Remote ejbs and weblogic cluster

 Hello.I ran into the following scenario a few days back. We hotdeployed an ear in production which is a cluster of three modes on different machines. The old application was deleted before the new application was deployed. In the console the new deployment was marked as active. But other applications couldn't do a jndi lookup to the new application. After checking on the application it was only active on one of the nodes in production. The other two had failed and those two were failing the jndi lookup. So my question is shouldn't the jndi lookup always succeed if any
