JNDI lookup

[Poor Lee A More]

Do anyone have ideal how to get this JNDI lookup work in Jaxcent :
i can get the connection in my JSP but failed in Jaxcent java.

My code like this:
Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("jdbc/OracleDs");
Connection conn = ds.getConnection();

i had already defined the the jdbc/OracleDs in web.xml as:
<resource-ref>
<res-ref-name>jdbc/OracleDs</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

This is a J2EE thing - if you are using Jaxcent with a J2EE container,
e.g. Tomcat, it should automatically be available. But if you are
using the Jaxcent stand-alone server, it doesn't set up jndi
contexts. Maybe this will be a useful thing to add - does anybody
else have any comments on this?

yes. i'm using Jaxcent with J2EE.

i modified the JaxcentServlet to lookup my required DataSource, then put it in Application Context.

don't know whether it is a decent way.

public class JaxcentServlet extends HttpServlet implements jaxcentFramework.JaxcentHttpMain

{

    JaxcentFramework framework = new JaxcentFramework( this );

    DataSource ds = null;

    public void setDataSource() throws Exception {

        if ( ds == null ) {

                Context ctx = new InitialContext();

                ds = (DataSource) ctx.lookup("jdbc/OracleDs");

                getServletContext().setAttribute( "my.DataSource", ds );

        }

    }

    

    public void init()

          throws ServletException

    {

        framework.init();

        this.setDataSource();      // lookup DS ...

    }

Now I can get the datasource from the Application Context.

and finally get the connection....

        HttpSession session = (HttpSession) this.getHttpSession();

        ServletContext ctx2 = session.getServletContext();

        if ( ds == null ) {

            ds = (DataSource) ctx.getAttribute("my.DataSource");

            conn = ds.getConnection();

        }
