This question already has an answer here: Passing parameters in URL without query string in Struts 2 2 answers If I have a url: www.myurl.com/books and want to be able to create new <s:url> filtering on author and year: www.myurl.com/books/Sartre/1942 by passing Sartre and 1942 as parameters to the action class which will render the books page with the appropriate results. How to do this in Struts2? I have the backend logic in place so it would be great if: I could reuse the same jsp and action class that the permalink www.myurl.com/books uses. Show the dynamically rendered URL www.myurl.com

This is the form I am using to repopulate the ArrayList <form method = "POST" action = "addItemsToTemplate"> <s:iterator value = "myQuestions" var = "quizItem" status="key"> <s:textfield name = "quizItem.question"/> </s:iterator> <input type = "submit" value = "submit"/> </form> This is the action class public class QuizTest extends ActionSupport{ public String execute(){ List<Question> q= myQuestions; System.out.println(myQuestions); return "success"; } public String populateQuestions(){ //more code here } public void setMyQuestions(List<Question> myQuestions) { this.myQuestions = myQuestions

I can't believe how something this simple can seem so hard to do in Struts 2. This is approximately what I would like to do as it would be done in Java. for (Parent parent : parents){ for (Child child: parent.getChildren()){ System.out.println(child.getName()); } } That should translate to something close to this in Stuts tags: <s:iterator var="parent" value="parents"> <s:iterator var="child" value="parent.children"> <s:property value="child.name"/> <s:iterator> <s:iterator> I assume parent.children should be something like ${%(#parent.children)} but I have not found a right combination of ${%

I am doing a project using Struts2 and I have a problem assigning a set collection. Here's my Action (I eliminated the irrelevant part) public class TeamAction extends BaseAction implements ModelDriven<Team> { Team team=new Team(); } Here's my model Team (I eliminated the irrelevant part) private TeamId id; private Set students = new HashSet(0); Here's my JSP part <input type="text" name=team.student[0].id /> Now the problem is I can't insert the right value into this Set collection in by ModelDriven , it will throw a exception.

As mentioned in http://www.disasterarea.co.uk/blog/xss-vulnerabilities-in-web-frameworks-2/ The ${} is not xss safe in struts 2 while it is safe in tapestry 5. I am not a Tapestry guy, but I want to know if above is correct. As far as I know the ${} is part of JSLT and it does not depend on any web frameworks. So if above sentence is correct and the ${} is XSS safe in tapestry, how can we make it safe in struts 2. Updated: To test it I run struts2-showcase app, opened modelDriven\modelDrivenResult.jsp and add below line: Am I safe ${name} Now when you run the show case and enter <script> alert

I'm trying to create a dynamic variable in Struts2 using set tag <s:set var="myNum" value="numConst" /> <s:set var="number" value="%{getText('@xxx.CommonConstant@'+#myNum)}" /> numConst will return a dynamic value that retrieved from database. For example, if the value is NINE then number should be @xxx.CommonConstant@NINE I have set the value in my java class so that @xxx.CommonConstant@NINE will return 9 . So far, the value can be displayed with no problem in text tag if I use <s:text name="%{getText(#number)}" /> It will return 9 but it displayed incorrectly when I tried using property tag
