struts multibox example

Struts multibox [multiple check boxes] example

1. create a memeber variables and respective setters and getters in any form class like below

import org.apache.struts.action.ActionForm;
   public class LanguageForm extends ActionForm
    private String[] selectedLanguages = {}; 
 private String[] languages = {"Java","J2EE","JSP","STRUTS","Spring"}; 
 public String[] getSelectedLanguages() {
  return selectedLanguages;

 public void setSelectedLanguages(String[] selectedLanguages) {
  this.selectedLanguages = selectedLanguages;

 public String[] getLanguages() {
  return languages;

 public void setLanguages(String[] languages) {
  this.languages = languages;

2. Add below code inside action class to display languages in JSP

public class LanguageAction extends Action {
 private static final String SUCCESS = "success";

 public ActionForward execute(ActionMapping mapping, ActionForm form,
   HttpServletRequest request, HttpServletResponse response)
   throws Exception {
          String selectedLanguageValues="";
    LanguageForm languageForm = (LanguageForm)form;
   for (String selectedLanguage : languageForm.getSelectedLanguages()) {
    selectedLanguageValues = selectedLanguageValues.concat(selectedLanguage+",");
   if(selectedLanguageValues != null && !selectedLanguageValues.isEmpty()){
    selectedLanguageValues = selectedLanguageValues.substring(0,selectedLanguageValues.length()-1);
   return SUCCESS;

3. JSP code as mentioned below

<%@taglib uri="" prefix="html"%>
         <%@taglib uri="" prefix="bean"%>
         <%@taglib uri="" prefix="logic"%>
