Hi Jennifer, I've never actually seen that error before either. But, a little bit of Google searching seems to imply that somehow your XMLUI/Cocoon Cache has been corrupted (not sure what the cause could have been though).
http://web.archiveorange.com/archive/v/fTi8LIEB3AxnszySzs8E The solution they give is to actually remove your Cocoon Cache altogether and restart the web application. To clear you XMLUI/Cocoon Cache in DSpace, you'd do the following: (1) Stop Tomcat (2) Go into Tomcat's 'work' directory, and look for a folder named "xmlui" (or whatever the name of your XMLUI webapp folder is, if you renamed it). It likely should be at a path similar to: [tomcat]/work/Catalina/localhost/xmlui/ (This path may be slightly different based on how your Tomcat is configured locally) (3) Inside that "xmlui" folder, you'll find a "cache-dir" folder. This folder contains the Cocoon Cache (you'll see files named 'cocoon-ehcache.*' in that folder). Delete that entire folder and all its contents. (4) Now, restart Tomcat. As XMLUI/Cocoon starts back up, it will recreate its cache automatically. I've been looking around on the web to see if there's any easier way to do this (without having to reboot Tomcat), but it doesn't seem like there is. Good luck. Let us know if this resolves the problems or not. - TIm On 7/12/2011 5:27 PM, Jennifer Whalan wrote: > Just having a look through the logs today, I've noticed a lot of a > particular error popping up.
