I am writing code on top an established Enterprise application. I see that the application has 4 modules as shown below.
-Srk -SrkEJB -SrkUtils -SrkWeb
I have gone through the code and I see that some modules are tiny for example: SrkEJB module has got just 2 EJBS. I don't see any reason to create a separate module for 2 Java classes.
I have simplified the above approach and is shown below.
Srk - com.srk.utils - com.srk.ejb - com.srk.web
How is the first module based architecture different from the second from an architectural stand point? Generally, which is the followed mostly, when creating an application from scratch? If not, What could be the trade-offs of each of the approaches? I believe this is a not specific to Java alone.
