Exception at Handle deserialization

Question

Hello all,
I have a problem with deserialization of a previously serialized bean's handle.
What I do:
1. In one java virtual machine I have a piece of code that do the serialization of my bean's handle - something like this:
MyBean session = ......
Handle handle = session.getHandle();
ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(new File("./handle.dat")));
oos.writeObject(handle);
oos.close();
2. In the second JVM I do something like this:
ObjectInputStream oois = new ObjectInputStream(new FileInputStream(new File("./handle.dat")));
Handle handle = (Handle)oois.readObject();
oois.close();
EJBObject bean = handle.getEJBObject();
The second JVM runs a very simple client. The JVM has on its classpath weblogic.jar and all needed jars.
When I run the second JVM I get the following while performing oois.readObject() :
java.lang.ExceptionInInitializerError
     at weblogic.ejb20.internal.HandleImpl.readExternal(HandleImpl.java:99)
     at java.io.ObjectInputStream.readExternalData(ObjectInputStream.java:1686)
     at java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1644)
     at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1274)
     at java.io.ObjectInputStream.readObject(ObjectInputStream.java:324)
     at com.markocki.server.impl.ClassReader.main(ClassReader.java:31)
Caused by: java.lang.NullPointerException
     at weblogic.rmi.utils.io.RemoteObjectReplacer.<clinit>(RemoteObjectReplacer.java:47)
     ... 6 more
The question is: what I do wrong? Should I do anything extra in the second JVM (prepare it in someway to be capable to deserialize the handle) ?
Ps. Serialization to a file is an example here, I get the same error when I use RMI for passing the handle.

Bart

Sorry I forgot to mention that I use Weblogic Server 8.1 SP 3.
