Struts 1 and connection-pooling

I've succeeded in using connection-pooling in my web app (which doesn't use the Struts framework). Now I need to integrate a part written by another developer (part that uses the Struts 1 framework). The problem is that I don't succeed in using the pool with Struts 1.

Should it possible?

In my Tomcat context.xml, I have:

    <Resource name="jdbc/MyDB" auth="Container" type="javax.sql.DataSource"
          maxActive="100" maxIdle="30" maxWait="10000"
          username="auser" password="apwd" driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/mydb" 
          factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" />

The other developer is using connections from servlet execute like:

 Class.forName("com.mysql.jdbc.Driver");
 con = (Connection) DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb", "auser", "apwd");

Use code something like this in servlet

// Obtain our environment naming context
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");

// Look up our data source
DataSource ds = (DataSource)
  envCtx.lookup("jdbc/MyDB");

// Allocate and use a connection from the pool
Connection conn = ds.getConnection();
... use this connection to access the database ...
conn.close();
