This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
1 EJB Package
1 Web-Service Package
1 EAR Package which contains the above two packages
In the EAR, I see both the EJB Package and the Web-Service Package set under the Modules folder as a Services.war and a EJB.jar.
The Web-Service Package needs to access the EJB in my development environment so I goto the Properties window of the Web-Service Project and click on the Deployment Assembly option and add EJB.jar in the Manifest Entries tab. This would allow Eclipse to detect my EJB classes when I do import statements in the Web-Service classes.
However, I also found that I could do the same thing if I only add the EJB Project to the Projects tab of Java Build Path in the Properties for the Web-Service Project.
What exactly is the difference between these two ways and does it affect the behavior of the final EAR Package?
