Hello,

I've got a problem with JDBCCacheLoader and run out of ideas. Therefore any 
help will be appreciated.

We are using JBoss Cache 3.0.0 and our application is EJB module, being 
deployed to WebSphere 6.1. Oracle is used as database, and data source is 
managed by the application server

At initialization (processing of first request) we are getting exception from 
Oracle:


  | Caused by: org.jboss.cache.CacheException: Unable to start cache loaders
  |     at

The exception seems to be valid - transaction should not be committed here. 
However why does the loader try to createDummyTableIfNeeded ?

Its configuration seems to prevent from creation of the tables (these tables 
are actually already in the database after running the same code outside 
application server)


  |     <loaders passivation="false" shared="true">
  |             <preload>
  |                     <node fqn="/" />
  |             </preload>
  |             <loader class="org.jboss.cache.loader.JDBCCacheLoader"

  |                     </properties>
  |             </loader>
  |     </loaders>

Just in case, I'm posting below the last DEBUG message before exception trace 
(the last line is from our code):
