Serialization/Deserialization

[John Brecht]

I have created an Object that implements Serializable.  My client seems to be able to write it to an ObjectOutputStream, but when the Servlet tries to deserialize it, it gives the error:

 

[08/04/1999 14:19:14:440 EDT] java.io.InvalidClassException: edu.msu.lite.JHomework.AttemptRequest; is not Serializable
 at java.io.ObjectStreamClass.verifyInstanceDeserialization(ObjectStreamClass.java:1042)
 at java.io.ObjectInputStream.inputObject(Compiled Code)
 at java.io.ObjectInputStream.readObject(ObjectInputStream.java:369)
 at java.io.ObjectInputStream.readObject(ObjectInputStream.java:232)
 at edu.msu.lite.JHomework.Dispatcher.doPost(Dispatcher.java:45)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:521)
 at javax.servlet.http.HttpServlet.service(HttpServlet.java:588)
 at org.apache.jserv.JServConnection.run(JServConnection.java:359)
 at java.lang.Thread.run(Thread.java:479)

 

The Object AttemptRequest is the Object that SHOULD be Serializable, at least it "implements Serializable".  Dispatcher is the name of my servlet Class.  The same class file for AttemptRequest is in the client directory and in the servlet directory.  I can't debug within the servlet to get more info because I can't make logging work.  Has anyone run into similar trouble with deserialization?
