I don't see an elegant way around unless we
1- say don't put the classes in web-inf, thereby going against the spec
2- generalize the use of scoped class loaders (jung) in jetty to bypass
marcf

|Subject: [JBoss-dev] Optimized EJB calls in catalina
|
|
|I looked at integrating the catalina final release with integrated
|security and JNDI and I find that everything works except for optimized
|EJB calls. This occurs for wars that include the EJB interfaces in their
|classes directory. This has been required for wars with JSP pages that
|access EJBs. I have not tested the catalina version of jasper to see if
|this is still required.
|
|The reason EJB calls are not optimized for this scenario is that the
|web container class loader loads classes in WEB-INF/classes before
|asking its parent class loader. This seems to be consistent with the
|2.3 servlet spec if "container-wide library JARs" is taken to mean
|jars accessible by the container parent class loaders.
|
|If the EJB interfaces are not in the war then call optimization works as
|before.
|
|<servlet-2.3-fcs spec>
|SRV.9.7.2 Web Application Classloader
|
|The classloader that a container uses to load a servlet in a WAR must allow
|the
|
|developer to load any resources contained in library JARs within the WAR
|
|following normal J2SE semantics using getResource. It must not allow theWAR
|to
|
|override J2SE or Java servlet API classes. It is further recommended that
|the loader
|
|not allow servlets in theWAR access to the web container's implementation
|classes.
|
|It is recommended also that the application class loader be implemented so
|
|that classes and resources packaged within the WAR are loaded in preference
|to
|
|classes and resources residing in container-wide library JARs.
