Hi,

This is a general design practice question.
Say if I am designing User Account Management component that does the
following:
1) User Profile info update -- updates firs name, last name, etc,...
2) Change password. -- do password verification, and change password
3) User Payment info update. -- add credit card info.

My question is, since these three function requires similar info from user,
how many action class should I use?
Should I use one: "UserAccountAction.java"?
or three actions: "UserProfileAction.java", "UserPasswordAction.java", and
"UserPaymentInfoAction.java"?


The approach I took is using one actions: "UserAccountAction".
But the problem is I created many properties and getters setters that are
not used for all struts action mappings.
So I am wondering if this is good practice or not, or should I break it into
three action classes.


How would you design this?

Any suggestion is welcome.
Thanks a lot!!

Personally I tend to use multiple actions, mostly to avoid having
unnecessary action properties. For me it's easier to deal with many
tightly-focused classes (as opposed to a small number of classes with
multiple responsibilities).

I don't think there's a right or wrong way, really--I just happen to
prefer keeping classes as light and lean as possible; they're easier for
me to read and understand that way. The negative is that I end up with a
lot of classes--but I'm okay with that.

Common functionality often gets broken out into super-classes. For
example a recent project now has a user admin action base class with a
bunch of services used across all user admin functionality, with a
number of sub-classes that handle specific tasks.

Bigger codespace, more lines of code. Lower cognitive overhead for each
class (although it's not always immediately obvious where shared
functionality is handled), more granularity making things easier to mock
and/or stub.

Ah, I miss Smalltalk.

This may be more related to XWork2, but I'll start by asking here.

I'm creating a custom Interceptor to handle user permissions for an application.
Rather than redirecting to an action to actually process a login attempt
(requiring a custom result type), the Interceptor itself will process the login
attempt. However, in order for this to work, the Interceptor needs access to a
session bean that is the interface to the persistence layer.

Is it possible to use the Java EE 5 @EJB annotation to inject an EJB, or even
the Inject EJB Plugin? I've tried both, and neither seem to work (both result
in a null object reference). I realize I can use a JNDI lookup to get a
reference to the bean, but I would much rather use injection if possible, as
that's why it's there.

Thanks!
-Nate

The short answer - You have to do the lookup yourself.

The long answer - There's a similar discussion going on that pretty
much covers the topic:

Yes, I'm familiar with this issue. I guess, in order to resolve it in an
Interceptor as opposed to an Action (the method of using an Interceptor and
reflection to do the injection), one would have to do the same for the
Interceptors...

Oh well, you can't win all of the time.

Thanks for the speedy reply!

Seems to me that my idea to create an ObjectFactory based plugin (rather than
the existing interceptor-based plugins) needs to pick up some steam. I only
have one question for the EJB users out there... Do you guys need Spring
integration as well? Currently, the spring plugin is the only plugin (I know
of) that is based on a replacement ObjectFactory. If you don't need Spring, I
could probably put one together pretty quick. If you need Spring, it would
take a little longer, or it could be a separate plugin...

To answer your question, _I_ personally don't need Spring integration. I've
never used Spring, and for this project, it was too much overhead to learn (on
top of Java EE, the JPA, Hibernate intricacies, Struts2...), and from what I
understand, it seemed like using it and S2 together provided duplicate
functionality (another topic altogether...).

On another note, I find it awesome that the community (or whatever group you're
part of) is so willing to provide support. I mean, in my eyes, this is
something that I could see myself writing to make my coding easier, it's just
that given my situation, it's easier to use the "workaround." Admittedly, I'm
not very familiar with JEE5. Some of this is still black magic, and I don't
fully understand the issue, I just know enough to understand that the
architecture permits it as an issue (and not everyone is just blowing smoke my
way) and can leave all of the intricate details be, as they don't directly
affect my project.

-Nate

uh? This is from the 2nd stack:

ParametersInterceptor.doIntercept(ActionInvocation) line: 187
ParametersInterceptor(MethodFilterInterceptor).intercept(ActionInvocation)

The default stack contains the static params interceptor.

Hi!
I would like to implement JASPER and my struts1 appliction

I have list of orders and items and I would like to use it .

I am new to JASPER. Does anyone know of an example for it?

Well, actually I am wrong about that and yes, if there is no "/", it
will use the namespace name:

if (!locationArg.startsWith("/")) {
       ActionContext ctx = invocation.getInvocationContext();
       HttpServletRequest req = (HttpServletRequest)
ctx.get(ServletActionContext.HTTP_REQUEST);
       String base = ResourceUtil.getResourceBase(req);
       locationArg = base + "/" + locationArg;
    }

"Hey you! Would you help me to carry the stone?" Pink Floyd

I am trying to "sell" the idea of using Struts 2 to my employer, and I
know these questions will come up:

1. Who is using it?
2. How does it perform, compared to plain servlets and jsps?
3. How well does it scale?
4. Has anyone benchmark it under load? numbers?

2-4 are somewhat related. I am sure many of you have gone through this
before, so if you can share some info with me I would appreciate it
(believe it or not I haven't built a production application with
struts 2 yet)

thanks

I could be wrong, but aren't quite a few Atlassian tools built with either
struts 2 or webwork? I remember a few months back Al Sutton worked on a high-
traffic site for selling Android Apps... http://andappstore.com ?

Also, wasn't roller moved to struts 2 a while ago? I think, if I remember
correctly, that means the blogs on http://blogs.sun.com/ are powered by
struts2. You might want to verify, but those are the ones I remember off the
top of my head.

IMO that's outside the purview of unit testing, though--by definition
this describes integration testing: the testing of an action along with
the framework.

There's nothing *wrong* with doing that testing, I just don't think it's
the same thing as unit testing: independently testing the smallest bits
of functionality.

JUnit can be used for that kind of testing too (and I do, sometimes),
but once I'm at that point I generally figure I might as well just be
doing client-focused testing and testing the output of my results. I
also use Selenium, although I may switch back to using a layer I wrote
on top of Watir.

Not to throw weight around, but it is sort of curious to me that the three
struts committers who chimed in all agreed that tip-to-tail integration
testing in JUnit is not worth the effort. I only bring it up because, IMO,
struts 2 is one of the best-unit-tested products I've ever worked on. I think
Dave, Musachy and myself are biased against tip-to-tail in JUnit because in
Struts 2, we have a guideline to unit test all bugfixes and new functionality.
That being so, all three of us have probably come across situations where
writing the unit test is 500x harder than writing the fix :)

Dave does a good job of making the point I tried to make earlier, tip-to-tail
testing is better looked at as an integration test and it becomes much easier
to deal with as an integration test. If you are unfamiliar with selenium, it
is worth learning. One of the posters earlier mentioned that he didn't want to
learn another testing framework when he already knows JUnit. Selenium is nice
because it runs right in the browser (IE and Firefox) and runs though a set of
VB-like instructions... Things like - open this url, look for this text, click
this link and then make sure this text exists. IMO, if you want to make sure
that your action renders the appropriate result, this is way better than
trying to coax the framework by bootstrapping it with mocks then figuring out a
way to retrieve the rendered result. As an added bonus, it is possible to get
maven to launch selenium tests, so you can get full unit and integration
testing out of your CI if you are willing to put forth the effort.

To drive the point home further, I would add that the Dojo plugin probably
would have been more stable if we had taken the selenium approach (that is
being employed with the slowly moving jquery plugin).

Hi all,
while i do selenium tests and i do prefer it for integration tests,
i'm feeling obligated to point out one disadvantage,
while being very easy and fun to write or record,
they tend to take a lot more time to run in comparison to unit tests.
My case is tons of selenium tests which takes about 45 minutes when
run in paralel.
But that's just my case which is very special,
i test whole stories on many apps at the same time.
On the pros side i have confidence that all my business processes are
doing well.

Best greetings,
Paweł Wielgus.

Hi,

I want to round a value during an interation:

------------------------------------------
<s:sort comparator="mapComparator" source="statsMap">
<s:iterator>
<tr>
 <td><s:property value="key.name" /><br>(Min: <s:property value="key.min"
/>, Max: <s:property value="key.max" />)</td>
 <td>
   <s:set name="average" value="value.average" />
   <%
     int val = 0;
   %>
   
   <s:property value="val" />
 </td>
</tr>
</s:iterator>
</s:sort>
------------------------------------------

As you can see, I iterate over a map. The value element of the map contains
a field named "averate". This average is a Float which I want to round
(Math.round()). I don't really know how to do that. I can find out how to
access the value from within <% %>. Once I have access to it, how can I
print that value? I never actually used <% %> tags.

Or ist there an easier way?

The whole idea if this code is to display ratings of serveral criteria where
a rating has a minimum value of key.min, a maximum of key.max and the
average rating is value.average. I want these values to be displays using
star icons. I am telling you this hoping there is a much easier way ;)

Maybe it will be better to prepare a list on server side with rounded
values and iterate over them?

I don't think so - I want the exact value to be shown, too, so it's more a UI
thing.

As you thing, but that's the business logic and even such simple
operation shouldn't be performed in UI. Maybe it will be simpler to
create TransferObject with original value and rounded value and put it
on the list.

Hi Robin,

 Select tag expects an list object in the list attribute but in your
case you are providing an Map that's why it is not behaving correctly.
I suggest create an object called UserType with two fields id and name. And
put these objects into a list (lets say usertypes). Now use following tag to
display a select box.

<s:select  name="userTypes" headerKey="-1" theme="ajax"
 
headerValue="-- Please Select --" list="#application.usertypes" listKey="id"
listValue="name" label="Select User Type"/>

Hope it will help you.

Regards,

Nitesh Jain

Subject: Freemarker and Select Tag

Hello,

Platform : Struts 2, EJB 3.0, Glassfish 2.1

I'm having trouble using the Freemarker equivalent of the JSP Struts 2
Select Tag.

I need to convert:

<s:select list="application.userTypes" />

into the Freemarker equivalent.

userTypes is an application defined attribute. I have checked the
existence of the attribute within the page and it is shown as expected.

My List/Map is defined as

    Map<Integer, String> userTypes = new HashMap<Integer, String>();
    userTypes.put(1, "AGENCY_USER");
    userTypes.put(2, "SHOP_USER");
    userTypes.put(3, "TOUR_OPERATOR_USER");

I have tried the following, none of which work (or work correclty).

<@(protected)
the select box, but are valued as 1=AGENCY_USER, 2=SHOP_USER

The following produce empty select boxes (or errors)

<@(protected)"/>

<@(protected)}"/>

Does anybody have any ideas ?

Thanks

Hi,

 I have also implemented login mechanism but I have used Servlet
filter to check the user login status.
I have applied filer on the restricted URI of my application by just a small
configuration in web.xml.

Subject: Re: Login with Struts2

Hi,

I recently implemented a login mechanism but did it slightly differently
after recommendations from this mailing list to use an interceptor.

Each action/page that requires a validated login is directed via a
Interceptor.

The sole purpose of the interceptor is to verify the existence of an
object in the session. Here is the guts of the method:

  public String intercept(ActionInvocation invocation) throws Exception {
   
    ActionContext ac = invocation.getInvocationContext();
    Map session = ac.getSession();
   
    // retrieve the login status from the session by key name.
    User user = (User) session.get(Constants.USER_SESSION_SCOPE);
   
    // if the user object is non null, the user is logged in.
    if (user != null) {;
       return invocation.invoke();
    }
       
    return "notLoggedIn";
  }

It is then necessary to create a new interceptor stack:

       <interceptor-stack name="my.validationWorkflowStack">
     
          <interceptor-ref name="defaultStack"/>
          <interceptor-ref name="amr.validation"/>
         
       </interceptor-stack>

I also defined a global-result as follows to take care of directing the
client when not logged in.

    <global-results>
       <result name="notLoggedIn" type="redirectAction">
          <param name="actionName">showLogin</param>
       </result>
    </global-results>

Finally, here is an example of a protected action using the new
interceptor stack:

    <action name="showControlPanel">
   
       <!-- Include our validation stack to ensure user is logged
in -->
       <interceptor-ref name="my.validationWorkflowStack"/>
     
       <result type="freemarker">/controlPanel.ftl</result>
    </action>

You then simply need a regular action to take of the "login" which will
place a valid object/flag in the session.

Hope this helps
