Struts: button

Dear Struts users,
What is the "pure struts way" to make a button in a jsp page and generate an action when the button is hitted?
Regards,
PY

If u want to use a submit button u have declare the action in form and noting to do in the submit button..
If u are using simple buttons and need to catch the actions, go for lookupdispatch action frame work..

Crystal Report/STRUTS: Error (404) when clicking on Control Buttons (Print, Export, Next, Previous, etc...) on report viewer

Post Author: jwenny
CA Forum: Deployment
Need help badly!!!
We are using the crystal reports plugin for STRUTS.
We are able to display the report in the crystal report viewer. However, when we click any control buttons (print, export, etc...), then we get:
JSPG0036E: Failed to find resource /Report-viewer.jsp
We then moved Report-viewer.jsp to the WebContents folder (root directory) and got a different error when we clicked any control button:
Error: 400 page not found
Does anyone know how to solve this problem? For instance, is there a setting or parameter that needs to be set?
Greatly appreciate any help!

HI,
Whenever we print the viewer does an auto postback, I believe due to this some of the values are getting missed. Moreover we are referring to the viewer and reportdocument object, it seems. So can you try this simple code in an application to see if it helps:
ReportDocument rdoc = new ReportDocument();
rdoc.Load("C:\TASKECrystalReports\Intraday.rpt");
rdoc.SetDatabaseLogon("uid","pwd");
rdoc.SetParameterValues("parameter name","value");
CrystalReportViewer.ReportSource = rdoc;
Helps?
Thanks.

make sure you add a field and setter getter for your submit button

Struts : checkbox status is unchanged if i use back button and uncheck it.

hi
I have a couple of checkboxes in a jsp page used in struts framework. I am using DynaValidatorForm as form bean with session scope, so it means the properties are mapped only in the struts-config.xml. the checkboxes' property names are checkbox1 and checkbox2.
now the in the action class, i do:
public ActionForward execute(ActionMapping mapping,
            ActionForm form,
            HttpServletRequest request,
            HttpServletResponse response)
     throws Exception {
          DynaValidatorForm dynaform = (DynaValidatorForm)form;
                                          System.out.println("1st checkbox value:"+ dynaform.get("checkbox1") );
                                          System.out.println("2nd checkbox value:"+ dynaform.get("checkbox2") );
}Now if I check the first checkbox and press on submit button, the action class prints out:
1st checkbox value: on
2nd checkbox value: off
this is as expected
Now I click on the back button, then i uncheck the first checkbox and click on submit.
the output is same as before, i.e.:
1st checkbox value: on //wrong
2nd checkbox value: off
I expected it to be
1st checkbox value: off
2nd checkbox value: off
That means if in a session if i check on checkbox 'on', and i go back and uncheck it, the uncheck is never stored, i.e. the property is never set to 'off' .
Now if i check the second one, and click on submit, output is :
1st checkbox value: on //expected off
2nd checkbox value: on //correct
now i go back and uncheck the 2nd checkbox (the first checkbox is already unchecked before), click submit and i get this output:
1st checkbox value: on //expected off
2nd checkbox value: on //expected off
Please let me know what is happening. I expect the values of uncheck boxes to be 'off'
thanks

The String[] thing is only useful when you have multiple checkboxes of the same name.
What is the scope of the form bean? Request or session? If it's request, then that makes no sense. If it's session, then it does make sense because the same bean is being used, and as a result, the values are not really reset. And since HTML forms work by not submitting anything for unchecked checkboxes, then the server doesn't get anything in the request form data to know to change the checkbox to any other value.
If you are using session scope, then make sure you have a good reason to. Otherwise, use request.

Struts submit button focus

Hello
I have following prob:
a form with three buttons
a submit (normal html-button)
a cancel (struts html:cancel button)
and a reset (struts html:reset button)
since I need javascript to run before submitting
and after the result of the javascript function deciding if submiting or not I used a submit html-button (I cannot stop the struts html:submit button from submitting even if a put a javascript onClick after the javascript function comes the submition (is there a way to stop it?)).
For the other two buttons the struts html tags.
Now if the user press enter (regardless where the focus is in the form) the cancel action is being activated (the form cancelled)
if I use javascript to put the focus on submit, as soon as the user click on a text field (or any other form component) the "button group focus" moves to the cancel button!
(regardless where was the focus is in the form)
How can I get the "enter key focus" staying on submit?
I already tried the struts <html:form ... focus="submitButton"> and it works at page-load-time BUT as soon as the user click on a text field (or any other form component) the "button group focus" moves to the cancel button ! ! !
Is there a kind of "enter key" focus which works independent from the fields focus?
Thanks!

The regular way to cancel a javascript action is to return false from the onclick event.
I don't see any reason it wouldn't work with html:submit
ie
function checkSubmit(){
if ( checkIsOk){
return true;
alert("You got it wrong moron!");
return false;
<input type="submit" onclick="return checkSubmit()">

Using Struts, On submit button in child window, its opening new window.

We are developing a project using Struts and BC4J. I am opening a child window(window.showmodaldialog) from main window using struts action. Actually Child window is a search kind of page. User will enter the search criteria and press the sumbit button. I want to display the search result in the same window using datatable when jboevent="submit". But its opening new window and displaying the result in that. However in <html:form>, Even I tried the target="_self".
I am not sure wether the associated action in the <html:form> is forcing to open a new window.
Similar kind of thing I am able to achieve in other similar search page, it its not a child window.
Please let me know what I am missing.
Thanks,
Arvind

So you want the search window to submit back to itself so you see the search field and a result list..?
In pure Struts terms either using "_self" or the name of the popup window in the <html:form> tag will do the trick
You need to make sure that the inital window that you created as the popup search window has a name in the first place - can you specify this with showModalDialog()?
BTW isn't showModalDialog an IE only feature...

Back button in struts html

hi,
i am new to struts and developing an application in struts.
I have a form having 2 buttons say update and back. update button on clicking will call a bean and will update the database based on values provided in form.
I want to know how i have to provide parameters for back button???
regards,
Rapinder.

All depends on what you want to do when going back.
Depending on what you want its simple javascript, a submit that will redirect to the first page or something far beyond what this forum is intended too

Radio Button in Struts

Hi,
Is there a way that I can preselect a radio button by using taglib in Struts?
For example:
In regular html code:
<input type="radio" name="gender" value="female" checked>Female
<input type="radio" name="gender" value="male">Male
But with taglib, I can't use "checked"
<html:radio property="gender" value="female">Female</html:radio>
<html:radio property="gender" value="male">Male</html:radio>
Is there any way I can make the radio button checked?
I have also posted this message to JSP forum couple of days ago.

This may be redundant but the descriptions above weren't clear to me and I was using a DynaActionForm for my JSP. So here is the solution with a little more detail if you are using a org.apache.struts.action.DynaActionForm.
No javascript needed.
In your struts-config.xml file specify a <form-property> like so...
<form-bean name="myName" type="org.apache.struts.action.DynaActionForm">
<form-property name="action" type="java.lang.String" initial="rework" />
</form-bean>
The value of the attribute 'name' in the form-property element needs to match the name of your radio button in your jsp page. In this example 'action' is the name of my radio buttons. Here is my JSP <html:radio> tag.
<logic:iterate id="act" name="actions" type="org.apache.struts.util.LabelValueBean">
<html:radio idName="act" property="action" value="value" /><bean:write name="act" property="label"/>
</logic:iterate>
Notice that the value of the attribute 'property' in the <html:radio> element has a value of 'action' which matches the form-property 'name' attribute.
Now the only thing left is your controller Action. Here is a code snippet of what it should look like...
ArrayList alActions = new ArrayList();
alActions.add(new LabelValueBean("Rework", "rework"));
alActions.add(new LabelValueBean(Unpublish, "unpublish"));
params.getRequest().setAttribute("actions", alActions);
Now the attribute you are setting in the request object ("actions") should match the <logic:iterate> 'name' attribute.
That should be it. The Rework radio button will be select by default with this example code.
Hope that helps.

Open the default email application through button click in struts

Hi can someone help me with launching the default mail application from a jsp page through button click? I am using struts.

Yes you can send the dynamic values to the JS,
I have never tried <bean:write but you can use as,
var make="<%=makeFromJava%>"Where make is a JS variable and makeFromJava is a java variable where you can sent/set some dynamic values

Loading list of radio buttons- Struts

Hello All, i have a question based on this. How can I load a list of radio buttons instead of list of select values.
For eg., I have 5 questions and each question has 2 answers (yes/no). I iterate 5 questions coming from database. Now i need to generate 2 radio buttons (yes/no)for each question. The values for these radio buttons is also coming fom database.
I have sample code for generating list of drop downs. Can anyone help me with generating list of radio buttons. This is the sample code:
<html:select name="formBeanName" property="beanproperty" styleClass="formElementSelect" indexed="true">
<html:optionsCollection name="formBeanName" property="List" label="textValue" value="id" />
</html:select>
Thanks,
Sai

sai,
your bean C needs one more set of getter and setter to store noValues./text
<BEAN name="C">
<PROPERTY name="idYes" type="java.lang.String" access="get,set" />
<PROPERTY name="yesTextValue" type="String" access="get,set" />
<PROPERTY name="idNo" type="java.lang.String" access="get,set" />
<PROPERTY name="noTextValue" type="String" access="get,set" />
</BEAN>
When you populate that bean if it is 'Yes' then set yes fields else set 'No' fields.
then in jsp you would do..
I used nested tags which are convinient than logic tags..You can use it too.
I am not sure if this syntax is correct...for logic
<logic:iterate property="a" name="AForm" >
<bean:define id="b" property="b" type="java.util.List"/>
<bean:define id="yesValue" property="idYes" name="b"/>
<html:radio idName="b" property="idYes" value = "<%=yesValue%>" />
<bean:write idName="b" property = "yesTextValue"/>
//this will render radio as <input type="radio" name="a[0].value" value="yes">     yes
//for no
<bean:define id="noValue" property="idNo" name="b"/>
<html:radio idName="b" property="idNo" value = "<%=noValue%>" />
<bean:write idName="b" property = "noTextValue"/>
//this will render radio as <input type="radio" name="a[0].value" value="no">     No
</logic:iterate>
for nested it would be
<nested:iterate property="a" name="AForm">
//generate radio option for yes
<nested:define id="idYesValue" property="idYes" type="java.lang.String"/>
<nested:radio value='<%=idYesValue%>' property="value"/>
<nested:write property="yesTextValue"/>
//generate radio option for no
<nested:define id="idNoValue" property="idNo" type="java.lang.String"/>
<nested:radio value='<%=idNoValue%>' property="value"/>
<nested:write property="noTextValue"/>
</nested:iterate>

How to check the default checked value for radio button on jsp for struts

Hello , I just want to check the default checked value in JSP for a radio button, how can i do that?
<html:radio property="sale" value="permanent" style="vertical-align: middle;">Permanent</html:radio>
<html:radio property="sale" value="temporary" style="vertical-align: middle;">Temporary</html:radio>

you can set the default value for property ( which you want to default selected when the form is first loaded) in reset method of the form.
<html:radio property="sale" value="permanent" style="vertical-align: middle;">Permanent</html:radio>
<html:radio property="sale" value="temporary" style="vertical-align: middle;">Temporary</html:radio>
In the above case you can write the code as follows in the perticular form of this jsp.
public void reset(ActionMapping mapping, HttpServletRequest request) {
super.reset(mapping, request);
sale = "permanent";
This will show the first check box default selected when the first time the page is loaded.
