Hi we are using JBoss 4.0, hibernate 3.0, in our application. We are using hibernate second level cache and now we want to use Query Caching in our application. We are using FileCacheLoader for caching. When we try to cache a query, it is giving the following exceptions:
Code:

I think the problem is that while saving the cache as a file, it is passing the whole SQL query as the key to the file name and so unable to create a file, it is giving FileNotFoundException. Can somebody please help me out here.
Thanks,
