Subject Re: Using Application server JAAS auth alias and datasource for JDBCDiskCache
Date Tue, 19 Aug 2008 01:01:25 GMT
Take a look below... It looks like JCS bypasses the use of JNDI datasources
(handy feature for applications not running in a Appserver) and provides its
own implemenation of the concept.  Look at what is highlighted below...
Perhaps try the JNDI url for the "url" and a table name of [emptyString]?
Long shot... but worth a shot... If not a feature enhancement request.

JDBC Disk Configuration Properties PropertyDescriptionRequired Default Value
MaxPurgatorySize The maximum number of items allowed in the queue of items
to be written to disk. N5000 url The database url. The *database name will
be added to this value to create the full database url*. Y
databaseThis is appended to the url.Y
driverClassName The class name of the driver to talk to your database. Y
tableNameThe name of the table.N JCS_STOREtestBeforeInsert Should the disk
cache do a select before trying to insert new element on update, or should
it try to insert and handle the error. Ntrue maxActive This sets the maximum
number of connections allowed. Y
allowRemoveAll Should the disk cache honor remove all (i.e. clear) requests.
You might set this to false to prevent someone from accidentally clearing
out an entire database. Ntrue UseDiskShrinker Should the disk cache try to
delete expired items from the database. Ntrue ShrinkerIntervalSecondsHow
often should the disk shrinker run.N 300

*** Also note: *If you are talking about the JCS cache for hibernate the
following is relevant...
*"By default, Hibernate uses EHCache for JVM-level caching. (JCS support is
now deprecated and will be removed in a future version of Hibernate.)"*

*Table 19.1. Cache Providers*
