问题

但是按照文档中的配置，当试图在windows下监控Tomcat时出现了下面的异常：

Error Connecting to Server ; Failed to connect to service:jmx:rmi:///jndi/rmi://XX.XX.XX.XX 12345/jmxrmi [Nested Exception: 
java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.ServiceUnavailableException
 [Root exception is java.rmi.ConnectException: Connection refused to host: /XX.XX.XX.XX; 
nested exception is: java.net.ConnectException: Connection refused]]

解决方案

将startup.bat里添加的配置

set JAVA_OPTS=%JAVA_OPTS%-Dcom.sun.management.jmxremote.port="12345"  
set JAVA_OPTS=%JAVA_OPTS%-Dcom.sun.management.jmxremote.authenticate="false"
set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.ssl="false"

set JAVA_OPTS=%JAVA_OPTS%-Djava.rmi.server.hostname=XX.XX.XX.XX
set JAVA_OPTS=%JAVA_OPTS%-Dcom.sun.management.jmxremote.port="12345"  
set JAVA_OPTS=%JAVA_OPTS%-Dcom.sun.management.jmxremote.authenticate="false"
set JAVA_OPTS=%JAVA_OPTS% -Dcom.sun.management.jmxremote.ssl="false"
