Hi Aaron,
I'm getting the CacheException while trying to cache an object.
Here's the piece of code I've been working with.
import org.apache.jcs.JCS;
import org.apache.jcs.access.exception.CacheException;
public class Main {
/**
* @param args
*/
public static void main(String[] args) {
Person mary_ = new Person("MARY");
//Create an instance of the Cache Hnadler
JCS cache = null;
try{
cache = JCS.getInstance("testCache1");
if(null == cache)
{System.out.println("cache= null");}
//Insert the objects into the cache
if(null == mary_)
{
System.out.println("the object is null");
}
System.out.println("b4 put");
String key = mary_.toString();
System.out.println(key);
cache.put(key, mary_);
System.out.println("after put");
}
catch(CacheException CE)
{
System.out.println("caught exception "+ CE.getCause());
}
if(null != cache)
{
cache.get(mary_.toString());
}
}
}
class Person
{
private String name;
Person(String str)
{
name = str;
}
public String toString()
{
return name;
}
}
My configuration file is as follows:
(no new lines this time)
# DEFAULT CACHE REGION
jcs.default=DC
jcs.default.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
jcs.default.cacheattributes.MaxObjects=1000

# PRE-DEFINED CACHE REGIONS
jcs.region.testCache1=DC
jcs.region.testCache1.cacheattributes=org.apache.jcs.engine.CompositeCacheAttributes
jcs.region.testCache1.cacheattributes.MaxObjects=1000
jcs.region.testCache1.cacheattributes.MemoryCacheName=org.apache.jcs.engine.memory.lru.LRUMemoryCache
# AVAILABLE AUXILIARY CACHES

jcs.auxiliary.DC.attributes.MaxRecycleBinSize=5000
jcs.auxiliary.DC.attributes.OptimizeAtRemoveCount=300000
And.. here's the output:

INFO: Disk cache was not shutdown properly. Will try to dispose.
NOTE: The above program works fine if I cache simple strings but it fails
if I use objects as in the above program.
Could you help me with this please..
