Is it possible to configure a cache without using the cache.ccf file? I've
tried instantiating a CompositeCacheAttributes object, setting its
attributes, and passing to JCS, but I get a NullPointerException.
Here is a snippet of what I'm trying to do:
CompositeCacheAttributes attributes = new
CompositeCacheAttributes();
attributes.setCacheName("udrCache");
attributes.setMaxObjects(50);
attributes.setMemoryCacheName("org.apache.jcs.engine.memory.lru.LRUMemoryCac
he");
attributes.setUseDisk(false);
attributes.setUseLateral(false);
attributes.setUseMemoryShrinker(false);
attributes.setUseRemote(false);
JCS udrCache = JCS.getInstance("udrCache",
createCacheAttributes("udrCache"));
this gives me the following NullPointerException:
java.lang.NullPointerException
