Compile class issue in Spring 3

I used spring framework 3 for my application. Everything is fine, while in Netbeans But I need a special assembly and is made for it. Created without any, but I got the following error. An error occurred while calling the following method.

@RequestMapping(value = "/security/login", method = RequestMethod.POST) public ModelAndView login(@RequestParam String userName, @RequestParam String password, HttpServletRequest request) { ......................

But there is no problem when creating a war with netbeans (I am sure that this is a compilation problem) Do you have experience in this matter ... Is there any additional javac argument for compiling the same (netbeans is used to compile)

Argument names are stored in compiled code only when it is compiled in debug mode, so you must either compile it in debug mode or put @RequestParam with explicit parameter names. The latter approach is more reliable since it is environment independent:

 @RequestMapping(value = "/security/login", method = RequestMethod.POST) public ModelAndView login(@RequestParam("userName") String userName, @RequestParam("password") String password, HttpServletRequest request) { ......................
