Hi All,
I'm new to JCS. I've a web application where objects will be cached
offline(over night job). When i try access them online i'm getting
java.lang.ClassNotFoundException.
I'm using Index Desk caching. One more observation, when use custom
class(com.ebusiness.modules.reviewIndexes.valueObjects.ResultObject in this
case) i used to get this exception. Please advise me on this.
Here is the complete Exception and my cache.ccf file.
java.lang.ClassNotFoundException:
