That part is normal; some tests expect to create exceptions.

So, here's what I've managed so far...

I "installed" my local xwork build jar, almost like the directions say to, but 
*additionally* installed it removing the "-Dclassifier=sources".

This worked (whether or not it's right) but now I get a build error when 
compiling the struts-annotations from 1.0.4-SNAPSHOT.jar.

It was all working quite recently, too.

lol! the same here, more than two years using MyEclipse and did never
realized I could debug JSP, indeed a very good thing that we haven't had any
strong need for it when using (correctly) Struts 2 :)

Struts Validator Framework: client-side validation problem with submitting buttons

[cacodemon79]

Hi, I'm using Struts Validator Framework (Struts 1.3).
Server-side validation works well.
The problem is in client-side validation.

The form name I have to validate is: RegistrazioneUtenteForm.

In my jsp page I have 2 buttons:
1) 
2) 
and the following form declaration:

Moreover I have enabled javascript validation:


The javascript function submitRegistrazioneUtenteForm is the following:
function submitRegistrazioneUtenteForm(nomeForm){
eval("document."+nomeForm+".submit()");
}

If I click on the second button (html:submit), all works well (I get
javascript alerts).
If I click on the first button (html:link), the form is submitted but I
can't see any javascript alerts.

I can't understand where is the problem.

Can you help me?

Thanks in advance.

Re: Error replicating sessions with Struts 2 framework java application

[Dave Newton]

Clustering is generally framework-neutral--it's straight JEE as far as I know. 
As long as the session is serializable (hey, thanks a lot, subList :( it should 
work no matter what the framework is.

We're running S2 clustered with no issues.

Re: Error replicating sessions with Struts 2 framework java application

[Al Sutton]

Just to add to this, S2 is compliant with J2EE specs, therefore if the 
container has problems clusting a S2 application, it's not S2 that's at 
fault, it's the clustering capability of the appserver.


My guess is that youy need to look at the information replication 
strategy employed by your chosen app server, you may find the app server 
vendor has some notes about the reliability and replication latency for 
the available strategies.


Al.

P.S. About the mail in the link; I'm not sure what comment is 
neccessary, check the code mentioned and see for yourself how it's 
implemented.

struts2: render JSP from action class

[Esteve Camps Chust]

hi all,

this is my first email at struts list. I am a new user to struts2. I'm
trying to get working the next scenario: having a mailer class, I want the
message text be a rendered JSP. The action class calls a mailer class; this
composes the mail from the rendering result of a jsp element (it would be
fantastic that this rendering process uses some action class
attributes/values). Finally, the action class informs the user about the
mailing result.

Is there any way to get this working? I think I did it once on struts 1.3 :(

Thanks in advance.

Sincerely,

Esteve

Yes.

cd sandbox/struts-convention-plugin && mvn clean install

You'll then be able to use struts-convention-plugin-2.1.3-SNAPSHOT in

You may need to ensure the sandbox, struts2, xwork and

WOW.. The convention plugin rocks! I like it!
I'm writing action classes and related jsps and struts finds the
right Action class and jsp without having to touch the struts.xml
I don't even have the struts.xml file!

This is a very confortable way of writing web applications.


It works with Tiles, but you have to explicitly declare each 
@Result(type=TilesResult.class,value="xxx") which I find really annoying 
(as you say, it breaks the convenience of the convention).  I've been 
intending to raise that over at struts-dev, which I'll do now.


Yes.. Please do. If it would support tiles, I'd start using
it right away, but like this, no way.

I don't like the idea of having to define result mappings in java
source code.. and to say it all.. I don't like annotations,

Re: [OT] What slows you down?

[Greg Lindholm]

When I read this I was being slowed down by constant stopping 
and starting of Tomcat from within Eclipse...  
  - make a change in an action class
  - start tomcat
  - test it... not working
  - stop tomcat
  - make a java change 
  - repeat

In this case I was working on validation logic with annotations.
How else do you test validation logic? Can you unit test validation 
logic? Is there a better way? [1]

Part of this problem was I wasn't sure if my OGNL expression was correct.
How do you test/debug OGNL expressions when they will depend on 
the ValueStack? [2]

Another part of the problem is the doc for FieldExpressionValidator doesn't 
bother to tell you which direction (true or false) the expression should 
return to pass or fail the validation. [3]

BTW: I really really like Struts 2.  Over the years I've went from Struts 1, 
to JSF, and now Struts 2, and S2 is by far the best and easiest and 
most enjoyable.  

The thing that slowed me down the most was the learning curve.  I started
with
the online tutorials, and the "Starting Struts 2"  pdf book, then I had to
start 
working on my application.  It was very rough going at first, I spent a lot
of time 
in the debugger trying to figure out what the hell was going on.  Then I
read 
"Struts 2 Design and Programming" and felt better, went back and fixed some 
of the bad designs I started with but still was lacking much knowledge. 
Finally 
"Struts 2 in Action" was released and I got time to read it **.  
I finally feel comfortable, and figure I understand how Struts 2 really
works. 
Now I'm going back again and fixing more early bad designs. [4]

One more, un-versioned online documentation. 
Under the URL http://struts.apache.org/2.0.11.1/docs  (which anyone would 
reasonably believe is documentation for Struts 2.0.11) is documentation that 
only applies to release 2.1.x.  More then a couple of times I've had a
problem 
searched for a solution found it in the 2.0.11.1 docs started implementing
it 
only to discover it was only for 2.1.x. (very frustrating.) [5] 

[1] Unit testing validation logic
[2] Debugging OGNL expressions
[3] Poor or incomplete documentation, lack or real-world examples and use
cases
[4] Learning curve
[5] Un-versioned docs.

** Struts 2 in Action is a really good book, highly recommend it. However, I 
don't think I would have got nearly as much out of it if I hadn't already
gone 
through the other books and hand's on struggles before I read it.
