Problem with EhCacheManager

[Krishan Senevirathne <kr...@gmail.com>]

Hi, I'm trying to use EhCacheManager implementation to do caching.
In my .ini file I'm having

cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
securityManager.cacheManager = $cacheManager

shiro-ehcache.jar and ehcache1.5.0.jar in my class path

but I'm getting an exception. Here is the stack trace
SEVERE: Unable to start Filter: [Unable to set property 'cacheManager' with
value [$cacheManager] on object of type
org.apache.shiro.web.mgt.DefaultWebSecurityManager.  If '$cacheManager' is a
reference to another (previously defined) object, prefix it with '$' to
indicate that the referenced object should be used as the actual value.  For
example, $$cacheManager].

I can't figure out the problem.
Is there any problems with my implementation??

Thanks in advance

Hi Krishan,

Ehcache 1.5 is pretty old.  Shiro is compiled against 2.3.0.  Try that
and see how it works.

As a test, I ran the basic Shiro sample web app here:
http://svn.apache.org/repos/asf/shiro/trunk/samples/web/

I modified the pom to depend on Shiro's shiro-ehcache .jar and then
added the following to the WEB-INF/shiro.ini file at the end of the
[main] section:

sessionManager = org.apache.shiro.web.session.mgt.DefaultWebSessionManager
sessionDAO = org.apache.shiro.session.mgt.eis.EnterpriseCacheSessionDAO
sessionManager.sessionDAO = $sessionDAO
securityManager.sessionManager = $sessionManager

cacheManager = org.apache.shiro.cache.ehcache.EhCacheManager
securityManager.cacheManager = $cacheManager

It all started/worked fine.

HTH,

Cheers,
