Setting a JavaScript Variable to Session

Hi All,

I have an issue with setting a JavaScript variable to session. This is a string and I need to retrieve this in my Action Class and process further. I am using Struts 1.1.
I have tried setting this variable as a hidden variable however, it doesn't reach the Action Class - I get a null value.

Any suggestions on what I would need to do?

Here's the gist of what I am trying to do:

JSP:
<html>
<body>
<input type="hidden" name="userInfo" />
<input type="submit" onclick="submit();" value="Submit">
<input type="submit" onclick="cancel();" value="Cancel">

<form>
....
....
....
//make a call to foo()
</form>
<script>
function foo() {
var bar = "Divya";
document.getElementsByTagName("userInfo").value = bar;
}
</script>
</body>
</html>

Displaying a datagrid on a JSP

Hi,
I have a small form, which when filled would hit a DB, fetch some data and this data needs to be populated onto a JSP page.
My questions are:
1. Since we are talking about a datagrid being displayed, can we fetch a resultset and set it to session/ request scope - I think this is a bad design choice. But how else would I display the data?
2. If I do not use the above approach, how else can I do it? Can I store the data in a collection that can be set to request scope and display from there?
Thanks,
Divya

Replacing one DIV with another

Hi All,
I am fairly new to Java script.
My problem is as follows:
I need to replace one DIV with another.
The first div, "div1", is shown on page entry; "div2" is initially hidden.
"div1" contains a small form. On click of the submit in "div1", the back-end is hit and we fetch some data which then needs to be populated in "div2" when we get redirected back to this page, so I want "div1" to be replaced by "div2".
Any help will be appreciated!
Thanks,
Divya

Trying to run my first program: java.lang.NoClassDefFoundError

Agree with marc, when you compile you need to do:
javac <yourfilename>.java
and while running it you just need to do:
java <yourfilename>

Job seeking Problem

Hang in there Aashu, keep updating your resume every so often on the job portals - most companies look for recently updated resumes, even if it means that you have only added a space or a line. Also, it would help if you kept yourself in tune by studying and being prepared for any interviews, even if it is at a short notice, making sure that you are ready for any job opening that comes your way.

Query on arraylist

Rob, I think this looks neat and is a lot less complex than what John suggested and what I feared

Thanks for your inputs Rob and John!
