Bwuh? Just because your fridge doesn't have a built-in toaster, it's
worthless?

Struts is helpful for stuff you'd want to do on the server side.

An easy way to make stuff from the value stack available in javascript is to
do this in the jsp:

<script type="text/javascript">

var foo = <s:property value="%{foo}"/>; //int, boolean, etc.
var bar = '<s:property value="%{bar}"/>'; //string
var bat = '<s:property value="%{foo.bat}"/>'; //string retrieved by
foo.getBat()

//javascript logic goes here

</script>

Hope that helps,

-Brian

TBH, I just wrote it as a quick "off the top of my head" example. The basic
structure is sound, though -- I did that sort of thing all the time in my
struts project earlier this year. What do you think is wrong with it?

n.b. "foo.getBat()" does not belong on its own line - it's part of the
"//string retrieved..." comment.

In context of the other two examples, you're right; I should have used
something like

var foo = <s:property value="%{foo.foobar}"/>; //int, boolean, etc.

instead to be more clear. The lack of quotes was deliberate, though ... you
wouldn't want to quote a numeric value when you're setting it up that way.

Thanks :)

Oh, and to the OP ... my (somewhat sloppy) pseudocode is only one way to do
it. You could also set up Ajax calls to get data in JSON format from the
server. It's simpler to start out by writing javascript values for whatever
you need from the value stack, though.

I migrated from struts2.1.6 to 2.1.8.1 and all of a sudden my date
fields don't get saved any more. Has anyone else faced this issue?
Please, help. I am using plain text field for date and using getter and
setter methods in the model class to format the date.


the form has
<s:textfield key="t1gen.vdat1s" required="true"
value="%{t1gen.vdat1}" size="10" maxlength="10" label="Date of Birth
(yyyy/mm/dd)"/>



Setter in the model class


public void setvdat1s(String vdat1s) {
 this.vdat1s = vdat1s;
 if (vdat1s != null) {
    try {

   this.vdat1 = Format.parseDate(vdat1s);

    } catch (Exception e) {
   e.printStackTrace();
    }
 }
  }

vdat1s is a String ad vdat1 is Date.

Parminder Lehal
