Hi,
I have configured JDBCCacheLoader with POJOCache , but the CacheLoader is not
persisting the cache in the database.
My Jboss Cache version is 1.4. And I am using MySQL as database.
The configuration code is as follows:
<!-- if passivation is true, only the first cache loader is
used; the rest are ignored -->
<!-- Enabling the activation\passivation -->
true
<!-- comma delimited FQNs to preload -->
/
<!-- are the cache loaders shared in a cluster? -->
false
<!-- we can now have multiple cache loaders, which get chained
-->
<!-- the 'cacheloader' element may be repeated -->
org.jboss.cache.loader.JDBCCacheLoader
<!-- same as the old CacheLoaderConfig attribute -->
cache.jdbc.table.name=jbosscache
cache.jdbc.table.create=true
cache.jdbc.table.drop=false
cache.jdbc.table.primarykey=jbosscache_pk
cache.jdbc.fqn.column=fqn
cache.jdbc.fqn.type=varchar(255)
cache.jdbc.node.column=node
cache.jdbc.node.type=longblob
cache.jdbc.parent.column=parent
cache.jdbc.driver=com.mysql.jdbc.Driver
cache.jdbc.url=jdbc:mysql://localhost:3306/tg_schema
cache.jdbc.user=root
cache.jdbc.password=passw0rd#
<!-- whether the cache loader writes are asynchronous -->
false
<!-- only one cache loader in the chain may set
fetchPersistentState to true.
An exception is thrown if more than one cache loader
sets this to true. -->
true
<!-- determines whether this cache loader ignores writes -
defaults to false. -->
true
<!-- if set to true, purges the contents of this cache
loader when the cache starts up.
Defaults to false. -->
false
The cacheable objects are serializable.
The code for building the cache is :
private PojoCache pojoCache;
pojoCache.putObject(fqn,cacheObj);
I am able to build the cache but CacheLoader is not persisting it in the
database. I am not getting any clue as whree could things go wrong.
P.S. Instead of PojoCache's putObject if I use TreeCache's put method.
i.e.
pojoCache.put(fqn,regionName ,cacheObj);
then the persistence happens. Does this mean that
org.jboss.cache.aop.PojoCache does not support CacheLoaders.
Please help.
Thanks
