Re: Formatting strings in Struts2/Freemarker

[Wes Wannemacher]

Have you tried to use a struts2 tag with OGNL? If I am understanding
correctly, you could use -

@s.property value="@[EMAIL PROTECTED]('OGNL.pathTo.variable')

Of course, I don't know freemarker, and this is assuming you can reach
the variable from OGNL.

*lol* Huge step off a short pier--I'm good at those.

Hmm, yeah, I didn't know about the lack of JSP tag
file support, but that's a good one to keep a handle
on, so thanks for the extra pursuit :)

On my list to add to the wiki.

Thank you for that. That was a huge step in the right direction.
However, that does not work.

freemarker.core.InvalidReferenceException: on line 4, column 146 in
template/xhtml/components/loginlink.ftl unitag.phone not found.


I found a snipped over on Freemarker's forum that says Freemarker does
not support some JSP 2.0 features. Bummer. That means this will
probably work if I just write a taglib instead. Or I have to wait
until they realease 2.3.11. Currently they are on 2.3.10...

Re: Formatting strings in Struts2/Freemarker

[Scott Kingdon]

If that works that would be great. I tried it, but maybe I am doing
something wrong.

In the JSP world, in order to use an el function you need to declair
it at the top of the page like this:

<%@ taglib prefix="uni" uri="UniFunctions" %>

When I put this at the top of a Freemarker page, it just gets printed
out to the page as text. So that does not work.

I tried declaring it in the JSP page before the freemarker template is
called. Then I called the el function like this in my template.ftl:

${uni:phone(session.USER.customer.phone)}

This spews out a nasty error. Freemarker complains that it does not
know what to do with uni:phone.

Re: Formatting strings in Struts2/Freemarker

[Dave Newton]

Since you can use any S2 tag inside a FreeMarker
template I guess I had assumed you could use the same
syntax to call static methods you can from JSP, does
that not work?

(AFAIK you can also expose the JSTL library to a
FreeMarker page but I'm not sure how the two ELs would
play together; w/ OGNL you can use the %{...} EL
escape.)

Re: Display tags within one line

[Jeromy Evans]

Hi Emi Lu,

The default struts2 tags use themes that determine how they are 
formatted as html[1].  The default theme 'xhtml' wraps each form input 
inside a table cell and prepends it with a label to the left or above.  
The css_xhtml theme uses the same layout with divs.


You have two options:
 - use the "simple" theme, which includes no formatting or labels but 
gives you complete control of the layout;

 - create your theme that sets out the layout you want.

The pages below are a good starting point.  It's seems common just use 
the simple theme, but if you want to create a lot of forms with similar 
layout creating your own theme can be worthwhile.


Hope that helps,
Jeromy Evans

Use . This will allow you to have 100% control
over the form html. Notice that by dong this you will have to handle
all the formatting of the table by yourself.

Formatting strings in Struts2/Freemarker

[Scott Kingdon]

I am very used to using JSP taglibs and el functions for formatting
text. In my current application I am using Struts2 with Freemarker as
the templating engine. I need to format a phone number that is pulled
from the database as 88 to be (888)888-. Using el
functions you can just call a static method from some class. This
would be nice since I already have that static method and it is used
elsewhere in the app.

I would use JSP for this, but our template is already built in
Freemarker. There are also come JSP pages that use this phone
formatter as well. Actually I have already created the el function tag
and have been using it all over in the app.

I have tried several things including trying to use el functions in
freemarker or even including JSP pages from freemarker.

Any ideas how this is done in the Struts2/Freemarker world? I am open
to any idea.

Re: S2 best location of application init params

[Jim Cushing]

If you're using Spring (and if you're not, now might be the time to consider 
it), I'd say make that a property of your application object that needs to 
configuration. That is, using your example, say you've got a class, 
TransactionLogger that needs "the home directory of the file system to which 
the application will write." Give it a property, loggingDirectory, and 
configure it with Spring, giving it a bean id of "transactionLogger". Then, add 
Struts 2's Spring plugin to your project (just include the JAR), define a 
method setTransactionLogger(), and Spring/Struts will automatically inject the 
TransactionLogger instance into your object. In your action, just call 
transactionLogger.logTransaction(foo), and there you go!

Among the benefit of this approach are: 
1.You can unit test your business object (TransactionLogger) without involving 
Struts at all
2. The business object could be re-used outside your Struts application
3. The configuration is only where it needs to be; in the business object 
itself. So you don't have to come up with some naming convention for your 
init-params, nor do you have to write tedious code to make the business object 
aware of the configuration. That is, TranscationLogger doesn't have to be tied 
to the Servlet API, nor do you have to write an initialization servlet that 
creates a TransactionLogger.

This ventures off-topic from Struts 2, which should probably be your goal: your 
business objects should not be tied to Struts or the Servlet API.

Re: S2 best location of application init params

[Wes Wannemacher]

There are two other options that I've used in the past... One is
Spring. You could create a custom bean or set of beans and initialize
them with Spring and use the spring plug-in to help get at those beans
any time you need them.

Spring is a big framework though and will add some complexity. The
other option, if you are hoping to keep from depending on the Servlet
API is a static initializer block. The problem with static blocks
though is that they can get out of control when you start adding them
to obscure classes. If you only have a small amount of lifting to do,
I would use a static block. The advantage is that it adds no external
dependencies which will make unit testing easy, but the disadvantage
is that it can become unwieldy.

If you are working on a large app, go with Spring, you may end up
using some of it's other features. For a small app with minimal
lifting, go with the static block. Of course, depending on the Servlet
API isn't all bad, so don't count it out unless you really need to.

Re: The breadcrumbs have been served!

Hey Emi Lu --

The breadcrumb plug-in keeps a trail of crumbs up to the max you specify.
If you want to clear it (or manipulate it in some way) at particular points
in your workflow, you can do that by requesting it from the session and
doing whatever you like.  The documentation reveals how it is stored in
session.

Re: The breadcrumbs have been served!

[Emi Lu]

Can you describe what logic you are looking for? 

> What sort of application are you working on?


Sorry, I did not know how the breadcrumb plug-in works.

I hope the demo of "http://www.strutsschool.com/"; is not the showcase of 
how the plug-in works.




The example shown by apache websites is the one I am looking for:

Apache Struts 2 Plugin Registry > Home > Breadcrumbs Plugin

When click home, the "Breadcrumbs Plugin" disappear.

However, in "http://www.strutsschool.com/";, the linkage never disappears.









For example, when user goes from home to page1 then to page 2, I would
expect showing

Home > Page1 > Page2



When Users go back to Page1, showing "Home > Page1"

When Users go to Home, showing "Home"

Is the new Breadcrumbs
plugin(http://cwiki.apache.org/S2PLUGINS/breadcrumbs-plugin.html)
supports the above feature already?

Re: The breadcrumbs have been served!

There is a slight issue with www.strutsschool.com (demo site for the 
breadcrumb plugin?).  


This breadcrumb never got cleaned.

For example, when user goes from home to page1 then to page 2, I would 
expect showing


   Home > Page1 > Page2



When Users go back to Page1, showing "Home > Page1"

When Users go to Home, showing "Home"

how about implementing the default initialisation parameters by placing the

S2: dynamic forwarding from Action class to external url

[Jiang, Jane (NIH/NCI) [C]]

I am also trying to forward my Action to an external report URL after
process the form. I tried to use redirect and it always prefix my URL
with my application context.  

I also tried to implement ServletResponseAware and use
response.sendRedirect().  It does not seem to do anything.  The default
result "success" is used when I return null from my Action.

Is there a way to redirect action to an external URL?

Make your Action implement ServletResponseAware, then just use the
response.sendRedirect() method to redirect to where you want to go.
Then return null from your action to let Struts 2 know that you've
handled things yourself.

S2 best location of application init params

[tom` frost]

I'm looking for the best place to put application init stuff.  I'm thinking
of something like the home directory of the file system to which the
application will write to.  What's the best way of apssing such information
in.  In the past I have used servlet api init params, but with all the
effort made in S2 to separate your code from Servlet api, surely there's a
better way.

Thanks,

[S2]Pass error message from called page back to calling page

[Justin Frost]

My situation is that I have an input jsp.  On submit I call my struts action
and do a DB query.  If I get an empty result I want to be directed back to
the original input jsp and display an error message.

What is considered the best method for doing this?

I could add the message to the session context.

On the "redirectAction" result type.


Personally I'd prefer this as the *default* behavior
and force you to specify if you *did* want "empty"

I agree, but I don't think the patch should change current behavior, 
just enable desired behavior.



This is probably more appropriately an XWork issue,
too, but it could be added to StrutsResultSupport (or
whatever that's called).


The patch I uploaded to the new JIRA issue (WW-2310) is against 
org.apache.struts2.dispatcher.ServletActionRedirectResult .


Since I've still not even migrated from 2.0.9 to 2.0.11 it'll be a while 
until I can benefit from this, but let's hope someone decides to test 
and commit it.

struts 2: data lost when switching from jsp1 to jsp2 and back

[hillybilly]

hi,
i'm new in struts2 (i did already a projekt with struts 1) and i cannot find
lot of support/tutorials in the internet.

until now, i like struts2 and the new improvements. but i'm stuck with this:

i have 2 forms, on form1 the user enters data and selects "actionA" which
directs him to form2. here the user enters additional data and clicks on
"actionB" which should direct him back to form1. in this case, all the data
in form1 that user entered before is lost. 
moreover, how can i access data from form2? do i have to save data in the
session (session.setAttribute) ??

in struts1, i used a formbean with scope=session, so this was no problem
here.

i'm confused! :)
please help me!

cheers,
   chris

Re: Creating and setting properties of collections

[Dave Newton]

Pardon the disheveled nature of this response :/

Whether or not the image object need to be "recreated"
is more an issue w/ your persistence mechanism, but
you'll at least need some sort of UID for each.

On the S2 side you can create a map keyed on the UID
and expose whatever properties you want (like an
object.metadata field or just a string or whatever)
and use map notation on your form.

Check out the wiki page on type conversion to see a
bit more about how maps can be used:

http://struts.apache.org/2.x/docs/type-conversion.html

It's down towards the bottom. In a nutshell you can do
something like (pseudotag):



where the map is:

Map _theMap;

with an appropriate getter.

On submission your map will be filled in w/ the form's
values, the next step depends a bit on your
persistence mechanism.

Sami and Alvaro:
if you want to contribute the Dojo 1.0 theme, then you probably file a
JIRA issue.
The simplest thing to do is creating a patch and attach it to the JIRA
issue itself.
You should create this patch against Struts 2 trunk (for 2.1.x
releases), where the Dojo theme is specified as a plugin:

Ah ok so you wanted to create an UI component!
I thought that you wanted to create a page layout, not a UI component: in

We should also update the wiki

I am using firebug and Venkman to debug. No requests are sent to get 
data for the list. After debugging the problem seems to be that the 
Struts comboBoxDataProvider's init method never gets called. This 
means the widget never loads data from the server. Every time the 
user edits the input field events are fired and the widget searches 
for data matching the input string. However since no data is loaded 
from the server no match is found and no autocomplete list is shown.


So the problem is with the data provider. Looking more carefully at 
the dojo.widget.ComboBox component the problem would seem to be that 
the 0.4.2 release of dojo is NOT the same as the one bundled with 
struts. There are significant differences in the dojo.ComboBox and 
data provider in the two versions. I've tried copying the dojo code 
included in the struts bundle to the dojo 0.4.2 release but the 
build fails.


Which is the dojo version that was used in the build of 
struts2-core-0.011.jar?

I'm not sure what is wrong, but the approach I'd take to debug it is:
 - Use firebug to see if the page is getting a 404 trying to load 
any of the resources required by dojo.  This is the most likely 
cause if it was working before you created the custom build
 - Replace your dojo.js file with the dojo.js-uncompressed.js file 
also created by the build process.  This one contains comments and 
debug info.  See if any errors are now displayed
 - Find the combobox code in dojo.js-uncompressed.js and use 
breakpoints in firebug to find out exactly what's happening.


Let me know how you go.

Re: dojo version in struts 2.0.11?

[Alvaro Sanchez-Mariscal]

Hi Sami,

My company (Salenda) is willing to contribute to get a
production-quality version.

Perhaps sharing source code in a cvs/subversion may be a good starting point.

Anybody else interested?

Alvaro.

Creating and setting properties of collections

[Mark Steyn]

Forgive me is this is a very obvious question, but I'm new to struts 2,
and despite googling around, I'm still not sure as to how to do
something.

I'm trying to accomplish the following:

1. Create a form which is used upload a zip file containing a number of
images
2. Upload and process those images, creating java objects and database
records for each.
3. Display a second form allowing the user to associate additional
metadata with the images 

I'm currently stumped on step 3.

I can upload the images and create objects representing them, and create
a form in a jsp allowing additional data to be associated with these
objects, but once that form is submitted, I'm not sure how to map the
posted data back to my image objects.  

>From what I gather, the image objects that were created in step 2 need
to be recreated in step 3, but I can't see an easy means of doing this.
Are type converters the best way forward, or is there a better
alternative?

Any assistance will be gratefully appreciated.

Mark

Re: dojo version in struts 2.0.11?

[Sami Dalouche]

If anyone is interested, I have created my own dojo 1.0.0 theme for
standard Struts 2 tags. (works on Dojo 2.0.11).

It's far from being *clean*, far from being complete, uses undocumented
attributes, but is a good starting guide to create progressive
JavaScript enhancement (falls back to pure HTML widgets if JS is not
enabled).

So, do not hesitate to drop me an email if you want to look at the code,
or plan to cleanly repackage it for Struts, it's available under
whatever open source license you prefer.

Sami Dalouche

RolesInterceptor. How to..?

[Filippov, Andrey]

Hi everybody!

I need to configure the login and authorization system in my application.  I 
have struts2 together with jboss and mysql. I found the following information 
about it:  
(http://struts.apache.org/2.x/struts2-core/apidocs/org/apache/struts2/interceptor/RolesInterceptor.html,
 http://struts.apache.org/2.0.11/docs/interceptors.html), 
http://www.vitarara.org/cms/struts_2_cookbook/creating_a_login_interceptor. 
As I understand the logic should be like this: from login.jsp get username and 
password, then get information about the user from mysql db (I mean confirming 
information about existence of the user and additional information about roles 
of the user), then put this information into session, then use RolesInterceptor 
to define access to the certain action. Am I right?
But I have not caught yet how could I put user object (see ref#3 - vitarara...) 
with information about login, password and roles (which are in the mysql db) 
into session?
 
RolesInterceptor class has the setAllowedRoles method. Could I use it to define 
a set of roles for user? How could I Do it? 
I appreciate any kind of help! Thanx a lot!!!


Sincerely yours,
Andrey V. Filippov

Re: Dojo custom build and Struts ComboBox widget

[Jeromy Evans]

Urgh... I was trying to create a build from the src in 2.0.9 as well 
without any progress.  Glad you solved it. 

Yes, please go ahead and update the wiki.  I was the original author of 
that page and that's why it's a wiki :-)

I have downloaded and created the custom build from the dojo 0.4.0

files i am pretty sure that 0.4.0 was the release used in the 
struts2.0.11, 2.0.10, 2.0.9 and 2.0.8 releases but it would be good if 
someone could confirm that.


We should also update the wiki

dojo version in struts 2.0.11?

[Jeromy Evans]

Does anyone know -exactly- which revision of dojo is bundled in Struts 
2.0.11?


A diff of the src dirs reveals it's not the tagged 0.4.2 release or 
tagged 0.4.3 release.  I believe it's near 0.4.2 but can't find a match.


The dojo plugin in Struts 2.1.x definitely uses the 0.4.3 tagged release.

Re: OGNL struts property

Horay! You are the first person to actually see and acknowledge the problem.
So far I have only recieved comments about the difference between the hash
and the non hash version - which I get. But no one has explained why in the
case of #2 OGNL returns null and not the value of the property as in #1.

Any one else know?

To quote another email:

Re: Dojo custom build and Struts ComboBox widget

[Max Pimm]

I am using firebug and Venkman to debug. No requests are sent to get 
data for the list. After debugging the problem seems to be that the 
Struts comboBoxDataProvider's init method never gets called. This means 
the widget never loads data from the server. Every time the user edits 
the input field events are fired and the widget searches for data 
matching the input string. However since no data is loaded from the 
server no match is found and no autocomplete list is shown.


So the problem is with the data provider. Looking more carefully at the 
dojo.widget.ComboBox component the problem would seem to be that the 
0.4.2 release of dojo is NOT the same as the one bundled with struts. 
There are significant differences in the dojo.ComboBox and data provider 
in the two versions. I've tried copying the dojo code included in the 
struts bundle to the dojo 0.4.2 release but the build fails.


Which is the dojo version that was used in the build of
