I would very much appreciate any info you can give to get ejb 1.1 cmp to
work with Interbase (for that matter any database).
As it turns out, I seem to not beable to get an EJB to see another EJB.
Whether its session or entity. I can get one EJB from my servlet, thats no
problem. But in that EJB code I try to get the InitialContext and what not
to find another EJB to call upon it, and I keep getting NamingException, or
sometimes RemoteException (depending on what I am tampering with to get it
to work).
I believe it stems to the jndi properties. In my EJB, I simply do:
Context context = new InitialContext();
context.lookup("java:comp/env/ejb/SecondEJBName");
That seems to throw the naming exception. I do have the ejb-ref tag in the
first ejb with the /ejb/SecondEJBName name. However, I looked at some demos
in the Orion examples, and they all have a jndi.properties file, and I also
read in my EJB book that EVERY vendor has a different way of finding the
context or something. I couldn't quite figure out why this would be since
supposedly EJB 1.1 is a standard and you should be able to move your code to
an J2EE app server. I didn't think there would be any problems like this. So
I guess what I am trying to figure out is if in my EJB I need to provide
these properties every time I look up another EJB or not.
Also, when I run Orion with the console, it appears that the java:comp
folder shows up, and there is an ENV folder below it, but my ejb doesn't
show up in an EJB folder below ENV. Instead I see at the java: level a
"com.company.package.EjbName" context..as if its a separate context..and not
below the java:comp one. This is confusing to me..I would expect the name of
my ejb to show up under the env folder, under an ejb folder, with just the
name of the ejb there. Am I doing something wrong..can you see your EJBs in
the console in a tree below comp/env/ejb? I sure don't.
Thanks.
