Hello Nial, Thanks for your comment and if you feel uncomportable from my long mail I apolozy for this.
But your comment didn't help. The reason why I set MaxObjects=0 is that I would like to test IndexedDiskCache only. I bollowed the test configure from http://svn.apache.org/viewvc/jakarta/jcs/trunk/src/test-conf/TestDiskCacheNoMemory.ccf?revision=536904&view=markup As I understanding the MaxObjects property is controlled by Memory cache how may item can have. http://jakarta.apache.org/jcs/RegionProperties.html and at the IndexedDiskCache the similar property for the controll amount item to handle is that maxKeySize which I set maxKeySize=1000000 http://jakarta.apache.org/jcs/IndexedDiskCacheProperties.html For the test, If I put whole item into Memory cache by setting MaxObjects=100000 than the test is PASS. But it is Memory cache usage Not IndexedDiskCache. Probably I have some miss configure or mis understand for my test. I don't know the reason, But I have to understand and solve this problem.
