jre = java runtime environment. it's basically what is needed to run java programs.
j2ee and j2se are different versions of the jdk (java development kit). in j2se, s = standard, meaning it has the standard libraries. in j2ee, e = enterprise, means more fancy stuff that i've never used before

The Java platform (Enterprise Edition) differs from the Java Standard Edition Platform (Java SE) in that it adds libraries which provide functionality to deploy fault-tolerant, distributed, multi-tier Java software, based largely on modular components running on an application server.

Adding a bit more, J2EE(Java2 Enterprise Edition) is for developing component-based multitask applications, with web based stuff. J2SE(Java2 Standard Edition) provides the complete environment for application developments on servers and desktop. And also J2EE is built on the J2SE and J2EE has the larger API.
