Subject: Problem with result returning from interceptor
Hi,
In my application actions are distributed into several namespaces using
Conventions plugin.
When a request come for an action in a namespace (other than default one,
say, myapp/admin/action-name), and when there is no user session found, I m
returning 'login', which is configured as global-result in the default
namespace. But I m getting exception saying 'No result found with name...'.
Result config:
global-results result name=login type=redirectActionlogin/result
/global-results
Intercept() of interceptor:
public String intercept(ActionInvocation invocation) throws Exception {
MapString, Object session =
invocation.getInvocationContext().getSession();
User user = (User) session.get(Constants.USER_HANDLE);
if(user == null) {
return login;
}else{
invocation.invoke();
}
}
Action is in other namespace (package) and so jsp. But the result is
configured in default namespace, as login result should be accessible from
any namespace.
I m not getting what is the mistake I m doing. Is there any this kind of
problem with conventions plugin?
Some one please help.

RE: Need to disable session interceptor
I googled this and the struts2 performance tuning page says this Struts 2 does not create sessions unless asked to (for example, by having the createSession interceptor in your interceptor stack). Note that when you use SiteMesh however, a session will always be created I am never creating the session in my code directly and AFAIK I am not using SiteMesh (I don't even know what exactly is this). I have written code using JSP/Servlet and my knowledge says that unless the session is created explicitly it wont be created. Is there any interceptor in the defaultStack which creates it? (is the createSession part or defaultStack?) or I am doing something wrong. I opened some pages on my application and found there was one session created for my browser and others for other clients, So I guess this has nothing to do with JMeter. Sessions are being created for every client. I am trying to find out why is the session created when I did not create the session in my code. -- Rajeev -Original Message- From: Martin Gainty mgai...@hotmail.com Reply-to: Struts Users Mailing List user@struts.apache.org To: Struts Users Mailing List user@struts.apache.org Subject: RE: Need to disable session interceptor Date: Tue, 1 Sep 2009 09:23:58 -0400 Nils- doc suggests implementing a HttpCookieManager to handle the session any suggestions on which HttpCookieManager to implement and possible configurations?

Re: Need to disable session interceptor
When I upgraded from 2.0.x to 2.1.7 I found that the i18n interceptor now always creates a session too. The way I normally track down rogue session creations is to debug tomcat in Eclipse and add breakpoints to the javax.servlet.http.HttpServletRequest.getSession() and javax.servlet.http.HttpServletRequest.getSession(boolean) methods. That way you will find out exactly what the culprit is. Peter. 2009/9/1 musom...@aol.com: JSP create sessions by default. It is servlets that don't create a session unless you call getSession().

[SOLVED]: Need to disable session interceptor
I did not have %@ page session=false in the jsps which were included in other jsps using s:include. I put %@ page session=false in all the jsp pages and there are no more sessions created. Thank you guys for the quick help. Peter, I am using 2.1.6 and don't have sessions created any more. Are you sure i18n interceptor in 2.1.7 creates the session for every client? Should 2.1.6 and 2.1.7 have differences like this? it should be a minor release with no major changes.

I am not using session or cookies at all in my application right now. So I guess adding cookie listener doesn't make any sense to be added to JMeter test case. I shall use cookies later and shall add cookie listener to test my application. I don't want to store any data in web server so will not use sessions, rather shall store userid in cookie and fetch users data from memcache from cache machine based on the cookie. -- Rajeev Sharma Sr. Software Engineer Yahoo!

Problem with result returning from interceptor
Hi,
In my application actions are distributed into several namespaces using
Conventions plugin.
When a request come for an action in a namespace (other than default one,
say, myapp/admin/action-name), and when there is no user session found, I m
returning 'login', which is configured as global-result in the default
namespace. But I m getting exception saying 'No result found with name...'.
Result config:
global-results result name=login type=redirectActionlogin/result
/global-results
Intercept() of interceptor:
public String intercept(ActionInvocation invocation) throws Exception {
MapString, Object session =
invocation.getInvocationContext().getSession();
User user = (User) session.get(Constants.USER_HANDLE);
if(user == null) {
return login;
}else{
invocation.invoke();
}
}
Action is in other namespace (package) and so jsp. But the result is
configured in default namespace, as login result should be accessible from
any namespace.
I m not getting what is the mistake I m doing. Is there any this kind of
problem with conventions plugin?
Some one please help.

Re: Problem with result returning from interceptor
The conventions plugin reads a property called -
struts.convention.default.parent.package
Are you setting this property to the package that declares the global-result?

Check it out with the config-browser -- you should see on the results tab if

Struts - 2.1.6 - Prepare Interceptor
Hi Folks,
I have a problem as below:
1)
public abstract class AbstractBaseAction implements Preparable
{
public void prepare()
{
populateSomething();
}
}
2)
public class MyAction1 extends AbstractBaseAction
{
………
}
3)
public abstract class MyAction2 extends AbstractBaseAction implements
Preparable
{
public void prepare()
{
doSomething();
}
}
4)
public class MyAction3 extends MyAction2
{
………
}
I have a design as above.
The prepare() in AbstractBaseAction will do some common logic for MyAction1,
MyAction2 MyAction3.
The prepare() in MyAction2 will do some common logic only for MyAction3.
Only the prepare() in MyAction2 is being called for MyAction3. Since it’s
being overridden.
I want both the prepare() in AbstractBaseAction MyAction2 to be called one
after the other in the same order for MyAction3.
How to achieve this?
Please advice.
Thank you.

Kishan.G

Only the prepare() in MyAction2 is being called for MyAction3. Since it’s
being overridden.
I want both the prepare() in AbstractBaseAction MyAction2 to be called one
after the other in the same order for MyAction3.
How to achieve this?
Please advice.
Thank you.
Regards,
Kishan.G

Re: struts 2 portlet interceptor issue
Instead of writing interceptors I decided to go with the suggestion you made, which is use the raw session with the use of portlet:defineObjects/ but what I want to know is how can I access the jsp expression variables inside the s:property and s:if tags. We primarily use struts tags, because of this I thought of use s:set tag to assign the portlet application scope variable and use there after but it failed pls see the below failed attempt. portlet:defineObjects/ % UserSession userSession =(UserSession)renderRequest.getPortletSession().getAttribute(UserSessionForApplication,PortletSession.APPLICATION_SCOPE); String loginId= userSession.getLoginId(); % s:set name=studentId value='%=loginId%' / s:set name=studentId2 value=#attri.loginId / s:property value=studentId/ br s:property value=studentId2/ br none of the above printed the value, how to proceed on this Note: UserSession is one of our custom classes Nils-Helge Garli wrote: action name=testAction class=test.MyAction interceptor-ref name=sessionScopeHandler/interceptor-ref result/jsp/test/test.jsp/result /action With this configuration, your sessionScopeHandler will be the only interceptor running for this action.

struts 2 portlet interceptor issue
Hi,
I wrote a interceptor as follows but looks like variables/parameters in the
action class are not populated as part of the form submission. Which means
introspection does not seem to work it gives null values,
I only defined the interceptor not modified the default stack, pls advice
how to get the introspection also working,
my interceptor and struts.xml roughly looks as follows.
public class PortletApplicationScopeHandler extends AbstractInterceptor {
public String intercept(ActionInvocation invocation) throws Exception {
invocation.addPreResultListener(new PreResultListener(){
@SuppressWarnings(unchecked)
public void beforeResult(ActionInvocation invocation,
String resultCode)
{
//some logic here before it goes to the target
jsp
//
}
}
);
return invocation.invoke();
}
}
and in my struts.xml the interceptor looks as follows
package name=myStuff extends=struts-portlet-default
namespace=/myStuff
interceptors
interceptor name=sessionScopeHandler
class=test.interceptor.PortletApplicationScopeHandler /
/interceptors
action name=testAction class=test.MyAction
interceptor-ref
name=sessionScopeHandler/interceptor-ref
result/jsp/test/test.jsp/result
/action
...

Re: EJB Injection in Interceptor
Wow! Thanks for all this great feedback and ideas regards this problem.
I'm sorry I cannot add any useful prompts to help you develop a plugin
Wes as Spring and it's methods for injection are something I know
nothing about. I have to admit, injection is not something I fully
understand and anything I offered as a solution would likely be incorrect.
However, my only real requirement (currently) is to obtain local
references to both stateless and stateful session beans in Glassfish 2.1
from within Struts 2 action classes.
Looking at Haroons' examples, this would seem to be exactly the solution
I'm looking for and I will try and implement this.
Can I just ask two further small questions to Haroon?
Is the EJBInvokerServlet set to initialise at app startup via the
web.xml definition?
Does the EJBInvokerServlet approach work for stateful session bean
references as well as stateless?
Again, thank you for the time and effort everyone has gone through in
providing ideas and solutions to this problem. It is good to know that
this kind of expert help is available via the forum.
Many thanks, Robin

I use glassfish as my app server. To expose local EJB interfaces within
our entire application, I use an EJBInvokerServlet (uses the @EJB and
@EJBs annotations). The listing is as follows (took out package and import
statements and anonymized):
@EJBs(
value = {
@EJB(beanInterface = Local1.class, name = ejb/local1),
@EJB(beanInterface = Local2.class, name = ejb/local2),
}
)
/**
* Used to make local interfaces of listed EJBs available within the whole
* web application.
*/
public class EJBInvokerServlet extends HttpServlet {
}
The other way to inject beans is by specifying ejb-local-ref inside web.xml.
ejb-local-ref
ejb-ref-nameLocal1Bean/ejb-ref-name
ejb-ref-typeSession/ejb-ref-type
localLocal1/local
/ejb-local-ref
I prefer the Servlet approach as its simpler.
Wherever we need the EJBs to be automagically injected (the container does
its part because of EJBInvokerServlet), we then use the @Resource
annotation, e.g., to inject the Local1 interface, I would use:
@Resource(mappedName = ejb/local1)
private Local1 local1;
Hope that helps.
Haroon, it does and it doesn't. @EJB/@EJBs and @Resource aren't the
only DI annotations that are part of the EE specs. This is the problem
Robin has with the existing integration plugins. My understanding of
what he wants is that he wants to be able to use other annotations
(like @PersistenceContext) on fields in a struts action and have those
fields injected.
To turn it around and consider it compared to another similar
plugin... In the spring plugin, we delegate the class instantiation to
spring, then spring can decide what needs injected, etc. based on
spring configuration. What I'd like to do is apply the same concept to
EE. To do this in spring, there is an implementation of the
ObjectFactory that first tries to instantiate objects using spring,
and when that fails, it falls back on traditional xwork instantiation
(reflection-based). Once the object is created, the spring object
factory then checks to see if it can autowire the instance (based on
plugin configuration).
I'd like to try a similar approach with EE. The hard part is that I
don't know what API, or where to look for an API that instantiates EE
objects. Spring has 'applicationContext.getBean', is there something
similar for EE? Even if it's not as easy as Spring, I'm still willing
to wade through it for a bit since it seems like it would be useful to
at least a few users. The advantage to an object factory based EE
plugin is that I don't need to be aware of the annotations at all, I'd

Re: EJB Injection in Interceptor
You can either use Spring or implement your own EJB3 interceptor. Though I use my own EJB3 interceptor, I believe the best option is to go with Spring.

Re: EJB Injection in Interceptor
Sorry Robin, this is on my to-do list, but it's not something I'm working on right this second. One thing that is holding me up is the lack of knowledge of JEE. Is there a standard mechanism for creating instances of EJB-hydrated objects? For instance, if you annotated a field on a servlet with @PersistenceContext, the entity manager will be populated on the servlet. Obviously this works because the app server instantiates the servlet and the app server knows to do things like this. Is it part of the spec(s) that there is a way to instantiate objects, complete with dependencies injected? I know you can get objects from the JNDI context, but would that mean that objects retrieved need to be defined in JNDI? In the example with the servlet and EM, the servlet is defined in the web.xml, not the JNDI context... So, is there a place where I can read up on standard instantiation with EE DI? If it's not part of the standard, then, I still wouldn't mind building something specific to the app server that you are using (provided it is something I can get my hands on for free i.e. JBoss, OpenEJB). I started looking into this when this came up a few weeks ago, but I wasn't finding what I wanted so it got put off. If there is a way for me to call into the app server's own instantiation w/ DI facilities, writing this plugin would be a snap... -Wes On Thu, Jul 30, 2009 at 2:17 AM, Robin Manneringro...@mtndesigns.co.uk wrote: Just to clear up my actual question from the thread below as feedback has run dry unfortunately.

Hi Wes,
I don't know much of the details about the JEE spec, however, I can share
my implementation with you. The code is not in production yet, so caveat
emptor (it works for us, for now in development).
I use glassfish as my app server. To expose local EJB interfaces within
our entire application, I use an EJBInvokerServlet (uses the @EJB and
@EJBs annotations). The listing is as follows (took out package and import
statements and anonymized):
@EJBs(
value = {
@EJB(beanInterface = Local1.class, name = ejb/local1),
@EJB(beanInterface = Local2.class, name = ejb/local2),
}
)
/**
* Used to make local interfaces of listed EJBs available within the whole
* web application.
*/
public class EJBInvokerServlet extends HttpServlet {
}
The other way to inject beans is by specifying ejb-local-ref inside web.xml.
ejb-local-ref
ejb-ref-nameLocal1Bean/ejb-ref-name
ejb-ref-typeSession/ejb-ref-type

I started looking into this when this came up a few weeks ago, but I wasn't finding what I wanted so it got put off. If there is a way for me to call into the app server's own instantiation w/ DI facilities, writing this plugin would be a snap... -Wes On Thu, Jul 30, 2009 at 2:17 AM, Robin Manneringro...@mtndesigns.co.uk wrote: Just to clear up my actual question from the thread below as feedback has run dry unfortunately.

After creating another thread on the same subject at an earlier date, we discussed using the EJB plugin here: http://cwiki.apache.org/S2PLUGINS/ejb3-plugin.html However, having started to use this plugin so that I can reference stateless session beans, it seems that all EJB Session bean classes must be defined as @Remote rather than @Local in order for the injection to obtain the references correctly. Failure to specify them as remote throws a javax.naming.NameNotFoundException.

EJB Injection in Interceptor
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.

You should be able to just create a global result with the jsp you want. Ala: global-results result name=passwordChange/passwordChange.jsp/result /global-results Then have the interceptor return that string when needed. Any time it's true, the result will get hit and the user will get fowarded.

If it is not, I would then like to redirect the user to a login page with an appropriate error message. Is this an approriate use of interceptors?

This will configure *only* the sample interceptor.
If you specify *any* interceptors on a per-action basis you must configure
*all* interceptors. This can be done in several ways.
- specify all interceptors in the action's configuration (you can specify
interceptor stacks as well as single interceptors)
- creating a new stack including your custom interceptor and using that
stack in your action configuration
- same, but define the new stack and using it as the default stack

Re: Interceptor issue in Struts 2.1.6
All of the themes work with validation, it just depends on what you
are expecting out of validation. The validation workflow interceptors
will stop processing if validation fails and then indicate to the
framework that the input result should be rendered. Whether and how
you show the validation errors is a function of the view. The simple
theme does not display validation/action errors without the help of
tags such as s:fielderror and s:actionerror. The xhtml and css themes
will show the errors, but you do not have as much freedom, as far as
placement. The ajax theme is pretty much like xhtml.

Why all this WARN on interceptor (and how to eliminate?)
Hi all. I developed an application with struts2, tiles and EJB using jboss. In the log of jboss i've a lot of warning: 15:28:13,484 WARN [InterceptorRegistry] applicable interceptors is non-existent for public boolean session.MGMTBean.addCustomer(java.lang.String,java.lang.Stri ng,java.lang.String,java.lang.String,java.lang.String,double) 15:28:13,500 WARN [InterceptorRegistry] applicable interceptors is non-existent for public java.util.List session.MGMTBean.getAllOrders(entity.Customer) 15:28:13,515 WARN [InterceptorRegistry] applicable interceptors is non-existent for public java.util.List session.MGMTBean.getAllBought(int) 15:28:13,515 WARN [InterceptorRegistry] applicable interceptors is non-existent for public java.util.List session.MGMTBean.getAllItemByCategory(int) 15:28:13,531 WARN [InterceptorRegistry] applicable interceptors is non-existent for public entity.Customer session.MGMTBean.findCustomer(int) 15:28:13,593 WARN [InterceptorRegistry] applicable interceptors is non-existent for public java.util.List session.MGMTBean.findSimilarItem(entity.Item) 15:28:13,609 WARN [InterceptorRegistry] applicable interceptors is non-existent for public double session.MGMTBean.getTotalSpend(entity.Customer) 15:28:13,609 WARN [InterceptorRegistry] applicable interceptors is non-existent for public boolean session.MGMTBean.updateItem(int,java.lang.String,int, java.la ng.String,double,int,java.lang.String) where MGMTBean is my EJB.

but, when we check from the Apache console, the interceptor is not in the

at the end of the apache log, it show the interceptor is envoked.
Is there any additional configuration need to be setup to enable the

after we add validationWorkflowStack interceptor before the timer, then the

interceptor-ref name=validationWorkflowStack/

if we use the above in the action it is printing the timer value like below

Interceptor - Conditional Redirect to alternate action
I need to put an interceptor after the cookie interceptor that will send the user to a preference page if a preference cookie is missing rather than let the desired action fire--like a guard condition. If I was using a Filter I would just do a redirect. Eventually I will also add a Flash shared object as a back-up to the cookie, so I'll need to put a Flash shared object interceptor in the stack too. The redirector interceptor would check the cookie and flash token values put set by the previous interceptors in the stack. If both are missing, then a different action needs to fire. Where can I find an example of an interceptor that conditionally redirects the user to an alternate action? I'm having trouble picturing how the plumbing would work and I think an example of this kind would be a big help.

Re: Interceptor - Conditional Redirect to alternate action
Could you use a global-result? http://struts.apache.org/2.x/docs/result-configuration.html#ResultConfiguration-GlobalResults I would just think up a unique name for the set of conditions that should cause the redirect. Then, configure that string as a global-result and write your interceptor to do the check and return the string if the conditions are met and action.invoke otherwise. -Wes On Mon, Jun 8, 2009 at 10:09 AM, Mitchell, Stevensteven.mitch...@umb.com wrote: I need to put an interceptor after the cookie interceptor that will send the user to a preference page if a preference cookie is missing rather than let the desired action fire--like a guard condition.

RE: Interceptor - Conditional Redirect to alternate action
Oh, wow, that's incredibly simple. I was making it too complicated in my mind, thinking I needed to tell the ActionInvocation class not to allow the original action to fire. I see now that the answer was right there in the API [Interceptor.intercept()] - Allows the Interceptor to... short-circuit the processing and just return a String return code. -Original Message- From: Wes Wannemacher [mailto:w...@wantii.com] Sent: Monday, June 08, 2009 9:14 AM To: Struts Users Mailing List Subject: Re: Interceptor - Conditional Redirect to alternate action Could you use a global-result? http://struts.apache.org/2.x/docs/result-configuration.html#ResultConfiguration-GlobalResults I would just think up a unique name for the set of conditions that should cause the redirect.

Interceptor (Thread Safety)
If two copies of the same action is run at the same time parallelly (by ajax,
iframe, etc.) in the same session, possibly with different parameters, do
these actions call the same instance of an interceptor's intercept() method?
If this is the case, how to avoid problems that can arise?
For example,
there is an intercept method like
public String intercept(ActionInvocation actionInvocation) throws Exception
{
.Do some pre work
String result = actionInvocation.invoke();
.Do some after work
return result;
}
when the first copy of action is run, it does the pre work, then invoke() is
called, at this time action2 is run so it runs pre work, calls it's invoke()
then while doing after work, first action returns from invoke() thus
changing the value of result variable. So the result is now first action's
result and both actions return to the result from the first action, right?
is defining the intercept method as synchronized a solution?
thanks for the help.

String result = actionInvocation.invoke() ;
This is thread-safe, another thread will invoke the intercept method,
but the result string is scoped.
I think you might be misunderstanding how threading works. If your
pre-work and post-work only deal with variables locally scoped within
the method, then I don't think there is a problem. Here is an example
of a problem -
public class MyInterceptor extends whatever {
public String classScopedResultString;
public String intercept(ActionInvocation actionInvocation) throws Exception
{
classScopedResultString = gettingReadyToInvoke;
classScopedResultString = actionInvocation.invoke();
classScopedResultString = justGotDoneInvoking;
return classScopedResultString;
}
}

Re: How to setup Interceptor when using struts2.1.6 rest plugin with convention
xnpeng,
I think you are missing the point, packages have interceptor and
interceptor stack definitions. Actions live inside of packages. What
you need to do is move your conventions actions into your package. The
interceptor ref annotation will point to the stacks you want, but it
does no good if those interceptors are not defined in the package
where those actions live. To have your actions use your package,
change the configuration from -
constant name=struts.convention.default.parent.package value=rest-default/
to -
constant name=struts.convention.default.parent.package value=admin/
Then, conventions will put the actions in your package. Once this is
done, since you have a default-interceptor-ref in your package, the
interceptor ref annotations will no longer even be necessary.

Struts2 Interceptor
Hi all, can an interceptor call an arbitraty action different from the action requested by the client? Suppose i've the interceptor interceptor-router placed in the stack and the client call MyAction.action, when the interceptor intercept the call is possible to 'redirect' the call to MyDifferentAction.action from the interceptor? I've seen that there is action chaining but this require to know at build time the name of the actions i want to redirect to, but i know the name only at runtime and I hope i was clear :) sorry for my english. -- Stefano Corallo
Re: Struts2 Interceptor
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.

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 cant set it to the value/variable from jsps 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) Ill 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?

Re: Struts2 Interceptor
Hi Criss, thanks for your reply. I know the global result, but is unusefull for this purpose.

RE: Struts2 Interceptor
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.

RE: Struts2 Interceptor
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?

Interceptor Trouble
So, I've edited the struts.xml appropriately and I've created an
Interceptor that implements the interceptor interface. Init() is
called on startup but I can't get it to call intercept() to save my
life. My objective is to create an interceptor that checks to see if a
session variable is set and if not then take some action (either set
it or send the user to a page that sets it).
Here is the interceptor:
public class UidInterceptor implements Interceptor {
private static final Logger LOG = LoggerFactory.getLogger(sigacts);
public void destroy() {
LOG.debug(jim May 27, 2009 : destroy called);
}
public void init() {
LOG.debug(jim May 27, 2009 : init called );
}
public String intercept(ActionInvocation invocation) throws Exception {
LOG.debug(jim May 27, 2009 : intercept called);
return invocation.invoke();
}
}
Here is the relevant portion of the xml:
package name=xxx extends=struts-default
interceptors
interceptor name=UidIntercept
class=com.eds.xxx.web.admin.UidInterceptor/
interceptor-stack name=CustomStack
interceptor-ref name=paramsPrepareParamsStack/
interceptor-ref name=UidIntercept/
/interceptor-stack
/interceptors
default-interceptor-ref name=CustomStack/
/package
Clues anyone? I can see the init() being called in the logs but I
never see intercept.

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.

Re: Struts2 Interceptor
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.

Re: Struts2 Interceptor
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.

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

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.

Hi all,
can an interceptor call an arbitraty action different from the action
requested by the client?
Suppose i've the interceptor interceptor-router placed in the stack
and
the client call MyAction.action, when the interceptor intercept the
call
is
possible to 'redirect' the call to MyDifferentAction.action from the
interceptor?
I've seen that there is action chaining but this require to know at
build
time the name of the actions i want to redirect to, but i know the name
only
at runtime and
I hope i was clear :) sorry for my english.

RE: Struts2 Interceptor
hello dale-
in my xwork discoveries i came upon the ShortCircuitableValidator defined as
/** Copyright (c) 2002-2006 by OpenSymphony All rights reserved.*/
package com.opensymphony.xwork.validator;
/**
* This interface should be implemented by validators that can short-circuit
the validator queue that it is in @author Mark Woon
*/
public interface ShortCircuitableValidator {
/*** Sets whether this field validator should short circuit the validator
queue
* it's in if validation fails
* @param shortcircuit true if this field validator should short circuit on
* failure, false otherwise
*/
public void setShortCircuit(boolean shortcircuit);
/*** Gets whether this field validator should short circuit the validator
queue
* it's in if validation fails.
* @return true if this field validator should short circuit on failure,
* false otherwise*/
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 ?

i think that this is the only one solution. Thanks guys for your reply.
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)).
