How to use “s:checkbox” in Struts 2 in iterator

When you have requirement to use “s:checkbox” as a iterator / multiple / group wise, How you will use it?

Here is the sample example or way to it:

Step 1: Create List of “String” in you action file like:

private List symptomCheckBoxList = new ArrayList();

And create it’s getter and setter.

Step 2: Put “s:checkbox” into your “s:iterator”
Like:

Here symptomList in s:iterator is the list “private List symptomList = new ArrayList();” which is having generic type “Symptom” POJO for this list in your action file.

‘ s:property value=”symptomName” ‘ is the value to display for checkbox and here it is property type String into the Symptom POJO.

And “symptomCheckBoxList” is the list in which you will get the the selected / checked value from the display list. It must be in string format.
