Question

我尝试将我在Wildly / Hibernate上运行良好的java ee应用程序部署到GlassFish / EclipseLink，并且我收到了这样的错误：

Problem compiling [DELETE FROM ProviderService ps WHERE :work_station MEMBER OF ps.workStations AND ps.workStations.size = 1].
[81, 101] The state field path 'ps.workStations.size' cannot be resolved to a valid type.
 81, 101] The state field path 'ps.workStations.size' cannot be resolved to a valid type.

是否有可能用冬眠来运行玻璃鱼？如果是这样，我怎么能在build.gradle中配置这样的东西。

我正在使用build.gradle条件选择Wildfly远程/ Wildfly嵌入式测试用Arquillian（工作正常），现在添加Glassfish远程/ Glassfish嵌入但在这里我无法编译有这样的错误如上。我也收到这样的东西：

    ArquillianServletRunner not found. Could not determine ContextRoot from ProtocolMetadata, please contact DeployableContainer developer.
java.lang.IllegalArgumentException: ArquillianServletRunner not found. Could not determine ContextRoot from ProtocolMetadata, please contact DeployableContainer developer.

JPQL无效。 JPQL由JPA规范定义，并且为了便携性，您必须坚持正确的语法。在这种情况下，有一个功能＆＃34; SIZE＆＃34;。应该是

DELETE FROM ProviderService ps WHERE :work_station MEMBER OF ps.workStations AND SIZE(ps.workStations) = 1

EclipseLink @OneToMany关系大小为JPQL异常
