Sandeep I have worked on it (symmetricDS) and facing the following problem
what i have done is
1. extracted the zip file in a folder
2. created a sample database on two systems.
but when i try to execute under mentionded command i get exception. As Exception is self explanatory I did as it says. I added the custom varaible classes in postgresql in postgresql.conf file but still get the same exception.
I have restarted the postgresql service (as well as system). Still no use. Please help how to use it
./sym -p root.properties --auto-create
