Hi Lubaki,
This is really weird: I have just done a couple of tests and I have not
been able to reproduce your problem. Basically, in an EJB I have this code:
XStream stream = new XStream();
stream.toXML("test");
In the OpenEJB DD, I have this:
<openejb-jar
xmlns="http://www.openejb.org/xml/ns/openejb-jar-2.0";
configId="clusteredSFSB"
parentId="ejbCluster"
inverseClassloading="true">
<dependency>
<groupId>xstream</groupId>
<type>jar</type>
<artifactId>xstream</artifactId>
<version>1.0.2</version>
</dependency>
<hidden-classes>
<filter>com.thoughtworks.xstream.XStream</filter>
</hidden-classes>
I call this EJB from an EJB client like this:
Properties p = new Properties();
p.put("java.naming.factory.initial",
"org.openejb.client.RemoteInitialContextFactory");
p.put("java.naming.provider.url", "127.0.0.1:4201");
p.put("java.naming.security.principal", "myuser");
p.put("java.naming.security.credentials", "mypass");
InitialContext ctx = new InitialContext(p);
BasicStatefulHome home = (BasicStatefulHome)
ctx.lookup("client/clustertest/BasicStatefulHome");
BasicStatefulObject object = home.create();
object.setState("my state");
The CL of Xtream is the CL of the EJB module. I have remove the
<dependency> from the OpenEJB DD, a ClassNotFoundError is thrown as
expected.
Also, note that as inverseClassloading is set to "true", classloading is
inversed. As a consequence, you do not really need to define a
hidden-classes element.
Could you please send me a EJB reproducing this problem such that I can
backtrack it?
Thanks,
Gianny

Gianny,
Using Geronimo 1.0, I am still having the same issue. Here an example
of the config file. It (Geronimo Classloader) did not filter XStream.
Similarly with axis..........
