Placing interceptor in arbitrary position in the stack

[Shawn Griffith]

Hi,

let's say I have this default interceptor stack





















input,back,cancel,browse









input,back,cancel,browse



using annotations on an action class, can I place another interceptor between 
prepare and model driven? Or do I need to re-declare the entire stack with the 
additional interceptor?

Thanks

Yes, this can be problematic if you want to have prepare() and
validate() called on initial action execution. If that won't work, we
can implement some sort of skip mechanism, to allow skip processing
given interceptor as there should be any kind of dependency between
interceptors.

Thanks for the reply Lukasz.  I thought about doing something like that,
but this page
https://struts.apache.org/core-developers/execute-and-wait-interceptor.html
mentions the ExecuteAndWait interceptor must be at the end of the stack.  I

prepare() and validate() are called by different interceptors, which
means you must put your Exec interceptor before them in the
stack. I would use a custom stack for Exec actions with proper
order of interceptors. As I see you have a default stack which is
prepended to Exec interceptor and that's why those methods are
called.

When using the ExecuteAndWait interceptor, is it possible to avoid calling prepare / validate methods on reloads?

[Burton Rhodes]

Through a recent debugging session I realized that when refreshing a "wait"
page during an ExecuteAndWait process, it calls the action's prepare() and
validate() methods each time. For some reason I thought Struts
would immediately identify the "waiting" Action, and if it wasn't finished,
it would return a WAIT result with the running Action at the top of the
stack.  I now realize since the ExecuteAndWait filter is at the end of the
interceptor stack, it obviously doesn't send the WAIT result until all
interceptors have been executed.

That said, in some of my long running actions the prepare() method hits the
database for some rather resource heavy database queries. So if I have an
executeAndWait page showing the progress status (refreshing every 2 seconds
in my case), this seems incredibly inefficient.  Is there a way to avoid
this?  Am I setting up my Action flow incorrectly?

A sample of one of my Action setups in struts.xml:

 

/struts/contact/contactDelete_modal.jsp
/struts/common/error/error_modal.jsp
/struts/common/login/login_modal.jsp

Re: URI too long error when using ExecuteAndWait interceptor

I ended up replacing the  tag refresh method with javascript that
parses the "url" variable and recreates a  element on the fly to
submit via POST.

URI too long error when using ExecuteAndWait interceptor

[Burton Rhodes]

I have a page that submits a form via POST and uses the ExecuteAndWait
interceptor.  On the "wait" jsp I have:

"/>

However, the includeParams "all" is including all the POST form variables
(which there are many), and as a result, I am getting a "URI too long"
exception.  Is there an easy fix for this?  Can't believe I've never run

Sorry but not. You must redefine the interceptor and feel free to open
a ticket in JIRA to cover this case.
If overriding the interceptor you must just override the
"getLocaleHandler" method and implement your own "LocaleHandler".

i18n Interceptor cookie

[Rita Brito]

Hi,


I am defining an i18n interceptor with name="localeStorage">cookie so that a cookie with the user's 
selected language is stored.


Everything is working fine if when I navigate in my domain (eg: 
my.domain.com/somepage.html).


However, when navigating to a subdomain (eg: 
my.domain.com/subdomain/somepage.html), a new cookie is created with 
path=/subdomain and the previous one (path=/) is not overriden, due to 
having different paths (despite having the same name).


My question is: is there a way of defining the cookie path other than 
having a custom i18n interceptor?



Kind regards and thanks in advance,

RE: default interceptor overriding parent package default interceptor

[Yasser Zamani]

Hi Steven,

We have similar config at showcase [1]. I putted a breakpoint at [2]. It works 
as expected i.e. for "index" action it hits break point as not a first 
interceptor but for "skill/save" action it hits it as the first interceptor.

Does issue persist with latest Struts 2.3.x version? Could you check with 
latest 2.5.x version? If in both the issue persists, then you may miss 
something in your app or checking method.

Regards.

default interceptor overriding parent package default interceptor

[Steven Yang]

Hi
I have the following setup of my struts2 xml.

in cus.xml

   
...no interceptors defined, using interceptors form defaultPackage

in cus-cus.xml

   
   
  
new interceptors
  
  
  


But all now all the Actions defined in cus.xml uses the newInterceptorStack
as the default interceptor.
I only want the Actions defined in cus-cus.xml to use the
newInterceptorStack as the default interceptor.

Using Struts 2.3.x

Please advice

Thanks

I found something at [1]. Following is it's copied answer:

"For the redirected request to come back and attach to the same session,
it needs a session ID, usually carried in a JSESSIONID (or another name)
cookie or in the URL as a parameter.

This cookie or URL parameter should be added by the servlet container
and you should not have to add it yourself.

If you do not see the cookie in your browser, and you are not attaching
the JSESSIONID to the URL, then it is creating a new session with each
request, and not attaching to the same session."

Re: [S2] ExecuteAndWait Interceptor // Only re-submit token parameters on refresh?

[Martin Gainty]

Hi Yassir

i could'nt find it in servlet-api spec?

https://tomcat.apache.org/tomcat-8.0-doc/servletapi/javax/servlet/http/HttpServletResponse.html

HttpServletResponse (Servlet 3.1 API Documentation 
...<https://tomcat.apache.org/tomcat-8.0-doc/servletapi/javax/servlet/http/HttpServletResponse.html>
tomcat.apache.org
Extends the ServletResponse interface to provide HTTP-specific functionality in 
sending a response. For example, it has methods to access HTTP headers and 
cookies. The servlet container creates an HttpServletResponse object and passes 
it as an argument to the servlet's service methods (doGet, doPost, etc).

i did find sendLocalRedirect method in ATG Dynamo HttpServletResponse
https://docs.oracle.com/cd/E23095_01/Platform.93/ATGProgGuide/html/s0803httpservletresponse01.html
HttpServletResponse - 
Oracle<https://docs.oracle.com/cd/E23095_01/Platform.93/ATGProgGuide/html/s0803httpservletresponse01.html>
docs.oracle.com
Set Response Codes. The response code for a request is a numeric value that 
represents the status of the response. For example, 200 represents a successful 
response, 404 represents a file not found, and so on.




i didnt know struts2 supported ATG Dynamo sendLocalRedirect

No it didn't mean "with chain interceptor" that you have added. It meant
the action1.execute (i.e. the Struts user him/herself) can store data in
session and can then retrieve them inside action2.execute after
redirect. It didn't mean Strut's RedirectAction result does these itself
i.e. access, read and pass all session data.

As mentioned above, we didn't mean RedirectAction result access, read
and pass all session data. The Struts user him/herself should store them
in action1.execute then redirect then access and read them in
action2.execute.

No you're right that there is no session access but as mentioned above,
it's OK. There is no need to pass session data. They're always available
at server side.

As Struts uses action name for the key of the background process saved

Glad to hear :) thanks! I would like to add that you also can delete
ExecAndWait interceptor. Then just save posted data in db and
immediately send a thank you message to your user. Then check for and
send emails (e.g. each 10 minutes) e.g. using quartz jar.

Unfortunately, I couldn't find a simple way :(

However, as a workaround, instead, in your email form jsp, could you put
the email body field as a POST param and the rest short fields which
need validation as GET params (i.e. in a query string inside action url
using s:url)? Because then you can use "/> which only counts GET
params i.e. only query string which doesn't include email body but
includes other validation needed fields.

But if I were you, I prefer to use two actions for such requirement.
action1 which doesn't have ExecAndWait interceptor but has others like
validation, gets form data and stores them as a single object inside
session with a unique key every-time i.e. a GUID. Then action1 redirects
to action2 and also passes that key to action2. action2 behaves like a
mail sender and only has ExecAndWait interceptor. action2 gets then
deletes data from session by that key and the rest is same as your
current single action :)

Re: [S2] ExecuteAndWait Interceptor // Only re-submit token parameters on refresh?

Yes. I believe this is the case. Let me see if I can track down an example
that breaks. Right now I just have reports of this happening but I haven’t
been able to reproduce on my end yet.

Also, How would I include everything except the email body field with the
s:url tag?

Could you try including all except the email body field? I guess this
issue happens because the email body usually is too long to being
included inside url query string. To confirm, could you increase refresh
timeout to have time to right-click on your browser page then click view
source? I'm interested what is generated by "/> there when there is a

Thanks in advance!

[S2] ExecuteAndWait Interceptor // Only re-submit token parameters on refresh?

[Burton Rhodes]

I have been getting "Bad Request" or "URL too long" errors on occasion for
an email form that uses the execute and wait interceptor.  I am using the
 to resubmit the form per the documentation.

"/>

However, the original form submits via POST and the meta tag uses GET which
I believe is the source of the issue.  I've tried the code below thinking
that I could omit all the parameters except the token, but this doesn't
seem to do the trick.  Struts wants the entire form (again) - without all
the parameters the validate methods fail for the action class.



"/>

Any ideas on how to implement execute and wait correctly without submitting
the entire form via GET parameters each time a refresh that happens?

Thanks!

RE: Conversion Error Interceptor prevent errors for empty values

[Paul Zepernick]

Yasser,

Thanks for pointing me to the right class.  After debugging, I found the 
problem was in my template and it was including the option body in the value 
when trying to set it to empty.  There is no issue with the Interceptor and it 
is working as documented.  Thanks for your help.

No you should check
`org.apache.struts2.interceptor.StrutsConversionErrorInterceptor`
(prefixed with `Struts`) instead. Could you put a break point on it's 
`shouldAddError` method and see what happens when you post 
auditForm.incorrectAuditReason.id?

ServletConfigInterceptor calls setSession but only on action, not on

 if (action instanceof SessionAware) {
 ((SessionAware) action).setSession(context.getSession());
 }

I think you can rewrite your interceptor as below instead (like 
ServletConfigInterceptor):

SessionMap<String, Object> session;

@Override
public String intercept(ActionInvocation arg0) throws Exception
{
session = arg0.getInvocationContext().getSession();

You should be able to create a basic interceptors stack and use it in
your other stacks, so you can configure all the parameters in the

Setting interceptor param on package level

[Norbert Harrer]

Hi.

A question just out of curiosity. Is it possible to set an interceptor 
parameter on the package level.


For example I have a couple interceptor stacks more or less like this:






true
ERROR




I want the Parameters for the ExceptionMappingInterceptor to be present 
in all interceptor stacks:


true
ERROR

Is it possible to set them somewhere just once on a global or package level?

Thanks!

HttpParameters httpParameters = HttpParameters.create(parameters).build();
invocation.getInvocationContext().setParameters(htttpParameters);

this should work.

S2 String Trim Interceptor?

[Burton Rhodes]

Since the invocation.getInvocationContext().getParameters().toMap() method
is now deprecated, how would I refactor my String Trim interceptor to trim
incoming parameters?  The HttpParameters parameter objects are designed to
be "immutable".  Some posts online have suggested type converters, but
seems like this is the perfect use for an interceptor.

My trim interceptor code is below...

protected String doIntercept(ActionInvocation invocation) throws Exception {
Map<String, String[]> parameters =
invocation.getInvocationContext().getParameters().toMap();
for (String param : parameters.keySet()) {
if (isIncluded(param)) {
String[] values = parameters.get(param);
for (int i = 0; i < values.length; i++) {
values[i] = values[i].trim();
}
}
}

return invocation.invoke();
}

Thanks!

Well, doing it with reflection would mean to populate the action as ususal 
and logging it's values afterwards. IMO that should work. An issue could 
be that you don't log data which is present in JSON but not applied to 
actions.


Logging data from request body is general a hard issue for web 
applications, no matter what programming language or framework. A simple 
way to avoid the memory issue of my previous proposal would be to store 
data on disk (which introduces other issues of course).

Or if you use a reverse proxy like apache or nginx you could log data 
there.

Another option could be to check if your application server provides an 
option to log request data.

I would use a marking aware interface, the same as is done in Struts

Passing a parameter from an interceptor to an action

[Heikki Hyyrö]

Hi,

I would like to pass a parameter from an interceptor to an action, but 
am not sure what is a proper way to do it if I also want to ensure that 
a parameter with the same name cannot be injected into the action as a 
request parameter.


I have set the interceptor to add the parameter into the valuestack, but 
this approach does not seem to work if the parameter name is included 
either in the excludeParams-parameter of the params interceptor or as a 
blocked parameter of the parameter filter. Either of these last two 
seems to prevent the parameter from being accessible by the action. If 
the params interceptor and parameter filter apply to _all_ values in the 
value stack, and not only request parameters, then is there some other 
route that allows to pass a "private" parameter from an interceptor to 
an action?

So It is possible in my web app to post large amount of data...

I am trying to use the reflexion API to retrieve all getter of actions and then 
try to get one by one getters... 

I don't think if it's a better solution to do that.

Well, when your interceptor reads the inputsream it has to preserve data 
in memory in some way and your actions must read it from there.

You can try to copy the inputstream to a byte array first (by using 
ByteArrayOutputStream) and wrap request.getInputStream() with a 
ByteArrayInputStream pointing to same byte array. Of course that will 
cause issues if your users upload large amount of data.

You are right I have tried to use "request.getReader()" and after the json 
object was not available anymore.
How can I rewrite them ? Should I do the same like in JSONInterceptor ?

Re: What is the best way to get all JSON params in custom Interceptor to log them all in a custom logger ?

[Christoph Nenning]

Hi,

AFAIK that is defined in servlet spec. Only parameters with content-type "
application/x-www-form-urlencoded" are made available via getParameters(). 
The struts method you mentioned just forwards to according method of 
servlet api.

Your json data can only be read by consuming request inputstream. If you 
do so in your interceptor it is not available anymore to your actions (or 
struts json interceptor) so you must rewrite them, too.

Regards,
Christoph

What is the best way to get all JSON params in custom Interceptor to log them all in a custom logger ?

[Snowball RC]

Hi,

I am trying to implement a custom Interceptor to have a global custom 
"security" logger in my web app.

The target is to log all the datas sended to the server during update, save, 
delete etc... to have a custom logger for security reasons.

In case of GET and POST (query string param or form data without json object) : 
HttpParameters httpParameters = ActionContext.getContext().getParameters();
works fine.

But in case of json params in POST (request payload) the previous code doesn't 
works
when the params is serialize via : JSON.stringify(...)

code sample: 
jQuery.ajax({
type: 'POST', 
url: url, 
data: JSON.stringify(data),
dataType: 'json',
async: false ,
contentType: 'application/json; charset=utf-8',
success: function(){
 self.load();
},
error: function(data) {
 if (data.responseText) {
 var error = JSON.parse(data.responseText);
 }
}

My custom Interceptor is added at the end of my stack after the json 
interceptor like this :

application/json

I18N Interceptor Change

[Zoran Avtarovski]

HI Guys,

 

We have an old project which has been happily working for years. Recently we 
updated it to 2.5.x which was surprisingly easy.

 

One issue we did run into which was quite annoying was the I18N Interceptor now 
validates locales against the list of default available locales in this bit of 
code:

 

if (locale != null && 
!Arrays.asList(Locale.getAvailableLocales()).contains(locale)) {

    locale = Locale.getDefault();

}

 

The problem is our app is for refugees and not all the languages in in the 
available locales array. This must be relatively new as it worked in the old 
version 2.x ish.

 

As a work-around we over-rode the standard interceptor without the validation 
but I wanted to ask if the sore team could use a parameter to bi-pass the 
validation.

 

For example a tag in the struts.xml file:

 



  

 false

  



 

and then access it in the interceptor.

 

Z.

Passing Query String to Action through Interceptor

[Nick Broadhurst]

Hello,

I have an interceptor that is working fine except the query string is not
being passed on to the action from the interceptor.



iro/IroCaseFORM.jsp
 


URL: http:///EditIroCase.action?id=123

Action is an existing one that I am adding the interceptor to. Implementing
ParamAware to get ID from URL and that works fine. Tried a couple different
things, but can't seem to make it work. Used lots of interceptors, just
never needed to maintain a param across its execution.

Thanks,

Nick

RE: Token Interceptor between Struts1 and Sturts2

Thank you so much Chris.

With the TokenHelper class we resolved the issue.  Actually we do keep the s1

Hi,

you can invoke TokenHelper.setToken() from your struts1 code to generate it. In 
our apps that migrate from s1 to s2 we usually don't do things like that. We 
let one form be handled by one action. And migrate the wohle form/action to s2.

Re: struts2 interceptor session timeout with ajax

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

Have a  on a page.
After session timeout trying to click on another tab of tabbed panel should 
redirect the user to login page. 
 panel not firing the onErrorTopics. The javascript function is not 
getting called. The server is sending result 403. Please see below and guide me 
on how to fix this issue. I am seeing in fire bug that the 403 error is thrown 
but I am unable to catch it in jsp. Need help with the same.

struts.xml




/jsp/secondPanel.jsp 

403
User session expired  




jsp







$(document).ready(function() {  
  $.subscribe('loadError', function(event, status, data) {

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

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

If you really need access to Response you can get it via a static method 
in ServletActionContext.

S2: How to tell if a response has been committed from an interceptor?

[Greg Lindholm]

Inside an Interceptor I'm getting an exception

java.lang.IllegalStateException: Cannot create a session after the response
has been committed
I have access to the ActionInvocation as this is passed into doIntercept()
public String doIntercept(ActionInvocation invocation) throws Exception

My question is: from the ActionInvocation how do I find out if the response
has been committed?

Can I get the HttpServletResponse? So I can call response.isCommitted() ?

How?

Thanks,
Greg

Re: S2: How to tell if a response has been committed from an interceptor?

[Ken McWilliams]

Well you go down the chain create the result and then back up the chain.
So when going back up the response should already be committed.

see: https://struts.apache.org/docs/writing-interceptors.html

//modified code from above link to clarify
public String intercept(ActionInvocation invocation) throws Exception {
   //do stuff before response, going down the chain
   String result = invocation.invoke();
   //do stuff after response, going back up the chain, can't do what
you seem to be trying to do here...
   return result;
}

That aside, "Cannot create a session" isn't a good message because you
shouldn't be trying to create a session at all! It's part of the containers
responsibility to do that. You just ask for it. So the real cause of the
issue might be something else.

All,

Is it possible to get the ServletContext from an Interceptor's init()
method? I'd like to use it for some one-time initialization rather than
grabbing it during the interceptor's intercept() method and either
attempt one-time initialization or repeated-initialization.

How to add a global interceptor

[Jasper Rosenberg]

Hi,


 
I work on a project with hundreds of struts actions manywith their own custom 
interceptor stacks specified.  


 
We have recently internationalized the site, and so I had aneed to add an i18n 
interceptor to the top of every action stack.  It would have been impractical 
(and difficultto enforce for future actions) to add the new interceptor to 
every actiondefinition.


 
My solution was to override the ActionProxyFactory to returnour own 
ActionInvocation, which in turn always prepends the i18n interceptor tothe 
interceptor stack during initialization. 


 
I submitted a patch to make this extension simpler: 
https://issues.apache.org/jira/browse/WW-4553


 
However, it was suggested in the comments for this JIRA thatthere might be 
alternative methods to achieve my goal and to ask on this emaillist.  Thanks in 
advance for any advice!

Having actions with own interceptor stacks is quite special. Usually 
people have hundreds of actions but just a few interceptor stacks. And the 
few stacks are not created by copy-paste but by overriding configuration 
parameters and adding interceptors at the beginning or end of the stack.

Well, keeping so many stacks around surely is maintenance hell. And 
changing these stacks additonally in code does not make it better ;)



But as I said before: In your case I don't have a better idea.

Re: How to add a global interceptor

[Jasper Rosenberg]

Thanks for the feedback!
To be clear, we do have a number of interceptor stacks that are shared and we 
follow a similar pattern to what you describe where we add additional 
interceptors where needed before or after a common stack.  There are places 
that we might be able to reduce even that pattern by switching to action 
mapping parameters, I will definitely revisit that.  
The real problem is simply that there are so many actions at this point that to 
make sure we didn't miss any outlier custom stacks, we would have to review 
each one.  We would then have to add a struts configuration validation step to 
make sure no one introduced a new stack missing the required one (which I 
suppose wouldn't be that big a deal since we already do other configuration 
checks in development mode in a DispatcherListener).  Definitely food for 
thought...

Re: How to add a global interceptor

[Jasper Rosenberg]

No need for pity :)  It really hasn't really much maintenance overhead to this 
point.  Needing to do a change to all stacks is really the only case where I've 
seen it be problem.  Still, we have been pretty conservative in trying to keep 
our interceptor stacks thin.  It is probably worth the minor overhead of having 
more unused interceptors to allow more sharing of stacks.  Always more tech 
debt to work on!

  Lukasz -
 
  Thanks for all your help.  You got me on the right track and it appears
 the
  json Result was what was overriding and setting the content type.  As a
  result, I have overridden the JSONResult class to use the dynamic
  content-Type.

 You're welcome :-)

  /**
   * Custom json result type to set Content-Type response header
 dynamically
  to either 'application/json' or 'plain/text'
   * according to what the request header identifies in the Accept header
   *
   * (this is to fix browser wanting to download the json response on an
 ajax
  submit)
   *
   * @author Burton Rhodes
   *
   */
  public class JsonDynamicContentTypeResult extends JSONResult {
 
  private static final Logger LOG =
  LoggerFactory.getLogger(JsonDynamicContentTypeResult.class);
 
  @Override
  public void execute(ActionInvocation invocation) throws Exception {
 
  ActionContext actionContext = invocation.getInvocationContext();
  HttpServletRequest request = (HttpServletRequest)
  actionContext.get(StrutsStatics.HTTP_REQUEST);
  HttpServletResponse response = (HttpServletResponse)
  actionContext.get(StrutsStatics.HTTP_RESPONSE);
 
  // Set Content-Type according to what the request will accept
  if (request.getHeader(Accept)!=null 
  request.getHeader(Accept).toLowerCase().contains(application/json)) {
  this.setContentType(application/json);
  } else {
  // Default to text/plain
  this.setContentType(text/plain);
  }
 
  try {
  Object rootObject;
  rootObject = readRootObject(invocation);
  writeToResponse(response, createJSONString(request,
  rootObject), enableGzip(request));
  } catch (IOException exception) {
  LOG.error(exception.getMessage(), exception);
  throw exception;
  }
  }
 
 
  }

 Right now contentType isn't dynamically resolved, please register an
 issue and I'll add such option to JSONResult so you will be able to
 specify contentType via param/ tag, eg.

 result type=json
 param name=contentType${resolveContentType}/param
 /result

 and the action's resolvedContentType method will be called to obtain
 valid contentType


 Happy New Year :-)

Change Action Method In Interceptor

[R Veach]

Hi,

I know it is possible to limit struts to specific methods using the
MethodFilterInterceptor, and to change the execute method in the config or
form declaration using the method attribute.

Is it possible to have an interceptor change which method would be executed
in the action? I see I can get the method name using
invocation.getProxy().getMethod(), but I can't find any setter.

One reason I want to do this is to build submit and first time in logic
without defining it everywhere for every page and have an interceptor do
the work for me.
I would identify if it is first time or submit based on request to see if
it is GET or POST.
I could call the methods directly from the interceptor since I have the
action instance, but that would bypass the rest of the interceptor chain
and would require this interceptor to always be last in the list.

Here is an example of what I was planning:

//
if (isFirstTime(request)) {
if (action instanceof FirstTimeLogic) {
   invocation.getProxy().setMethod(executeFirstTimeInLogic);
}
} else {
if (action instanceof SubmitLogic) {
invocation.getProxy().setMethod(executeSubmitLogic);
}
}

return invocation.invoke();

The best option is to implement your own version of ActionProxyFactory
and ActionProxy - and used them instead of default one.

Re: Call a forward or a redirect inside an interceptor.

[ersinghlovepr...@gmail.com]

You can use dynamic url redirecting in this case :
This works like
in struts.xml you have to define result mapping.
result name=redirect type=redirect${url}/result

and in action you will define some getter setter like :
private String url;

public String getUrl() {
   return url;
}
 public void setUrl(String url) {
   this.url=url;
}

But in case of Interceptor getter setter is not working so You can just set
the value in stack like:
invocation.getStack().set(url, actionUrl);
and just return a redirect from interceptor instead of invocation.invoke()

BUT BE CAREFUL THIS WILL NOT LET ANY ACTION TO WORK IF YOU DOES NOT DEFINE
ANY CONDITION 
MAKE IF CONDITION TO ONLY THOSE ACTION WHICH YOU DON'T WANT TO EXECUTE AND
FOR REST MAKE INVOCATION.INVOKE() 
LIKE FOR EXAMPLE 

if(invocation.getProxy().getActionName().equals(DemoAction))
{
invocation.getStack().set(url, DemoAction2);
return redirect;
}
return invocation.invoke();
i have made this redirect only for action DemoAction , for rest i just
define invocation.invoke

For further clarification Please feel free to reply on this post 
enjoy

Adding custom interceptor in struts2 rest project

[Amol Ghotankar]

Hi All,

I was trying to get more deep in struts2 rest plugin.

To better understand things I have created a struts2-rest-sample on github
https://github.com/amolghotankar/struts2-rest-sample

Issues I see here are

1. If we add a customer interceptor then index action is not getting called.

2. We cannot update to struts2.3.20 - I guess this is known issue :(

3. How do we call http://localhost:8080/employee/111/projects.json
something like cascading actions here?

4. How can we return customer json response as for eg
http://localhost:8080/employee.json should return employeeId but
http://localhost:8080/employee/111.json should not return employeeId

There are more to come and I hope this github repo will help many other
like me.

Specially when these days we have angularjs being used heavily, people like
me would love to see struts2 more of a restful mvc which will sit only on
server side, but doing a little more for detached clients.

 s:textfield name=prop7 label=prop7 autocomplete=off/

 The SomeAction class has prop1 to prop5.
 The OtherAction class has prop6 and prop7.

 And I have the test.jsp with this:

 s:form action=someAction 
 s:textfield name=prop1 /
 s:textfield name=prop2 /
 s:textfield name=prop3 /
 s:textfield name=prop4 /
 s:textfield name=prop5 /
 s:submit /
 /s:form

 So my testing example is very simple: test.jsp calls someAction and
 populates prop1 to 5. Then it's chained into otherAction which populates
 prop6 and prop7 and finally we get the result into result.jsp.

 Whenever I chain someAction to otherAction, I can see all the values from
 prop1 to prop7 in the result.jsp page, even though I'm setting the
 chain.includes to be only prop1.
 In the other hand, whenever I redirectAction someAction to otherAction, I
 can only see the values from prop6 and prop7 in the result page, just as
 one expects (because whenever you redirect actions, the context from one
 action is not copied to the other, right?).

 Lukasz, please, do you have a Struts 2 project with a working example of
 the chaining includes/excludes? If anyone is interested, I think I can
 share my failing test project somewhere too.

 Masaki

Here you have a simple example

Re: How to setup includes/excludes in Chaining Interceptor

[Tenchi Masaki]

Hi Lukasz,

Thank you very much for your attention, it's really nice to have detailed
examples in the docs.
But unfortunately it's still not working for me. I've followed the example
exactly as the docs, but all the properties from SomeAction are being
copied. In the /result.jsp page I have this:

s:textfield name=prop1 label=prop1 autocomplete=off/
s:textfield name=prop2 label=prop2 autocomplete=off/
s:textfield name=prop3 label=prop3 autocomplete=off/
s:textfield name=prop4 label=prop4 autocomplete=off/
s:textfield name=prop5 label=prop5 autocomplete=off/
s:textfield name=prop6 label=prop6 autocomplete=off/
s:textfield name=prop7 label=prop7 autocomplete=off/

The SomeAction class has prop1 to prop5.
The OtherAction class has prop6 and prop7.

And I have the test.jsp with this:

s:form action=someAction 
s:textfield name=prop1 /
s:textfield name=prop2 /
s:textfield name=prop3 /
s:textfield name=prop4 /
s:textfield name=prop5 /
s:submit /
/s:form

So my testing example is very simple: test.jsp calls someAction and
populates prop1 to 5. Then it's chained into otherAction which populates
prop6 and prop7 and finally we get the result into result.jsp.

Whenever I chain someAction to otherAction, I can see all the values from
prop1 to prop7 in the result.jsp page, even though I'm setting the
chain.includes to be only prop1.
In the other hand, whenever I redirectAction someAction to otherAction, I
can only see the values from prop6 and prop7 in the result page, just as
one expects (because whenever you redirect actions, the context from one
action is not copied to the other, right?).

but now I noticed that all the parameters from SomeAction are being
copied. I was expecting that only prop1, prop2 and prop3 would be available
for the OtherAction.
I've tried setting only one prop and also using the expression
${'prop1','prop2','prop3'}.
It's all the same, all properties from SomeAction become available to the
OtherAction.
Is it supposed to be like this? Or am I doing something wrong?

How to setup includes/excludes in Chaining Interceptor

[Tenchi Masaki]

Hi,

I'm trying to configure a list of parameters to be passed into a chained
action, but I can't make it work. I've tried the following configuration in
my struts.xml:

action name=someAction class=com.examples.SomeAction
interceptor-ref name=basicStack/
result name=success type=chainotherAction/result
/action
action name=otherAction class=com.examples.OtherAction
interceptor-ref name=chain
param name=includesprop1,prop2,prop3/param
/interceptor-ref
interceptor-ref name=basicStack/
result name=successgood_result.ftl/result
/action

so I was expecting that prop1, prop2, prop3 would be copied into
otherAction, but none of the someAction properties are being copied.
I've tried the other way around setting the excludes instead, but didn't
work either.
What's the correct syntax to setup the includes/excludes params for the
Chaining interceptor? Thanks in advance!

Re: Rppe: What is the effect of Params Interceptor?

[Manoj . Sharma]

Dear Vineesh,

The params interceptor also known as parameters interceptor is used to set 
all parameters on the valuestack.It is found in the default stack 
bydefault. So you don't need to specify it explicitely. It gets all 
parameters by calling the getParameters() method of ActionContext and sets 
it on the valuestack by calling the setValue() method of ValueStack. 

Note: If you specify any interceptor for the action explicitely, default 
interceptors will not be available for the action class.

Please refer to these URLs: 
http://struts.apache.org/release/2.0.x/struts2-core/apidocs/com/opensymphony/xwork2/interceptor/ParametersInterceptor.html

dynamic interceptor insertion

Hi all,

I would like to dynamically insert an interceptor to a specific place
in existing stack.
Of course I also like the stacks referencing the one where I insert
the interceptor also take advantage of this configuration change.

Practicable to do this? I started to look on the side of
PackageProvider, but I can not find sufficiently complete
documentation allowing me to do this.

actionInvocation.getInvocationContext().getName()

Re: Find action method in interceptor ( One action class with lots of action methods in it)

[Antonios Gkogkakis]

Hi Alireza,

I believe you can have the method name of the executed action like this
actionInvocation.getProxy().getMethod()

 Please consider below action class:

   @Action(action1)
   public String action1(){

   }

   @Action(action2)
public String action2(){
 }

   @Action(action3)
   public String action3(){

   }
 }

 Is there any way in an inerceptor which I can find which method was really
 executed. I can find the class with

 myActionClass = invocation.getAction().getClass(); As I have many action
 methods in one class, how can I found which method was executed

S2 how to determine if a session exists from an Interceptor

[Greg Lindholm]

I have an Interceptor that wants to put something in the session after the
action has executed.

But if the session doesn't already exist I get an exception:

java.lang.IllegalStateException: Cannot create a session after the response
has been committed
How can I determine if the session already exists from within an
Interceptor?

 public String doIntercept(ActionInvocation invocation) throws Exception
 {
   String result = invocation.invoke();
   MapString, Object session =
invocation.getInvocationContext().getSession();
   session.put(key, value); // throws exception if session doesn't exist
   return result;
 }

Thanks
Greg

Hi Greg,
I seem to recall that this is not the best way to handle the session and
generally speaking, it always better to abstract as much as possible http's
details

I could be wrong, but It would be better if your action implements a
specific interface (SessionAware or HttpSessionAware)

Re: S2 how to determine if a session exists from an Interceptor

[Ken McWilliams]

The OP has abstracted away most of the details, he is working with
MapString, Object! The session is not generally struts2s responsibility
it, generally it is maintained by the web container. Tomcat/Glassfish, etc.
And generally you would consider it in such an environment to always exist.
What kind of container are you deploying your application in? I recall
there being an interceptor that will attempt to create a session for light
weight containers, however if struts needs to create such a session object
it is doubtful that the container will be able to use it in a meaningful
way.
