Hi
I am sure this is a common issue but I looked it up on google and nobody
seem to have a real good fix about this. Or maybe there is something I don't
understand something... ? here is my problem:
I try to use the glassfish appserv-rt.jar client library to enable my webapp
to call EJBs remotely in my tomcat 6 context.
With a simple test application. I can successfully call an EJB from a
servlet.
I place my jars (javaee.jar and appserver-rt and the necessary dependencies)
in my WEB-INF/lib/ direcectory. I build the InitialContext by hand and set
the properties that will serve to initialise the jndi jndi name resolver.
This is my base app I used test that everything is working.
In another app. With more complex libraries (ex: Seam, richfaces, etc). I
have a classloading issue. If I put the appserver-rt.jar and javaee.jar in
my web-app /WEB-INF/lib directory the web-app won't deploy because the
classloading is not done in the right order so when it's some on my seam
componenent instantiate and I try to fill some cache from the EJBs, the call
fails because the appserver-rt-jar as not yet been loader (or I guess, is
not loaded by the class loader because of the javax.* java.* constraint of
the servlet specification?)
I tried to move things arround... and put the appserver-rt.jar in
CATALINA_BASE/lib forlder
If I put the javaee.jar in CATALINA_BASE/lib/ there is no problem.
If I put the appserver-rt file into the CATALINA_BASE/lib/ folder the server
does not start because of a NamingException. I am not sure I understand why
there seems to be a problem/conlict between the ressourcefactory in the
appserver-rt.jar and tomcat's resourcefactory. Anyone know how to get
arround this problem in a clean way? I am seen solutions like renaming the
appserver-rt.jar to zappserver-rt.jar so it is loader last... but this is
not a clean solution.
Here is the output of my tomcat server when I start it with the
appserver-rt.jar in the CATALINA_BASE/LIB foder:
