hello,
i've just started using jboss and tomcat. i have jboss and tomcat running
separately (no integration) and am attempting to access ejb's from a jsp.
i followed the instructions at jboss.org that told me to put the jboss
client files and my ejb interfaces into the WEB-INF/lib directory of my
webapp. however, when i do that, i get a ClassNotFound exception when
trying to load the org.jnp.interfaces.NamingContextFactory. if i put my
files in tomcat's main lib directory, then everything works fine. i don't
want to do this however for two reasons: (1) the docs said it should go in
WEB-INF/lib and (2) i can't pack up my app into a war if the classes have to
be in the global lib directory.
i've searched archives regarding this issue and from what i could tell, it's
a class loader problem?
anyone have any ideas what i'm doing wrong? thanks for the help in advance!
here is the list of file in my WEB-INF/lib:
11/14/2000 07:12p 7,958 ejb.jar
12/14/2000 03:23p 4,435 its.jar
11/14/2000 07:12p 71,549 jboss-client.jar
11/14/2000 07:12p 14,294 jnp-client.jar
11/14/2000 07:12p 8,809 jta-spec1_0_1.jar
12/15/2000 09:42a 23,348 kronos-ext.jar
12/15/2000 09:42a 7,371 kronos.jar
12/14/2000 02:36p 3,341 wondergeek.jar
here is my jsp code causing the error:
Hashtable env = new Hashtable();
env.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
env.put("java.naming.provider.url", "localhost:1099");
env.put("java.naming.factory.url.pkgs", "org.jboss.naming");
Context context = new InitialContext(env);
// i don't think i even ever get here...
Object ref = context.lookup("KronosServerBean");
KronosServerHome kh = (KronosServerHome)PortableRemoteObject.narrow(ref,
KronosServerHome.class);
KronosServer ks = kh.create();
and here is the stacktrace from tomcat:
