       property = {
       "com.liferay.portlet.display-category=category.sample",
       "com.liferay.portlet.instanceable=true",

       "javax.portlet.resource-bundle=content.Language",
       "javax.portlet.security-role-ref=power-user,user"
       },
       service = Portlet.class
      )
      public class LeavePortlet extends MVCPortlet {
       
      }

   1. @Component(
       property = {
       "javax.portlet.name=org_javasavvy_web_leave_portlet",
       "mvc.command.name=leave_editLeave"
       },
       service = MVCActionCommand.class
       )
      public class EditLeaveActionCommand extends BaseMVCActionCommand {
      
       private LeaveLocalService leaveService;
       
       @Reference(unbind = "-")
       protected void setLeaveService(LeaveLocalService leaveService) {
      
       this.leaveService = leaveService;
       }
       
       @Override
       protected void doProcessAction(ActionRequest actionRequest, ActionResponse actionResponse) 
       throws Exception {
       
       SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
       String name = ParamUtil.getString(actionRequest, "name");
       System.out.println("Leave Edit"+name);
       Date startDate= ParamUtil.getDate(actionRequest, "startDate",sdf );
       Date endDate = ParamUtil.getDate(actionRequest, "endDate", sdf);
       
       ThemeDisplay themeDisplay = (ThemeDisplay) actionRequest.getAttribute(WebKeys.THEME_DISPLAY);
       long groupId = themeDisplay.getScopeGroupId();
       
       Leave leave = leaveService.addLeave(name, themeDisplay.getRealUserId(), groupId,
       themeDisplay.getCompanyId(), startDate, endDate);
       
       }
       
      }

3.  In JSP,  portlet action URL should be like belows. We can use either of below action requests:

   1. <liferay-portlet:actionURL name="leave_editLeave" var="editLeave">
           <portlet:param name="mvcActionCommand" value="leave_editLeave" /> 
       </liferay-portlet:actionURL>

   2. <liferay-portlet:actionURL name="leave_editLeave" var="editLeave">
      </liferay-portlet:actionURL>
      <aui:form action="<%= editLeave %>" cssClass="container-fluid-1280" method="post" name="fm">
