我刚刚安装了activemq，但是当我尝试运行以下命令时：
./activemq start xbean:file:workspace/activemq/apache-activemq-5.9.0/conf/activemq.xml
我得到以下内容：
emq/apache-activemq-5.9.0/conf/activemq.xml
INFO: Loading '/etc/default/activemq'
INFO: Using java '/usr/bin/java'
INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details
INFO: pidfile created : '/home/pi/workspace/activemq/apache-activemq-5.9.0/data/activemq-pi.pid' (pid '2576')
activemq/apache-activemq-5.9.0/bin/activemq status returns the following:
INFO: Loading '/etc/default/activemq'
INFO: Using java '/usr/bin/java'
ActiveMQ not running
activemq.log说明如下：
Caused by: java.io.FileNotFoundException: workspace/activemq/apache-activemq-5.9.0/conf/activemq.xml./activemq (No such file or directory)
但是activemq.xml文件在那里？我对activemq很新，不知道从哪里开始，谢谢。
