I am developing my project in Eclipse and have configured my Weblogic-12.1.3server in Eclipse. I am not sure why this error is happening, but I expect its because my java version is 1.8, and maybe it expects me to use java 1.6 which I think comes with Weblogic installation.
我正在 Eclipse 中开发我的项目并在 Eclipse 中配置了我的Weblogic-12.1.3服务器。我不确定为什么会发生这个错误，但我希望它是因为我的 java 版本是 1.8，也许它希望我使用 java 1.6，我认为它是 Weblogic 安装附带的。
java -version
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)

You must typecd WLS_home/user_projects/domains/mydomain/bin/
你必须输入cd WLS_home/user_projects/domains/mydomain/bin/
. ./setDomainEnv.sh
. ./setDomainEnv.sh
You must use two separate dots, that should do the trick!
您必须使用两个单独的点，这应该可以解决问题！
