This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
The container is responsible for providing tools, which helps a Deployer to set or modify environment entry values.
is above statement is correct? environment entries are defined by bean provider in ejb-jar.xml file. Assembler can set or change environment entry values. But why container and deployer are coming in to picture. can a deployer change environment entry values?
Howdy -- a Deployer could definitely modify environment variables--in fact, we like to think of env variables as "deploy-time constants", because they are typically things that might vary from deployment to deployment (tax rates, discounts, etc.)
The Container just has to make sure that this is available for a deployer to modify. There is a good chance that the bean provider and possibly the app assembler do not *know* the real value until deploy-time.
