Re: iterating over a collection

Use 'name="allTheCoins"' instead of 'collection="allTheCoins"'.

RE: iterating over a collection

[Anish Acharya]

Thanks for the response.  Unfortunetly specifying the class as
"java.lang.String" (since that is what my vector contains) has
no effect.  Any other ideas?

Thanks,

Anish,

Try specifying the type property of the logic tag.

>From the Jakarta Struts site...

"Fully qualified Java class name of the element to be exposed through the
JSP bean named from the id attribute. If not present, no type conversions
will be performed. NOTE: The actual elements of the collection must be
assignment-compatible with this class, or a request time ClassCastException
will occur."

So your logic tag would look like:

Hello everyone.  Just wondering if anyone can spot the error in this code:

<% Vector allTheCoins = (Vector)(application.getAttribute("allCoins"));
%>




 





I have traced it to the logic tag -- the vector does initialize properly.
All of the elements
of the vector are strings.  Struts gives me an error claming it "can not
convert Java.lang.String
into Java.lang.object".

I've pulled out all my hair trying to figure this one out -- any help would
be appreciated.

Thanks in advance,

-Anish

The docs say it has to be a run-time expression.   Without the <%= ... %>
then its just a plain ol' String.
