Subject Problem with the Jispfilestore?
Date Mon, 04 Aug 2003 10:57:01 GMT
Hi list,

has anybody experienced problems with the Jispfilestore? It seems that 
the store loses sometimes its content after a while. Calling a status 
page (Statusgenerator) produces the attached exception. I'm not able to 
reproduce the error.
Cheers,
   Matthias Stöckel

System Configuration:
- Cocoon 2.1m2
- JDK 1.3.1
- Solaris
