我将Tomcat TOMEE PLUS 8.0.0 M2应用程序服务器和Eclipse Oxygen用于我的REST开发。从REST服务类中，我无法调用JSP文件。
如何解决此问题并从服务类中调用JSP？
在REST服务类中：
List<User> userList=userDao.getAllUsers();
URI uri=null;
try
{
uri = new URI("./UserList.jsp");
}
catch (URISyntaxException e) {e.printStackTrace();}
catch (WebApplicationException we) {we.printStackTrace();}
//URI uri = UriBuilder.fromPath("./UserList.jsp").queryParam("ListOfUser",userList).build();
//return Response.seeOther(uri).build();
return Response.temporaryRedirect(uri).build();
最后一行返回的服务器运行时错误：
