where's the env here,
jndiContext = javax.naming.InitialContext(env) could help ;)

RE: [Jython-users] Jython / EJB question

[Don C. <don...@em...>]

I use jython to test EJBs.  I've found it is really easy to put the jndi
info in a jndi.properties files in the classpath.  This allows you to say
"context = InitialContext()" which is much easier to type in the
interpreter.  You can also modify the jython.bat and pass the information in
with -Dproperty=value.

# this code seem to work fine
# I'm using weblogic but I think I've used this with JBoss too
props = Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContectory");
props.put(Context.PROVIDER_URL,"t3://localhost:7001");
context = InitialContext(props);

object = jndiContext.lookup("BeanName")
beanHome = PortableRemoteObject.narrow(object, BeanHome.class)
bean = beanHome.create()

Re: [Jython-users] Jython / EJB question

[<la...@lu...>]

Arg. Actually, having the env in there doesn't help. This is what I get
for writing emails before I've had coffee :) The env is in the call in my
code

I still get the same error

jndiContext = javax.naming.InitialContext(env)
name = "interest/Interest"
jndiContext.lookup(name)

Here's the entire exception
