Hi, I have started implementing JBossCache/PojoCache and stumble to the following:
I (basically) use the config files as provided through the samples. I also play with PojoCache 2.0. Java 1.5 The Config files are below and I use the annotations as described. The issue is the following: I have an application that is very memory consuming so I try to cache the overflow of objects to disk. As you can see I set the cache mode to be LOCAL, cacheloader is JdbmCacheLoader is and marshallNonSerializable = true. 1. After closing the app I expect the table to be cleared but somehow this does not happen. 2. From what I understand my objects don't need to be serialized but when I don't do this jboss complains: Jun 12, 2007 4:40:42 PM org.jboss.cache.eviction.BaseEvictionAlgorithm evictCacheNode | SEVERE: Eviction of /__JBossInternal__/9e13ccf9-0908-4234-bd1f-cf0f1deea048/1426servoy_sample_auto_pdf-1/_ID_/5c4o16-rj0vpp-f2uhehnn-1-f2uhehq1-3 failed | java.lang.RuntimeException: java.io.NotSerializableException: com.it2be.analyzer.repository.Style | at org.jboss.cache.CacheImpl.invokeMethod(CacheImpl.java:3860) | ..... 3. Serializing then is not the solution either. After a while (I guess when caching to disk really takes place) I see the following error:Jun 12, 2007 5:01:42 PM org.jboss.cache.eviction.BaseEvictionAlgorithm evictCacheNode | WARNING: Eviction of /e9737027-7423-45ad-b3d7-87a5f5be2174 timed out, retrying laterand ultimately, out of the blue, I receive the next error where the class is exactly the same as the ones before:Jun 12, 2007 5:02:46 PM org.jboss.cache.pojo.interceptors.PojoTxInterceptor invoke | WARNING: attach: exception occurred: java.lang.RuntimeException: java.io.InvalidClassException: com.it2be.analyzer.repository.Method; no valid constructor I am new to caching so I hope you forgive me my ignorance and hope you can help me to solve these issues.
