提问by haircode

I am getting a show-stopping error trying to obtain JSON output from a basic JAX-RS setup. I am trying Netbeans' Web Services wizards which has generated this default 'service' code:

我在尝试从基本 JAX-RS 设置获取 JSON 输出时遇到显示停止错误。我正在尝试生成此默认“服务”代码的 Netbeans 的 Web 服务向导：

package service;

import entities.Manufacturer;
import java.util.List;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.ws.rs.Consumes;
import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;


@Stateless
@Path("entities.manufacturer")
public class ManufacturerFacadeREST extends AbstractFacade<Manufacturer> {

    @PersistenceContext(unitName = "RestDemoPU")
    private EntityManager em;

    public ManufacturerFacadeREST() {
        super(Manufacturer.class);
    }

    @POST
    @Override
    @Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public void create(Manufacturer entity) {
        super.create(entity);
    }

    @PUT
    @Path("{id}")
    @Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public void edit(@PathParam("id") Integer id, Manufacturer entity) {
        super.edit(entity);
    }

    @DELETE
    @Path("{id}")
    public void remove(@PathParam("id") Integer id) {
        super.remove(super.find(id));
    }

    @GET
    @Path("{id}")
    @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public Manufacturer find(@PathParam("id") Integer id) {
        return super.find(id);
    }

    @GET
    @Override
    @Produces({MediaType.APPLICATION_JSON})
    public List<Manufacturer> findAll() {
        return super.findAll();
    }

    @GET
    @Path("{from}/{to}")
    @Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    public List<Manufacturer> findRange(@PathParam("from") Integer from, @PathParam("to") Integer to) {
        return super.findRange(new int[]{from, to});
    }

    @GET
    @Path("count")
    @Produces(MediaType.TEXT_PLAIN)
    public String countREST() {
        return String.valueOf(super.count());
    }

    @Override
    protected EntityManager getEntityManager() {
        return em;
    }

}

The error is showing up when I remove the @Producesannotation for MediaType.APPLICATION_XMLin the findAll()method to leave MediaType.APPLICATION_JSON(I only want JSON output).

当我在要离开的方法中删除@Produces注释时出现错误（我只想要 JSON 输出）。MediaType.APPLICATION_XMLfindAll()MediaType.APPLICATION_JSON

XML is fine - the JSON-only annotation raises a HTTP Status 500 - Internal Server Errorwith Java exception: javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: org/xml/sax/helpers/DefaultHandlererror.

XML 很好 - 仅 JSON 注释引发了HTTP Status 500 - Internal Server ErrorJava 异常：javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: java.lang.NoClassDefFoundError: org/xml/sax/helpers/DefaultHandler错误。

This is a known bug in GlassFish https://java.net/jira/browse/GLASSFISH-21440the bug is actually in EclipseLink and there is a workaround described in the GlassFish bug report above.

这是 GlassFish https://java.net/jira/browse/GLASSFISH-21440 中的一个已知错误，该错误实际上位于 EclipseLink 中，上面的 GlassFish 错误报告中描述了一种解决方法。

You could try upgrading to Payara Server where this bug is fixed.

The problem is a missing jar file ( Hymanson-module-jaxb-annotations ) in glashfish 4.1.1. You can download it from this link http://www.java2s.com/Code/Jar/j/DownloadHymansonmodulejaxbannotations212jar.htmor google download Hymanson module jaxb annotations. Then include it in C:\Program Files\glassfish-4.1.1\glassfish\modules director. you can rename the jar file by removing the version number. Restart glassfish and redeploy your app. It works for me that way

问题是 glashfish 4.1.1 中缺少 jar 文件 ( Hymanson-module-jaxb-annotations )。你可以从这个链接下载它http://www.java2s.com/Code/Jar/j/DownloadHymansonmodulejaxbannotations212jar.htm或谷歌下载 Hymanson 模块 jaxb 注释。然后将其包含在 C:\Program Files\glassfish-4.1.1\glassfish\modules 目录中。您可以通过删除版本号来重命名 jar 文件。重新启动 glassfish 并重新部署您的应用程序。它对我有用
