java jersey服务器端错误（500）参数错误？

Question

嗨有标题说我有几个问题。我的客户端不断出现错误500，但不确定服务器中出现错误的是什么。我认为这可能是通过的参数，但我不确定。我在客户端也有注释代码的问题，但我认为这是参数特别但现在我遇到了一个问题（在客户端的主体中没有注释的代码）所以现在我不知道在哪里继续从这里。我想这可能是路径，但我想我只需要一双新的眼睛来指出我犯了什么愚蠢的错误。请告诉我你的想法和答案如下。谢谢！

客户端

public class Tester {

private static URI getBaseURI(){
    return UriBuilder.fromUri("http://localhost:8080/Assignment-tomcat_with_custom_api").build();
}

public static void main(String[] args){

    ClientConfig config = new DefaultClientConfig();
    Client client = Client.create(config);
    WebResource service = client.resource(getBaseURI());

    /*
    //example of creation
    Film film = new Film(50000000, "film1", 1155, "film1", "film1", "film1");
    ClientResponse response = service.path("rest").path("films").path(""+film.getId()).accept(MediaType.APPLICATION_XML).put(ClientResponse.class, film);
    if(response.getStatus() == 201){
        System.out.println("Film has been created");
    }else{
        System.out.println("Film had failed to be created. Response status:"+response.getStatus());
    }
    */

    System.out.println();
    //get all films
    System.out.println(service.path("rest").path("films").accept(
            MediaType.TEXT_XML).get(String.class));

}
