Re: c:if and boolean value
Thanks for the suggestion, Tim. I actually did buy Shawn's book (in PDF
form), I just haven't quite gotten familiar with it to remember all the
resources that are there. Still used to hard-copy, I guess :-) .

John,
Download the PDF at this URL and keep it around:

I've found it quite useful in terms of referencing JSTL tags, and for finding examples
of how such tags are written. I certainly wish it had a bit more examples, but I suppose thats why you buy the book, as Bayern would like. :)

That works great, thanks to both Tim and Pierre. One follow up question
though - is there a c:else tag to go with the c:if?
Thanks again!

Yeah, that occured to me after I sent off the email and was sitting on

Anyway, more ways to skin the proverbial cat...

Try the following:
c:if test=${mapservice.running}
[What Timothy suggested would also work, but there is no need
to test against true, since you already have a boolean expression
for your test.]

offhand, id say you should be doing this. (enclose the entire

Hello All,
I have a isRunning() method in my bean that returns a boolean. I'm
try to test against that value with something like the following:

/c:if
The problem is that even though the bean's getter method is properly
returning the true value (I can print it into the HTML page), the
above conditional always fails. Can someone point out what I'm doing
wrong?
JSTL v.1.2, core library.
Thanks!

Counter using Struts Taglibs
Hi All,
How can I define counters using Struts EL tag libraries for printing purposes in
JSP pages
Here is an example
table border=1
c:forEach var=transid items=${trans.transactions}
tr
tdc:out value=${transid.acctno}//td
tdc:out value=${transid.testcode}//td
if($transid.testcode==ts ) tscount=tscount+1;
tdc:out value=${transid.srcfac}//td
tdc:out value=${transid.dateofservice}//td
tdc:out value=${transid.htkey}//td
/tr
/c:forEach
/table
In the above code i would like to print the total and number of iterations the for
loop performed.
I would also like to do some condition to inside the for loop to print another
specific counter
like
eg:--
if($transid.testcode==ts ) tscount=tscount+1;
I am novice and have recently started using these tag libraries.Is there a link or
web site which has tutorials on how to use the tag libraries.
Any help appreciated
thanks

Using Standard Tag Library to Display a Request Attribute
I'm struggling with displaying a request attribute with the
Standard tag library. I would like to display the
javax.servlet.error.message request attribute, but nothing
is displaying. The following format doesn't display anything:
c:out value=${requestScope.javax.servlet.error.message} /
However, I can see an error message if I use this:
c:out value=${pageContext.exception.message}/
Is there a trick to displaying request attributes with
JSTL? Is the expression language interpreting the periods
in the attribute name?
Regards,
Garrel Renick

It looks like you're really asking about JSTL tags, not Struts.
You can use c:set to increment a variable, as in
c:set var=counter scope=session value=${counter + 1} /
I am novice and have recently started using these tag libraries.Is
there a link or web site which has tutorials on how to use the tag
libraries.
The JSTL specification is available at http://java.sun.com/products/jstl.
If that's too technical for you at the moment, there are also several
books on JSTL; more info on mine is available at the URL below.

Yes, it is. To avoid this, you can use expressions like the following:
c:out value=${requestScope['javax.servlet.error.message']} /
The [] syntax works wherever . works, but it lets you avoid problems when
the property name itself contains a period.

looping/ iterating over a collection ina a collection
for some reason i am unable to loop over a collection in a coolection for
example:
i have a class with a field called basket
which is a collection of Items which contains a field called contents.
for some reason i am unable to access the the contents in Item
with the follwing code:
c:out value=${sessionScope.Cart.basket[0].content[0].name} /
or
c:forEach items=${sessionScope.Cart.basket} var=i
c:forEach items=${sessionScope.Cart.basket[i].contents} var=x
c:out value=${x.name}/
/c:forEach
/c:forEach
i hope this make sense but the bottomline is iam trying to access a
collection in a collection and i cant seem to be able to do it
