Jakarta ee eclipselink PersistenceUnitLoadingEception在WAR文件中？

我得到了一个与这个问题极其相似的错误：

我正在WAS Liberty Profile V8.5上部署

但是，当将我的项目导出到WAR文件时；我没有改变包装的选择。我不确定是什么错了，以及包装风格之间的区别是什么。即使如此……我的所有依赖项jar文件都在server.xml中指定的目录中，所以我很困惑

错误：

解压war文件时，persistence.xml文件的位置为： WEB-INF/classes/META-INF/persistence.xml 还有：/META-INF/MANIFEST.MF

我不确定这是否会产生影响，或者告诉eclipse停止制作这个额外的META-INF文件夹

有趣的是，当我简单地构建我的项目并使用.xml扩展来引用我的类时，它工作得非常好！注意，当您只需按“在服务器上运行”时，这是默认方式

WebApiConsole.war.xml：

<?xml version="1.0" encoding="UTF-8"?>
<archive>
    <dir sourceOnDisk="C:\eclipse\workspace\WebApiConsole\WebContent" targetInArchive="/"/>
    <dir sourceOnDisk="C:\eclipse\workspace\WebApiConsole\WebContent\WEB-INF\classes" targetInArchive="/WEB-INF/classes"/>
</archive>

以下是筛选文件：

@WebFilter(description = "This filter intercepts all requests to the restful"
        + "webservice and checks whether the user is in the database", urlPatterns = { "/rest/*" })
public class AuthorizationFilter implements Filter {

    private static final String identifierCookieDomain = "null";
    private static final String identifierCookieName = "UID";
    private EntityManager em;

    public AuthorizationFilter() {}

    @PostConstruct
    public void init() {
        em = Persistence.createEntityManagerFactory("ConsoleManagement").createEntityManager();
    }

    public void doFilter(ServletRequest request,
                         ServletResponse response,
                         FilterChain chain) throws IOException, ServletException {
        Cookie[] cookies;
        String uid = null;

        cookies = ((HttpServletRequest) request).getCookies();
        if ( cookies == null ) {
            ((HttpServletResponse) response).sendError(401, "Unauthorized Access: Please login");
        } else {

            uid = getCookie(request, identifierCookieDomain, identifierCookieName);

            if ( uid == null || !userExists(uid)) {
                ((HttpServletResponse) response).sendError(401, "Unauthorized Access: Please login");
            } else {
                chain.doFilter(request, response);
            }   
        }
    }

    public boolean userExists(String uid) {
        List<User> users = em.createNamedQuery("User.queryUserByUid", User.class)
                .setParameter("uid", uid)
                .getResultList();
        if (users.size() == 0) return false;
        return true;
    }

    public String getCookie(ServletRequest request, String domain, String name) {
        String value = null;
        Cookie[] cookies = ((HttpServletRequest) request).getCookies();
        for(Cookie cookie : cookies) {
            String cookieDomain = cookie.getDomain() == null ? "null" : cookie.getDomain();
            String cookieName = cookie.getName() == null ? "null" : cookie.getName();
            if ( cookieDomain.equals(domain) &&
                    cookieName.equals(name) ) {
                value = cookie.getValue();
                break;
            }
        }
        return value;
    }

    public void init(FilterConfig fConfig) throws ServletException {}

    @Override
    public void destroy() { }

}

这看起来像一只食虫。你能在邮件列表上贴些东西吗？我会在那边跟你联络

[更新]

调试该问题后，WebSphereLiberty中的问题已在中修复

[/Update]

您是在Liberty beta版中使用jpa-2.1，还是自己打包EclipseLink并在特定Liberty版本中使用jpa-2.0？哪个版本显示在messages.log的顶部？我已经打开了jpa-2.1功能。很抱歉，在messages.log顶部找不到版本。根据要求，我发布了该问题。我还没有在列表中看到它。。。我想你必须先订阅才能发布。很有趣。。。我会订阅的。完成。很抱歉，gmail将失败过滤到了促销活动中
