[jboss-user] [Management, JMX/JBoss] - Re: Parameter names in Mbeans

Yes there is - Spring to the rescue!  Here is an example:

In you MBean, decorate your method with annotations like this:


  |     @ManagedOperation(description = "Create a job")
  |     @ManagedOperationParameters({
  |         @ManagedOperationParameter(name = "accountName", description = "The name of the account to create the Job in."),
  |         @ManagedOperationParameter(name = "applicationName", description = "The name of the application to create the Job in."),
  |         @ManagedOperationParameter(name = "jobName", description = "The name of the Job to create."),
  |         @ManagedOperationParameter(name = "lineItems", description = "input line items for the job.  Fields are comma-separated.  Lines are linefeed separated")
  |             })
  |     public String createJob(String accountName, String applicationName, String jobName, String lineItems) throws Exception
  | {
  |     // MBean code here
  | }
  | 

then declare MBean support in Spring like this:



  |     <!--  ###################################################    -->
  |     <!--  ####                                           ####    -->
  |     <!--  ####          MBEAN EXPORT CONTROL             ####    -->
  |     <!--  ####                                           ####    -->
  |     <!--  ###################################################    -->
  | 
  |     <!-- the adapter to expose various Beans as MBeans.  MBeans are auto-detected in the declared beans through annotations -->
  |     <bean id="mbeanExporter" class="org.springframework.jmx.export.MBeanExporter">
  |         <property name="assembler" ref="assembler"/>
  |         <property name="autodetectModeName" value="AUTODETECT_ASSEMBLER"/>
  |         <property name="namingStrategy" ref="namingStrategy"/>
  |     </bean>
  | 
  |     <!-- declare that Java 5 annotations will be used to derive MBean meta-data -->
  |     <bean id="assembler" class="org.springframework.jmx.export.assembler.MetadataMBeanInfoAssembler">
  |         <property name="attributeSource" ref="attributeSource"/>
  |     </bean>
  | 
  |     <!-- declare that Java 5 annotations will be used for MDB naming -->
  |     <bean id="namingStrategy" class="org.springframework.jmx.export.naming.MetadataNamingStrategy">
  |         <property name="attributeSource" ref="attributeSource"/>
  |     </bean>
  | 
  |     <!-- declare that Java 5 annotations will be used to derive MBean attributes -->
  |     <bean id="attributeSource" class="org.springframework.jmx.export.annotation.AnnotationJmxAttributeSource"/>
  | 
  | 

Then declare your MBean as a managed resource:


  | @ManagedResource(description = "Job Creation operations", objectName = "blah.operations:name=jobCreation")
  | public class JobCreationMBean
  | 

and create one in Spring:


  |     <!-- an MBean to expose the job creation/upload functionality -->
  |     <bean id="jobCreation" class="com.blah.misc.servlet.JobCreationMBean">
  |         <!-- bean configuration here -->
  |     </bean>
  |
