Hai.., Mohan Rao...

I know how to use iterator...! Please read my post fully and then reply for that..!
I am seeking a solution to pass array of arraylist into the value attribute..!
or pass dynamic values to the value attribute in iterator..!

The following code is working, if i set the array index as 0 but i need to pass the dynamic values from the loop (0,1..n)...,

<% for(some condition)
{ %>
<s:iterator value="display.arr[0]">

<% } %>

Hello guys...!

I am having a problem with assigning dynamic values with value attribute of ITERATOR..!
My problem is..,

I had added some details into an array of arraylist in action class.[ ArrayList[] arr=new ArrayList[cnt] ...... arr[i].add(somebean)]
So in the arraylist 'arr', each cell is containing an arraylist i.e) group of objects.
And i had written a getter in the action class.[ public ArrayList[] getDetails(){ .... } ]

My question is..,
how can i access that array of arraylist in jsp with ITERATOR..?
Is there any way to pass dynamic values(0,1,..n) to the value attribute in ITERATOR..?

please refer the following code to analyse my scenario..!

(display-> dto objecj.
arr-> array of arraylists.)

i want to change the value in the place of question mark dynamically..! please help..!
alternative ways will also be appreciated..!

Hello guys..!

I having a doubt regarding accessing an array of arraylist in jsp using iterator tag.

In my action class i used the following codes..,

ArrayList[] arr= new ArrayList[10];

for(int i=0;i<10;i++)
arr[i]=new ArrayList<bean>();
while(some conditions)
arr[i].add(new bean(some values));

My question is, how can i access the values of arr[0],arr[1]...a[10] in JSP page using iterator.

<s:iterator value=???> <s:property value=beanvalues /> </s:iterator>

In the place of question mark what i need to replace to access the values of arr[0]...a[10] present in arr..? please give me a solution soon...!

Hello guys..!

I got a problem while using display:table tag in my page.
Currently i am using the default style for the paging banner in my page.

format.please refer my attachments and just give me a possible solution to my problem soon.

Hello guys..!

Can we return any other string(for example, String val="hello"; ........ return val; ) from execute method rather than success,error,input,none and login..?
If possible.., then tell me how can we map it in struts.xml , whether in normal way or any specific way to achieve that..?

Thank you..!

Thank you..! Komal Renu..!

I have fixed my problem by using the similar way that you are saying..

My approach was,

I created a bean for the form datum(as you said..!).
and then i just used ModelDriven interface in my action class to get the values from bean..!

Any way thank you very much for your help..!

@ Komal Renu

Here is my JSP code snippet..,

<div align="right">
メールアドレス(Mail Address)
<s:property value="MailAddress" />
<input type="hidden" name="MailAddress" value="<s:property value="MailAddress" />"/>

actually the snippet is from a confirmation page that is proceeding to Insert action.
So i need the mail address in my action to set it in my DTO object.
the code is,

UserDTO obj=new UserDTO(); // In, i had written the getters and setters for all the fields
obj.setMailADDRESS(?); // i need to pass the mail address in the place of question mark

UserDAO obj1=new UserDAO();
obj1.Insert(obj); // here i'm passing the object of DTO.., so that i can manipulate the mail address in DAO using the DTO object(obj.getMailAddress()).

This is my exact scenario.. Correct me if anything i did wrong..!

Thank you..!

You may use DTO objects to achieve your requirement..

@Komal Renu

Thank you very much for your reply..!

Generally we are using getters and setters in our action classes to get values from JSP pages
and pass values to JSP pages through OGNL.
But in order to minimize those complexity of writing getters and setters every time, we go for DTO..
So that i asked a doubt(getting value from JSP in action class with out getters and setters) like that..

I'm just a learner of Struts2 now. Please correct and guide me if my above thoughts are wrong and
give me the example code to set the values to DTO in action class from JSP..!

Thank you..!

Hello guys..!

I'm having a doubt in setting a value to the DTO object in my project.

we can set a value directly to DTO object like the below code..,

User user=new User();
user.setName("Jinoy P George");

But my doubt is how can we set a value to DTO object from a JSP form with out using getters and setters...!

User user=new User();

What may come in the place of question mark..? please post me a reply soon..!

Hello guys..!
I'm a newbie to struts, just learning it from the beginning..!

my question is,

" <package name="someName" extends="struts-default"> tag is a must part in Struts.xml or not...?
If yes then tell me what is the reason or necessity behind that..? "

I know my question is very silly. But please post me the reply soon...!

You can use a hidden fields in a form to accommodate the values...!
and you can use it in the next jsp page/Action class by submitting that form by using Java script..!

Currently i'm using display tag to print data in the form of table with page limit.
It is working perfectly.., But my problem is i want to display more than one property with single <display:coloumn> tag..!
