I see a line in study guide in the
Overview chapter 1.
Could anybody explain me what does the below line say? If possible an example would help me to understatnd.
"The enterprise bean must not attempt to gain access to packages and classes that the usual rules of the Java programming language make unavailable to the enterprise bean"

This basically means that Bean Provider *must* *not* use Java Reflection API to get access to some variables or methods which are not accessible via regular Java calls.
For example, using Java Reflection, it is possible to get/set private variables from other classes. Doing this will break EJB Container contract which provides security, threading, pooling, etc.
