Right now your configuration loads the same jar into each of the web
app classloaders, so the classes are different (same bytes, different
classloaders). You need to get the common jar into a shared
classloader. Some ways to do this are:
1. create a configuration with (only) that common jar as a
dependency, and have a dependency on this configuration in both web apps
2. make one web app depend on the other one
3. use the shared-lib feature (I don't recommend this)

Hello,
I try to put a Javaobjekt to the global JNDI Context, and access
this Objekt from different Applications.
A WebApplication (named webAppA) deployed as standalone WAR File,
puts an Object to the global JNDI Context:
InitialContext ic = new InitialContext();
Context namingContext = (Context) ic.lookup("ger:");
RolleDTO objectToBind = new RolleDTO();
namingContext.bind( "myObject" , objectToBind);
Another WebApplication (named webAppB) deployed as WAR File inside
an EAR File, trys to access the Object with name myObject:
InitialContext ic = new InitialContext();
Context context = (Context) ic.lookup("ger:");
RolleDTO rolle = (RolleDTO) context.lookup("myObject ");
The Result is the follwoing ClassCastException.
Both Webapplications uses a common lib, which contains the RolleDTO
class, and both has a dependency entry in geronimo-web.xml to this
Library. This lib only exists as common lib. No local versions are
placed inside the war files or inside the ear file.
I’m using Geronimo 2.0.1. Has anyone an idea what is going wrong?
Thanks a lot
Jochen
