The following table describes properties for the default-helper element.
Table A–37 default-helper Properties|
Property |
Default |
Description |
|---|---|---|
|
Uses the built-in default cache-helper key generation, which concatenates the servlet path with key-field values, if any. |
The caching engine looks in the ServletContext for an attribute with a name equal to the value specified for this property to determine whether a customized CacheKeyGenerator implementation is used. An application can provide a customized key generator rather than using the default helper. See CacheKeyGenerator Interface. |
