Tomcat Struts Datasource problem

hello! I develop a Struts application and I have a problem with
starting my Tomcat. I sought why and I know that the problem is of Data
Source. But I did not find a solution.

Here my declaration of Data Source in Sruts-config.xml :

<data-sources> <data-source
type="org.apache.commons.dbcp.BasicDataSource"> <set-property
property="driverClassName" value="com.mysql.jdbc.Driver" />
<set-property property="url" value="jdbc:mysql://localhost/bddStruts"
/> <set-property property="username" value="root" /> <set-property
property="password" value="struts" /> <set-property
property="maxActive" value="12" /> <set-property property="maxWait"
value="5000" /> <set-property property="defaultAutoCommit" value="true"
/> <set-property property="defaultReadOnly" value="false" />
<set-property property="validationQuery" value="SELECT COUNT(*) FROM
users" /> </data-source> </data-sources>

I use NetBeans, and I have this error in the console:

GRAVE: Initializing application data source
org.apache.struts.action.DATA_SOURCE

org.apache.commons.dbcp.SQLNestedException: Cannot create
PoolableConnectionFactory (Communication link failure:
java.io.IOException, underlying cause: Unexpected end of input stream

If somebody could help me it would be very nice.

I have been blocked for one week.

I cannot any more what make.

Thank you for your help.

Ps: Sorry for the expression, I am French.
