Re: connection to db with pooling in Struts
You can use this little snippet to get a connection:
public Connection getConnection(String url, String driverClassName,
String
username, String password) throws SQLException {
try {
Class.forName(driverClassName);
} catch (ClassNotFoundException e) {
throw new SQLException(e.getMessage());
}
if (username == null) {
return DriverManager.getConnection(url);
}
return DriverManager.getConnection(url, username, password);
}
Personally I use hibernate with spring or guice to deal with all that
connection junk these days.

Hello guys,
I'm newbie about Struts and I'm trying to understand a complex task (for
me), that is obtaining a connection from connection pool (I use dbcp for
this) and a datasource (that one of tomcat) and use this connection in dao
layer.
I'm trying to get this working, but it seems very difficult to me.
Could you help me?
I show what I did:
-I added context in server.xml of tomcat
-I added declaration into web.xml of application, like this:
resource-ref
descriptionDB Connection/description
res-ref-namejdbc/TestDB/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
Now my first question.
What's next step? Could you please post simple code and comment to
understand?
What I imagine is now to have something to retrieve a connection and pass
it to dao.
Could you help me?
Thanks very much

Re: connection to db with pooling in Struts
That won't use the pool.
Take a look at some of the code snippets at [1]
