Question

I have a web app deployed with Tomcat Server and i have an exception.

Name jdbc/_UserRight is not related to Context

and this is my context :

<Resource name="jdbc/_UserRight" auth="Container"
    type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000"
    username="XXXXX" password="XXXXX" driverClassName="com.mysql.jdbc.Driver"
    url="jdbc:mysql://localhost:3306/userright" />

And this is my connection class:

public class ConnectionUserRight {
private Connection cnx;
private ConnectionPool connectionPool;

public ConnectionUserRight() throws ConfigFileReaderException, IOException,
        SQLException {
    connectionPool = new ConnectionPool();
}

public Connection getCnx() throws SQLException, NamingException {
    if (null == this.cnx) {
        this.cnx = connectionPool.getConnection("jdbc/_UserRight");
    } else {
        // Connexion already open
    }

    return cnx;
}

public void closeCnx() {
    connectionPool.closeConnection(this.cnx);
    this.cnx = null;
}
}

EDIT:

This is my log (the first line exception is in french):

Answer 1

It looks like your connectionPool is just being created without a context. Try something like –

Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
this.cnx = (DataSource) envCtx.lookup("jdbc/_UserRight").getConnection();
