Ive been using OJB for a while now and am very impressed (I once wrote an ODMG
implementation, but thats another story).
Im having a problem, configuring OSCache with OJB
Im using :
- OJB rc5
- OSCache 2.0.2 and included Javagroups
Ive followed the instructions and on Linux everything works fine. However, when
I try to run on NT I get the attached error (bottom).
Ive run the multicast test programs and they work fine (ie. I can use
multicast).
Ive searched the news groups for a similar problem, but come up blank.
I need to get my application running on NT, so advice would be appreciated. Im
not really sure whether this is an OJB or OSCache problem, but the stack trace
points to OJB.
Kindest regards,
Andrew.
