Find Number of VM message in Mule
- 1. Number Of VM Message We will find the number of VM Message using java component using Mule Context(Access using @Inject Annotation) Object by implementing Callable interface
- 2. Number Of VM Message - Flow • HTTP is used as in-bound connector • VM is used to store the message • Java component is used to find the number of message in VM • Object to String used to convert Object(Returned by Java) to String
- 3. Number Of VM Message - VM • Set Exchange Pattern as one-way • Queue path as “sunil” • Connector Configuration named as “VM” as <default-in-memory-queue-store/>
- 4. Number Of VM Message - Java
- 5. Number Of VM Message – Java Contd.. • Using “@Inject”(javax.inject.Inject) Annotation to get the MuleContext(org.mule.api.MuleContext) Object • Implements Callable (org.mule.api.lifecycle.Callable) Interface • Implemnts methos onCall to get access to MuleEventContext • Use MuleContext to get the size as “((VMConnector)muleContext.getRegistry().lookupCon nector("VM")).getQueueManager(). getQueueSession().getQueue("sunil").size()”
- 6. Number Of VM Message – Java Contd.. • Using “@Inject”(javax.inject.Inject) Annotation to get the MuleContext(org.mule.api.MuleContext) Object • Implements Callable (org.mule.api.lifecycle.Callable) Interface • Implemnts methos onCall to get access to MuleEventContext • Use MuleContext to get the size as “((VMConnector)muleContext.getRegistry().lookupCon nector("VM")).getQueueManager(). getQueueSession().getQueue("sunil").size()”
