如何查看 WebLogic Server的版本号[转]

WebLogic Server 10gR3为例:
1.查看$BEA_HOME/registry.xml
=> <component name="WebLogic Server" version="10.3.0.0" InstallDir="/opt/bea/wlserver_10.3">

2.$BEA_HOME/logs/log.txt
=> 2009-6-19 13:17:00 -- install "WebLogic Platform" 10.3.0.0 at /opt/bea

3. WebLogic Server启动之后，会把版本信息打印到Server日志之中
