I'm trying to get dynamic loading of the interface classes using the
webserver to work also...
Ole, you say that classes in the EJB JAR are not served by the web server?
If this is true (I'll take your word for it), dynamic class loading is only
useful if one
adopts your approach and just put the interface jars in the class path.
Unfortunately, there's no way to add
a JAR to the classpath at runtime (as far as I know), so you would have to
bounce the server
or use a custom class loader.
Also, why is there no "sure way" to differentiate between interface classes
and implementation classes?
Seems to me that you could just check the type of classes in the JAR and
only serve those that are of
type EJBOjbect or EJBHome, which would only be the interface classes.
Am I missing something here?
regards,
Joe Barefoot

Hi,
Isn't it your EJB home interface that
cannot be found?
This is in your EJB jar, and its
classes are not served by the web
server.
This is similar to when one EJB jar
tries to access classes and defined
in another EJB jar.
Problem is, while it would make
sense to serve the interface classes
(but not implementation classes) of
the EJB jar, there are no sure way
to differentiate what classes are
interface and which are
implementation.
I seperate my EJBs in different jars
for implementation and interface.
EJB implementation jars go to deploy
directory, while interface jars go
in classpath.

Ole Husgaard.
