PS：我改变文件postgresql-9.4.1208.jar（用于jdk 8）到我的WEB-INF库中的prostgresql-9.4.1208.jre7.jar（用于jdk 7），现在一切正常。 非常感谢大家！玩的很开心 ！！！

根据Java docs的time/temporal/TemporalField已于版本1.8
介绍我创建一个Tomcat 7（JBoss的EWS 2.0）的墨盒并检查版本：
$ ssh $MY_APP
$ java -version
java version "1.7.0_95"
+0
是的，我也这么认为。但我无法找到问题的解决方案:(（（ – TearsRiver

完成，感谢您的帮助;） – TearsRiver

更改为9.4.1208.jre7解决了我问题，似乎他们编译为jdk8

在我的情况下（SLES 11.3上的Tomcat 8），事实证明，虽然我已经安装了Java 8 SDK而不卸载Java 7，并相应地设置了JAVA_HOME，但JRE_HOME是s直到指向我的Java 7安装。解决这个问题。
您使用哪种jboss墨盒？ –
'java.time.temporal.TemporalField'仅在Java 1.8以后才存在。 – Berger
