Hi!

I am a new user of Spring Framework and I have an error that I don't understand. When the builder try to parse the file spring-config-test-dao-mysql.xml I have these errors:

For informations I show you the file spring-config-test-dao-mysql.xml :

<?xml version="1.0" encoding="ISO_8859-1"?>
<!DOCTYPE beans SYSTEM "http://www.springframework.org/dtd/spring-beans.dtd">

</beans>

I have followed the tutorial of Serge Tahe and I think I included all necessary library in the classpath:
commons-pool.jar
commons-dbcp.jar
ibatis-common-2.jar
ibatis-sqlmap-2.jar
spring-*.jar
xerces.jar
etc...

I hope that you could help me !
thanks
