Greetings.
I'm having problems pulling a Referenceable (specifically, a DataSource)
from JNDI.
The code is pretty straight-forward:
System.out.println("Getting a context...");
InitialContext context = new InitialContext();
System.out.println("Getting a DataSource...");
Object obj = context.lookup("jdbc_1");
System.out.println("Got a " + obj.getClass().getName());
System.out.println("Narrowing...");
DataSource ds =
(DataSource)
PortableRemoteObject.narrow(
obj,
DataSource.class);
System.out.println("Getting a connection...");
con = ds.getConnection();
It looks like the lookup is pulling a javax.naming.Reference out of JNDI
instead of it being dereferenced back to a DataSource. The output is as
follows:
Getting a context...
Getting a DataSource...
Got a javax.naming.Reference
Narrowing...
java.lang.ClassCastException
at
com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemo
teObject.java:296)
at
javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)
at DataSourceTest.main(DataSourceTest.java:23)
Has anybody else come upon this and solved the problem? I'm thinking it's a
bug, possibly in org.objectweb.jonas.naming.CompNamingContext(.lookup())?
Looks like it's handling a LinkRef, but not the parent class Reference...
Thanks much in advance,
Thomas.
