Database Pooling in Struts

I'm following the tutorial from the book "Jakarta Struts Live� and I have problems connecting to my database (Struts 1.1):

This is the code inside the Action class:
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {

UserRegistrationForm userForm = (UserRegistrationForm) form;
DataSource dataSource = getDataSource(request, "userDB"); // *** ERROR: GETS A NULL ***
Connection conn = dataSource.getConnection();
The data-sources in struts-config.xml:
<data-source type="org.apache.commons.dbcp.BasicDataSource" key="userDB">
<set-property property="driverClassName" value="sun.jdbc.odbc.JdbcOdbcDriver" />
<set-property property="url" value="jdbc dbc atosStruts" />
<set-property property="username" value="jose" />
<set-property property="password" value="jose" />
The init-param in web.xml:

The problem seems to be that the code in the Action class (above)

DataSource dataSource = getDataSource(request, "userDB");

returns a null.

I've debugged the application and I've realized that, inside the Struts getDataSource method, the ServletContext doesn't contain the "userDB" attribute.

Any help?

Never mind, everything was correct. It was my IDE which deleted the <data-source>.
I agree. Here's the link: http://aspose.com/file-tools
