com.bea.p13n.cache.servlets.CacheManagerServlet
- All Implemented Interfaces:
- Serializable, Servlet, ServletConfig
- public class CacheManagerServlet
- extends HttpServlet
A servlet which can interact with the p13n caches.
This obeys the 'opeartion' query parameter:
- 'set': set the attributes of the cache specified by 'name'. Will use
the query parameters 'enabled' ('true' or 'false'), 'maxentries', 'ttl',
and 'description' to set the cache attributes. This will use the
CacheFactory; therefore, setting on a cache that doesn't exist will
initialize that cache (temporarily if there isn't a corresponding
CacheMBean entry).
- 'flush': flush the cache specified by 'name'. If 'type' is 'local' only
the local cache will be flushed (if it's been created yet); otherwise,
flush the cache on all machines. This will use the Cache object and the
CacheManager.
- 'get' (or anything else): will return the attributes of either the
cache specified by the values of 'name' or all (if no 'name' specified).
This will use the MBeans to get the values.
The output will be text/xml, like:
<caches>
<cache>
<name>...</name>
<enabled>...</enabled>
<max-entries>...</max-entries>
<ttl>...</ttl>
<description>...</description>
</cache>
</caches>
with the contents depending upon the opearion. 'flush' will only return
<cache><name>...</name></cache> blocks for each
cache flushed. 'set' will return a complete <cache></cache>
block with the new values for the cache (can be used to determine if one
didn't get set); if there isn't a corresponding CacheMBean for the cache,
then <description> wont' be sent back.
'get' will return <cache></cache> for each cache that has an
MBean entry.
