[Springframework-developer] sample jpetstore exception on connect to mysql

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

I configure war/WEB-INF/jdbc.properties  as below:

jdbc.driverClassName=org.gjt.mm.mysql.Driver 
jdbc.url=jdbc:mysql://localhost:3306/petclinic 

and modify the build.xml in order to embrace the mysql connect file:
mysql-connector-java-3.1.1-alpha-bin.jar

after ant all, I looked that the mysql-connector-java-3.1.1-alpha-
bin.jar file is in the jpetstore.war, then I put the jpetstore.war to 
$TOMCAT_HOME/webapps directory, I type the 
http://localhost:8080/jpetstore in browser the index file displayed 
well, but when it access database it has the exception as below:

org.springframework.jdbc.CannotGetJdbcConnectionException: Could not 
get JDBC connection; nested exception is 
org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver 
class 'org.gjt.mm.mysql.Driver ' 
org.apache.commons.dbcp.SQLNestedException: Cannot load JDBC driver 
class 'org.gjt.mm.mysql.Driver ', cause: 
java.lang.ClassNotFoundException: org/gjt/mm/mysql/Driver 
at java.lang.Class.forName0(Native Method 

how can I should do ? why it could not find the Class: 
org/gjt/mm/mysql/Driver

I list the file mysql-connector-java-3.1.1-alpha-bin.jar below:
