Re: struts2 interceptor session timeout with ajax

[Lukasz Lenart]

I think you must use `onSuccessTopics` instead of `onErrorTopics` -
returning 403 doesn't mean an error

It won't work that way, when using Ajax you must use Ajax to redirect
to a login page. You can use something like this

http://cypressnorth.com/programming/global-ajax-error-handling-with-jquery/

so your interceptor must return 403 status code (it can return also an
url to login page to redirect to) and you must handle redirect on
client side

Re: struts2 interceptor session timeout with ajax

[Lukasz Lenart]

It won't work that way, when using Ajax you must use Ajax to redirect
to a login page. You can use something like this

http://cypressnorth.com/programming/global-ajax-error-handling-with-jquery/

so your interceptor must return 403 status code (it can return also an
url to login page to redirect to) and you must handle redirect on
client side

Re: Struts2 Interceptor

[Chris Pratt]

Sort of.  The way that I've achieved something similar to what you seem to
be asking is to define a bunch of Global Results in struts.xml that define
common actions that the interceptors may need to invoke (like reset-password
or invalid-input), then instead of chaining to the action in the
interceptor, just return the name of the global result and you've
effectively called that action.

RE: Struts2 Interceptor

[Qunhuan Mei]

Hello David and Chris,

Thank you two very much indeed for your help. 

I have tried s:set tag with different scope and seems I can set a
parameter to any value I want, but I can’t set it to the value/variable from
jsp’s java code block, so I suppose s:set may not be applicable to my
requirement. (or I must done something wrong somewhere!? Sorry I might not
have presented the use case clearly in the first place)

I’ll check the JSTL approach later – I suppose I should use its set tag
(to a page scoped attribte?).

Cheers,

Qunhuan

Hi,
Sorry for my ignorance but could some one tell me how to access java code
block's variable in jsp page. See the sample code below (say, from test.jsp)

...
%
boolean goAhead = true;
int counter = 0;
...
%
s:if test=goAhead
... !-- go a head and do something --
/s:if 
s:if test=counter0
... !-- go a head and do something --
/s:if 
...

The reference of goAhead and counter within Struts' if tag is wrong. What
should be the correct way to reference variable from java code block in this
scenario?

Many thanks in advance,

Qunhuan

Re: Struts2 Interceptor

Hi Criss,
thanks for your reply.

I know the global result, but is unusefull for this purpose. The problem is
that the actions that i want to call is knew at runtime cause the
interceptor at init time scan classes with certain annotations and i want to
forward to those actions so i can't put the result in struts.xml because i
can't know what action to call.

So my question is: the only way for an action to redirect to another action
is via redirect-action-result ? like described in:
http://struts.apache.org/2.x/docs/redirect-action-result.html
Maybe putting in the annotation the information to call the action i want

RE: Struts2 Interceptor

[Steve]

Hi Stefano,

This looks like an awkward design as you would go through half the
interceptor stack expecting to call one action, and half the stack expecting
to call a second action.

As an alternative could you do something like the following:-

Create class (or Interface) ReceivingAction with sub classes as the
actions you want to assign dynamically.

Create a true action class ForwardingAction with a property ReceivingAction.

The interceptor can now dynamically create the class required (derived from
/ implementing ReceivingAction) and set it on the current action
(ForwardingAction). It could also place the ReceivingAction instance on the
ValueStack.

The main action methods you are interested in (e.g. execute) could simply
forward to the ReceivingAction instance. You will need to be careful about
interceptor order if you want to do things like set your parameter values on
your ReceivingAction.

I haven't implemented this myself, although I have implemented all the
techniques I have described. I'm fairly confident that this will achieve
what you want.

Cheers,

Steve

RE: Struts2 Interceptor

[Martin Gainty]

you might possibly be breaking the one action class design of Struts

is there anything in the 2nd Action class which will not be accomodated by the 
first class?

right now its simple to look at the interceptor stack and determine which class 
is being called in what order..although technically possible to create any 
other class (Spring accomplishes this DI functionality thru Spring configured 
Factories) you would need a reason to justify a change in flow:

Specifically:
1a)Which updated/new attributes would the new Action class contain?
1b)Can we not accomodate the new Action attributes in the original Action Class?

2a)Which updated/new methods would the new Action class contain?
2b)Can we not accomodate these new Action methods in the original Action Class?

3a)Which context (element and attribute) params would be introduced by the new 
class?
3b)Can we not accomodate these new Context Params in the original Action 
Context?

What happens when this new class abends..how do you debug?

(my concern is obfuscation of flow or process can lead to confusion in 
implementation)

What say ye Musachy?

If you make the global result shortCircuitRedirect redirect to 
%{shortCircuitRedirectUrl}, add that member and getter to your 
BaseAction class, and have your interceptor both set the Url on the 
action, then return the global result name, you'll be able to do what 
you ask.

 If you make the global result shortCircuitRedirect redirect to
 %{shortCircuitRedirectUrl}, add that member and getter to your BaseAction
 class, and have your interceptor both set the Url on the action, then return
 the global result name, you'll be able to do what you ask.

If you don't have a base class for all of your actions, you might be 
able in the interceptor to get ahold of the ognl valueStack and set the 
value directly, then refer to #shortCircuitRedirectUrl (in the ognl 
dictionary rather than an attribute on action (top of ValueStack)).

Yes, you can, though I don't really thing it's the right way to go.
Basically you use the body content of the s:set tag to set the variable to
the value of a scriplet expression like so:

s:set value=fred%= myVar%/s:set

Again, there are much better ways of coding modern web applications that
resorting to scriplets and I would certainly take the time to eradicate all
scriplets from your code as soon as you can, you will be happy you did.

 Hello David and Chris,

 Thank you two very much indeed for your help.

 I have tried s:set tag with different scope and seems I can set a
 parameter to any value I want, but I can’t set it to the value/variable
 from
 jsp’s java code block, so I suppose s:set may not be applicable to my
 requirement. (or I must done something wrong somewhere!? Sorry I might not
 have presented the use case clearly in the first place)

 I’ll check the JSTL approach later – I suppose I should use its set tag
 (to a page scoped attribte?).

 Cheers,

 Hi,
 Sorry for my ignorance but could some one tell me how to access java code
 block's variable in jsp page. See the sample code below (say, from
 test.jsp)

 ...
 %
boolean goAhead = true;
int counter = 0;
...
 %
s:if test=goAhead
... !-- go a head and do something --
/s:if
s:if test=counter0
... !-- go a head and do something --
/s:if
 ...

 The reference of goAhead and counter within Struts' if tag is wrong. What
 should be the correct way to reference variable from java code block in
 this
 scenario?

 Many thanks in advance,

 Qunhuan

Re: Struts2 Interceptor

[Chris Pratt]

You can still use the Global Result, just set the global results value to an
OGNL expression.  This limits the places you can use the interceptor to
actions that can fill the OGNL expression, but you could handle that with a
common base class if you really want to go down this path.  I don't think
you really want to just call another Action (which is totally doable, but it
won't have any of it's data since it's interceptor stack won't have been
run).  Basically what you want is a method on your common base class like:

method getNextAction () {
  return next;
}

And a global result like:

result name=gtfo type=redirect-action${nextAction}/result

I think you would be better off sticking to the tried and true patterns that
the Struts team has designed the system to work with, but if you must, this
should work.

 So my question is: the only way for an action to redirect to another action

 Maybe putting in the annotation the information to call the action i want

hello dale-

/**

public void setShortCircuit(boolean shortcircuit);

/*** Gets whether this field validator should short circuit the validator 
queue

 * @return true if this field validator should short circuit on failure,

public boolean isShortCircuit();
}

//action class not implements ShortCircuitableValidator
public class MyAction extends ActionSupport implements 
ShortCircuitableValidator 
{
OgnlValueStack vs = new OgnlValueStack();
String isBogus =(isShortCircuit()==true)?true:false;
try {
vs.setValue(shortCircuitRedirectUrl, isBogus, 1);
}
 catch (OgnlException e) 
{
  log.debug(OgnlException happened here+e.getMessage());
 }
}

would this work for shortCircuitRedirectUrl ?

In an Action when I need the value stack I don't construct a new one but 
instead get it from the ActionContext:


ActionContext.getContext().getValueStack()


would this work for shortCircuitRedirectUrl ?


If you want only some actions to be able to be short circuitable and 
wanted to set that on a class by class basis, then this interface sounds 
like a reasonable way to do so.  I believe the OP wanted to be able to 
have his logic work for *any* action.  Adding to his base class would 
work for any action that implements that base class, but not for a 
simple action that uses the struts default action class, which is why I 
suggested adding to the ognl context rather than setting a property on 
the action on top of the stack.  I don't believe the OP was asking about 
 something related to validation, but how to force users to a certain 
page/form (Oh, we have something we want to force you to do before you 
do anything else).

I just want to second this... @Transactional rocks! I just mentioned in 
another thread that you can have your services wired into actions that are 
configured by Struts rather than the plugin. IMO, it's a good idea to have 
your transactions bounded to your service layer, this way you can keep Spring 
configuration (even if it is just the @Transactional annotation) out of your 
Struts objects.

I guess your problem is in the xml file.
You are using error result type. But by default if validation error
occurs, input string is being returned.
So please use input instead of error and check again.

Don't validation errors go to input? Like so:

 action name=UserTest_*  method={1}
 class=com.simple.validation.Test
 result name=error/pages/error.jsp/result
 result name=input/pages/welcome-input.jsp/result
 result name=success/pages/welcome.jsp/result
 interceptor-ref name=guest/
 /action

I put the annotations on the setters.

@RequiredStringValidator(type = ValidatorType.FIELD, message = You must
enter a password.)

@StringLengthFieldValidator(type = ValidatorType.SIMPLE, trim = true,
minLength = 6, maxLength = 100, fieldName = pwd, message = Password
must be at least 6 characters)

public void setPwd(String password) {
this.pwd = password;
}

 class=com.simple.validation.Test
 result name=error/pages/error.jsp/result
 result name=success/pages/welcome.jsp/result
 
 interceptor-ref name=guest/
 /action
 
 
 the guest interceptor is:
 interceptor-stack name=guest 
 interceptor-ref name=defaultStack/
 /interceptor-stack
 
 any idea?

Try annotating the getter rather than the setter.
