After the first deployment the only thing i can see is: 15:25:59,586 INFO [Server] JBoss (MX MicroKernel) [4.2.1.GA (build: SVNTag=JBoss_4_2_1_GA date=200707131605)] Started in 44s:984ms 15:30:00,322 INFO [EjbModule] Deploying BankAccount 15:30:00,443 INFO [EjbModule] Deploying BruttoNettoBean Nothing further, even on redeployment. I cant find an "[EJBDeployer] deployed" in my server.log . Only the logs I posted in my message before. I get the impression, that something in the logging engine crashes. It must have to do with my archive, otherwise this would not happen on other jboss versions... But what causes the log engine to crash and doesnt affect the functionality of the ejbs?
