the ejb3.0 specification says (chapter 60 page 241):
There is also an example on page 242:
Now finally my questions are:
1. Why did we need to include the ejb1_client.jar in app2.ear (or even in app1.ear), wasn't it enough to refer to it (using class-path in Manifest, or may be just by using <ejb-client-jar>) as the bullets quoted first suggest?
2. How come we didn't need to use <ejb-client-jar> for ejb2.jar
3. Since both of ejb1.jar and ejb2.jar are packaged in app1.ear couldn't we simply refer to the ejb1_client.jar in the Manifest file of app1.ear?
