Trying to use Ajax, Spring, REST and JAXB but getting Errors……. I am trying to do a REST call from Ajax to Spring. I am getting the following errors..
Here is my JSP:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>This is a project to show how to use RESTful</title>
</head>
<body>
<script type="text/javascript">var contexPath = "<%=request.getContextPath()%>";</script>
<script src="<%=request.getContextPath()%>/js/jquery.js"></script>
<script type="text/javascript">
function doAjaxPost() {
alert("doAjaxPost Called");
var queryString = $('#htmlform').serialize();
$.ajax({
contentType : "application/json",
dataType : 'json',
type : "PUT",
url : contexPath + "/service/employee",
data : queryString, //json serialization (like array.serializeArray() etc)
success : function(data) {
alert("Thanks for submitting. \n\n" + response.result);
// response
},
error : function(request, status, error) {
alert('Error: ' + e);
}
});
}
</script>
<H1>Add Employee</H1>
<p>
<form name="htmlform">
<table border=1>
<thead><tr>
<th>ID</th>
<th>Name</th>
<th>Email</th>
</tr></thead>
<tr>
<td><input type="text" name="ID" maxlength="5" size="3"></td>
<td><input type="text" name="Name" maxlength="10" size="10"></td>
<td><input type="text" name="Email" maxlength="10" size="10"></td>
</tr>
</table>
<input type="button" value="Save Employee" onclick="doAjaxPost();" />
<p>
<p>
</form>
[<a href="http://localhost:8080/RESTful/service/employees">List all Employees</a> | <a href="add.jsp">Employee Form Test</a>]
</body>
</html>
here is the code that is in my controller:
@RequestMapping(method=RequestMethod.PUT, value="/employee")
public ModelAndView updateEmployee(@RequestBody String body) {
System.out.println("in put");
Source source = new StreamSource(new StringReader(body));
Employee e = (Employee) jaxb2Mashaller.unmarshal(source);
System.out.println(e.toString());
return new ModelAndView(XML_VIEW_NAME, "object", e);
}
and now for the error….

It looks like you’re sending the object in json format and trying to unmarshal it with jaxb (xml). It obviously gives you an exception.
If you have jackson in the classpath, the unmarshalling from JSON should be automatic. You only need to have a parameter
@RequestBody Employee employeeinstead of@RequestBody String body
