Weblogic92选择产品模式的时候，报了一个异常，但是选择开发模式的时候却能正常运行，这是为什么呢？

解决：
在对应的domains目录下，例如
[/prodigy/weblogic/user_projects/domains/devdomain/servers/gxServer1]ls
cache data logs security stage tmp
[/prodigy/weblogic/user_projects/domains/devdomain/servers/gxServer1]cd security
[/prodigy/weblogic/user_projects/domains/devdomain/servers/gxServer1/security]ls
boot.properties
[/prodigy/weblogic/user_projects/domains/devdomain/servers/gxServer1/security]
在此目录下用vi创建文件boot.properties文件，输入如下内容：
username=weblogic
password= weblogic
输入完毕后，保存退出即可
