Error in MDB

[rajashree loganayagi]

Hi,

I wrote a program using Message Driven Beans(MDB). It throws an error like this in Jboss:

--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:service=EJB,plugin=invoker,binding=message-inflow-driven-bean,jndiName=local/AMLWSMDBJRemote@32331490
State: FAILED
Reason: org.jboss.deployment.DeploymentException: Cannot locate resource adapter deployment null; - nested throwable: (javax.management.InstanceNotFoundException: jboss.jca:service=RARDeployment,name='null' is not registered.)
--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: jboss.j2ee:service=EJB,plugin=invoker,binding=message-inflow-driven-bean,jndiName=local/AMLWSMDBJRemote@32331490
State: FAILED
Reason: org.jboss.deployment.DeploymentException: Cannot locate resource adapter deployment null; - nested throwable: (javax.management.InstanceNotFoundException: jboss.jca:service=RARDeployment,name='null' is not registered.)

Can anyone help me to solve this error....

Thanks in advance.....
