Re: Confused about upgrading Apache Struts

[Alex Choi]

Hi Sean,

Maybe I can help explain what you're about to undertake from a SysAdmin
prospective.

Upgrading or changing an application framework like Struts is similar to
upgrading or changing a Linus/Unix pplication package or dependancies.  In
Windows, it would be similar to upgrading or changing DLLs.

In those cases, APIs, application  structures, processing flows, and so-on
may have changed.  If any of these items have changed, then the application
may need to change too.

A starting point is the reviewing the framework's documentation, change
logs, applications technical documentation and so-on.  As Dave mention
before, if you need help with understanding these documents you should
consult with the application developers or your application vendor.

I hope this helps.

Alex

Hello David

Thank you for the reply.  Is it difficult for a Linux Admin who is a
non-developer to upgrade struts by themselves?

Re: Confused about upgrading Apache Struts

[David Greene]

Struts is a MVC framework for a web application.  That application needs to
be modified to use different version of the Struts2 library and depending
on what version you're currently running, you may have many changes to make
on the application's end.

If that application is owned by your company, hire a Java dev to do this
work for you.  Save yourself the headache.

If that application is owned by another company and your company
bought/contracted/etc that application, contact the vendor and ask them
about when they'll patch their software appropriately.

Other than that, there's documents here to help:

Just add something like the following to the methods that execute before JSP

Re: Confused by Result-generation

[Stephan Schröder]

Ok, i found the answer with debugging
DefaultActionInvocation.invoke()-method. It's the first case even if one
interceptor doesn't call actionInvocation.invoke(). In that case the result
is generated surrounded by all of the previous interceptors.

If all (e.g.2) interceptors call actionInvocation.invoke() you get this
call-sequence: 
Interceptor 1- Interceptor 2- Action- Result- Interceptor 2-
Interceptor 1

If one (e.g. the second) interceptor doesn't call actionInvocation.invoke()
you get:
Interceptor 1- Interceptor 2- Result- Interceptor 1

There's some tricky use of recursion.

Regards,
Stephan

 hi,
 
 as far as i understand it, the calling sequenze of an action mapping looks
 like this:
 Interceptor 1- Interceptor 2-...- Action- Result-...- Interceptor
 2- Interceptor 1
 (see http://struts.apache.org/2.0.11.2/docs/big-picture.html)
 
 But what happens when i use this AuthenticationInterceptor:
 
 public class AuthenticationInterceptor extends AbstractInterceptor {
 
   public String intercept( ActionInvocation actionInvocation ) throws
 Exception
   {
 Map session = actionInvocation.getInvocationContext().getSession();
 User user = (User) session.get( Struts2PortfolioConstants.USER );
 if (user == null) {
   return Action.LOGIN;
 }
 else {
   (( UserAwareAction ) actionInvocation.getAction()).setUser(user);
   return actionInvocation.invoke();
 }
   }
 
 }
 This is adapted from Struts 2 in Action and it looks like here the
 calling sequence would be
 Interceptor 1- AuthenticationInterceptor- Interceptor 1- Result
 
 So in the normal case the Result is generated within the Interceptors
 while the second code suggests that the Result is generated aber the last
 Interceptor has returned.
 Or is both true?

 Stephan

The Include tag creates a javax.servlet.RequestDispatcher and performs 
an include operation [1].  The tag attempts to create a reference to the 
resource provided as a parameter based on the current servlet path.  It 
should be able to invoke an action if the Struts2 Filter sees that 
include request. 

The Action tag creates a struts ActionInvocation based on your 
Configuration and invokes it as accessed via the Filter (through all the 
interceptors). It can invoke any action but be wary that the 
ActionContext is stored in a ThreadLocal (not saved and restored after 
an invocation) and not all results can be safely executed within another 
page.


Hope that helps,

Re: confused with redirects

[James Mitchell]

;)  I thought so.


So, all the following are true:
 - you are testing this on your local machine (your browser is  
hitting your own machine)
 - you have enabled cookies on your machine (if not, make sure all  
urls are rewritten correctly, before you click on them)

 - you have a global forward named welcome
 - welcome goes to a jsp page with links that, when clicked,
   will take the user to (for instance) /yourapp/PopulateUserInfo.do
 - you know for a fact that this action is being called because you
a) added a few print statements
  or
b) you set a breakpoint and watched the debugger step through it
 - this action returns an ActionForward that will go to UserInfo.jsp
 - you know for a fact that UserInfo.jsp is the path for the  
returned ActionForward because:

a) added a few print statements
  or
b) you set a breakpoint and watched the debugger step through it

If you are not hitting your own machine, make sure there isn't a  
proxy or something that might be rewriting the request headers or  
screwing with the cookies in any way.


If all the above are true, make sure:
 - you do not have any filters or listeners intercepting the request  
and changing/wrapping/hijacking/etc


Sorry for the flood of if/else, but without sitting behind you are  
watching what you are doing, this is the best I can offer.

I'm not sure I really understand your problem description, but it
*sounds* like the browser is making a request to the application context root 
during rendering of the intended page.

A common cause for that is an img tag's src attribute, or some other URL in 
the page, pointing to '#' or '#something' -- e.g. img src=#/. 
Check your rendered HTML for stray references to resources (images, 
stylesheets, etc).

RE: [To sum it up] Re: Confused

[Daniel Perry]

I took one look at ejbs and ran a mile.

Struts and EJBs seem to be at the opposite end of a scale.
Struts is sensible, nice to work with, efficient, and generally everything
that EJBs arnt!

I personally use it with OJB (made that decision 1.5 yrs ago).  Hibernate
seems to be more popular, and if i was to make the decision now, i'd
probably go with hibernate.  I'm sticking with OJB in the systems i have
because refactoring the whole lot would be such a chore, and OJB works fine
(though i have had to deal with some really annoying intermittent bugs).

Daniel.

Spring takes care of all this (http://springframework.org) without the overhead 
of an ejb container.

Acegi is one aspect closely tied to spring that takes care of security 
declaratively.

Hello all,
Sorry to get into this thread so late...
Since I have same view as Daniel about Hibernate/EJBs, I wanted to ask
one additional
question, since right now I am using EJBs..

Now, EJBs have some features that let the coder concentrate only
On the business logic instead of dealing, for example, with
synchronization, transaction, threading ..and security, meaning that you
can declare in the
Deployment descriptor which roles are allowed to do what with your EJBs.

Where can you do the same with ORM tools?  In the web layer?
Or do you have to have a security framework in place (such as acegi)?

Thanx and regards
Marco

[OT] Re: [To sum it up] Re: Confused / one little question

[Radu Badita]

In fact, this thread was really about Struts and how it integrates with 
various J2EE technologies and containers, not about Hibernate/EJBs...
Anyway: I don't think that anyone says that Hibernate is better than EJB 
period; but maybe easier and more flexible to use than Entity EJBs CMP, 
which is just one of the species of EJBs.
It is true that EJB (entity beans or not) has these nice features you 
mention: declarative transactions and declarative security (multi 
threading and synchronization are in fact container and coding 
related, and also implemented by Hibernate), BUT the question is: are 
those really necessary?
Hibernate also supports CMT, and, if facaded by SessionBeans (which is a 
very common scenario and is also recomanded for entity beans), you have 
declarative transactions.
Security is a very nice feature, but in scenarios where you only use a 
web application to access the EJBs, and the EJB container is isolated 
from the rest of the world, it becomes either useless, or a burdain to 
use... And I think that this scenario is the most common (especially 
among the subscribers to a list such as Struts Users :)
It's also true that in some scenarios the Entity Beans might be more 
effective than using an ORM such as Hibernate, but these scenarios are 
extremely rare...
Also, even Hibernate is sometimes regarded as being too complicated and 
too hard to learn by some (it was a very hot discussion about this on 
this list), and in even simpler scenarios are preferred even simpler 
tools such as iBatis, ORB, etc..
In my opinion, a discussion with a subject such as EJB is better than 
Hibernate is completely meaningless... The right tool always depends on 
the job, and the right tool for every imaginable job was just not yet 
invented.  :-)
The answer to your last question IMHO is: yes, you can, if the web layer 
is the only thing accessing your beans. But the subject of security is 
much more complicated in a real-life application than what framework do 
I need to best implement it?


You're welcome,
Radu

No,
J2EE is a NOT EJBS!
J2EE is a collection of technologies, including servlets, jsp, EJBs, etc.

Tomcat hosts various parts of J2EE - servlets, jsps, etc, but it is not a
full J2EE container - it doesnt host EJBs. But you can use servlets, JSP and
taglibs without using EJBs. I do. I've never used an EJB.

[To sum it up] Re: Confused

[Stéphane Zuckerman]

Hello Pierre,



Struts is just too big a project to stay among its siblings under the 
Jakarta general project, which is why it is on its own.


I have just installed Tomcat 5 for Java WSDP. Do I need this version  to 
make Struts development or can I use the regular 5.5 version too?  I 
have installed both.


If you use JBoss, there is an embedded version of Tomcat 5 with it. You 
don't need anything else.


Also, I would like to know how can I have access to J2EE? I am on Mac  
OS 10.4 and as I know I need JBoss to have access to J2EE. 


If you use JBoss to do your work, that's fine : it works great. Just 
don't forget to put your webapp in the 
$JBOSS_DIR/server/{default,minimal,all}/deploy directory (either as a 
WAR archive, or as a yourapp.war directory).

For instance, I use the default server, that leads to a path like :

C:\jboss\jboss-4.0.1\server\default\deploy\my_webapp.war

(I am currently using MS-Windows for my devs)

I have  
installed JBoss on my machine too. But I don't understand how can I  use 
Tomcat, JBoss and Struts altogether. Can you help me?


Struts is a collection of Java packages that you must embed with your 
web application.


You must understand how a J2EE application is built (which is a bit 
beyond the scope of this mailing list, I think). Basically, this means 
your application will have the following structure :


+---WEB-INF
|  +-classes
|  +-lib
|
|
+---META-INF

WEB-INF contains configuration files (such as web.xml, and 
struts-config.xml), definition files (for instance the taglib definition 
files), etc. ; its subdirectories contain the various compiled classes 
(the classes directory ;-) ), and the various packages you hava to 
embed with your application (for instance, struts.jar ;-) ).


Anyway, this little presentation is far from complete, and I suggest you 
read some doc about J2EE applications before going further with struts 
(java.sun.com is a good start).

Re: Confused

Pierre,

Struts is no longer a sub-project of Jakarta but is now on its own.
Struts is alive and kicking: http://struts.apache.org/

You can look at section 6 [this might help]: 
http://struts.apache.org/userGuide/index.html

As for JBoss... the last time I used it (can't exactly remember when)... 
JBoss has a version that is already bundled with Tomcat.

As for the Mac, I cannot really help.

Hello,

I am new to Struts and I am a bit confused. I would like some light.

I have just installed Tomcat 5 for Java WSDP. Do I need this version 
to make Struts development or can I use the regular 5.5 version too? 
I have installed both.

I also saw that Struts is listed in the Ex-Jakarta section of the 
Jakarta web site. Is this mean that Struts is now replaced by Tapestry?

Also, I would like to know how can I have access to J2EE? I am on Mac 
OS 10.4 and as I know I need JBoss to have access to J2EE. I have 
installed JBoss on my machine too. But I don't understand how can I

Thank you Geeta, I will give this a try.
If anyone could shed some light on exactly what these tags are doing

how to change those, when should you, etc.), I would appreciate it. 
Otherwise, I guess I'll get into the source when I have time.

Subject: Confused about ActionMessages
Hello all.
I have successfully used ActionErrors in combination with the 
html:errors tag, by adding errors under various keys and then simply 
placing the html:errors/ tag at the top of my JSP.

However, the ActionMessages class doesn't seem to act in 
parallel to the 
ActionErrors class, and neither does the html:messages tag 
seem to act 
just like the html:errors tag (for one, it has a required 
attribute that 
the docs don't explain very well). And I sure don't 
understand all these 
constants (GLOBAL_ERROR, ERROR_KEY, MESSAGE, ACTION_MESSAGE, etc). 
What's for what?

Could someone please give me a quick and dirty example of using 
ActionMessages to present a Your data was saved or similar 
message on 
the success page after a form action is processed?

In other words, could you show me how you are populating the 
ActionMessages instance in your Action class, and then how you are 
displaying the messages on your JSP?

You'll really be helping me out as I'm trying to show my client some 
working pages soon! (I don't wanna cheat if I don't have to).

Thanks,
Erik
