Hi,
I ran into the following problem:
I have a servlet that reads serialized java objects from a POST request
called TunnelServlet which is in the global classpath of the server because
it's a general purpose utility. in addition to that I have a servlet
DomainAdminTunelServlet in a deployment jar file that extends TunnelServlet
that uses its serialization capabilities. the classes of the serialized
objects are known to the DomainAdminTunnelServlet because they are in the
same deployment jar file. however the readObject call in TunnelServlet
fails with a ClassNotFoundException (Stacktrace below) if I don't put the
classes of the serialized objects into the global server classpath which is
definitely something I don't want to do. Am I doing something wrong here or
should this work? The strange thing is that writeObject calls to the
servlet's response output stream work OK.
The setup in short again:
TunnelServlet (loaded via server classpath) delegates calls to extending
classes via reflection
DomainAdminTunnelServlet extends TunnelServlet (loaded via deployed jar file)
UnitData (implements Serializable and is read from servlet input stream,
loaded via the same jar file as DomainAdminTunnelServlet)
Any thoughts on that?
thanks,
robert
P.S.: here's the stacktrace:
com.signal7.procurement.struct.administration.UnitData is in the same jar
file as the servlet
java.lang.ClassNotFoundException: com.signal7.procurement.struct.administra
tion.UnitData
