Question about classloader in ear package

xin.zhang.song Dec 13, 2012 5:17 AM

Hi Guys

I met a question about the classloader in ear package:

I have a ear package: the ear package structure look like this:

myapp.ear

|

|--- ejb1.jar

|

|--- ejb_util.jar

|

|--- ejb2.jar

The ejb in ejb2.jar refers to a class in ejb_util.jar, but the class has been load by class in ejb1.jar.

and it induce that classcast exception.

I have no idea for this, Is there some advice for this?

Thanks

Xin

Is the result the same if you put the ejb_util.jar in the lib folder of the ear?

I would also suggest moving the util jar to EAR/lib, and do not declare any class-path dependency to the util jar from ejb1 or ejb2.
