Subject Re: [S2] Ajax error
Date Wed, 10 Sep 2008 12:08:29 GMT
Thanks Dave.

Yes, from action class I m returning entire jsp page.

Action class:

    public class TimeServer extends ActionSupport {
        private Date date = null;
        public String execute() throws InterruptedException  {
            System.out.println("Request received...");
            date = new Date();
            return SUCCESS;

        public Date getDate() {
            return date;

    <package name="ajaxdemo" extends="struts-default">
    <action name="TimePage" >
        <action name="Time" 

initially I m requesting TimePage.action.

an HTML fragment, which is what you'd probably want.
How can I return HTML fragment? you mean another jsp page which contains 
only that html fragment? If it is the case I may have to create many 
small jsps, which may in the order of 100s. Or you talking about some 
thing else?

And is there any way to substitute the <s:submit...> with <s:a..>. I've 
tried with this, but only submit is making request to action.

Thanks for resource links.
