In an attempt to obtain a reference to the Administrator
inside Orion, i have written the following code in my client.
<snip>
Hashtable orionProps = new Hashtable();
orionProps.put(Context.INITIAL_CONTEXT_FACTORY,
"com.evermind.server.ApplicationClientInitialContextFactory");
orionProps.put(Context.PROVIDER_URL, "ormi://localhost");
orionProps.put(Context.SECURITY_PRINCIPAL, "admin");
orionProps.put(Context.SECURITY_CREDENTIALS, "123");
Context orionInitialContext = new InitialContext(orionProps);
Object obj= orionInitialContext.lookup("java:comp/Administrator");
<------ !!EXCEPTION HERE!!
ApplicationAdministrator admin =
(ApplicationAdministrator)javax.rmi.PortableRemoteObject.narrow(obj,Ap
plicationAdministrator.class);
<snip>
Additionally, in my META-INF directory there are two
XML files:
1) application-client.xml , containing:
<?xml version="1.0"?>
<!DOCTYPE application-client PUBLIC "-//Sun Microsystems, Inc.//DTD
J2EE Application Client 1.2//EN"
"http://java.sun.com/j2ee/dtds/application-client_1_2.dtd">
<application-client>
<display-name>OrionHealthClient</display-name>
</application-client>
2) orion-application-client.xml, containing:
<?xml version="1.0"?>
<!DOCTYPE orion-application-client PUBLIC "-//Evermind//DTD J2EE
Application-client runtime 1.2//EN"
"http://www.orionserver.com/dtds/orion-application-client.dtd">
<orion-application-client>
</orion-application-client>
However, when i attempt to lookup the Administrator in the line
marked above,
i receive the following exception:
javax.naming.CommunicationException: Can't find SerialContextProvider

Could someone please point out my mistake.
