使用JSTL自动完成

Question

不确定是否可行，如果我有以下autoComplete代码，我如何在jstl代码中使用它来实现相同的目的？或者还有其他方法可以实现这一目标吗？

<input type="text" id="department" name="department"/>

<script>
    $("#department").autocomplete("getdept.jsp",{minChars: 4});
</script>

并在getdept.jsp

DepartmentMB dept = new DepartmentMB ();
String query = request.getParameter("q");
List<String> dep = dept.getData(query);

Iterator<String> iterator = dep .iterator();
while(iterator.hasNext()) {
    String department = (String)iterator.next();
    String deptName=(String)it.next();
    out.println(deptName);

}
