我在这个问题上遇到了一个非常相似的错误：eclipselink PersistenceUnitLoadingEception in executable JAR。
我正在部署WAS Liberty Profile V8.5。
将项目导出到WAR文件时;我无法改变包装。我不确定什么是错的，包装样式之间有什么区别。即便如此......我所有的依赖项（jar文件）都在server.xml中指定的目录中，所以我可以说我很困惑。
错误：

当我解压缩war文件时，我的persistence.xml文件的位置是：
WEB-INF /班/ META-INF / persistence.xml中
还有：/ META-INF / MANIFEST.MF
我不确定这是否有所不同，或者告诉eclipse停止制作这个额外的META-INF文件夹。
有趣的是，当我只是构建我的项目并使用.xml扩展名来引用我的类时，它完美无缺！ （注意，当您简单地按“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>
这是过滤文件：
@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() { }
}
答案 0 :(得分：0)
这看起来像是一个EclipseLink错误。你能发帖到EclipseLink users邮件列表吗？我会在那边跟进你。

调试问题后，WebSphere Liberty中的问题已在Beta that was announced on 8/15/2014.中修复
