#292 Occasional ClassNotFoundException exception

[Dansong Chen]

We are using Java Service Wrapper 3.0.5 (WrapperSimpleApp) in for Windows XP, Java 6. The application is a file watcher with read/write to database. Most of time it runs file but occasionally it throws error then it hung. We have to restart the service. Given the fact service runs fine most of the time, I am not sure why the exception complains the ClassNotFound. It is in the jar file specified in the config. Any help is highly appreciated.

Thanks,

Dansong
