A exceção é gerada quando tento fazer o Login no Sistema!

Talvez o erro seja tolo…
Já verifiquei todas as chamas dentro do meu código, entre eles arquivos de configurações e até o Context.xml do Tomcat 6.0

no context.xml

[code]

<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>

<Resource
name="jdbc/xxxxx"
Auth="Container"
type="javax.sql.DataSource"
username="root"
password="bluesat"
driverClassName="com.mysql.jdbc.Driver"                              
url="jdbc:mysql://127.0.0.1/xxxxxxx?autoReconnect=true"

maxIdle="5000"/>

[/code]

Aqui meu arquivo Config.properties

[code]
hibernate.connection.username = root
hibernate.connection.password = bluesat
hibernate.connection.url = jdbc:mysql://127.0.0.1/xxxxxx?autoReconnect=true
hibernate.connection.driver_class = com.mysql.jdbc.Driver

hibernate.dialect = org.hibernate.dialect.MySQLDialect

hibernate.connection.autoReconnect = true
hibernate.connection.autoReconnectForPools = true
hibernate.connection.is-connection-validation-required = true

hibernate.c3p0.min_size = 5
hibernate.c3p0.max_size = 300
hibernate.c3p0.timeout = 300
hibernate.c3p0.max_statements = 0
hibernate.c3p0.idle_test_period = 100
hibernate.maxAdministrativeTaskTime = 50[/code]

Ae pessoal, vocês tem algum norte dessa bronca ae?

Desde já agradeço a compreensão de todos.
