Re: [Wrapper-user] Java service - windows service recovery?

[Sandeep K. <san...@vi...>]

Hi,

Thanks for the prompt response. After visiting
http://sourceforge.net/tracker/index.php?func=detail&aid=852491&group_id=39428&atid=425190

I tried using WrapperManager.stop(-1) directly. On the console it showed
that the JVM and eventually the wrapper exited with -1. But, when I run
the same as a Windows service, the service just starts and stops
normally without compaining about anything! 

Is there a specific exit code/codes for the Windows service manager to
identify a service failure? A quick search on google did not reveal
anything also.

I appreciate your other suggestion about a seperated class and sending
recovery mail using Java mail. Unfortunately, we wouldn't be going that way.

Thanks in advance,
Sandeep Khanna
