Can you upload your entire EAR? In the meantime, you can workaround this by editing the %JBOSS_HOMR%/server/< servername>/conf/bootstrap/deployers.xml to comment out the following: <bean name="Deployers" class="org.jboss.deployers.plugins.deployers.DeployersImpl"> | <!-- Comment this out | <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.deployment:service=DeployersImpl", exposedInterface=org.jboss.deployers.plugins.deployers.DeployersImplMBean.class, registerDirectly=true)</annotation> | | --> | <constructor><parameter><inject bean="jboss.kernel:service=KernelController"/></parameter></constructor> | <!-- Accept any implementor of deployer --> | <incallback method="addDeployer"/> | <uncallback method="removeDeployer"/> | <property name="mgtObjectCreator"><inject bean="ManagedObjectCreator"/></property> | </bean> | This workaround will not have any adverse effect.
