I am not sure about the usage

The EJB3.1 spec, section 4.8.1 has the details.

but i could not use it like this( @Singleton(DependsOn="SomeSingletonBean") i get compilation error 

That's not how it's supposed to be used. The correct way is:

 

@Singleton
@DependsOn("OtherSingletonBeanName")
public class SingletonOne
{
.....

I assume that the code is just a pseudo code since it's not going to compile. What does the SingletonProcessBean2 look like? Please post the real code of both SingletonProcessBean1 and SingletonProcessBean2. Also please post the console logs that you see when you start deploying your application.
