Hello, When deploying an application using Websphere MQ, I get the following exception: Caused by: org.jboss.deployers.spi.DeploymentException: Error for ActivationSpec class com.ibm.mq.connector.inbound.ActivationSpecImpl as JavaBean | at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) | at org.jboss.resource.deployment.ActivationSpecFactory.createActivationSpec(ActivationSpecFactory.java:135) | at org.jboss.resource.deployers.RARDeployment.createActivationSpec(RARDeployment.java:313) | at org.jboss.resource.deployers.RARDeployment.internalInvoke(RARDeployment.java:276) | at org.jboss.system.ServiceDynamicMBeanSupport.invoke(ServiceDynamicMBeanSupport.java:156) | at org.jboss.mx.server.RawDynamicInvoker.invoke(RawDynamicInvoker.java:164) | at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:668) | at org.jboss.ejb.plugins.inflow.JBossMessageEndpointFactory.createActivationSpec(JBossMessageEndpointFactory.java:449) | ... 137 more | Caused by: java.beans.IntrospectionException: No property found for: acknowledgeMode on JavaBean: javax.jms.Queue:SYSTEM.DEFAULT.LOCAL.QUEUE@@localhost | at org.jboss.util.propertyeditor.PropertyEditors.mapJavaBeanProperties(PropertyEditors.java:354) | at org.jboss.util.propertyeditor.PropertyEditors.mapJavaBeanProperties(PropertyEditors.java:285) | at org.jboss.resource.deployment.ActivationSpecFactory.createActivationSpec(ActivationSpecFactory.java:129) I recently get out, that WMQ Resource Adapter doesn't support the property acknowledgeMode. How can I configure JBoss 5.1.0 that this exception is not thrown?
