Dear all experts,

I have 2 program:
- ClientApp.java is a client side Java application
- ServletApp.java is a Java servlet running in Tomcat 3.2.3

When I try to open a URLConnection from ClientApp to request an object
create by the servlet, it is OK and no problem (see my remarked code in 
both program).  

But when I try to switch their job, ClientApp send an object to
ServletApp.  The exception "Socket Exception: JVM_recv in socket input
stream read" occurs in the servlet side, and it seems that the servlet was
hasn't been called, because there is no "Hello" message in my console.  It
looks where strange, because when I receive an object from the servlet
side.. there was no problem at all.

Do you guys have any clues on it ?  I am running the serlvet on Tomcat 
3.2.3.

Thanks a lot !
