorry for people
who are struggling to get a answer and some idiots give the same link

Use of titleKey attribute in html:select tag

Hi,
There is one "titleKey" attribute to create mouse over pop-up texts taking key values from property files in case of i18n. It works for every struts specific tag like <html:text titleKey="help.rmc.name"/> or <html:checkbox titleKey="help.rmc.name"/> except for <html:select> tag which is used for creating combo box or list box. But this tag contains the titleKey attribute.
Please give me some suggestions how to implement this mouse over pop-up texts in case of <html:select> tag
