stop an application<\/p>\n

<jmx:invoke<\/p>\n

name=”Catalina:type=Manager,context=\/servlets-examples,host=localhost”<\/p>\n

operation=”stop”\/><\/p>\n

 <\/p>\n

Now you can find the sessionid at ${sessions.[0..N} properties and access the count with ${sessions.length} property.<\/p>\n

 <\/p>\n

Example to get all sessionids<\/p>\n

<jmx:invoke<\/p>\n

name=”Catalina:type=Manager,context=\/servlets-examples,host=localhost”<\/p>\n

operation=”listSessionIds”<\/p>\n

resultproperty=”sessions”<\/p>\n

delimiter=” ”<\/p>\n

\/><\/p>\n

Now you can find the sessionid at ${sessions.[0..N} properties and access the count with ${sessions.length} property.<\/p>\n

 <\/p>\n

Example to get remote MBean session attribute from session ${sessionid.0}<\/p>\n

<jmx:invoke<\/p>\n

name=”Catalina:type=Manager,context=\/ClusterTest,host=localhost”<\/p>\n

operation=”getSessionAttribute”<\/p>\n

resultproperty=”hello”><\/p>\n

<arg value=”${sessionid.0}”\/><\/p>\n

<arg value=”Hello” \/><\/p>\n

<\/jmx:invoke><\/p>\n

 <\/p>\n

Example to create a new access logger valve at vhost localhost<\/p>\n

<jmx:invoke<\/p>\n

name=”Catalina:type=MBeanFactory”<\/p>\n

operation=”createAccessLoggerValve”<\/p>\n

resultproperty=”accessLoggerObjectName”<\/p>\n

><\/p>\n

<arg value=”Catalina:type=Host,host=localhost”\/><\/p>\n

<\/jmx:invoke><\/p>\n

Now you can find new MBean with name stored at ${accessLoggerObjectName} property.<\/p>\n","protected":false},"excerpt":{"rendered":"
