Hello
I am using vaadin with tomcat and with a jdbc datasource
I have got the following message in the tomcat logs when I stop tomcat:
the web application
[/myapplication] registered the JBDC driver [org.postgresql.Driver]
but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
how to/where can I unregister the jdbc driver?
I have the following code in my application class:
public static DataSource getDs() {
if (ds == null) {
Context ctx = null;
try {
ctx = (Context) new InitialContext().lookup("java:comp/env");
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
Dproject.ds = (DataSource) ctx.lookup("jdbc/dproject");
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return ds;
}
where to put my unregistering code? Which method/interface should I override/implement?
Peter
