我对一个Glassfish-Server有点奇怪的问题,不知道在哪里,在哪里寻找。

在Ubuntu Ubuntu 14.04.4上LTS,Glassfish 4.1,OpenJDK 1.7(或Oracle JDK 1.8)我在访问mysql数据库时遇到以下异常:

                int        entryCodeId,
                BigDecimal amountFix,
                BigDecimal amountVar,
                Date       validFrom,
                Date       validThru) {

        javax.persistence.Query q = getEntityManager().
                      createNamedQuery("EntryCodeAmounts.terminateLast").
                        setParameter("entryCodeId", entryCodeId).
                        setParameter("validThru", validFrom);
        q.executeUpdate();

        EntryCodeAmounts ecAmounts = new EntryCodeAmounts();
        ecAmounts.setEntryCodeId(entryCodeId);
        ecAmounts.setAmountVar(amountVar);
        ecAmounts.setAmountFix(amountFix);
        ecAmounts.setValidFrom(validFrom);
        ecAmounts.setValidThru(validThru);
        getEntityManager().persist(ecAmounts);
    }
}

对其他表/实体类的所有其他访问都正常工作。

我相信你被击中https://java.net/jira/browse/GLASSFISH-21468这只是一个可以忽略的警告。在部署持久性单元时会发生此NPE,这仅在第一次访问时发生。并通过服务器平台检测方法捕获并记录,然后正常进行部署。
