Hi, list.

I'm using Tapestry 5.0.15.

I wrote a bit of code:

String driver = "org.postgresql.Driver";
String url = "jdbc:postgresql://localhost/sample";
String username = "hoge";
String password = "hogo";

Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, driver);

Context context = new InitialContext(properties);
DataSource ds = (DataSource)context.lookup(url);
Connection con = ds.getConnection(username, password);

in my service class, and got an exception:

javax.naming.NoInitialContextException: Cannot instantiate class:
org.postgresql.Driver [Root exception is java.lang.ClassCastException:
org.postgresql.Driver]

How do I let it work to?


On struts & Tomcat, we can use META-INF/context.xml
and just write:

Context ctx = new InitialContext();
DataSource ds = (DataSource)ctx.lookup("java:comp/env/jdbc/sample");

How do I write on Tapestry? (or Jetty???)

Thanks.

Ken.
