Hi All,

I use Weblogic 8 , Win 2000 , Struts , EJB ( Bean Managed persistence- BMP ), design patterns like DAOs(Data Access Objects) and Data Transfer Objects/Value Objects ( DTOs/ VOs). IDE is Eclipse.

Now I have three Projects in the App.

1. NEA -> It's got JSPs , Struts Classes.
2. NEA_EJB -> Entity Beans with BMP + DAOs
3. NEA_DTO -> seperate project containng DTOs which is being used by NEA_EJB.

Is it a professional attitude to put DAOs and EJBs together in one JAR file ???

Thanks
-Anand.

Anand,
Yes, it is fine to put the DAOs and EJBs in the same project. Both are in the data transfer layer. It would be even better to put them behind a stateless session bean. That abstracts the client from even knowing what technology you are using for db access.
