Development tools and environment: Windows XP, Tomcat 5.5.17, eclipse 3.2, myeclipse 5.0m2, MySQL 5.17 1. Create a web project; 2. Add spring capabinities and select the required packages. next, add the hibernate package. note that the order of addition is very important. 3. The following code is: Admin. java
