I think i found the cause. On the redeploy i get 2 log statements like so anonymous wrote : | 2008-01-24 10:46:52,602 DEBUG [org.jboss.cache.loader.JDBCCacheLoader] executing ddl: drop table jbosscache^M | and later on i get anonymous wrote : | 2008-01-24 10:47:19,415 DEBUG [org.jboss.cache.loader.JDBCCacheLoader] executing ddl: create table jbosscache(fqn varchar(255) not null, node blob, parent varchar(255), constraint jbosscache_pk primary key (fqn))^ | So this would explain why the DB is purged, because the table is dropped!! Why this gets executed, i dont know!!! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4122949#...
