get() method returns null if the object can’t be found. The load() method may return a proxy instead of a real persistent instance get() never returns a proxy.

There are no structural differences between the files; they are all archived using zip-jar compression. However, they are intended for different purposes.

*Jar files are intended to hold generic libraries of Java classes, resources, auxiliary files, etc.
*War files are intended to contain complete Web applications.
*Ear files are intended to contain complete enterprise applications.

Each type of file (.jar, .war, .ear) is processed uniquely by application servers, servlet containers, EJB containers, etc - See more at: http://inheritingjava.blogspot.in/2011/04/j2ee-interview-questions.html#sthash.BTqD58j2.dpuf
