Re: Nulll point exceptino while configuring EHCache
Yes, this is because the EhCacheManager cannot be configured via the
current text configuration.
It requires an init() method to be called and the simple text-based
.ini configuration does not (currently) perform lifecycle
initialization like that.
We're discussion on the development list what our alternatives could/should be.
In the mean time, please open a Jira issue for this so we can keep
track of it. You'll probably have to set the EhCacheManager on the
security manager in code until it is fixed.
Thanks,
Les
