Pass arraylist from one JSP to another

Question

Hi all,
I have a jsp in which i have a table with a list a of users. When we select some users and click on the deactivate link all these user information must be passed to another jsp which is a confirmation page to delete the users.
In my first userlist jsp i have the code
<h:commandLink styleClass="bold" value="Deactivate User" action="delete" actionListener="#{userlistcontroller.deleteaction}" ></h:commandLink>faces-config.xml
    <navigation-rule>
    <from-view-id>/userlist.jsp</from-view-id>
    <navigation-case>
      <from-outcome>delete</from-outcome>
      <to-view-id>/deactivateusers.jsp</to-view-id>
    </navigation-case>
  </navigation-rule>In my backing bean action method i populate the list of users that need to be deacivated in an array list
   String userAction;
   List<Integer> selectedUserIDList;
   public void deleteaction(ActionEvent event){
       userAction = "delete";
       selectedUserIDList = new ArrayList<Integer>();
       for (CompanyAdminUser user : userList) {
             try {
                boolean val = selectedIds.get(user.getID()).booleanValue();
           if(val){
                selectedUserIDList.add(user.getID());
             } catch (Exception e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
  }can someone help me how to pass this selectedUserIDList (arraylist ) and the userAction="Delete" to deacviate users jsp.
Thank you

Answer 1

You can easily pass the 2 variables you mentioned using <f:param> inside your <h:commandLink>.
<h:commandLink styleClass="bold" value="Deactivate User" action="delete" actionListener="#{userlistcontroller.deleteaction}" >
<f:param name="userAction" value="delete" />
<f:param name="userIDList" value="#{userlistcontroller.selectedUserIDList}" />
</h:commandLink>
