So what does that exception tell you?

(I have very limited internet access today, so I can't look up the
requirements for displaytag. but do you have all the required libraries for
it?)

The exception is telling you precisely what class is missing; this is a clue
as to what may be wrong.

Do you have *all* the libraries you need for using displaytag?

You can't just randomly add libraries to your application and expect it to
work: libraries have their own sets of dependencies. You almost certainly
don't have all the dependencies that displaytag requires.

Look up the dependencies for displaytag and make sure you have them all.
Here's the link:

http://displaytag.sourceforge.net/11/displaytag/dependencies.html

This is Java 101. I'd consider taking some time to learn the environment
within which you're attempting to program; it will almost certainly save time
and aggravation.

Dave

arum,

Read this *entire* page paying particular attention to point 2
"dependencies":

http://displaytag.sourceforge.net/11/install.html

A ClassNotFoundException always implies you're missing a jar in the
classpath.

Seems you missed to add the Apache Commons Lang library jar file.

I have projects running with displaytag 1.1.1 and commons-lang 2.3.
(Don't know if the last 2.4 version work though.)

I don't think that's caused by the validation.
That error occurs when the DatePicker attempts to set its current value
but the value is an invalid format. In this case it's blank.

My guess is that the params have been set on your action, validation is
invoked on the action, validation failed because the Date (or another
field) wasn't set, the input result was returned, the page was
redisplayed but the DatePicker failed to render itself because the date
value was null.

Use an s:property or s:date to see what the date value is after a
validation failure.

Hope that helps.

Hi Aaron,

I'm running into a similar problem - I'm using a ServletActionRedirectResult
instead of the JSONResult. Were you able to work around this? It seems
that it's been fixed in 2.1 (cf issue WW-2170) but it doesn't look like it
will reach GA anytime soon.

Cheers,
GB

Never mind. I wouldn't mind seeing other examples, but I was able to

It's a port from a combination of S1.3, actions, and servlets, so it's been
a big jump.

There aren't that many hurdles once you're familiar with the S2 way of doing
things. S2 has made life a lot easier, the UI codebase a lot smaller, and is
generally a good move.

Agreed!

O/T
I'm writing a small text-processor search utility and came across this
interesting TestCase
using StringTokenizer I want to see if I can use a delimiter only when that
delimiter is embedded in the discovered string
referencing the StringTokenizer JavaDoc from MIT
http://tns-www.lcs.mit.edu/manuals/java-api-old/java.util.StringTokenizer.ht
ml

so if I find all McCLANAHAN.. this TestCase works as McCLANAHAN characters
are alphabetic and non-whitespace

The whitespace characters do'nt work though and trip up StringTokenizer as
in this example

delimiter="'"; //as in single tickmark

find all occurences of O'Halloran

I wonder if there is a workaround so Irish names will not trip up whitespace
delimiters???

I've been working on a system for a law firm that allows them to quickly
generate legal documents. Users complete a Q&A process and a PDF pops
out at the end. The logic is more sophisticated than it sounds though.
It's now evolved into a records management system and document
management system as once generated as document have a particular
life-cycle or legal purpose. The system plugs into the Alfresco ECMS
which is an impressive little open source project.

We originally started with Struts 2.0.1. Some of the challenges have
been managing the massive increase in scope and the view and workflow
tailoring requested by every new corporate client. At my last count
this application had over 100 actions in struts.xml.
Lessons learned: I've been scared-for-life and won't ever use FOP again
(http://xmlgraphics.apache.org/fop/).

My pet project involves data mining and analysis. I've been using
Struts2.1 as a SOA framework where the actions output a response as
json, xml, an html fragment or html page depending on how it was
requested. Struts does an excellent job at that. The RIA is build upon
YUI. The biggest challenge with this project is dealing with large
datasets. Every operation hits a bottleneck, from javascript being too
slow to the servers having insufficient [insert any resource]. It's a
constant juggle between optimzing algorithms and reoganizing resources.

I have new appreciation for what Sergey Brin & Larry Page achieved in
the years before they had money or resources.
Lessons learned: Don't bite off more than you can chew

I've been quiet on this one, but since I finally had a breakthrough
today, I feel like talking about it :)

I started a pet project that I've been toying around in my head for a
while. As a parent, I coach a few elementary and junior high sports. It
is a volunteer thing, and if offered pay, I would refuse it (the schools
need the money more than I do). The biggest complaint that parents have
though is that they feel like we don't provide enough information, etc.
Sometimes I want to tell the parents that complain to shove it :), but
as a parent myself, I feel the same way about teachers, so I try to do a
better job each season. Since I setup a wordpress/phpBB site a while
back (which I haven't been too diligent about updating), I thought about
doing something similar. Having dealt once with wordpress/phpBB, I have
vowed to never do it again.

In an attempt to "eat-my-own-dog-food," I decided to do this all from
scratch with s2 and friends. So, I'm creating a site that is centered
around managing a team. The goal is to make a resource for parents and
fans to discuss the teams and athletes. It will mostly be a knock-off of
other blogs and forums, but it will provide some extra functionality for
whichever sport is being managed. So, stats, pictures and videos can be
uploaded. A schedule can be viewed (and managed by coaches). Coaches can
blog about the various events (matches, tournaments, etc.). And, users
can post in a forum (polls, regular forums).

The fun part - The site is struts 2.1.?-SNAPSHOT based using Maven,
Spring, Hibernate (JPA), SiteMesh, Acegi, and Prototype/JQuery (haven't
decided yet). I'm using the codebehind plugin and other than acegi, I've
hardly written any configuration at all! It's wonderful. The
breakthrough I had was that I've created something like 40 entities so
far and just began work on s2 actions. I was crossing my fingers that my
generic dao, codebehind and spring autowire would allow me to code by
convention and that things would work properly. Imagine my surprise when
I had my first action working in less than a few hours! When I'm done, I
may yank the guts out and post an integrated blog/forum project to
sourceforge as an example of s2/spring/sitemesh/jpa with hints of AJAX,
but that's a ways out...

Hi,

I've got a list with several items which are linked to a details-action.
If I klick on an item after the restart of the webapp a link like
http://.../details.action?id=123
is called. Everything is fine. I can see the correct details site.
When I go back and klick on another item (with another id)
the old id is called from the database and shown.

Within the action I've declared an
private String id;
with the getters and setters.
The logic (retrieval data from the database) is done in the execute
method.

Is there any caching or do I have to set id manually to null?
Or do I have to do the processing in the prepare-method?

Thanks for your help

Marc

Without any further info it's hard to say what the problem might be.

Actions are instantiated per-request, unless you've mis-configured a
Spring-defined action.

Depending on how you're creating the links (and how your application is laid
out) you may be getting URL parameters you're not expecting in your link;
<s:url...> has an "includeParams" attribute you might want to look at.

I'm sure there are more possibilities, but we might need more info in order
to help.

Dave

Hello Dave,

I've found a solution for that. The spring-action was standard-scoped
and in cause of that it didn't accept the
id parameter a second time.

I think it's a little bit strange that it's impossible to set an
property again when it's done before.

Marc

I'm not completely sure what you mean but two things come to mind:
- the s:action tag is useful for pages that need to be assembled using
the results from multiple actions. If each each outputs a component of
the view, you can uses Tiles or Sitemesh to assemble a page on the
server-side that invokes numerous actions. You can then reuse the
components and design actions around each data model instead of each page.
- as you're using ExtJS, you can use the same pattern as described
above, but invoke each action XHR. The page can be assembled via ExtJS
on the client-side with your actions returning data or html fragments as
appropriate.

struts-menu...
All right then, I'll try to follow the "using struts menu outside of Struts"
docmentation...
thanks, sassien

Your problem isn't OGNL in parameters, you are using EL in your
examples. By default, EL expressions are disabled, but you could easily
switch your expressions to OGNL. I'm guessing that if you use '%'
instead of '$' it will probably work. If your action has a getItem(),
and the returned object has a getId(), then %{item.id} should work, and
if the %{ and } may not even be necessary.

${ triggers EL expression parsing, but this is done by the app server,
if the TLD specifies that the attribute accepts EL (which struts tags do
not by default, unless you change the TLD which isn't advisable).

%{ forces OGNL expression. OGNL expression evaluation happens within the
tag's code, so the app server knows nothing about this step. Thus, the
TLD file's directives have nothing to do with this parsing. Many of the
Struts 2 tag's attributes will attempt to parse parameters as OGNL by
default, but %{ will force parsing.

In addition to Wes' comment, as you're using display:table and have used
the uid attribute, the current row of the table is placed into the
PageContext.

You can access the page context in OGNL via #attr, so your expression
becomes this:

<s:checkbox name="checkBox" id="checkBox" value="cdUsuario" fieldValue="%{#attr.item.id}" theme="simple" onclick="confirmAllChecked()" />
