【问题描述】：
我正在学习 RESTFUL Webservice，我正在 OpenShift 的免费主机上构建一个简单的应用程序
我在 OpenShift 上的服务器和数据库：jbossews-2.0 (Tomcat 7)； postgresql-9.2 This is my Java build path This is my lib
当我在 localhost 测试时，我没有收到错误，但是当我在 OpenShift Host 上运行应用程序时，我在页面上看到：
HTTP Status 500 - java.lang.NoClassDefFoundError: java/time/temporal/TemporalField
type Exception report
message java.lang.NoClassDefFoundError: java/time/temporal/TemporalField

PS：我在 WEB-INF 库中将文件 postgresql-9.4.1208.jar（用于 jdk 8）更改为 prostgresql-9.4.1208.jre7.jar（用于 jdk 7），现在一切正常。 非常感谢大家！玩得开心！！！
【问题讨论】：
-
您使用的是哪个 jboss 墨盒？
-
java.time.temporal.TemporalField确实存在自 Java 1.8 以来。
