Hi,

I am building a online examination system using struts 1. Now to fetch the next question I am making a ajax call to action class and action class should return an object i.e. QuestionDTO. The problem I am facing is I am not able to read/parse that object in java script.

Can anybody tell me what is the best approach to achieve this? Means do I need to use Json like thing? or return a String and split it in java script?

Thanks in advance..!!!

Hi,

In my application I have a date 05-09-2012 and I want to print this in text format.

e.g. 05-09-2012 should be printed as Fifth of September Two Thousand and Twelve

or something like that...

Is there any way I can do this quickly?

Thanks in advance..!!!

Hi,
In my application I am currently using my own javascript for selecting date. But it is giving some problems like browser compatibility. So now I am thinking of using dojo for date selection. But I am not clear about how will the dojo's text box will get associated with my form bean's property. Any help is welcome.. :-)

second time iterate through books and books is in category. So in 2nd iterate statement put name as category or cat, as you have given id for category property... This should work..(I hope)

Do one thing in your form bean store categories plus a set of books of that category, that way you will have your bean something like:
String category;
Set<Book> books=new HashSet<Book>();//Book will be another class with book info. now you can store book objects in books set.

in your jsp get category and then iterate through books set using <logic tags>

do a little googling on set's. You will get lots of tutorials on sets. If problem still persists tell me.

So, line number 1 populates the category object.
In line number 2 categoryId(say categoryId of 'Networking') will determine which books (i.e 1) Network Fundamentals 2) Networking Concepts 3) Network Guide) to fetch from the database and populate the books object.




you cannot trigger action automatically at line 2. What I will suggest is fetch all the data first(both categories and books) and put them in collection (like Map). Now in jsp display the map...

exactly, because at a time you are going to display only one username. getAttribute method will return the value of current session only..

Now when I am logging in with the same user credentials by a User Login servlet
I am again saving the username in a session and want to display username in UserHomePage.jsp

So do I have to put session.getAttribute() again in the UserHomePage.jsp ???



Shivang do you want to display username two times? if not a single session.getAttribute should work

Thanks for your reply.

categoryNo is not the hyperlink.
When the jsp is loaded the category object is also loaded.
Somewhat like this:

And my problem is I am not able to fire an Action in line number 2.


still not able to figure out your problem... what are you displaying on this jsp is list of categories or directly list of books ? abd if books then of which category? and if category then why do you need to fire action class at line 2? you can give a submit button and then trigger action.

I use this class to access "connection", there are times where connection might be closed, and performing any operation gives me "connection already closed" error.

is there anything like,


So that I can check it in advance before performing the operation?
Any suggestions are welcome. Thanks!
