Question

I have an EJB Project with a @Singleton EJB defined as:

@LocalBean
@Singleton 
@Startup
public class DataModelBean implements DataModelBeanLocal {

I then have another EJB Project with another EJB:

@LocalBean
@Singleton
@Startup 
@EJB(beanInterface=DataModelBeanLocal.class,name="DataModelBeanLocal")
@DependsOn("DataModelBeanLocal")
public class OutboundRouting implements OutboundRoutingLocal {

However the @DependsOn is not working, I have tried a number of different values for the @DependsOn with no success. The server fails to start with:

Deployment Error for module: Atlas: Exception while deploying the app : java.lang.RuntimeException: Invalid DependsOn dependency DataModelBeanLocal for EJB OutboundRouting%%%EOL%%%

I am not sure what I should be doing here, any suggestions?

Answer 1

Try this instead:

@Singleton
@DependsOn("DataModelBean")
public class OutboundRouting { ... }

Answer 2

Define a Singleton with a name

@Singleton(name = "DataModelBeanLocal ")
@Startup
public class DataModelBean implements DataModelBeanLocal {

in your secound singleton you can now define the dependencies

@Singleton
@Startup 
@DependsOn("DataModelBeanLocal")
public class OutboundRouting implements OutboundRoutingLocal {

In our Projekt it works fine
