I trying to populate the dropdown list when page was loaded.But it is not loaded in UserPage.jsp from Controller.on submit method and also wrote referencedata method.
Controller:-
public ModelAndView onSubmit(HttpServletRequest request,
HttpServletResponse response, Object command, BindException errors)
throws Exception {
log.info("onSubmit handleRequest method"
+ request.getParameter("username"));
System.out.println("onSubmit handleRequest method"
+ request.getParameter("username"));
String username = "", password = "";
username = request.getParameter("username");
password = request.getParameter("password");
UserBean ubean = null;
System.out.println("After shownform method called");
HttpSession session = request.getSession(true);
try {
ubean = userservice.chkUsername(username, password);
System.out.println("Information" + ubean.getUsername());
} catch (DataException ex) {
ex.printStackTrace();
// throw ex;
}
session.setAttribute("User", ubean);
EmpPersonalBean personalBean = new EmpPersonalBean();
return new ModelAndView("jsp/UserPage", "EmpPersonalBean", personalBean);
}
protected Map referenceData(HttpServletRequest request) throws Exception {
log.info("UserDBBoardController======================referenceData");
Map referenceData = new HashMap();
List deparementList = new ArrayList();
deparementList = userservice.getDeparmentList();
referenceData.put("deparmentList", deparementList);
return referenceData;
}

}
}
And also attached displaying dropdown list in the userpage.sjp
Please help me.How to resolve the issue.
You also need to specify itemLabel and itemValue attributes in
<form:options/>tag.UPDATE
Replace this line in your jsp page. I think it should resolve your problem.
Hope this helps you. Cheers.
