mysql> GRANT ALL PRIVILEGES ON *.* TO javauser@'10.13.106.%' IDENTIFIED BY 'javadude' WITH GRANT OPTION;
mysql> create database javatest;
mysql> use javatest;
mysql> create table testdata (id int not null auto_increment primary key,foo varchar(25),bar int);
mysql> insert into testdata values(null, 'ok', 12345);
mysql> flush privileges;

5、上传taglibs-standard-impl-1.2.5.jar、taglibs-standard-spec-1.2.5.jar和mysql-connector-java-5.1.10-bin.jar到/usr/local/tomcat/lib
6、重启tomcat
