Hi, I've had the same problem, but deploying two EJB3 SLSB into a .sar containing an MBean (a custom service). Into the .sar archive, along with the code of the service MBean, I have an .ejb3 archive containing the two SLSB; one of this SLSB has a dependency on the MBean (with @Depends annotation). When I deploy the .sar copying it under deploy/ directory on a running instance of JBoss, the deploy has success; the problem arises when I restart the instance with the .sar always on the deploy/ directory. The exception is thrown for each one of the SLSB. My configuration is: JBoss 4.0.5.GA (with EJB3 patches) JDK 1.5.0_12 Any help is very appreciated. Thanks!
