Hi,
I am a junior programmer. I attended an interview recently. Some of the ejb questions i couldn't answer well. I think i should have answered them as they are not real tough. Here are the qtns:
1.Can you describe all the steps involved in ejb deployment on weblogic?
my answer was:
-compile remote,home interfaces , bean class and JAR them. Then use weblogic deployer to deploy jar file.
Then he asked
2.what is the role of .ear and .war files and when they are created
3.what will happen if two session beans with transaction attribute as serializable, access an entity bean?
Even though i didn't answer them, I want to know the answers so that i wont commit mistake next time. Please help me with answers. thank you.
