I have two questions.
1 .How is J2ME different from J2SE?
2. We used wml to develop WAP applications? In what ways is J2ME different?

1. I would suggest that you go thru the CLDC specifications from sun. In a nutshell , it is a subset of J2SE suited for devices with small memory and processing power.

2. In a WAP environment you get a thin client as the wap browser but if you use J2ME , you will be able to write thick client and stand alone applications.
One can also say ... the same difference between a swing application and a HTML/JSP/Servlet application

J2SE - This is a stadard edition of Java 2 Platform and comes with the full APIs and a large number of packages and used mainly for developing applications in java for computers and computer users.
See for more info : http://java.sun.com/j2se/1.4/
J2ME - This is the micro edition meant for the mobile and handheld devices. This is compact and provides small footprint at run time. The mobile or handhelds are limited in memory size comparing usual computers and a micro edition is required for developing java based applications for such devices.

WAP - Wireless application protocol is another protocol for wireless communication and its something similar to TCP/IP in networks. This protocol is heavily used to provide to bridge internet to the mobile and handheld devices. More information can be found at : http://www.wapforum.org/
