I am writing an object to the cache that I get as a response from a soap call (using
apache axis). The object implements Serializable and are auto generated using the wsdl.
While reading the object (using get ) back from the cacheloader (jbdc) I get
CacheException. As long as the object is in memory there is no problem getting the object
but ones it is evicted from the memory and I try to read it back the exception shows
