JSP Access to Session Bean
Can someone please confirm what is required to use a session Bean from a JSP, all deplayed on JBoss 3.2.5.
I'm continually getting
Error.javax.naming.NameNotFoundException: comp not bound
I've got the default jndi.properties file in conf in the classpath.
Also tried this method in the JSP:
public static Context getInitialContext() throws javax.naming.NamingException {
java.util.Properties p = new java.util.Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
p.put(Context.URL_PKG_PREFIXES, "jboss.naming:org.jnp.interfaces");
p.put(Context.PROVIDER_URL, "localhost:1099");
return new javax.naming.InitialContext(p);
}
Code segment in the JSP
try {
Context jndiContext = getInitialContext();
Object ref = jndiContext.lookup("java:comp/env/ejb/UnwyAppHome");
UnwyAppHome home = (UnwyAppHome)
PortableRemoteObject.narrow(ref,UnwyAppHome.class);
UnwyApp unwyApp = home.create();
Then added a jboss.xml although I thought it was optional.
jboss.xml
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE jboss PUBLIC "-//JBoss//DTD JBOSS 3.0//EN" "http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd">

<jndi-name>UnwyAppHome</jndi-name>
<ejb-name>UnwyBean</ejb-name>
<jndi-name>UnwyLocalHome</jndi-name>
</enterprise-beans>
ejb-jar.xml
