no targets are reachable

[prasad kulkarni]

I have a adminserver and a managedserver. One ear is deployed on managedserver.

I updated the ear through admin console and started it, I got the error in log file as "no targets are reachable". When I checked the status of managedserver on admin console, it was - 'SHUTDOWN'; however the managedserver is up and running and also the ear-application is working fine on this server.
My redeployment is ineffective in this case . How can I solve this problem?
I know that if I restart both the servers, it will start working fine, however I am facing this problem many times and need a solution to this.

I tried to deploy the ear using admin console, which shows following stacktrace :

dumping Exception stack
Task 3 deferred: [Deployer:149026]distribute application DNAHits on ManagedServer.
Target state: distribute deferred on Server ManagedServer
java.rmi.RemoteException: [Deployer:149145]Unable to contact 'ManagedServer'. Deployment is deferred until 'ManagedServer' becomes available.
