[S2] Testing if session variable is present
Hi,
I need to test in jsp if some session variable is present, and based on that
to
show some struts view code or not. How can I do that ?

Thx, Milan

Hi Milan,
If you're using Struts 1 you should be able to use the logic:present tag
like this:
<logic:present name = "NameOfVariableSavedInSession" scope = "session">
<tags to execute if the above is true....
</logic:present>
Hope this helps!

You may access your session variable just like you would do without S2. There
is no difference. Then use either the s:test tag from struts or c:if from the
standard tag library.

Hi Dave,
one question, is it possible that Acegi security remove my session variable,
because it sometimes ask to login between actions ? But, I'm not sure for
this.

I still don't know, because you still didn't include the code I asked for. That would have saved at least one posting (this one).
I duplicated your scenario, except for that whole "mine works" thing. I store things in session all the time and have never seen this issue (except one time when our replication wasn't working properly, which isn't a Struts issue).
I know of no default mechanism that would remove a session variable without being told to do so. Unless you provide more information it's unlikely you will get any replies that will magically solve your problem.

Yes, that's exactly what that does. It invalidates the session and removes
all the data.

If your artifacts are that big, I suggest that you create a minimal
example that reproduces your error and then provide us with those as
examples. Otherwise, it's impossible to help. And who knows, maybe the
little example works, and then we can rule out Struts 2 in the
equation.

Testing if session variable is present
Posted by Milan Milanovic <mi...@yahoo.com>.
Well, actually no.
I work through my application 30 mins. with my session o.k., but when I came
to redirect action it dissapear. I will create test application with nearly
empty action class and jsp-s to try if redirect action
to another namespace really delete session, as it happes to me. I checked
this with log, variable is here, user click on redirect link, after showing
resulting jsp, there is no any variable in session. And what is interesting,
Acegi doesn't ask for login, so not whole session is deleted, only variables
I set in Struts action class.

Is it possible you have the server session-time-to-live set to a very small
duration of time? This might explain why the sessions are disappearing.

Thanks huricane Dave ;-).
O.K. I'll check everything one more time. I'm using only default stack and
it worked until now good. And I fixed that "invalidate" problem, so I don't
invalidate nor clear session anywhere in my project.

NO.
There is no mechanism in S2 that arbitrarily removes session variables. The "redirectAction" result don't do anything to the session at all. In fact, very little does anything with the session at all.
Look at the S2 code. Since you're not going to help us help you, you're going to have to help yourself. All the code is available. Step through it if you have to. Read the documentation of any code you use that might involve the session; not knowing what session.invalidate() does leads me to believe you haven't spent much time with the Javadocs. Check your interceptor stack and interceptor configuration. If you don't want to step through code, add an interceptor that tracks session variables and see if an interceptor is removing it.

RedirectAction is not the culprit, AFAICT, from the information you've provided.

Ahhhh Medusa code. So named because anyone who looks at it gets so
petrified they turn to freeze up and turn to stone.
I once worked for a company where one of their classes was about 200K in
size, the reason was the developer thought that in every you needed to
catch every exception thrown, wrap it in something else, and re-throw it.
Laugh... I laughed so hard I almost peed in my pants when I saw it. (and
yes, the company was dumb enough to pay an expensive contractor to
"optimize" the code. he corrected the exception handling, which reduced
the code size and sped things up slighly, for which he got glowing
praise by the management).

Captin... The cyclometric complexity meter is at max... I canne give it
any more.
Reflection can seriously help with big else-ifs. If your switching on a
variable use the variable name and value as part of the class name and
then do;
Class blahHandlerClass = Class.forName( "BlahHandlerFor"+value );
BlahHandler blahHandler = blahHandlerClass.newInstance();
blahHandler.doYourWork();
It splits your code into more manageable chunks, allows you to add
handlers for new values without touching the motherload, and it makes it
look like you're a java ninja blending in with the workplace :).

Session handling is no different for a redirectAction than any other result (more or less).
The advice to write a test application that reproduces the error was good advice--without it it will even *more* difficult to help you.

I refer you to the answer on sessions I gave you some emails ago.
You **REALLY** should read how session work. They are not passed through
a servlet.

I know that they are passed through serlvet, I'm just wondering if struts
makes some error there.
Could you be positive that Struts 2.0.11.1 doesn't do anything with session,
i.e., session remains
intact and session is set for folowing action in case of redirect action ?

Testing if session variable is present
Posted by Al Sutton <al...@alsutton.com>.
Milan,
Please read up on how sessions work. They are NOT passed via URLs unless
you have cookies disabled, URL rewriting enabled on your appserver, and
a very sick sense of what a normal configuration is.

Hi Dave,
one short question, don't be angry ;-).
The link which when clicked action class lost its session looks like this:
http://localhost:8080/myproject/show.action?dojo.preventCache=1224214242324&id=4
Is it possible that session is not passed through this link ?

We have a 1M class where I'm at now. That's *1M* of source. 30k+ lines, mostly if-elseif.
It broke our cyclometric complexity meter, had to put in a bigger fuse. It makes Eclipse cry. It makes *me* cry. Kinda like this thread.

Seriously, refactor your code. 5K lines of code in 7 files could hide
all manner of nasties.

O.K. Thanks.
I must see why my session is deleted when redirect action is called :-(. I
checked everything 10 times, and I don't anything with session, so it is
very wierd to me why it is removed after just one click.

Answer : No
Only your code and your site design will affect the session variables
you have set and whether they are accessible.

redirect action delete session or variables in it or maybe not pass some,
because they after redirecting I don't have that variable in session ?

If you can't give us the code, we aren't able to help you.
Session's don't need to be passed between actions. They are managed by the
servlet container. But it is pretty safe to assume that Struts2 is not
destroying your session.

:O imho first stop would be someone who will refactor them.
5 jsps and 2 classes with 5K lines of code is not a healthy program.
Once they have been refactored you may find it easier to find the problem.

Just making sure hurricane Dave doesn't blow through the list.
If you ask for help, and someone offers, give them what they ask for.
They can always ask for a translation of bits that may be critical, but
unless you've rewritten large chunks of the JVM and Struts your tags and
code will still be understandable.

I already gave you my action configuration:
<action name="show" class="mySecondAction">
<!-- Redirect to another namespace -->
<result type="redirect-action">
show
/actions
true
${id}
</result>
</action>
and here it is how it is called from jsp:
<s:url id="connectUrl" action="show">
s:param name="id" value="id" />
</s:url>
<s:a id="d_%{id}" href="%{connectUrl}">Show</s:a>

Al ?!
Dave, I cannot give you all that info, because of two things, first my
classes
and jsp-s are pretty complex, and not in english! So, I narrowed my scenario
to this, my variable is in session -> when redirect action is clicked, there
is no
variable in session any more! It's seems like that redirect action doesn't
pass
or set session to another action class.

Dave,
Repeat after me;
It's Friday. It's nearly the weekend. And if they don't give me what I
want I'm going to take my toys away and stop playing :).

Yes, I understand. But I don't remove session variable or call invalidate
anymore, and when my variable is stored during the whole scenario and when I
click to this redirect I get lost of my variable.

As I've said, I know of no default S2 mechanism that would arbitrarily remove session variables. As I've also said, and as the documentation clearly states, and as you were told on the Spring forum, if you're calling session.invalidate() you'll lose all your session variables.

O.K. Thanks.
One more question, is it possible that my session variable is erased when I
redirect
to another action/namespace, like this:
<action name="show" class="mySecondAction">
<!-- Redirect to another namespace -->
<result type="redirect-action">
show
/actions
true
${id}
</result>
</action>
?

It should be used when you want to invalidate the session and remove all objects in the session.

As you can see, I've read it, conclude it and write here, if I didn't I'll
still have a problem, isn't it ?!
I have asked in which cases this method should be used ?

You're asking if session.invalidate() will erase the session? Really?
Here's the thought process I'd use to figure that out, step-by-step.
Step 1: Read the Javadoc.
That's all the steps, because the Javadocs say the following:
"Invalidates this session then unbinds any objects bound to it."
So I'm guessing that yes, calling session.invalidate() could actually invalidate the session.

Hi Dave,
excuse me for disturbing this list or you personally, I asked for this in
Spring forum (
http://forum.springframework.org/showthread.php?p=194333#post194333
http://forum.springframework.org/showthread.php?p=194333#post194333 ).
I figured out what I do in those method with session which forces user to
log in again, that I don't do in other methods, I do this:
// Test if session is valid
if (session instanceof org.apache.struts2.dispatcher.SessionMap) {
try {
((org.apache.struts2.dispatcher.SessionMap)session ).invalidate();
} catch (IllegalStateException e) {
logger.error("Session is not valid!", e);
return Action.ERROR;
}
}
Is this possible to erase session ?

I already told you I don't know and you continue to refuse to provide the information I've asked for. You also added new information about Acegi, which I responded to by saying that yes, if you're getting logged out it's unlikely you'd keep the same session, as that would somewhat defeat the purpose of any reasonable login/logout mechanism.
I don't think I have anything further of value to offer you. I don't know of any issues with session variables; if you're having an Acegi issue then pursue the issue on a Spring forum.

Dear Dave,
O.K. But when you look at this scenario:
MyFirstActionClass -> show first.jsp -> user click on link ->
MyFirstActionClass.method where I set session variable
(getSession().put("variable", new Boolean(true)); -> show second.jsp (here I
see my variable) -> user click on some link ->
MySecondActionClass.method->third.jsp (here I don't see my variable).
I should note that in MySecondActionClass.method I don't clear session or
something similar, I just add remove some other variables and set some new.
Why my session is obviously cleared when action from another namespace is
called ?

Hi Dave,

Use Boolean.TRUE rather than instantiating a new object.
Note also that the Javadocs for Boolean state in big bold letters:
"Note: It is rarely appropriate to use this constructor. Unless a new instance is required, the static factory valueOf(boolean) is generally a better choice. It is likely to yield significantly better space and time performance."

Re: [S2] Testing if session variable is present
Posted by Milan Milanovic <mi...@yahoo.com>.
It seems that my session variable is deleted somehow when first action method
of the second Action class is called:
MyFirstActionClass -> show first.jsp -> user click on link ->
MyFirstActionClass.method where I set session variable
(getSession().put("variable", new Boolean(true)); -> show second.jsp (here I
see my variable) -> user click on some link ->
MySecondActionClass.method->third.jsp (here I don't see my variable).
I should note that in MySecondActionClass.method I don't clear session or
something similar, I just add remove some other variables and set some new.

Yes, I tried with this, but session variable is not found.
I think that you didn't understand what is my scenario. I have implemented
SessionAware interface for both of my action classes and that works
perfectly in the case of jsp's that are connected to that classes.
But in this case, I have this:
MyFirstActionClass -> show first.jsp -> user click on link ->
MyFirstActionClass.method where I set session variable
(getSession().put("variable"); -> show second.jsp -> user click on some link
-> MySecondActionClass.method is called to return some results -> show
third.jsp with those results, and in this page I test if my session.variable
is present, but there is not !! But, my variables that are set in
MySecondActionClass.method are present in session for third.jsp!
What is the problem ?

That's one explanation.
>> So, scenario is like this:
>> [...]
I am unable to duplicate the inability to test session variables for non-existence/null.
If I have an action implementing SessionAware (properly), set "foo1" into session, and do not set "foo2" into session, the following tests work:
<s:if test="#session.foo1 == null">
...
<s:if test="#session.foo2 != null">
...
They continue to work if I go through multiple actions using the exact same JSP to test for their presence/non-presence.
It is likely you are doing something wrong. I suppose that means you'll need to post the relevant SessionAware implementation, the code that sets the session variable(s), any action code in the application path that could modify session variables, the JSP that currently doesn't work, and any variants of the JSP code you've tried that also hasn't worked.

No one have any idea how to access session variable in jsp in this kind of

Re: [S2] Testing if session variable is present
Posted by Milan Milanovic <mi...@yahoo.com>.
So, scenario is like this:
MyFirstAction.method1 [put session variable] -> show first.jsp -> user click
on link in first.jsp page -> show second.jsp -> user click on link in
second.jsp -> MySecondAction.someMethod is called -> show third.jsp where
this session test should be done.
I hope this helps.

Hi,
just to note, I treid with this too: <s:if test="#session.your_variable !=
null"> and it doesn't work.
I put my session variable in one action class, and then redirect to another
page which is connected to another action class. When that second class
method is runned, and resulting jsp is shown in that page I test this. My
both classes implements sessionAware.

Well, this : <s:if test="%{#session.your_variable != null}"> doesn't work,
event though my class implements sessionAware and I put my your_variable in
session before displaying this jsp page.
What can I do ?

I have one more question, not directly connected with this one. How can I ask
user with popup windows if he want to proceed when he click to some link,
without using Ajax and div tags ?

Hummm.. Struts 1 or 2?
This code is to S2.

I didnt test it, so im not sure about the code.
But try it, and tell us.
