eclipselink PersistenceUnitLoadingEception in WAR file?

Question

我得到一个非常类似的错误，这个问题:eclipselink PersistenceUnitLoadingEception在可执行JAR.

我正在部署WAS Liberty Profile V8.5。

当我的项目导出到一个WAR文件;我没有更换包装的选项。我不确定什么是错的，包装风格之间的区别是什么。即使是这样……我所有的依赖项(jar文件)都在server.xml中指定的目录中，所以我只能说我很困惑。

错误:

当我解压缩war文件时，persistence.xml文件的位置是:
web - inf/classes/meta - inf/persistence . xml
还有:/META-INF/MANIFEST。MF

我不确定这是否有区别，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，它可以完美地工作!(注意，当你简单地按下'run on server'时，这是默认的方式)。

WebApiConsole.war.xml:

<?xml version="1.0" encoding="UTF-8"?>
<archive>
    <dir sourceOnDisk="C:eclipseworkspaceWebApiConsoleWebContent" targetInArchive="/"/>
    <dir sourceOnDisk="C:eclipseworkspaceWebApiConsoleWebContentWEB-INFclasses" targetInArchive="/WEB-INF/classes"/>
</archive>

下面是过滤器文件:

@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() { }
}

这看起来像是EclipseLink的错误。您可以向EclipseLink用户邮件列表发布一些内容吗?我去那边接你。

在调试这个问题后，这是一个在websphereliberty测试版中已经修复的问题，并于2014年8月15日公布。
