The request sent by the client was syntactically incorrect

[Muhammad Ramahy]

I have this javascript code:
$(document).ready(function(){ $("#tweet").click(function(){ if ($("#textarea").val().trim() == "") { //do nothing }else { $("#feeds").after("<tr><td>"+$("#textarea").val()+ "</td></tr>" +"<tr><td>"+new Date()+"</td></tr>"); $.ajax({ type : "POST", url : "/tweety-0.0.1-SNAPSHOT/twitter/tiles/home#", data : { message : $("#textarea").val(), username: $("#username").val() } }) } $("#textarea").val(""); });
this code is to send some text to save in the database and I send it via ajax call as demonstrated this js code goes to controller method below:

@RequestMapping(value="/home#",method=RequestMethod.POST)
	public @ResponseBody void saveMessage(@RequestParam("username") String username,
			@RequestParam("message") String message){
		System.out.println("directed to controller");
		service.saveMessage(message,username);			
	}

as you can see I am using spring 3.0 with annotations
my problem is that every time I fire the js code it gives me : error 400- The request sent by the client was syntactically incorrect
and I don't know any clue so I need help

While this might not solve your problem, one thing I see.

You are using @RequestParam as if those values are directly in the URL string as request parameters. So after the URL part you would have to have ?userName=someValue&message=MessageValue for @RequestParam to get those values. If those values aren't in the URL after the ? then they aren't Request Params.

Where is that data? Is it in the RequestBody? Is it a ModelAttribute? If so , then use its corresponding annotation, @RequestBody or @ModelAttribute

I think it is a combination of the message being sent Message meaning URL and contents, not your variable message. And also in the Controller annotations that you are using are incorrect.
