QUESTION
We have a Struts2 application where we are building survey feature using which application users will be able to create surveys by adding different questions.
These questions are comprised of question text and an html control for getting response.
The html controls so far supported are single and multi-select list, text field, textarea, checkbox and radiobox.
So the survey form renders displaying all questions added by the user where each question has its question text displayed followed by the html field control selected for that question.
Basically, it is a dynamic form where form field names are being dynamically generated as all surveys will be different and therefore there are no properties in the Action class backing survey form fields.
We are generating form field name using prefix question_
appended with database id of the question to represent each question response input field uniquely. Here is a snippet from our JSP page to make things clear.
ANSWER
Answered 2021-Dec-23 at 10:13We have finally solved the problem. The initial implementation was heading in a completely wrong direction but thanks to the clue from @RomanC, we re-factored the code and removed the direct use of HttpServletRequest
to finally have a working solution. Core idea was to use a Bean for capturing response and have a List
of those beans in the Action class corresponding to each survey question. On form submit, response is captured into the bean objects behind the scene by framework itself and thus available for further logic processing in submit handler action method.
QUESTION
I am doing a Struts 1 to Struts 2 migration. We have Struts 1 code that has extended and customised the org.apache.struts.taglib.html.FormTag
. Did some search and found that the org.apache.struts2.views.jsp.ui.FormTag
is the equivalent in Struts2.
My current Struts 1 code modifies the onsubmit
variable of the FormTag
by calling the setOnsubmit()
, but it does that by first doing a getOnsubmit()
like below.
ANSWER
Answered 2021-Dec-10 at 14:40The tag belongs to Struts 2 core tag library. So, if you need to use your own tag that extends this one then you should extend
org.apache.struts2.views.jsp.ui.FormTag
class and provide your own implementation by overriding public
methods, and adding additional methods. The onsubmit
field has a protected
modifyer.
But before doing any changes to the Struts 2 framework ask an advice from qualifyed experts: why do you need to do it? For carrying the old code to the new one? The code that is written for S1 is incompatible with S2.
onsubmit
is a HTML attribute of the HTML
Also when migrating from Struts1 to Struts 2 you should read Struts 1 to Struts 2 migration strategy.

As for as I know, Struts2's type converter will work like this :
I declared a map Map a4booking
in my OrderContext
's field, and in my JSP file the input tag's name is orderContext.a4booking.name
and user entered 'Daniel', after submitting the , the a4booking
map will have a key:value
like { "name" : "Daniel" }
, so the 'name' will become a key.
Now, when I declared a List> datas

QUESTION
Hi We have recently upgraded Struts2 from Struts 2.5.22 to 2.5.27 . In our application we are are using Struts Jquery Grid. We are using struts2-jquery-grid-plugin-4.0.3.jar library.
One of our application need is to assign grid id a dynamic value which is bean property. My code snippet is below:
...ANSWER
Answered 2021-Dec-04 at 16:27Since Struts 2.5.26 you no longer can use %{}
to force OGNL evaluation in the Struts tags using public attributes which leads to double evaluation of OGNL expression. This fixture is documented in S2-061.
Some of the tag's attributes could perform a double evaluation if a developer applied forced OGNL evaluation by using the
%{...}
syntax. Using forced OGNL evaluation on untrusted user input can lead to a Remote Code Execution and security degradation.
QUESTION
I need to post a simple json object to a Struts 2 action, could you tell me what I miss with this:
the Java object to save:
...ANSWER
Answered 2021-Nov-26 at 23:15The methods that are mapped to the actions not use any parameters in the method signature. So you need to remove those parameters and add json
interceptor to the action config.
This field is used as root
object by the json interceptor and should not be null
.

I have a product table whose data is taken from mysql. The button is associated with an action that redirects to a jsp that shows that the product has been purchased. I need this action to create a table where it inserts the id of the customer and the product. My problem is being able to retrieve the id for that product.

...ANSWER
Answered 2021-Nov-08 at 09:34You need to send the id of the selected item to the action, otherwise it won'T know what was selected. You could do this in at least 2 ways:
- Submit a form instead of using a link and put the id into a hidden form field
Something like this (I didn't use Struts2 in a while so there may be errors):
