Re: The different output with Date whether the Http request have application/json

[Yasser Zamani]

Hi,

Thanks for reaching out!

Could you please try setting your desired value to Struts constant 
"struts.json.dateformat" and see if any change happens? Or try

Subject: The different output with Date whether the Http request have 
application/json

Hi all:

  I am new of use struts framework , and when I have a request with no
application/json to my app which use Struts framework having json
plugin , The Date Object return is something like
“2015-05-04T10:08:15+00:00” which is RFC 3339 format , Its fine .

  But when I have request with header have application/json , The Date
Object return is something like 1701522508943 . I believe which
represent the millionseconds since January 1, 1970, 00:00:00 GMT . But
how ?  I didn’t see any article mention it . And I didn’t get any tips
from source code . The DefaultJSONWriter seems not doing this ?

  Can someone tell me how and which java class turn the Date Object to
number and sent to front ?

Re: Struts 6.3 tags do not automatically evaluate the value field against the ognl stack

[Yasser Zamani]

Hi Nate,

Thanks for reaching out!

What I can't understand is how your app evaluates the value. Because I see the 
following in Struts UIBean.java since 2006:

// see if the value was specified as a parameter already
if (parameters.containsKey("value")) {
parameters.put("nameValue" , parameters.get("value"));
} else {

which I think means that it doesn't evaluate value if you've already set it. As 
far as I remember Struts evaluates name to calculate value if it's not already 
set.

Don't you have some specific magic in your app? Could you please see also 
Struts logs for any WARN message?

Regards,
Yasser

Subject: Struts 6.3 tags do not automatically evaluate the value field against 
the ognl stack

Greetings,

I am currently upgrading a Struts 2.5 project to Struts 6.3, and I ran into an 
issue with Struts 6.3 tags not evaluating the value against the ognl stack. I 
have reproduced this issue both with the radio map included in the struts2-core 
jar and with a custom radiomap.ftl, and also with an s:textfield instead of an 
s:radio. In both cases, the value attribute on the source page doesn't get 
resolved against the ognl stack, instead using the string literal entered in 
the value attribute.

I have about 140 s:radio components formatted like below, with "locked" being a 
Boolean field in the Action java controller:




In this case, none of the radios with a value set are setting their checked 
status based on the boolean value because parameters.nameValue doesn't get 
evaluated by ognl. If I remove the value attribute or make it an explicit ognl 
expression using %{}, it does resolve the attribute against the ognl stack and 
select the right item, but with the code above, the value got resolved against 
the ognl ValueStack in 2.5, but that doesn't happen in 6.3. Instead, it just 
sets nameValue to "locked" or whatever string literal "value" is set to.

I cannot find any mention of this breaking change in the migration guide, 
though I did find an issue dating back to 2007 mentioning a similar problem: 
https://issues.apache.org/jira/browse/WW-1907 which means that this either is a 
regression or it a deliberate design decision to no longer evaluate this 
property against the ognl stack.

Either way, I'd like to know whether this is an intentional change, and if so 
what the recommended way is to use a field on the ognl stack to configure the 
value of a field: should I add an explicit %{} evaluation symbol around the 
value attribute, or should I just leave out the value attribute entirely, 
instead relying solely on the name attribute set on the tag?

Re: Mirgrating to struts 2.5.30 from 2.3.37

[Yasser Zamani]

Hi Rohan,

Looks like something in logon.jsp is evaluated to null and you get 
NullPointerException. So I think firstly you need to debug jsp and see 
what's the root cause. If it's from Struts or not.

Yasser

Re: New warning message with V6.1.1 - SecurityMemberAccess...

You would have .disabled somewhere in your own app code ognl

Or put a break-point at [1] and see what ognl, how and why are trying to 
access UIBean.disabled non-public member!

The message is a result of the execution of this tag:
   

The variables are setup by the action class shown below, which forwards to the 
JSP containing the s:radio tag.

It seems to be working correctly, but the warning messages are puzzling. Does 
anyone know why the warnings are appearing?

Re: Not able to get Array of Objects values from one Action class to another

[Yasser Zamani]

Hi,

Thanks for reaching out!

I think it will work, but only for simple objects like strings and 
numbers. Are they simple object and it doesn't work? then please provide 
your jsp and action related portions. If not, then I think you likely 
should use session to store complex objects.


Regards.

Hi,


I'm not able to get the array of objects from one Action Class to another
in Struts 2.5.

In short, the flow goes like this:

Action Class A ---> JSP ---> Action Class B

I have the array of Objects in Action Class A and I'm able to get those
values in the JSP redirected from Action Class A.

On clicking a submit in the JSP, the execute() method of Action class B
gets executed and the Array of Objects in Action class B are always null.

I have getters and setters in both the Action Classes for the Array.



Usually, to get values from one Action class to another, using hidden
properties in the JSP works. But it does not work in the case of Array of
Objects.


I want to know how to get the Array of Object values in Action Class B.

Re: struts.ognl.expressionMaxLength

[Yasser Zamani]

Hi Ralph,

Thanks for using this feature!

Yes you're right. Struts uses OGNL not only for user's expressions, but 
also internally for its internal purposes :( and unfortunately, this 
feature cannot distinguish between them.


By the way, according to our security reports so far, 200 should be a 
good maximum [1]. That being said, we don't have a known attack vector 
less than 200 characters yet. 30 is too safe, however ;) Unfortunately, 
by now we don't and can't know what length Struts itself needs owing to 
complexity of different situations. I would say try 100, it should be 
enough. But as per [1], try to not use a value larger than 200.


Thanks again!

Regards,
Yasser.

After revising my code, I reduced the maximum OGNL expression length to 30, 
since the longest expression remaining in my code is 28 characters.

 

This, however, triggers another exception:

Evidently there are some automatically generated OGNL expressions with length 
longer than 30. What’s a reasonable minimum expression length that will 
accommodate these?

Thanks,
Ralph

I found the problem - I had neglected to include the leading spaces of the 
continuation line when calculating the expression length. They were converted 
to tabs in my editor, which made the expression shorter. Putting the expression 
on a single line eliminates the exception.

Original source:



Ok, I was suspecting so after inspecting the stack trace. Anyway I
would put such logic in the action or model, like this:

JSP:


Java class:
public class Participant {

  public boolean isNoSurveyResponse() {
return checklist <= 2 || surveyResponse == null;
  }
}

Re: Date Type Converter strange behavior

[Yasser Zamani]

Hi thanks for reaching out!

I don't remember and should check that your desired behavior used to work or 
not but as a quick answer I think you're looking for Class wide conversion [1] 
e.g. @TypeConversion(type = ConversionType.APPLICATION, property = 
"java.util.Date", DateConverter.class)?

Re: AliasInterceptor parameter mapping issue

[Yasser Zamani]

Hi Brian,

Sorry for inconvenience :( yes for me as well it looks like an 
unintentional bug introduced by [1].


Thanks a lot for writing to us! To followup its resolution would you 
mind create a new JIRA ticket?


Regards.

https://github.com/apache/struts/commit/787f2f96eb9f1bb3c8012ab42aa222ae6286a91a#diff-b7b7c87c1012088e79dcc5a7bd9e8127

Hello,

We are running into an issue with the AliasInterceptor after upgrading to
2.5.22 (from 2.3.35). The issue is that the fallback behavior to look in
HttpParameters for a value guarantees a value will always be set and that
Evaluated.isDefined() will subsequently always return true. The issue is
that HttpParameters.get() *always* returns a non-null value. If there isn't
an explicit value set, then it returns a Parameter.Empty. This cascades
back to AliasInterceptor, which results in the empty value *always* being
set on the stack.

As an example, let's say I have a parameter f with alias foo. If I set a
value for foo on the request, the behavior in AliasInterceptor will result
in an empty value being set for foo, thus overwriting the actual value
submitted.

Is this the designed behavior? Based on the structure of the code, it
appears to be a bug since there is unnecessary logic otherwise
(specifically, the call to value.isDefined() on line 179). Further, this is
different behavior from the older versions of Struts (pre-HttpParameters).

Instead, I would think that isDefined() should be checked on the
Parameter returned
from HttpParameters so that a non-null value is only set in the Evaluated if
the parameter is actually defined.

Does anyone have any thoughts or insight into this issue? I looked in JIRA
and couldn't find anything related to it. Does anyone know of any
workarounds (aside from creating a custom AliasInterceptor to fix the
behavior)?

Thanks!

Brian

RE: have plan to upgrade version of spring in struts 2 Spring plugin?

[Yasser Zamani]

Hi,

Thank you so much!

Yes we will upgrade Spring gradually during Struts 2.6.x releases - Struts 2.5 
is under maintenance mode only for security releases.

However, recent Struts 2.5.22 uses Spring 4.3.25.RELEASE [1]; doesn't it work 
for you?

RE: convention plugin Issue

[Yasser Zamani]

Hi,

I guess that the behavior of defining actions with same name and namespace is 
undefined. I think it's not an issue because Convention Plugin has no avenue to 
distinguish between them when you request http://localhost:8080/hello-world.

No. AFAIK User browser used JRE and your server JDK aren't connected, are 
independent. User browser talks with your tomcat via HTTP protocol and process 
your server text responses by its own local HTML, JavaScript, Flash, JRE and 
etc engines.

AFAIK they usually don't need whole system patches. They just need a latest 
browser download which usually is small. I'm not sure but maybe you can avoid 
using complex JavaScript and HTML components to work with old browsers but in 
general I think it's impossible to work with very old OS/browsers.

It's simple HTTP protocol  :)

No you don't. Using Apache HTTP server in front doesn't help working with old 
browsers.

I hope these help! But for further info Google is your friend. Simply search 
phrases like "develop for old browsers" and etc.

RE: Update views how to ?

[Yasser Zamani]

Hi Zahid,

Additionally, AFAIK...

If your users are a lot, then I think you have to wait for Struts 2.6 release 
where I've added support for Async actions. For an instance usage see my 
example at [1] (you can try it via running Struts 2.6 snapshot showcase - it's 
a simple chat room i.e. classic usage of server push).

Otherwise or anyway, for now, you can try if Struts ExecAndWait is able to 
handle your users.

Regards.

RE: How to pass parameters to s:component inside s:iterator?

[Yasser Zamani]

Hi Albert,

Could you try without the inner s:if tag? I remember that some tags don't work 
inside each other :(

Despite if it was the problem or not, I think it's more readable design to move 
iterator and if tags inside the component (items.jsp) itself, have you ever 
considered it?

Re: How to auto submit a jsp page after loading

[Yasser Zamani]

Hi Albert,

I think Dave is right -- if you wanted to test, then you would not do this.

What have you been using for test? If it tested UI also (e.g. Selenium),
it would have facilities to automate clicking on submit button [1]. If
you didn't want to test UI at all (e.g. JMeter), you would not try to
execute client side codes -- just call action via http, validate and
process result and repeat respectively.

Hope this helps!

Regards.

Re: JSON plugin: filter fields in a Map with Lists

[Yasser Zamani]

You're welcome :) Sorry I thought you don't need keys. If you needed
them, then following would work:

public Map> getResult() {
return result;
}

^result\.[^\[]+\[\d+\]\.interestingProperty$


Then only limitation of this one is that keys should not contain [
character because of [^\[]+ which I had to use instead of .* to avoid
including all of the model.

Kind Regards.

Re: JSON plugin: filter fields in a Map with Lists

[Yasser Zamani]

Hi Micael, thanks for your report!

You're right! I debugged Struts with your model, Map>. I realized with following sample initialization:

MyObject mo = new MyObject();
mo.setInterestingProperty("IP");
mo.setNotInterestingProperty("NIP");
ArrayList mol = new ArrayList();
mol.add(mo);
result = new HashMap<>();
result.put("first", mol);

Struts checks result.first[0].interestingProperty if it has any
includeProperties matches.

The map key can be any string i.e. .* Consequently you have to have
result\..*\[\d+\]\.interestingProperty but .* causes including all of
the model -- because Struts splits above into multiple regex: result,
result\..*, result\..*\[\d+\] and result\..*\[\d+\]\.interestingProperty
and checks input with them respectively. The second one passes all!

I just could find following workaround which you might like:

private Map> result;
public Collection> getResult() {
return result.values();
}

^result$,^result\[\d+\]\[\d+\]\.interestingProperty$


Hope this helps!

Best.

RE: Migrating the Migration Guide

[Yasser Zamani]

Hi,

Sorry I cannot recall why we should migrate -- Have INFRA compelled us and 
Confulence is going to be removed? Or just to beautify?

Anyway, I think we can use a Jekyll/Ruby custom tag component which at site 
build time, downloads that Confulence's page html as an anonymous user and 
includes it in output -- like what I've already done for some snippets.

ApacheCon Europe 2019: Join Struts Hackathon!

[Yasser Zamani]

Dear Struts Community (@user, @dev, @pmc),

There will be a hackathon space at ApacheCon Europe 2019 in Berlin
reserved for Struts. It will be available on 23rd/24th October from 1:00
PM for 2/4 hours.

We want to invite everybody to participate on the hackathon where we are
collaboratively researching, discussing and developing effective usage
of Asynchronous [1] using Struts. Then we are trying to add it into Struts.

That's our initial default topic, would you like to amend? If so,
collaborative development on project source code, improvements to
project documentation, and development of example apps or tools built
upon Struts are all encouraged.

Furthermore, it's a nice opportunity to get in touch with other users,
contributors and committers.

More details will be available leading up to the event, but here’s
generally what to expect:

- Dedicated space with chairs, power, wifi, snacks, and caffeine.
- Tables dedicated to Struts.
- ‘Getting Started’ discussions for new and aspiring committers
- (industrial) IoT Corner with industrial equipment to code against

Interested? Email user@struts.apache.org to amend topic or just to count
attendees :)

Thanks!
Apache Struts Team

P.S. Swag and stickers on RedBubble are also available [2]. Enjoy!

I also like to not see that value in Map but maybe it's required for
some reason - I didn't check. But you may use following workaround:

if (!hasFieldErrors() || !getFieldErrors().contains(myFieldName) {
// my extra customized validation logic for myFieldName
}

Me too! Could you please put a break-point at your app's [1] and see
what happens next for that field?

RE: Invalid Field Value when using Map

[Yasser Zamani]

Hi,

I think putting breakpoints at [1] and [2] and seeing if you reach there and 
what happens next can help proceeding this issue.

Thanks in advance!

Re: Invalid Field Value when using Map

[Yasser Zamani]

Oh interesting!

Have you seen [1]? e.g. conversion error interceptor should be present
in your interceptor stack. To debug, for example put a number field
which is not a map and see if conversion error appears - I think you
should also have fieldErrors tag in your jsp.

It seems your action also should be ValidationAware. Put a break-point
at [2] and see if your code reaches there and what happens next.

Hi Prasanth,

I'm surprised how you get non digit characters in your map while both key and 
value are not String!

Re: Upgrade from struts 2.3.37 to struts 2.5.20 issue.

[Yasser Zamani]

No I meant latest version of struts-jsf plugin jar. You have mentioned
"The previous problem had been solved." i.e. you already have
struts-core in classpath and already you have finished some migration;
So I told trying to also include latest version of struts-jsf plugin jar
and seeing if your app compile and run or if any exception.

Regards.

Re: Upgrade from struts 2.3.37 to struts 2.5.20 issue.

[Yasser Zamani]

Hi FANG,

I am not familiar with that plugin but as a simplest solution, does your
application compile when you simply put it's latest version jar in your
classpath? If so, does it run correctly? If not then I will look at that
plugin and think about any solution :) - and please also include the
first exception stack trace or error message if it doesn't compile or run.

Regards.

Hi Siva,

Use Struts "JSON Plugin" [1] which has json result for actions [2]. Regarding 
chains, use json result for last action in the chain e.g. for resetSubmit 
action in your example above.

RE: Issue : Binding Integer Array upon form submission

[Yasser Zamani]

Hi Muhammad,

I tested your sample exactly and works as expected here 
(setRfaAccessType(Integer[] rfaAccessType) called with ticked values).

The first thing you can do is enabling devMode and log level to warn and 
looking output for any relevant warnings. If not try debug level.

Thanks for using Struts.

RE: Mapping struts.xml actions to their full URL

[Yasser Zamani]

Hi there,

The whole Struts itself is a servlet/filter defined in web.xml and you cannot

Hi Deborah,

I tested the syntax and it works. If it doesn't work there then I guess
if reportId is String then try  else then
try . Also
try replacing || with && or != with == variations.

Thanks for using Struts!

What about http://localhost:8080/learning-0.0.1-SNAPSHOT/listUser or 
http://localhost:8080/listUser. I don't have experience with Jboss but in 
tomcat we can open /manager and see what's going with webapps. Does Jboss have 
similar thing? In general I think you should discover in which context path the 
app is deployed? Is it started at all?

Re: How to use s:iterator s:include s:param

[Yasser Zamani]

Hi Albert,

I found following at [1].

"Note: Any additional params supplied to the included page are not
accessible within the rendered page through the  tag since
no valuestack will be created. You can, however, access them in a
servlet via the HttpServletRequest object or from a JSP page via a
scriptlet.

How To access parameters

Parameters are passed as request parameters, so use the
${param.ParamName} notation to access them. Do not use the property tag
to access parameters in included files."

So it seems you can use ${param.itemList}.

Thanks for using Struts!

Regards.

No, AFAIK finally both are http parameters.

I expect ArrayList to work also e.g. for rowNumber=3, I expect delete={null, 
null, null, "Delete"} :( Could you please set devMode and increase log levels 
to WARN and check the output? What Struts version do you use?

Regards.

RE: Map backed form

[Yasser Zamani]

I think a file named yourActionClass-conversion.properties beside your action 
with following contents should help [1]:

Key_xxx=java.lang.Long
Element_xxx=java.lang.Double

(where xxx is the field name of the collection property in your action or 
object)

Re: How to import Struts Examples into Eclipse IDE inside a single project

[Yasser Zamani]

Hi Albert,

Please see if https://stackoverflow.com/a/38714946 helps. If not, you
have to ask Eclipse team or research further if it is even possible and
how. Unfortunately I don't have experience with any multi-module maven
project with Eclipse (it's not specific to Struts).

Regards.

RE: Struts2 Checkboxlist

[Yasser Zamani]

Ach! Sorry, you're right. For checkbox list it's MultiselectInterceptor class 
which handles this and here it works with following config:

List selectedLongs= new ArrayList<>();
public List getLongs(){
List longs= new ArrayList<>();
longs.add(0L);
longs.add(1L);
return longs;
}
public void setSelectedLongs(List selectedLongs){
this.selectedLongs = selectedLongs;
}
public List getSelectedLongs(){
return selectedLongs;
}




/WEB-INF/tags/ui/exampleSubmited.jsp
/WEB-INF/tags/ui/example.jsp



When I post an empty form, MultiselectInterceptor adds an empty string for 
selectedLongs http param, then Struts internal conversion converts it to an 
empty instance of List, then setSelectedLongs will be called here with it.

Regards.

RE: Struts2 Checkboxlist

[Yasser Zamani]

Hi Prasanth,

AFAIK this tag is like this:



It calls getBar method of your action or finds bar in value stack to find out 
what to display. Same for baz to find out which to be selected. Then it calls 
yourAction.setFoo to post selected items. i.e. it is up to you what you do with 
it in setFoo method. Normally you should clear baz and fill it with them again 
to update selected items.

Thanks for using Struts!

It seems firstly ${placeholder} is evaluated to empty by Struts then '' is

I guess '$'{placeholder} or $'{placeholder}' or '$''{placeholder}' should work

Yes I recently learnt it but I always logically had this assumption: When bean 
A needs bean B to be injected and B's type is `prototype`, then Struts internal 
injection cycle always re-inject a new instance of B into A regardless if A's 
type is `singleton` or `prototype`. So I missed this case :( and Ach, you're 
right, I now can retain my high concurrent test was on JSONResult not 
JSONInterceptor :(

RE: EmptyStackException after upgrading Struts 2.3 to 2.5

[Yasser Zamani]

Hi,

Yes you both are right. It looks like a race condition between stack.clear and 
stack.write [1]. But somehow it's odd. I was aware about this and defined them 
as prototype [2] so I except new instance on each request. I also can recall I 
tested them heavily on high concurrent load [3].

By the way, Eduardo, you also can workaround this issue for now by 
synchronizing access to custom.action via using java synchronized keyword 
inside your action method.

Thanks for using Struts!

Regards.

RE: S2.5.20 Illegal reflective access by ognl.OgnlRuntime

[Yasser Zamani]

Hi Lukasz,

Just FYI I personally feel it's not related to static accesses - It seems Java 
11 warns such accesses and next Java release won't allow such accesses anymore 
i.e. current ognl won't work on them anymore.

Regards.

Re: Java 11 support

[Yasser Zamani]

Hello and Thank you Sebastian!

Could you please continue with this workaround: downgrade OGNL to 3.1.18.

 ognl
 ognl
 3.1.18

and report if any further issue emerges? If so it's so great to fix them
as well for 2.5.21. If not, then, it's an another evidence to merge [1],
I think :)

Sincerely Yours,
Yasser.

Re: Java 11 support

Hi Sebastian, thanks again for your time to feed back! It's really a
great help.

Regarding the web app doesn't work, it always a good practice to enable
devMode and set log mode to warn or at next step to debug.

Kind Regards.

Yes I already got the issue. As I illustrated above, I think I already
done your proposed test scenario. As I illustrated above, I had compiled
Struts showcase app with JDK11 source and target but had compiled the
rest modules (including core and plugins and etc) with JDK7 source and
target. I even had verified this in struts-showcase.war via viewing
.class files raw first 8 bytes. This same struts-showcase.war with
current 2.5 branch logs same errors which Sebastian and Paul reported.
But this same struts-showcase.war with my proposed PR launches with no
error in output and convention-based actions of it works fine.

Regards.

I'm not sure if I get your point correctly but I didn't change `target` in [1].

If you meant the user's itself java 11 compiled classes structure, to double 
verify if it works, with [1]'s local branch with a few local changes into 
showcase app, I compiled showcase app into a war file with JDK11. Inside the 
war file, I verified that showcase classes are compiled with JDK11 and 
WEB-INF\lib\struts-convention-plugin.jar classes are compiled with JDK7 (via 
viewing their .class files first 8 bytes) i.e. similar to Sebastian case. I 
then deployed that war into tomcat starting with java 11. I saw it launched 
with no error and I saw it's bean-validation-example.action (a convention 
configured action) works fine.

Regards.

Fortunately it seems it isn't required. Locally all tests are passing here with 
all java versions (7,8,9,11) for [1].

Kind Regards.

"According to ASM7's source codes, it seems it uses passed api version only to 
check if it should throw an unsupported exception or not (i.e. doesn't have any 
effect on functionality and somehow is just a validation). So, as we upgrade to 
asm.version=7.0 for default then I think it's OK to upgrade Opcodes.ASM5 to 
Opcodes.ASM7 as well. It only breaks when user manually exclude ASM7 dependency 
with an older version which is not usually expected."

Hi Łukasz,

I would prefer to allow user to optionally override the default Opcodes.ASM5 
via a constant in struts.xml e.g. , Or more better, to think if it's possible to determine 
it at runtime via user's runtime context e.g. java version. Wdyt?

Hi Paul,

Thanks for your time!

Could you please check if any further issue persists with my solution posted in 
previous mail in list (beside the workaround for drop-in ASM7 dependency)? I 
think "This feature requires ASM7" will vanished with it but I'm not 
comprehensively sure if any further issue arises after. If so, it would be nice 
to fix them in 2.5.21 as well (beside asm.version=7.0).

Thanks in advance!

Kind Regards.

Hi Yasser,

sure! We are not in a hurry :-) but really looking forward to this release. I 
tried with the 2.5.18 yesterday.
But then I will await the 2.5.20 release with pleasure.

I know this sort of question sucks but will the release be ready this month 
already or will it take somewhat longer.

Kind regards,

Sebastian

production also.



Thanks for using Struts!

Now with JDK 11 it looks a bit more complex getting the Java 9 module

So the question is: how and when is it going to be possible to use

struts2 with Java 11?

RE: Context parameters not being ignored?

[Yasser Zamani]

Hi Micael, Happy New Year :)

With a glance on stack traces, I saw the second isn't an injection but is a 
copy-paste operation from prior action to next action by ChainingInterceptor. 
i.e. it seems you have a cyclic chain result or a chain result between two 
actions that both have fooService. Please consider some analysis on your chain 
results then I think you may find some trifles to fix.

Thanks for using Struts!

RE: How to display both selected key and value of s:select

[Yasser Zamani]

Hi Albert,

The simplest method can be something like this:

public class RegisterAction {
...
public Country getSelectedCountryObject() {
foreach (c in countryList) if(c.countryId==selectedCountry) return c;
}
...
}



Thanks for using Struts.

RE: [ask] How to pass multiple radio button in struts2

Hi,

As different values are setting into same viewAccess[0], I guess instead 
`private String viewAccess[][];` (array of array) would work.

RE: Context parameters not being ignored?

Hi Micael,

I think putting a breakpoint on OtherAction.setFooService and probing the full 
stack trace when the execution hits it for second time would help to reveal 
what and who's the villain of second injection :)

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.

RE: Ask - "Reloading all providers." everytime invoce action.

[Yasser Zamani]

Hi,

Sorry this is a bug in 2.5.18 which only occurs in development mode, so, the 
easiest workaround is to set struts.configuration.xml.reload to false.

This bug already has fixed [1] and will be released soon with 2.5.19.

RE: Apache Struts 2.3.x End-Of-Life (EOL) Announcement

[Yasser Zamani]

Hi Siva,

Yes you need to upgrade to latest released version and you have six months' 
time to do this. After that, Struts 2.3.x loses any support even security fixes!

Thanks for using Struts!

Re: Struts 2.5.x support above Java 8

[Yasser Zamani]

Hi Paul,

I'm pleased to announce it seems we were able to add both java 9 and 11 
supports into Struts 2.5.19. Could you please wait for its release and then 
tests the bits? It currently can pass all tests with all jdks (see [1]) but 
it's so great if you will be able to test it in production also.

Regards.

+1 I like testing section idea. FYI I have some clean nice interesting 
practices done in it such as:

* Integrating Spring, Struts, Hibernate and DBUnit to work properly together to 
test an application via extending them.
* Having an in-memory from-scratch database for each test to keep tests 
independent from environment.
* How to disable that database foreign keys in tests.
* How to initialize that database with data via XML files for each test.

[ANN] Apache Struts 2.3.36 GA

[Yasser Zamani]

The Apache Struts group is pleased to announce that Struts 2.3.36 is available 
as a "General Availability" release. The GA designation is our highest quality 
grade.

Apache Struts 2 is an elegant, extensible framework for creating 
enterprise-ready Java web applications. The framework is designed to streamline 
the full development cycle, from building, to deploying, to maintaining 
applications over time.

This release addresses one backward compatibility issue. Below is a full list 
of all changes:
- xml-validation fails since struts 2.5.17
- MD5 and SHA1 should no longer be provided on download pages

Internal Changes:
- XWorkList was moved into a com.opensymphony.xwork2.conversion.impl
package as com.opensymphony.xwork2.util package is excluded by the Internal 
Security Mechanism.

Please read the Version Notes to find more details about performed bug fixes 
and improvements.
https://cwiki.apache.org/confluence/display/WW/Version+Notes+2.3.36

All developers are strongly advised to perform this action.

The 2.3.x series of the Apache Struts framework has a minimum requirement of 
the following specification versions: Servlet API 2.4, JSP API 2.0, and Java 6.

Should any issues arise with your use of any version of the Struts framework, 
please post your comments to the user list, and, if appropriate, file a 
tracking ticket.

You can download this version from our download page.
https://struts.apache.org/download.cgi#struts-23x


Kind regards.

I don't think so as even Struts 2 doesn't have such feature. Struts 1 isn't 
supported due to EOL but thanks a lot for your tip which can being applied on 
Struts 2.

RE: Struts2 - multipart/related - HttpServletRequest#getParts not working

[Yasser Zamani]

I see Struts REST plugin has a handler for multipart request but it and even 
the whole Struts framework also talks only about multipart/form-data ;) 
Unfortunately it seems Struts doesn't know such content type at all. Anyway, 
some tips can be found in net via googling "UT010016: Not a multi part request".

RE: Struts2 - multipart/related - HttpServletRequest#getParts not working

This isn't Struts issue but your underlying servlet message. Anyway, what about 
trying Struts itself file upload feature. Then ask that another app to http 
post the file to a file upload action.

RE: Issue with migration 2.3.34 to 2.5.17

[Yasser Zamani]

Please ask such questions at 
user@struts.apache.org

It seems Struts internal CDI has failed due to miss configuration. Please 
increase log level to debug and look for `textProviderFactory` and 
`AnnotationActionValidatorManager` in output.
Please continue at user@struts.apache.org with 
your new findings.

RE: Struts 2.5 S:Select tag with Multiple True

[Yasser Zamani]

I wonder why HTML needs CTRL key when we enable multiple! Anyway, I think it's 
out of Struts business as an HTML issue. Unfortunately Struts Select tag 
doesn't provide an optional fix for this HTML issue and you've to fix it 
manually via some javascript coding e.g. save current selected items on each 
click and reselect all of them on each click too.

The maven pom.xml is using Struts 2.5.16 but web.xml is using Struts
2.3.x either DTD and filter. The FilterDispatcher is used in the early
Struts2 development, and it’s deprecated since Struts 2.1.3. it’s always
recommended to upgrade the new filter class – StrutsPrepareAndExecuteFilter.

Hello, try browser's developer tools. Open it's network and console tab and 
then click your add button. Then see if any JavaScript error is in console. 
Then check network tab and see what's the response for your server action call. 
I hope these help ☺

But freemarker claims "Java method "AbstractCollection.size()" threw an
exception when invoked on LinkedHashMap$LinkedKeySet object "[]"; see
cause exception in the Java stack trace" and Java stack trace in JSP
exception says "Caused by: java.lang.AbstractMethodError:
java/util/AbstractCollection.size()I". Maybe that JSP exception isn't
for that freemarker exception but it's an unlikely guess from me.

Maybe. I see freemarker search superclasses for methods because class
LinkedHashMap$LinkedKeySet is private. I'm not sure or check if it
always find more specific method!

It seems IBM JDK 8 has different behavior than Oracle or OpenJDK 8. Your
exception claims that JDK is not able to call abstract method size on
LinkedKeySet but here, Oracle and OpenJDK 8 are able to run:

LinkedHashMap lhm = new LinkedHashMap();
Object ks = LinkedHashMap.class.getMethod("keySet").invoke(lhm);
System.out.println("COPY ME 1: " + ks.getClass());
Method m = AbstractCollection.class.getMethod("size");
System.out.println("COPY ME 2: " + m);
Object s = m.invoke(ks);
System.out.println("COPY ME 3: " + s);

They prints:

COPY ME 1: class java.util.LinkedHashMap$LinkedKeySet
COPY ME 2: public abstract int java.util.AbstractCollection.size()
COPY ME 3: 0

which means they're able! I don't know if IBM violates Java
Specification here or Oracle and OpenJDK do. Are you able to ask IBM why
above piece of code fails on their JDK 8 and pass on 7?

Thanks in advance!

Thanks. Sorry, for last one, could you check:

java.util.Map lhm = new java.util.LinkedHashMap<>();
Class c = lhm.getClass();
java.lang.reflect.Method m = c.getMethod("keySet");
Object ks = m.invoke(lhm);
Class c2 = ks.getClass();
java.lang.reflect.Method m2 = c2.getMethod("size");
System.out.println("COPY ME 1: " + m2);
Object s = m2.invoke(ks);
System.out.println("COPY ME 2: " + s);

and if were successful, then check in your action method if:

java.util.Map lhm = this.getFieldErrors()
Class c = lhm.getClass();
java.lang.reflect.Method m = c.getMethod("keySet");
Object ks = m.invoke(lhm);
Class c2 = ks.getClass();
java.lang.reflect.Method m2 = c2.getMethod("size");
System.out.println("COPY ME 1: " + m2);
Object s = m2.invoke(ks);
System.out.println("COPY ME 2: " + s);

is also successful.

Re: s:fielderror not working in Java 8, WebSphere

Sorry. Could you please check this updated one which is OK here:

  public static void main(String[] args) throws Exception
  {
java.util.Map lhm = new java.util.LinkedHashMap<>();
Class c = lhm.getClass();
java.lang.reflect.Method m = c.getMethod("keySet");
Object ks = m.invoke(lhm);
java.lang.reflect.Method m2 = m.getReturnType().getMethod("size");
System.out.println("COPY ME 1: " + m2);
Object s = m2.invoke(ks);
System.out.println("COPY ME 2: " + s);
  }

then reply back COPY MEs values please. Here I get:

COPY ME 1: public abstract int java.util.Set.size()
COPY ME 2: 0

Thanks. Could you also check if your IBM JDK 8 is able to run this:

java.util.Map lhm = new

No. Additionally Struts RequestAware method signature is
setRequest(Map request); i.e. it's parameter is Map not
ServletRequest.

> Any insights as to why this additional setRequest method causes the problem? 

Yes. It's same as your issue with username/password copy from previous
action. Your previous action is in value stack (I don't know why! see
[1]) ChainingInterceptor thinks it's a chain result, so, calls
getRequest on previous action and then calls setRequest on your current
action with returned value (i.e. copies this value from previous action
and overrides your private request field inside your action).

You can fix this also by removing getRequest method which disables
ChainingInterceptor to copies this.

But you may encounter several same issues when you have both setX and
getX methods on your actions.

[1] So, as I mentioned before, could you please rewrite all of your
FORWARDs with Struts ServletRedirect or PostBack results (also revert
back all removed getter methods)? this shows us if FORWARDs are root
cause of these issues or not. Then we can investigate more on other
possible causes.

Regards.

Could you see if "Best Practices: Cross-Context Dispatching and Session
