| attribute | Existing MBean attribute (see Tomcat MBean description above) | |
| ref | JMX Connection reference | jmx.server |
| echo | Echo command usage (access and result) | false |
| resultproperty | Save result at this project property | |
| delimiter | Split result with delimiter (java.util.StringTokenizier) and use resultproperty as prefix to store tokens. | |
| separatearrayresults | When return value is an array, save result as property list ($resultproperty.[0..N] and $resultproperty.length) | true |
Example to get remote MBean attribute from default JMX connection
<jmx:get
name=”Catalina:type=Manager,context=/servlets-examples,host=localhost”
attribute=”maxActiveSessions”
resultproperty=”servlets-examples.maxActiveSessions”
/>
Example to get and result array and split it at separate properties
<jmx:get
name=”Catalina:type=ClusterSender,host=localhost”
attribute=”senderObjectNames”
resultproperty=”senderObjectNames”
/>
Access the senderObjectNames properties with:
${senderObjectNames.length} give the number of returned sender list.
${senderObjectNames.[0..N]} found all sender object names
Example to get IDataSender attribute connected only when cluster is configured.
Note: The name attribute value was wrapped here to be more readable. It has to be all on the same line, without spaces.
<jmx:query
failonerror=”false”
name=”Catalina:type=Cluster,host=${tomcat.application.host}”
resultproperty=”cluster”
/>
<jmx:get
name=
“Catalina:type=IDataSender,host=${tomcat.application.host},
senderAddress=${cluster.backup.address},senderPort=${cluster.backup.port}”
attribute=”connected”
resultproperty=”datasender.connected”
if=”cluster.0.name” />
